Research Interests:

Transcriptional regulation governs a broad spectrum of cellular activities: cell cycle progression, cell migration, apoptosis, or metabolism. We are interested in elucidating the molecular mechanisms underlying transcriptional regulation in response to physiological and pathological signals. Particularly, our research over the past decade has focused on CtBP, a transcriptional co-repressor, and has uncovered a unique function of this protein as a redox-sensor in transcription control. This function allows cells to couple the metabolic status with gene expression. Furthermore, we demonstrate that CtBP is subjected to post-translation modifications in response to cellular stress and, consequently, triggering apoptosis independent of p53. Both aspects of our research have important therapeutic implications in human diseases. The ultimate and long-term goal of my lab is to develop drugs against metabolic disorders and cancers based upon molecular details as revealed by basic research.
