FOREWORD
FOREWORD
The core research mission of the National University of Singapore
is to establish a sound base of internationally competitive research,
build peaks of research excellence, grow effective global research
links and provide strong linkages between research and graduate
education.
In line with this, the Yong Loo Lin School of Medicine continues to
contribute to the understanding of factors involved in triggering
diseases common in Singapore, and through research, determine
ways to prevent their onset through early diagnosis and strategies
to either retard or reverse the consequences. This is being fulfilled
through the School’s focus on translational research – the clinical
application of basic science discoveries from bench to bedside.
As part of a comprehensive academic university campus with access
to patient materials from the adjacent National University Hospital
and research collaborations with the Biopolis, the School is uniquely
positioned to validate new drugs, devices and biomarkers.
2005 marks the 100th anniversary of the founding of the Faculty
of Medicine, the oldest body of tertiary education in Singapore
which laid the foundation for the development of what is now the
National University of Singapore. Our centennial year was marked
by the unprecedented donation of $100 million to the Faculty of
Medicine by the Yong Loo Lin Trust. This was matched dollar for
dollar by the Government, resulting in a $200 million sum providing
the resources to transform our Medical School from Asia’s foremost
to one comparable with the best in the world. In honour of this
transformational gift, the Faculty of Medicine was renamed the Yong
Loo Lin School of Medicine.
The donation has since enabled the establishment of new
infrastructure and state-of-the-art facilities, and accelerated the
development of a number of research areas significant to Singapore’s
health needs: cancer, cardiovascular diseases, infectious diseases and
neuroscience.
We also wish to highlight the research achievements of the following
faculty members. One of Asia’s leading surgeons in hand surgery
and bone and muscle tumours, Professor Robert Pho, from the
Department of Orthopaedic Surgery, was conferred Emeritus
Professorship in July 2005, in recognition of his distinguished
scholarship and conspicuous service. Professor Ariff Bongso,
Department of Obstetrics and Gynaecology, was awarded the
ASEAN Outstanding Scientist Award, for his contributions to the
field of embryonic stem cells. Dr Leonard Ang from the Department
of Opthalmology won the 2005 Singapore National Academy of
Science (SNAS) Young Scientist Award.
Professor Shazib Pervaiz, Department of Physiology, and Associate
Professor Marie Veronique Clement, Department of Biochemistry,
were honoured with the NUS Outstanding Researcher Award
(Team Award) in 2005 for their work involving the role of reactive
oxygen species in apoptotic cell death. Professor Yong Eu Leong,
Department of Obstetrics and Gynaecology, Dr Lynette Shek and
Dr Allen Yeoh, both from the Department of Paediatrics, received
the inaugural Clinician Scientist Award sponsored by the Agency
for Science, Technology and Research (A*STAR) and the Ministry of
Health’s National Medical Research Council. Meanwhile, Professor P
Gopalakrishnakone from the Department of Anatomy was appointed
as a Principle Fellow in the Department of Pharmacology, Australian
Venom Research Unit, University of Melbourne.
Professor Philip Moore, Vice Dean for Research and Graduate
Studies and Head of the Department of Pharmacology, was invited
to join the Editorial Advisory Board of Current Medicinal Chemistry,
a leading international journal. The World Scientists Forum awarded
Dr Manuel Salto-Tellez from the Department of Pathology with
the “Eminent Scientist of the Year 2005” title in honour of his
contributions in the field of gastrointestinal and oncopathology.
In terms of research output, the faculty continued to win strong
funding support from external funding agencies such as the
Biomedical Research Council (BMRC) and the National Medical
Research Council (NMRC), garnering over $39 million in research
funding for FY 2005. In 2005, the School also continued to publish in
leading international journals with the number of publications (Tier 2
and above) increasing by almost 20% from previous year.
2005 had been a transformational and fruitful year, yielding new
opportunities and resources to support the School’s pivotal role in
the Biomedical Sciences Initiative. The next few years will be critical
as our Nation continues to develop in the Biomedical Sciences,
and as we strive to keep the School relevant in this changing era of
academic medicine.

helicobacter_pylori.shtml
Research theme
To identify molecular mechanisms of pathogenesis of Helicobacter
pylori and improve treatment.
Specific themes
1. Molecular mechanisms of H. pylori pathogenesis.
2. The use of probiotic/prebiotics as alternative therapeutic strategy.
Programme activities
1. Molecular mechanisms of H. pylori pathogenesis
A cytoplasmic enzyme 1 (CE1) has been identified to be strongly
associated with patients having peptic ulcer disease (p<0.001).
Purified native CE1 exhibited significantly higher cell apoptosisinducing activity (p<0.05), induces H2O2 generation and elevated
interleukin-8 production by activating NF-KB in gastric epithelial
cells. These findings show that CE1 may play an important role in
the pathogenesis of H. pylori-associated severe gastric diseases
(unpublished data).
Another surface localized enzyme (SE1) was shown to interact with
CagA by co-IP. It was shown that SE1 acted in concert with CagA
affecting the tight junction protein, ZO-1 of T-84 and AGS cells. A
comparison study of cagA+, cagA- and isogenic mutant (SEI knock
out) H. pylori strains was performed using confocal microscopy and
functional study based on the tracking of leakage of biotinylated
albumin across cell monolayer. The results suggest a probable
chaperonic role of SE1 in assisting CagA-mediated ZO-1 recruitment,
indicating the potential role of SE1 in facilitating H. pylori invasion into
the host mucosal, leading to pathogenesis (unpublished data).
2. The use of probiotic/prebiotic as alternative therapeutic
strategy
With antibiotic-resistance on the rise over the years, the
development of effective alternative therapy is important. Results
from the studies of “generally regarded as safe” microalgae and
microalgae sulfated polysaccharides show that they are effective in
detaching H. pylori from the surface of tissue cultured cells and is
bactericidal to H. pylori at concentrations that do not harm tissue
cultured cells. It indicates that these ‘pro-/prebiotics’ may potentially
be used as anti-adhesive and bactericidal agents.

