Research Interests:

microRNA mediated gene regulation in cancer

Our laboratory is basically interested in understanding the microRNA (miRNA) mediated gene regulatory networks in sarcoma and other cancer types. We explore miRNA-mRNA associations that have potential role in tumor onset, progression, and aggressiveness through miRNA and mRNA profiling as well as functional characterization of candidate miRNAs using in vitro and in vivo approaches. This will aid in the identification and development of novel miRNA-based biomarkers and targets for therapy. Our laboratory also is interested in engineering miRNA dysregulation in vivo and developing assays for screening small molecule inhibitors that can potentially modulate miRNA expression. The specific areas of research includes

  1. Understanding the role of miRNAs in malignant transformation process.
  2. Characterization of miRNA regulatory networks using comparative oncology of human and canine osteosarcoma.
  3. Molecular mechanisms of microRNA expression and regulations.
