Research Interests
Genome maintenance is an essential cellular task. Compromised genomic integrity results in several debilitating diseases such as neurodegenerative disorders, autoimmune diseases, and cancer. Genomic integrity is constantly challenged due to the intrinsic susceptibility of DNA to various kinds of damage from exposure to various endogenous (e.g., reactive oxygen species, R-loops, replication stress) and exogenous (radiation, chemical mutagens) factors. The intricate task of genome maintenance is promoted by myriads of proteins involved in preventing, recognizing and resolving DNA damage.
The Patidar lab is interested in understanding the mammalian DNA damage and repair response with emphasis on delineating the molecular functions of novel DNA repair proteins and seeking translational research avenues. We are 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 & molecular biology, cancer biology, genomics, proteomics and RNAi are routinely employed to drive on-going research.
