Our team at CSI is part of the multi-institutional Cancer Epigenome research laboratory (http://tbtlab.org/), which focuses on integrated epigenomic and genomic profiling in Asian cancers using enabling technologies such as ChIP-Seq, RNA-seq, Whole-genome and DNA methylation sequencing. The data is then correlated with clinicopathological information including how patients respond to certain drugs. The group always emphasizes on collaboration (both local and international) which is key to scientific breakthroughs.

We have characterised the genomic landscapes of several tumour types that are more prevalent in the Asian population, such as upper urinary tract urothelial cancer in Taiwan, cholangiocarcinoma in the north-east of Thailand, NK/T-cell lymphoma, and fibroepithelial tumours of the breast. As part of the Cancer Epigenome research laboratory , our team at CSI is focused on protein structural biology and drug discovery. Our research goals are:

i. To identify the genetic features of various types of tumors, including mutational profiles and gene signatures, by next generation sequencing approaches.
ii. To investigate the functional implications and mechanisms of such genetic alterations by biochemical assays and structural studies.
iii. To discover potential therapeutics based on our mechanistic understanding of the tumor-associated mutant proteins.

We emphasize on team science and collaborate widely with experts from within and outside of the country. We work closely with clinicians, including oncologists, surgeons and pathologists, to understand the clinical implications of our findings, particularly how the mutations in these genes are correlated with various clinical-pathological parameters (tumour grade, stage, survival, and drug response). We also collaborate with pharmaceutical and biotechnology companies to further investigate drug targets and mechanisms. As a dynamic team, we strive towards a common goal of developing personalized medicine for cancers through our combined and continuous effort in making new discoveries and translating them into novel diagnostics and therapeutics.
