Professional Interests


An attempt to search for cure of cancer has embarked on evaluating the therapeutic potential of bio-agents.  One such viable bio-particle is reovirus with an intrinsic preference to destroy oncogenic Kras activated transformed cell. More than 40% of human colorectal tumors are defective in K-Ras signaling cascade.  Presently my research aims in understanding the molecular mechanism of enhanced reovirus mediated cytotoxicity  in Kras compromised cellular environment. The insight has been further implemented in evaluating the therapeutic efficacy of reovirus in combination with chemotherapeutic drugs. This study is important especially for the group of patients with platinum refractory Kras mutated metastatic colorectal cancer (mCRC) where no FDA approved alternative therapy available.