Research theme
Repair and Regeneration of Musculoskeletal Tissues.
Programme activities
1) Isolation, Culture and Characterization of Mesenchymal
Stem Cells (PI: Prof EH Lee)
It has been reported that adipose tissue is an alternative source of
MSCs, and that adipose tissue-derived MSCs (AMSCs) are capable
of differentiating into multiple lineages. As BMSCs are not so easily
obtained, the research group decided to examine AMSCs and
compare them with BMSCs. AMSCs and BMSCs were studied in
terms of their cell-surface marker expression, their differentiation
potential and their expression profiles using a wide range of
techniques including flow cytometry, immunostaining, histology, realtime RT-PCR and microarray analysis. These studies showed that
surface-marker expression could be used to isolate subpopulations
of MSCs with enhanced colony formation capabilities. Expression
profiling showed that BMSC and AMSC express many common genes,
however chondrogenic differentiation studies showed that BMSCs
are superior in inducing chondrogenic differentiation to AMSC.
2) Chondrogenic Differentiation of Mesenchymal Stem Cells
(PI: Prof EH Lee)
The team has been studying the differentiation of chondrocytes for
repair of articular cartilage as well as for repair of physeal or growth
plate cartilage. Novel in vitro methods for chondrogenic differentiation
of BMSCs are currently being fully characterized and promise to
provide tools for unraveling the macro-molecular processes involved
in articular and physeal chondrogenic differentiation. In particular, the
team has been able to induce MSCs to differentiate into physis-like
tissue which contains the many different cartilage cell types found
in normal physis. In parallel, conditions for maintaining the stable
phenotype of chondrocytes are investigated to obtain cells suitable for
transplantation in articular cartilage. In addition, we have developed
systems and are studying the effects of various extracellular matrix
components on BMSC proliferation and differentiation.
3) Tendon and Ligament (PI: Assoc Prof James Goh)
PLLA and PLGA have been extensively investigated as possible
materials for ligament tissue engineering applications by the group.
However, PLLA and PLGA tissue-engineered tissues demonstrated
inferior mechanical properties and rapid degradation rates compared
to the normal tissue.The extraordinatory mechanical properties and
enhanced environmental stability of silk make silk fibroin (core of
silk) to surpass the costly PLLA and PLGA, as potential biomaterial
for ligament tissue engineering applications in orthopedic research.
To avoid the immune response elicited by the sericin and improve
the biocompatibility of silk fibers, the group has modified the sericinfree silk fibers with gelatin and crosslinked with NDGA. The physical
properties and biocompatibility of modified silk fibers and native
silk fibers were compared using in vitro and in vivo models. A new
modified knitted silk scaffold will be tested in vitro and used to
reconstruct ACL in rabbit and pig model. In addition, the group has
designed a bioreactor to provide cyclic tensile stimulus to enhance
orientation of the cells and collagen fibers for engineering ligaments.
The system is under debugging.
4) Spine (PI: Prof Wong Hee Kit)
In 2005, nine (9) (out of 42) animals (pigs) were operated and
sacrificed end of 2005. The samples have been analyzed and the
intermediate interest has been concentrated on the improvement
of the biomaterial handling including optimized seeding and culturing
techniques for the stem cells plus growth factors. Samples underwent
micro CT, x-ray, bone density and histological analysis. Biomechanical
analysis is in preparation. The investigated animals show an
improvement of spinal fusion capability by using our new designed
PCL-TCP biomaterial after six months compared to the results of
the control group using bone autograft. These short term data have
to be confirmed by the long term data and have to be tested for
statistical significance.

Research theme
From Venoms to Drugs, From Toxins to Therapeutics.
Programme activities
In general,
purification, biochemical and pharmacological
characterization as well as molecular aspects of research involving
cloning, sequencing and expression of new toxins are actively being
done by the academic staff with the help of research fellows, research
assistants and postgraduate students. A range of novel toxins from
different species of scorpions, spiders and cone shells have been
isolated, purified, sequenced and the synthetic toxins being screened
for novel biological activities. Several channel toxins, specific for sodium,
potassium or calcium channels, have been extensively studied with
respect to their structure, mode of action, and localization of the
functional site. In particular, a programme combining combinatorial
chemistry, analogue screening, NMR and molecular docking along with
the use of clinically relevant animal models has been implemented for
the development of optimized lead peptide with therapeutic potential
for rheumatoid arthritis. Crystallographic studies of phospholipase A2
toxin from Daboia russelli siamensis venom have also been done. Antimicrobial peptides against B. pseudomallei have been screened from
the venoms and toxins of various species of snake, scorpion, spider,
and cone snails. The role of PLA2 as a target in melioidosis and its
inhibition by PLA2-inhibitory peptides have been explored along with
cytokine gene expression studies in acute infection and in response to
treatment with potential bactericidal agents using mouse model and
DNA microarray. Establishment of global gene expression profiles of
human neuronal cell lines following exposure to sarin is in progress
using DNA microarray technology.

