Dr. Zheng’s research lab works on the forefront area of chemistry, biology and medicine. In the post-genomic research era, there has been a great shift in focus from simply collecting and archiving genomic data to dissecting and interpreting complex genomic/proteomic functions and networks. We are particularly interested in addressing critical problems and challenges in the rapidly evolving field of epigenetics that usually describes gene expression profile changes that are irrelevant to genomic sequence. Mounting data show that epigenetic processes play pivotal roles in transforming normal cells into malignant tumors and in various other pathologic conditions. Abnormality in epigenetic landscape presents characteristic biomarkers for disease diagnosis. The importance of epigenetic regulation in disease initiation and evolvement also signifies a new flow of challenges and opportunities to disease research and pharmaceutical discovery. Therefore, identifying key chromatin regulatory factors such as histone modifying enzymes and chromatin remodeling complexes, understanding their activity, specificity and functional roles, and inventing potent and selective drug compounds embody demanding needs in today’s biology and pharmaceutical research. Our lab is innovating and applying advanced chemical and biological strategies, tools and agents to elucidate functions of epigenetic enzymes in disease mechanism and meanwhile provide new diagnostic and therapeutic regimens. The lab adopts an interdisciplinary approach, spanning and integrating organic chemistry, medicinal chemistry, bioorganic chemistry, molecular biology, biochemistry, enzymology, cellular biology, biophysics and bioinformatics, and a wide range of techniques are employed.

Current active research areas include: (1) development of potent and selective epigenetic therapies, (2) design of chemical probes to understand protein acetylation and novel lysine acylation, and (3) mechanistic and functional study of protein arginine methylation.
