Research Interests

  • The role of histone modifiers in cancer
  • Rational combination therapy
  • Hypoxia signaling pathway and angiogenesis
  • miRNA function in cancer
  • Drug discovery

The genetic abnormalities that drive tumorigenesis are usually coupled with epigenetic alterations such as DNA methylation, aberrant histone modification and non-coding RNA expression, which may help oncogenic drivers accelerate cancer progression, metastasis and drug resistance. The next generation sequencing data have identified recurrent somatic mutations in multiple genes involving histone modifications and chromatin remodeling, providing direct evidence for the importance of epigenetic modifiers in cancer. In addition, deregulated gene expression of epigenetic modifiers is also commonly found in cancers. Our laboratory focuses on how epigenetics collaborate with oncogenic drivers during pathogenesis and development of specific small molecule inhibitors for precision medicine. Currently, we are using a variety of molecular, cellular, pharmacologic approaches and in vivo mouse models to dissect the functions of histone demethylases and other histone modifiers in pediatric cancers. We are also collaborating with Department of Chemical Biology and Therapeutics to screen histone demethylase inhibitors for cancer treatment.