INTRODUCTION
Epidemiology of Chronic Diseases:
The Department continues to focus on the epidemiology of chronic diseases, in particular cancer, cardiovascular
disease and myopia. This area of focus is led primarily by the Centre for Molecular Epidemiology (CME) & Centre
for Environmental and Occupational Health Research (CEOHR). CME continues to maintain and develop its
cohort studies. This is augmented by CEOHR efforts in its mechanistic studies and biomarkers studies.
To further enhance this area of research, a new research collaboration was established with Karolinska Institute (KI).
This has resulted in a comparative breast cancer research programme as well as a joint PhD in Genetic and Molecular
Epidemiology.
The Centre for Molecular Epidemiology launched the Singapore Consortium of Cohorts Study for translational
research on Jan 1, 2006 with a $12m BMRC grant. The Consortium will bring together several existing cohort
studies with data on exposure and biospecimens. The short-term target is to develop a multi-ethnic cohort of 12,000
subjects and a diabetic cohort of 10,000 patients. The data and specimens will be used to discover gene-environment
interactions of public health significance.
Research activities by the Centre for Molecular Epidemiology received an excellent rating by its visiting International
Scientific Advisory Board in 2004. This tremendous endorsement confirms that we are progressing on the right track
and heralds greater success in the future.
Department of Community, Occupational and Family Medicine
Health Service Research:
Prof Lee Hin Peng is Chairman of the Health Services Research
Workgroup in the Yong Loo Lin School of Medicine. The Health
Services Research Unit continues to focus on health policy and
evaluation research, with strategic thrusts in comparative health
systems and health economics and financing. The Unit contributed
to a recent WHO-sponsored study on comparative health care
financing and health insurance in Asia and the Pacific and participated
in several regional health and population studies with the Asia
Research Institute and the Faculty of Arts & Social Science, NUS.
It also continued to participate in on-going studies of comparative
health systems and reforms internationally through the International
Network on Healthcare Reform, and in the Asia-Pacific region through
DRAGONET (Asian Health Systems Reform Network). A workshop
on Pharmacoeconomics and Outcomes Research was organized
jointly with the Pharmacy Department in March, 2005. There is
much interest in applying economic evaluation methods in the health
care industry. The unit hopes to develop even greater capacity and
expertise for such potential areas of growth in the future.
Niche area research:
Work of the Salivary Biomarkers Group in COFM promises to develop
into a niche research area. The group is currently studying salivary
biomarkers in numerous conditions such as stress, periodontal disease,
psychiatric conditions, asthma and occupational diseases among others.
Successful collaborations have been forged with the NUS Paediatrics
and ENT Departments, the School of Design and Environment, the
National Skin Centre, and the Faculty of Dentistry. The potential for
saliva research was recognized with the award of a substantial Niche
Area Programme Grant from the Yong Loo Lin School of Medicine in
August 2005 to fund its research on the use of salivary biomarkers in
various medical conditions and across different age groups.
Publications in 2005 and Future Directions:
In the year 2005, 115 papers were published in international refereed
journals. The Department will focus on epidemiology of chronic
diseases and translational research in the coming years. We have done
well in securing research funding and papers by staff are appearing in
higher impact journals. Among our new initiatives, the SEED (Singapore
Epidemiology of Eye Diseases) program was established as a Faculty
level programmatic research area.
A positive research indicator is an estimate of our laboratory space
projections for the next decade. In this exercise, it was forecast that a
doubling of physical space is required based on current and proposed
projects, pointing to the existence of long term research plans
particularly in the areas of genetic and molecular epidemiology.

RESEARCH REPORT 2005
Department of
Diagnostic Radiology
Introduction
Our department’s research is strongly multidisciplinary, a feature of Radiology both as
a clinical specialty and a research discipline. In 2005 we continued to expand, with new
research collaborations between our department and the NUS Departments of Chemistry,
Microbiology, Chemical Engineering, Electrical Engineering, Psychology, the Division of
Bioengineering and the School of Computing, as well as the Faculty of Engineering at NTU.
Our research and collaborations are concentrated on these themes with these specific
projects:
1. Breast cancer imaging diagnosis & tumour biology.
(a) MRI and in vitro MRS of ductal carcinoma in situ.
(b) MRI and Sestamibi scintigraphy for detection of multidrug resistance in breast cancers
undergoing neoadjuvant chemotherapy.
2. Clinical applications in image recognition, reconstruction & quantitation.
3. Body imaging for disease detection, quantitation and staging using multislice CT and MRI.
4. Development and testing of magnetic nanoparticles for cellular tracking in vivo
(collaboration with Chemical Engineering, Materials Science & Engineering and Obstetrics
& Gynecology at NUS as well as Engineering at NTU).
Department of Diagnostic Radiology
There are also other specific areas of research enquiry, viz.,
1. Development & validation of functional MR urography in children
(collaboration with Paediatrics at NUS).
2. Development of a paediatric Asian bone age atlas (collaboration
with Orthopaedics at NUS).
3. Functional and structural brain imaging for psychological research
(collaboration with Psychology at NUS).
4. Imaging of transplanted articular cartilage repair in the knee
(collaboration with Orthopaedics at NUS).
5. Development of simulation systems for image-guided biopsy and
therapy (collaborations with Mechanical Engineering at NUS and
STAR Labs at NUH).
The clinical work and research of our department is intricately
entwined with that of the Department of Diagnostic Imaging in the
National University Hospital. As such, most of our research involves
collaboration between the University and Hospital departments and
their staff, and is difficult to completely separate.

