A major interest of our lab is to determine how tyrosine phosphorylation regulates epigenetic processes that affect cellular homeostasis, immune impairment and cancer cell survival. We employ multiple kinases & phosphatases:

ACK1 (TNK2) : An oncogene with epigenetic activity in prostate, breast & lung cancers

WEE1 : A novel epigenetic modulator & its significance in various malignancies

Major findings of our lab include:

  • Discovered 3 new epigenetic events:
    • Y88-Phosphorylation of histone H4
    • Y37-Phosphorylation of histone H2B
    • Y99-Phosphorylation of histone H3
  • Identified a novel lncRNA, NXTAR that regulated expression of AR
  • Developed a new class of a small molecule inhibitor for ACK1, (R)-9b
  • Identified a novel WEE1 epigenetic inhibitor
  • Identified a novel AKT Tyr176-phosphorylation that causes AKT activation
  • Identified novel AR Lys609-acetylation
  • Identified a new class of KDM6 inhibitor

These studies led to establishment of TechnoGenesys, Inc., a startup focusing on new cancer drugs.

Current Projects in Lab

  • Epigenetic signaling in dampening immune cells response to tumors
  • Characterization of novel WEE1 and KDM6 inhibitors
  • LncRNA as Androgen receptor regulator and therapeutic strategy
