David TAN

My primary clinical and research interests are in gynaecological (ovarian, cervical, endometrial) cancer and drug development.  My work is focused on the development of biomarkers and novel anti-cancer therapeutic agents.

My research is focused on the development of biomarkers and novel therapeutic agents in gynaecological cancers.  Gynaecological cancers represent a highly heterogenous group of diseases, with each tumour subtype harbouring specific molecular aberrations and presenting its own unique clinical challenges.  Understanding the genetic and tumour microenvironmental factors that drive these cancers will be crucial for the development of new therapeutic strategies.  By elucidating the genomic/ molecular profiles of gynaecological cancers using a variety of high-throughput analytic platforms, our aim is to identify aberrant molecular pathways that may potentially be exploited for therapeutic development.   For example, Poly (ADP-ribose) polymerase (PARP) is a family of proteins involved in a number of cellular processes involving mainly DNA repair, and PARP inhibitors and DNA-damaging agents have been shown to be particularly effective in the treatment of ovarian cancers with defects in the homolgous recombination DNA repair pathway. We are currently developing biomarkers that will facilitate the identification of patients whose tumours harbour deficiencies in these DNA repair pathways.