DEPARTMENT
OF Medicine
INTRODUCTION
Year 2005 has been most fruitful for staff members under the Department of Medicine. Many of the academic
and research staff have been able to build links both within the School and also across faculties and institutions
to bolster their research initiatives. With such strong capabilities in our clinical, teaching and research arena, the
Department has been able to champion its research in the life sciences, especially in areas that have significant
implications for the health of the community in Singapore.
The Department has succeeded in garnering a cheering amount of competitive research funding amounting to
more than $16 million in 2005. The main areas with significant funding remain in liver diseases, gastrointestinal
disorders, cancer and cardiovascular diseases but respiratory medicine leads the charge in health services.
Research output has rebounded following 2004 with more than 140 full papers published in 2005. Of note, these
are quality publications in premier journals, having more than 50% papers tiered at first or second grades. Worth
mentioning, the Department has made its mark with publications in the prestigious New England Journal of
Medicine in 2005. Apart from publications, it is also noteworthy as 10 of our staff members had won awards for
their work. One of our research students had been awarded PhD while two others received their MSc.
For the coming year, we seek to build on these successes and continue to be a major catalyst for clinical, translational
and basic research within the University.

DEPARTMENT
OF Microbiology
INTRODUCTION
In recent years, research on immunology, genetics, virology, bacteriology, applied and industrial microbiology has
progressed further, while scientific collaborations both within Singapore and overseas have developed. Located
within the department are the WHO Collaborating Centre for Research and Training in Immunology; Bone Marrow
and Cord Blood Registries; MOH Hepatitis B Testing Quality Assurance Centre; National Malaria Reference Centre
and the Human Genome Laboratory. To take advantage of the completion of the sequencing of the human genome
and many microbial genomes, the department is concentrating on microbial pathogenesis and on the development
of molecular-based microbial diagnostics and vaccines. We are also involved in a bioengineering initiative in which
bioinformatics and computational biology are utilized to unravel the interaction between microbial peptides and
the host major histocompatibility antigens. Such precise biocomputational prediction may generate vaccines and
immunotherapeutic procedures against important infectious diseases and cancers. The department is blending
powerful tools developed in the physical and computational sciences into biology to develop cutting-edge capabilities
in the Life Sciences.
Department of Microbiology
The Department of Microbiology at the Yong Loo Lin School of
Medicine possesses a faculty and two major research programmes
that are internationally competitive. The international team of
researchers, led by Professor David Michael Kemeny, comprises
academics whose interests include basic research on Immunology;
Microbiology; Virology, Bacteriology; Parasitology/genetics and
molecular biology of prokaryotic and eukaryotic microorganisms,
microbial pathogenesis, and vaccine development. The two major
research programmes in the Department are the Immunology
and Infectious Diseases Programmes. Within these programmes,
there are six research themes. They are emerging/re-emerging
infections, tropical diseases, viral cancers, anti-infectives, vaccines
and immunobiology. A new Research Programme known as the
Microbiology Vaccine Initiative was launched to work on the
development of vaccines against major infectious diseases such as
dengue and tuberculosis.
The Department is strategically located on the NUS campus
between the Faculty of Science and the National University
Hospital, thus providing an excellent environment for
collaboration with investigators in both pre-clinical as well
as clinical fields. State-of-the-art core facilities and a vibrant
research community exist at the Department, and collegiality
among different laboratories is further fostered by the close
proximity of the Institute of Molecular and Cell Biology (IMCB),
Temasek Life Sciences Laboratory (TLL), Genome Institute
of Singapore (GIS) A*STAR, and Novartis (NITD). In addition,
top-tiered intensive research output is achieved by the
Department which synergistically and actively collaborates with
local external agencies as well as partner foreign universities.
Quality and world-class education in Immunology; Microbiology;
Virology, Bacteriology; Parasitology, Molecular Biology and
Infectious Diseases is offered to Medical, Dental and Life Sciences
undergraduates and postgraduates, ensuring that learning will
always be an exciting and challenging process at the Department.

