My contributions to the identification of Gene Fusions in Cancer

My primary research interest is to characterize genomic rearrangements in cancer and understand their molecular consequences in a translational research perspective.

Identification of gene fusions at breakpoint junctions on chromosomes is an active area of research since the discovery of BCR-ABL gene fusion from t(9;22) translocation in chronic myeloid leukemia.
  • Gene fusions are important mutations identified in a variety of cancer.
  • Common in hematological malignancies (leukemia and lymphoma), sarcoma and some solid cancer including prostate cancer and lung cancer.
  • Difficult to identify in solid cancer by conventional cytogenetic methods
  • Inter and intra chromosomal rearrangements cause gene fusions.
  • Intra chromosomal, unbalanced rearrangements are common in solid cancers.
  • Molecualr consequences of rearrangement result in activation of an oncogene or formation of gene fusion.
  • During my research on cancer since 1996 - 2010, I was involved in the identification and characterization of the following genomic rearrangements and associated gene fusions in different types of cancer.
