Research Interests

Our main interest is in the application of Proteomics in the study of human diseases, especially in the discovery of novel biomarkers for their early detection. This is because the morbidity of many diseases is largely due to late diagnosis as a result of a lack of specific and sensitive biomarkers. In addition, the current thinking is that a panel of multiple biomarkers, rather than a single biomarker, will be needed for the diagnosis of a complex, multi-gene disease like cancer. Proteomics, being a high throughput method that can profile differentially expressed and/or modified proteins at a global scale, is considered to be well suited for this task. In fact the profiling of proteins from serum/plasma, saliva, urine, and gastric juice etc, to search for new biomarkers is restricted to Proteomics only as these biofluids do not have corresponding transcriptomes in which gene expression can be measured. To facilitate this work, we have established the Onco Proteomics Centre (OPC). The pipeline of Proteomics platform technologies developed include 2-D DIGE, 2-D LC, ICAT, iTRAQ, MALDI-TOF/TOF MS and bioinformatics (SPLASH). As a result, several biomarker discovery projects on gastrointestinal (GI) cancers are carried out in collaboration with clinicians.

Current projects include:
* Identification of prognostic biomarkers for hepatocellular carcinoma (HCC).
* Proteomics identification of proteins involved in colorectal cancer metastases.
* Discovery of gastric cancer biomarkers from gastric juice and sera.
* Proteomics analysis of gastric and colorectal cancer secretomes.
* Discovery of biomarkers for mitral valve prolapse.
* Proteome analysis of mesocarp tissues from oil palm fruit.