RESEARCH REPORT 2005
DEPARTMENT OF
Obstetrics & Gynaecology
INTRODUCTION
This year was another fruitful year for translational research for Obstetrics & Gynaecology with landmark clinical
studies published in high impact journals. Several staff members have also won awards for their research work
as well as presentations at conferences. Significant and exciting research continues in the field of Maternal Fetal
Medicine, Reproductive Endocrinology and Gynaecological Oncology.
MATERNAL FETAL MEDICINE
Myopia & Breastfeeding: A landmark clinical study was published that significantly advanced our understanding
of the relationship between myopia and breast feeding.The fetal maternal medicine team led by Dr Chong Yap Seng
has made the first-time observation of the relationship between breastfeeding and myopia. This significant discovery
has resulted in a publication in the high impact journal, JAMA, and has great implications of the understanding of
the likelihood of myopia in Singapore children which is reaching epidemic proportions.
Misoprostol: Another important clinical study by Dr Su Lin Lin, showed the superiority of vaginal misoprostol
over the invasive intra-amniotic prostaglandins for midtrimester termination of pregnancy. This study will result in
significant cost savings for the Singapore population.
Department of Obstetrics & Gynaecology
Prenatal Diagnosis: Dr Mahesh Choolani and team are
researching on enrichment and identification of first trimester
fetal - erythroblasts from maternal blood for non-invasive prenatal
diagnosis; fetal erythroblast membrane proteome is studied to
identify unique surface antigen to improve enrichment. They are
working with the Institute of Bioengineering and Nanotechnology
in the development of a MEMS device for micro-filtration of cells.
REPRODUCTIVE ENDOCRINOLOGY
Botanical Drug Discovery Programme: Professor EL
Yong and his team published for the first time the discovery of a
new compound, Breviflavone B, from a traditional Chinese herb
Epimedium brevicornum. The compound and extract has strong
estrogenic activity and therefore is of potential use for menopausal
hormone replacement treatment. This botanical extract and its
compound have a special property of inhibiting the growth of
breast cancer cells. This extract and compound is of great interest
to the industry and a US patent has been granted for it. Clinical
developments are continuing in collaboration with Lilly-NUS
Centre of Clinical Pharmacology and with reputable botanical drug
manufacturers from Singapore and Germany. Several landmark
publications have already been submitted for reporting the results
of the clinical trial using the extract.
An International Congress on Complimentary and Alternative
Medicines (ICCAM) was organized from 26-28 February 2005, at
Raffles City Convention Center. THEME: Herbal medicines, ancient
cures, modern science. The Congress is the pre-eminent forum
for the cutting edge breakthroughs in botanical medicines, and to
facilitate scientific exchange between practitioners and scientific
researchers. Over 500 delegates from 26 countries registered
and over 130 abstracts received. This congress had over 18
invited foreign lecturers and 8 multidisciplinary symposia on the
development of botanical medicines.
Leiomyoma Study: His team has also studied the growth
dynamics of human leiomyoma cells from uterine fibroids. Uterine
fibroids are the most common benign tumour in women and are
responsible for causing huge disability in Singapore women. His
group has studied the effects of PPAR ligand, pioglitazone and
has the effect of inhibiting the growth of human leiomyoma as
well. These studies have the potential for translating into effective
treatment for this very distressing condition in women.
Stem Cell Research: Professor Ariff Bongso and his team are
working on:
1. Novel methods of hESC line derivation.
2. Germ cell differentiation from hESCs.
3. Somatic cell reprogramming using hESC cytoplasts and cell
fusion.
Endocrine: Professor Victor Goh and his team are continuing
with their work on aging among Singaporean men and women.
They are also collaborating with DMERI/DSO on various aspects
of military activities, including the impact of basic military training
on obese enlistees.
Sexual Dysfunction: Associate Professor PG Adaikan and
his team continue their work on sexual dysfunction. One of their
studies compared the cavernous muscle relaxant action of three
clinically available phosphodiesterase 5 inhibitors, sildenafil, tadalafil
and vardenafil and elucidated mechanism other than the classical
inhibition of NO-cGMP pathway which accounted only for 2030% of the cavernous muscle relaxant activity. These experimental
findings contribute to further understanding of the clinical
efficacy, pharmacokinetics and potential drug interactions with
alphaadrenoceptor blockers in the treatment of ED. A paper on
the preliminary findings is due to be published in European Journal
of Pharmacology.
Marine Biology and Endocrine Disruptors: Professor
Yong and his team had also made significant discoveries on the
endocrine disruptors in the seas of Singapore. The latest paper
describes how the endocrine disruptors have entered the food chain
and has contaminated the green mussel, Perna Viridis in Singapore’s
coastal waters.This study would be of great importance in ensuring
the health of the population and to discover the mechanism of how
these compounds are generated in the seas of Singapore.
GYNAECOLOGICAL ONCOLOGY
Biomarkers: Dr Mahesh, Dr Loganath, Dr Narasimhan and their
team have used a suite of genomic and proteomic techniques to
identify potential markers from sera and cystic fluid which could
facilitate early diagnosis of ovarian cancer.
Diagnostic Kits: The group is also involved in developing
diagnostic kits for testing the malignancy of ovarian tumours on
a real time basis. Data from their study carried out with Associate
Professor A Ilancheran have shown for the first time the presence
of a protein which has the potential to serve as a biomarker in
cystic fluid of patients presenting with epithelial ovarian cancer.
A patent application is pending based on this finding.
Haemostatic Markers: Dr Stephen Koh and his team showed
that haemostatic markers could be used in the prognostication of
this disease; their most recent work has been published.
Tissue Repository Network: The team is also in the
process of setting up a regional tissue repository network with the
department as the headquarters for the region.
4. Pharmacological applications of hESCs.
5. Comparative evaluation of human umbilical cord matrix stem
cells with hESCs.

