Scientific Interest(s):

Dr. Jing Huang and her colleagues are using functional genomics, chemical genetics, molecular biology, biochemistry and bioinformatics to study Tor (target of rapamycin)-dependent and other signal transduction networks as well as the molecular basis of human diseases and/or conditions involving this pathway (including cancer, aging, diabetes, obesity and various brain defects and dysfunctions). Model systems in the lab include the yeast Saccharomyces cerevisiae and mammalian cells. Insights from these studies are used to design and discover novel molecular therapeutics.

A second major area of interest in Huang's lab is the screening of small molecule libraries (including natural product banks, combinatorial chemical libraries and drug collections) to identify probes for human and other proteomes. Probes with high specificity and affinity allow the researchers to conditionally knock out or activate the function (reactions and/or interactions) of any protein in the body. As such, these probes offer an ideal tool for dissecting the complex networks of molecular and physiological events in vivo. Furthermore, some probes may become important drugs, either for treating diseases involving protein dysfunction (e.g., cancer and Parkinson's Disease), for improving quality of life that is dependent on protein activity (e.g., longevity drugs, anti-depression drugs) or for fighting infectious diseases. Currently, the researchers are investigating the molecular mechanisms of two natural products with unique anti-cancer and cell biological profiles.

Huang's research in stem cell gene regulation (including the regulation of neural stem cell fate) is related to her interest in protein interaction network mapping.
