Document:
Dr. Vijay Kumar obtained his PhD from All India Institute of Medical Sciences, New Delhi and received post-doctoral training at the University of Louis Pasteur, France. He was involved in the cloning of human estrogen receptor gene, solving its domain structure and establishing how hormone induces allosteric change for its DNA binding. Further, he showed the importance of receptor variant analysis in the management of breast and prostate cancer patients. Thereafter, he had an illustrious career as a staff scientist at the International Centre for Genetic Engineering and Biotechnology, New Delhi where he investigated the role of X protein of hepatitis B virus (HBx) in abetting oncogenic activities leading to hepatocellular carcinoma (HCC). His work has shown that HBx can deregulate cell cycle by modulating CDK2 activity and mitogenic signaling, inducing ribosome biogenesis and even engaging cellular DNA replicative machinery - all working in tandem towards cell transformation. He developed India’s first HBV-related transgenic oncomouse model of HCC which has helped in understand disease biology as well as screening anticancer agents. He has more than 110 International publications to his credit, including Nature, Cell, EMBO Journal and Journal of Biological Chemistry with a cumulative 10,000 plus citations. Dr. Kumar is a fellow of the National Academy of Medical Sciences as well as elected fellow of National Academy of Sciences and National Academy of Agricultural Sciences. He is also a recipient of Shanti Swarup Bhatnagar Prize in Medical Sciences for his scientific contributions in the field of Hepatitis B Virology. His current research interests include development of new antivirals for hepatitis B virus and epigenetic regulation of viral cccDNA for therapeutic targeting. He is an active member in many Institutional committees and presently also serving as Dean (Academic).