Ophthalmology
INTRODUCTION
Research efforts in the Department of Ophthalmology remain integrated with the Singapore
Eye Research Institute (SERI), an NUS affiliated national research institute, as all NUS Dept of
Ophthalmology staff currently play leading roles in SERI, our national body for ophthalmic and
vision research. The Department’s research has also been augmented by cross-departmental
and cross-faculty collaborations, collaborative studies within eye departments from both
medical clusters, and many overseas institutions. This report focuses on specific research
achievements by NUS Department of Ophthalmology staff in 2005.
Department of Ophthalmology
Summary of research achievements in 2005
In 2005, 21 new research grants were secured by department staff.
There were 75 ongoing research projects which focus on major eye
diseases of specific regional relevance, including myopia, glaucoma,
ocular surface stem cells, ocular infections, retinal vascular
disorders, and cataract surgery. A total of 105 scientific papers in
peer reviewed international journals with a mean impact factor of
3.09 were published. This represents the highest publication output
in terms of quality and quantity from the department to date.
Project Description
In addition, our fulltime faculty won no less than 6 awards for
research, including 2 major Australian research awards (Assoc
Prof Wong TY), the Singapore National Academy of Science 2005
Young Scientist Award (Dr Leonard Ang) and a 2005 BMRC/

Planning for 1st ASIA-ARVO Meeting
Previously known as SERI-ARVO for meetings held in 2003 & 2005,
the name was changed to reflect ARVO commitment to partnering
with the many countries in Asia that have expanding eye research
programs. It will be held in locations throughout Asia to highlight
the important clinical and transnational aspects of vision and
ophthalmic research.
Singapore has been chosen to host the first Asia-ARVO Meeting,
in conjunction with SERI and the department. Following the
success of the last SERI-ARVO meeting in 2005, the Asia-ARVO
meeting will be held in Feb 2007, with over 500 abstracts and 900
participants expected.

INTRODUCTION
The Department of Orthopaedic Surgery is actively engaged in research that spans from basic science to translational
research and clinical applications of new technologies, and has on going research collaborations with local and overseas
institutions. Our research focus areas are in musculoskeletal tissue engineering, osteoporosis and fractures, and
orthopaedic bioengineering. The Department has been very much involved in the establishment of the Universitywide NUS Tissue Engineering Program (NUSTEP) and our tissue engineering team have won numerous research
awards at national and international level. In 2005, we secured 9 new research grants exceeding $1.4 million and
won eight awards for excellence in research. Our bioengineering team won the first prize in the Assistive Technology
Invention Competition organized by the Society for the Physically Disabled, as well as an Honourable Mention at
the 8th Wall Street Journal’s Asian Innovation Awards for an innovative low cost artificial leg. We were also awarded
the prestigious Albert Trillat Young Investigator’s Award for our study on the mechanical properties of the knee, and
the International Society for Clinical Densitometry (ISCD) Young Investigator’s Award for developing an innovative
protocol for measuring bone mineral density in the knee. A total of 54 scientific papers in peer reviewed international
journals were published, with 22 in Tier 1 and 2 journals.

