Kundan Sengupta obtained his BSc from St. Joseph’s College, Bangalore and MSc in Microbiology from Bangalore University. He undertook PhD in Molecular Biology from DBS, Tata Institute of Fundamental Research (TIFR) Mumbai followed by postdoctoral research at the Lab of Thomas Ried, National Cancer Institute, NIH, USA and was a research fellow at the lab of Pathology, NCI/NIH, USA. He joined IISER Pune in 2010 as Assistant Professor and was awarded the Wellcome-DBT India Alliance Intermediate Fellowship. He is currently Associate Professor in Biology at IISER Pune.

Research

Chromosome biology in development and disease

Role of nuclear Lamins in regulating genome organization and function: Genomics approaches such as Hi-C, further substantiate that the genome is non-randomly organized in the nucleus.  Ongoing studies in Dr. Kundan Sengupta's group are focused on the role of nuclear Lamins in regulating nuclear structure and function in cancer cells. These experiments revealed that while lamin depletion induced chromosomal aneuplodies in diploid colorectal cancer cells. Interestingly, the nuclear locations of these aneuploid chromosome territories were altered in the interphase nucleus. Furthermore, gene expression analyses of Lamin depleted cells also showed a significantly deregulated transcriptome. The group's current experiments focus on unraveling the underlying mechanisms by which Lamins and Lamin B Receptor (LBR) regulates chromosomal stability in colorectal and breast cancer cells.
