Research Interests

Preserving the structural and functional integrity of genetic information is critical for all organisms. DNA is susceptible to various kinds of damage from exposure to endogenous (e.g., reactive oxygen species) and exogenous factors (e.g., radiation). All the organisms have evolved intricate mechanisms involving numerous DNA repair proteins to detect and repair multitude of DNA lesions. Mutations in genes encoding DNA repair proteins lead to genomic instability that is a hallmark of several debilitating diseases including cancer. Complex processes of DNA repair are regulated by interplay of protein-protein/DNA-protein interactions and are required for preserving genomic integrity and avoiding carcinogenesis. Identifying, characterizing and understanding biological significance of such interactions are essential steps for developing potential anti-cancer therapy.

 The Patidar lab is broadly interested in understanding the mammalian DNA damage and repair response with emphasis on delineating the molecular functions of novel DNA repair proteins, and seek translational research avenues to utilize these findings. The lab is also interested in developing anti-cancer drugs that create DNA damage and trigger cell death exclusively in cancer cells. Interdisciplinary approaches including protein biochemistry, cell and molecular biology, cancer biology, genomics, and proteomics are routinely employed to drive current research projects.