DEPARTMENT
OF Paediatrics
INTRODUCTION
Research in the Department of Paediatrics is focused in three major areas: Human Genetics, Immunology and Allergy,
and Paediatric Oncology.
The Human Genetics Research Group aims to establish and develop genetic research and diagnostic facilities
in cardiovascular, endocrine (adrenal disease and obesity), neuromuscular, neurometabolic, haematology-oncology,
hepatobiliary (Alagille’s syndrome) and renal genetics, with regards to:
• Genetic epidemiology, including sequencing, mutation screening, and genotyping.
• Establishment of a cord blood bank resource representative of Singapore’s three major ethnic groups.
• Karyotyping and gene mapping by linkage analysis and molecular cytogenetics.
• Molecular diagnostics and gene therapy.
• Functional genomics and pharmacogenomics.
• Animal models of human development and disease.
Department of Paediatrics
The Neuromuscular and Neurogenetic Research Group
is currently focused on the following areas of translational
research:
• Molecular therapy for Duchenne and Becker muscular dystrophy.
The use of aminoglycosides in inducing mutation read-throughs
in Duchenne muscular dystrophy.
Development of antisense oligonucleotide therapy.
• Mutation screening for mitochondrial disorders.
Genotype and phenotype correlation of mitochondrial mutations
in mitochondrial encephalomyopathies.
Screening of mitochondrial mutations in children with nonsyndromic hearing loss.
Investigating the association between mitochondrial haplogroups
and sporadic Parkinson’s Disease in Singapore Chinese.
Mitochondrial sequence variations in the D-loop region of
patients with acute childhood leukemia.
• Studying genotype and phenotype correlations in rare
neurogenetic disorders.
Studying a rare mild phenotype of aromatic amino decarboxylase
deficiency in a family.
Investigating the cholesterol and cholesterol oxidation products
in Niemann Pick disease Type C patients and the npc1 mouse
model.
The BioMEMS consortium, a collaborative project between the
Genetics Group, Department of Biological Sciences, the Institute
of Microelectronics and three industrial partners, developed a viral
RNA micro extraction system, based on an earlier silicon chip
prototype. Being able to extract RNA from viruses would enable
detection of causal viruses in many human, animal and plant diseases.
With the attractive features of being portable, fully automated,
contamination-free and disposable, the detection of pathogenic
viruses at the point-of-care or point-of-need becomes a possibility.
The consortium was awarded the Commercialization of Technology
Fund by A*STAR to develop the viral RNA Micro Chip Extraction
System. The viral RNA micro extraction chip system, measures
2x2 cm, and is capable of yielding 720 copies of viral RNA from
a starting sample of 400µl blood spiked with a clinically relevant
level of 1000 viral particles. The project has also won the Professor
Jocelyn Hicks Best Poster Award at the 10th International Congress
of Pediatric Laboratory Medicine in September 2005.
The Immunology and Allergy Research Group has 2 major
laboratories:
092
The Pediatric Allergy Laboratory whose main areas are as
follows:
• Prevention and treatment of asthma and allergic diseases, where
the focus is on the optimization of DNA vaccines for allergic
diseases.
• Immunopathogenesis of asthma and allergic diseases, where the
focus is on establishing a murine model for allergic dermatitis
and asthma to study the underlying molecular mechanisms of
pathogenesis.
• Study of immunoregulatory proteins and their application in
treatment of allergic diseases.
• Further research and development on Blomia tropicalis mite
allergens with reduced allergeneicity and the generation of
hypoallergenic recombinant mite proteins as immunotherapeutic
reagents.
• Evaluation of the protective/therapeutic effects of recombinant
Lactobacillus expressing dust mite allergen Der p2 (L.casei /Der
p2) using a murine allergy model and to perform in vivo and in
vitro studies to elucidate the mechanisms of probiotics on the
induction of T regulatory and effector cells network in these
mice.
• The influence of environmental factors in the development of
childhood allergies:
(a) Clinical trial on the effects of probiotics on atopic disease in
babies at risk for atopy.
(b) Prospective study to compare the gut microbiota between
two populations, one with high prevalence of allergy
(Singapore) and one with low prevalence (Indonesia) in the
first two years of life.
The Pediatric Renal and Transplant Immunology Research
Laboratory focuses on the following:
• Immunopathogenesis of nephrotic syndrome, in particular minimal
change disease. The Group has developed an IL-13 transfection
rat model of minimal change-like nephropathy, which won the
Young Scientist Award at the World Congress of Nephrology,
2005.
• Immunogenetics of familial nephritis.
• Infections in solid organ transplantation.
The Pediatric Oncology Research Group has as its main focus
research in childhood leukemia. Their current research plans are as
follows:
Development of highly sensitive minimal residual disease markers
in childhood acute lymphoblastic leukemia. The Group currently
runs 2 multifaceted, multicentre trial involving childhood acute
lymphoblastic leukaemia and acute myeloid leukaemia (MA-SPORE
ALL 2003 and MA-SPORE AMC 2006 studies).

DEPARTMENT
OF Pathology
INTRODUCTION
As Pathology evolves into a complex and unique discipline recognized as both a basic biomedical science and a
clinical specialty, the Department of Pathology has kept pace with this evolution. We worked hard at upgrading
our core facilities, attracting top-level staff and accruing new equipment, in order to conduct quality research
in the study of mechanisms and in vitro manifestations of disease. To complement our internationally accredited
histology and immunohistochemistry laboratories, other core facilities such as laser capture microscopy,
molecular diagnostics and cytogenetics, electron microscopy and a departmental data system-computer network
were set up.
In 2005, the department achieved a vast increase in grant funding, maintained a sizeable publication record of
over 50 research papers in reputable international journals, more than half of which were basic research papers,
contributed a number of patents, and won a few national and international awards for excellence in research and
pioneering new frontiers in pathology.
Department of Pathology
Due to the encompassing nature of pathology, the research interests
and activities of our faculty cover a broad range that includes basic
science, translational research, and clinical research, deriving benefit
from synergistic opportunities related to intra-disciplinary, multidisciplinary, inter-disciplinary and trans-disciplinary interactions.
Many of our staff actively collaborate with fellow researchers
at the NUS Oncology Research Institute, with colleagues in the
Medical, Science and Engineering faculties, as well as with principal
investigators at the A-STAR research institutes at the Biopolis
research hub, with special focus on the biology, genetics and
immunology of cancer, and validation of new molecular markers
in cancer diagnostics and therapy. In recent years, the research in
tumour biology, the traditional strength of our department, has
evolved to include analysis of neoplasia at all levels of involvement:
molecular, nuclear, cell membrane, intracellular, and matrix; and the
identification and analysis of neoplastic events; and the application
of novel therapies.
Amongst our most notable contributions to Singapore’s biomedical
research initiatives is the extensive re-organisation of our vast tissue
repository reserves. Changes were made to enable researchers to
maximize the potential of using banked tissue resources such as
paraffin-archives for basic and translational research. To modernise
tissue banking practices, our TR faculty developed computerised
registry systems and established PI-centred cancer repositories
and associated bioinformatics systems.

