Background
Stroke is the third commonest cause of
death among Malaysians. The commonest
type is ischaemic stroke, usually
secondary to atherosclerotic disease
caused by uncontrolled hypertension.
Choline metabolism has a role in the
inflammation process in the pathogenesis
of the formation of atherosclerotic
plaques and subsequent plaque rupture.
Choline metabolism can be studied using
18F-choline PET/CT scan imaging.
Furthermore it can act as a surrogate
marker for non-invasively correlating
important clinical and proteomic factors
that contribute to impending stroke.
PutraOCW
• Several studies have been conducted to assess
the carotid arteries, which are the large vessels
supplying blood to the brain.
• However, in Malaysian population, it is the
thrombosis of small vessels in the brain that is
the major cause of stroke. Studies pertaining to
this are lacking.
• In addition, there is a need to explore possibility
of choline as a biomarker of inflammation, which
can be tagged with medication to deliver targeted
therapy to prevent plaque rupture.
PutraOCW
Objectives
• 1. To investigate choline metabolism in atherosclerotic
plaques and other secondary causes of abnormal glucose
metabolism, which are involved in the pathophysiology of
stroke
• 2. To identify associated clinical and genetic risk factors
involved in causing stroke, using 18F-choline PET/CT scan as
a non-invasive surrogate marker
• 3. To ultimately create a computer software tailored to
Asian population that helps stratify and prognosticate
stroke
• 4. To determine possibility of creating choline-tagged
medication that can deliver targeted therapy to prevent
atherosclerotic plaque rupture
PutraOCW
Methodology
• A randomized prospective study to assess risk
factors in Malaysians who had a recent stroke
using 18F-choline PET/CT imaging compared
to conventional Magnetic Resonance imaging
• To correlate the PET/CT findings with clinical,
biochemical and genetic parameters for the
risk stratification and prognostication of stroke

TITLE : Signature miRNAs

interaction of various cancer

Cancer is a complex disease that contribute to the major cause of mortality and
morbidity. MicroRNAs (miRNAs) are critical regulators of gene expression and
influence numerous cancer-relevant processes such as proliferation, cell cycle control,
apoptosis, differentiation, migration and metabolism. This study aims to profile and
characterize miRNA expression and regulation in various common cancers such as
lung, breast, head and neck, colorectal and prostate. There is lack of integrated
information on a specific miRNA expression, regulation among these cancers and also
naturally occurring cancer in animals.

Project description
•
Ischemic Heart Disease (IHD) is one of the leading causes in mortality. Non-coding
RNAs including microRNAs (miRNAs) and long non-coding RNA (lncRNAs) had been
reported associated with (IHD) and potentially useful as theranostic markers. Our
research team unravel 20 differentially expressed miRNA and 10 novel miRNAs
associated with IHD patients. So far, no study conducted for the association of the
Positron Emission Tomography (PET) for quantifying myocardial blood flow (MBF)
in the coronary artery microcirculation with non-coding RNAs

This study aims to determine psychological factors effect on DNA methylation of selected genes involved in
chronic immune/inflammatory processes and inflammation-related endothelial dysfunction in the Asian adults
with T2DM. Such epigenetic dysregulation may represent biological pathways that mediate the effects of
psychological factors on diabetes-related complications. The results of this study is expected to give a strong
motivation for psychosocial support initiatives Asian adults with T2DM.

Western dietary patterns, genetic
predisposition and obesity risk among
Malaysian young people
Dr Geeta Appannah, PhD (Cantab)

PutraOCW
Summary
Greater adherence to the a specific dietary pattern i.e. Western, characterised by a high intake of red and
processed meats, refined grains, high-fat milk, sugar sweetened beverages and confectionery was associated with
increased risk of obesity in young people
Obesity is a product of the interplay between genetic and lifestyle factors
It is possible that high intakes of Westernised diets are more likely to increase the risk of obesity among
those with higher genetic susceptibility to this disease
Such evidence of gene-diet/lifestyle interactions on the development of obesity is sparse, particularly in
young people
Identification of gene-diet/lifestyle interactions early in life will generate a better understanding of the
causal pathways that lead to obesity
To examine the potential interactions between the genetic predisposition to obesity defined by the wellestablished genetic variants and empirically derived dietary patterns in relation to obesity risk in a large
observational study of Malaysian children
