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 PutraOCW ASSOC. PROF. DR. CHEAH YOKE KQUEEN PutraOCW TITLE : Signature miRNAs expression, networks and interaction of various cancer (Name of project leader) : Assoc. Prof. Dr. Cheah Yoke Kqueen Department of Biomedical Science Faculty of Medicine and Health Sciences, Universiti Putra Malaysia. PutraOCW 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. PutraOCW Establishing the relationship of Genetic Signatures of Non-coding RNAs with Quantification value of micro Coronary Circulation as potential predictive Theranostic Markers for early preclinical asymptomatic high risk group for developing coronary artery disease.

PutraOCW 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 Theranostic and Predictive Markers for Coronary Artery Disease Quantitative PETCT imaging Molecular & Bioinformatics Prof. Dato Dr. Abdul Jalil Nordin AP Dr. Cheah Yoke Kqueen (UPM, PPDN) (UPM, MGI) Prediction & Prognostics AP Dr. Ahmad Fazli Abdul Aziz (UPM, Hosp Serdang, IJN) PutraOCW DR. NURAINUL HANA SHAMSUDDIN PutraOCW DNA methylation profiling to identify epigenetic dysregulation in emotionally distressed Asian adult with type 2 diabetes mellitus. (Dr Nurainul Hana Shamsuddin) Department of Family Medicine, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia. PutraOCW 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.

GEETA APPANNAH PutraOCW Randomised Control Trial on Childhood Obesity at Malaysian Primary Care Setting Dr Geeta Appannah, PhD (Cantab) Department of Nutrition and Dietetics Faculty of Medicine and Health Sciences Universiti Putra Malaysia PutraOCW Summary 1. More likely to obese as adults & at higher risk of CVD 5. No structured intervention studies with a long period of follow-up have been conducted in Malaysia 4. Primary care level is accessible to families across most social gradient & could provide continuous relationship 2. Effective early life prevention or intervention strategies are crucial Childhood obesity 3. Incorporating interdisciplinary approaches are found to be more substantial PutraOCW Western dietary patterns, genetic predisposition and obesity risk among Malaysian young people Dr Geeta Appannah, PhD (Cantab) Department of Nutrition and Dietetics Faculty of Medicine and Health Sciences Universiti Putra Malaysia 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 PutraOCW ASSOC.