RESEARCH REPORT 2005
DEPARTMENT OF
Pharmacology
INTRODUCTION
The Department is involved in both basic and clinical pharmacology research. The Department has organised
its research efforts into three main areas including Pharmacogenetics, Pharmacokinetics, Neuropharmacology,
Immunopharmacology and Cardiovascular Pharmacology. Members of the Department work together in these
general areas and collaborate with staff in other Departments and elsewhere in Singapore. The longer term strategic
aim is to increase the quality of research output and maintain a successful research focus which is competitive with
other academic institutions worldwide.
Specific research topics of interest in the current year include, (i) relationship of genetics to variability in
cardiovascular responses and in susceptibility to disease, (ii) optimization of anti-cancer (and other) drug therapy from
a pharmacokinetics perspective, (iii) gene and protein expression and involvement of local hormones and transmitters
in animal models of inflammation (asthma, pancreatitis, septic shock and acute respiratory distress syndrome),
(iv) neuroprotection, (v) role of pharmacological mediators in anxiety/depression/fear and the response to psychoactive
drugs, (vi) evaluation of novel derivatives of des-aspartate angiotensin I in cardiovascular and other disease states,
(vii) therapeutic uses of agents derived from natural products with particular reference to potential anti-cancer agents
and hypolipidaemics, (viii) physiological and pathophysiological significance of hyrdrogen sulphide in the cardiovascular
system, (ix) Understanding the molecular and structural machineries of neurotransmission and channelopathies as
therapeutic targets, (x) Regulation of glutamate receptors function and expression (xi) Structural proteomics of ion
channels, and (xii) crosstalk between dopamine and NMDA receptors in Parkinsonism.

DEPARTMENT OF
Psychological Medicine
INTRODUCTION
The strategic research initiatives of the Department include research on:
• Psychiatric Epidemiology and Gerontological Research.
• Early identification and treatment of psychiatric disorders, particularly schizophrenia and related psychoses.
• Psychological aspects of general medical and surgical conditions.
Our aim is to engage in collaborative research with local and overseas partners in both clinical and basic sciences,
leveraging on platform technologies like functional neuron-imaging and molecular/genetic research.
Research
Research in psychosis by the First Episode Schizophrenia (FES) Study Group has produced interesting new results of
dorsal lateral precortex activation in schizophrenia patients using fMRI.
The Gerontology Research Programme (GRP) is a flagship research initiative of the Department and provides a
systematic, coordinated programme of research activities on the health of the elderly Singaporeans that provide the
scientific information needed for formulating strategies of disease prevention and health promotion. The research has
produced the first nationally representative estimates of the prevalence of depression and dementia in the elderly for
policy information and planning. It has also published the first human evidence of the link between curry consumption
and better cognitive functioning in the elderly.
Following the SARS outbreak in 2003 the Department initiated research into the psychological reactions of healthcare
workers in Singapore and other SARS-affected countries.

RESEARCH REPORT 2005
National University
Medical Institutes (NUMI)
INTRODUCTION
Research interests in NUMI are:
• Oncology research (group leader: Prof Yoshiaki Ito).
• Cardiovascular research (Assoc Prof Eugene Sim).
• Reactive Oxygen Species (ROS) Biology and Apoptosis (group leader: Assoc Prof Shazib Pervaiz).
• Biology of pancreatic islet beta-cells and cell therapy for diabetes. Achieving functional insulin-producing cells
derived from embryonic progenitor cells (Assoc Prof Li Guodong).
• Neurodegenerative diseases (Dr Wong Boon Seng).
Oncology Research Programme
The Oncology Research Institute conducts research on 4 main types of cancers: Gastric, Breast, Colorectal,
Leukemia. These cancers are leading cancer deaths in Singapore as well as the Asia-Pacific region. In year 2005,
we have formed a small group which focus on bone cancers that is currently led by Visiting Associate Professor,
Assoc Prof Andre van Wijnen, who is from Department of Cell Biology, University of Massachusetts Medical School.
National University Medical Institutes (NUMI)
Cardiovascular Research Programme
We aim to restore the regional blood flow through therapeutic
angiogenesis and repopulate the scar tissue with myogenic cells for
treatment of myocardial infarction.
Specific achievements:
a. Human skeletal myoblasts were fused with host porcine
myocardium to form mosaic muscle fiber. The heterogeneous
muscle fiber expressed slow and fast isoforms of skeletal myosin
heavy chain. Thus, fusion between the donor myoblasts and the host
cardiomyocytes plays a significant role in the donor cell survival
which leads to the improved cardiac function. This further supported
by studies from studies of Reinecke et al. (2004) and Rubart et al.
(2004).
b. We have characterized skeletal myoblasts transduction with
angiogenic gene. The angiogenic gene carrying skeletal myoblasts
transplantation is safe and a more efficient stategy for cardiac repair.
No angioma and cancer were found. The significantly improved
heart function with regional blood flow suggested a novel approach
as concurrent angiogenesis and myogenesis.
ROS Biology and Apoptosis Programme
The ROS Biology program aims to identify mechanisms of redoxmediated pathways pertinent to cancer, and other disease states. To
that end the PIs are involved in a variety of extramurally funded
programs to enhance our understanding of these pathways for use
as biomarkers of disease or targets for novel drug design.
