Research Interests:

  • Function and regulation of histone deacetylases (HDACs) in lung cancer and chemosensitivity
  • Identification of novel enzymatic activities in HDACs
  • Assessment of HDAC inhibitors in human cancer cell lines and animal models
  • Examination of the post-translational modifications in DNA repair proteins

Research Description:
Dr. Zhang's lab has a long-standing interest in the role of histone deacetylases (HDACs) in lung cancer and chemoresistance.  Her lab was among the first to reveal that HDAC6 is associated with cisplatin sensitivity in lung and ovarian cancer cell lines. Her team has also identified the extracellular signal-regulated kinase 1/2   (ERK1/2) as a modulator for HDAC6's enzymatic activity. Most significantly, her group discovered a novel ubiquitin E3 ligase activity within HDAC6 and linked HDAC6 to DNA mismatch repair and DNA damage response. Currently, there are three ongoing projects in her lab: 1) To explore the mechanisms by which HDAC6 regulates lung cancer sensitivity to tyrosine kinase inhibitors (TKIs); 2) To elucidate how ubiquitin-specific peptidase 10 (USP10) governs cisplatin sensitivity via HDAC6; 3) To explore how HDAC6 regulates ERK1 function via deacetylation.
