Research Interests

Protein lysine acetyltransferases (KATs) catalyze the acetyl attachment to lysine side chains of protein substrates that include histones and many other cellular proteins. Deacetylases (HDACs) catalyze the reverse reaction to remove the attached acetyl group. Acetylation of protein substrates impacts their stability and functions in a variety of cellular pathways such as gene transcription, intracellular trafficking and metabolisms. Both KATs and HDACs are implicated in human diseases and represent rational therapeutic targets. The research in the Liao laboratory focuses on understanding cell-biological functions of these enzymes in virology, epigenetics and cancer biology, as well as on discovery, characterization, and optimization of novel small-molecule inhibitors of these enzymes for cancer therapy. In collaboration with the high-throughput screen facilities at Scripps Florida at Jupiter and the Sanford Burnham Medical Research Institute at Lake Nona, we aim at identifying novel lead KAT and HDAC inhibitors. We use in vitro biochemical as well as cell-based assays to validate their activities. We also collaborate with medicinal chemists to optimize the lead compounds to improve the target potency and specificity as well as drug-like properties of the lead compounds. We use mouse tumor models to determine in vivo anticancer efficacy of the small-molecule inhibitors. Ultimately, our optimized KAT and HDAC inhibitors may lead to novel therapy for treating cancer patients and other human diseases.
