OverviewAI-generated summary
Ratan Sadhukhan's research focuses on the molecular mechanisms underlying DNA repair, cell survival, and the development of therapeutic strategies for cancer and radiation-induced injuries. His work investigates the roles of key proteins such as PARP1 and SIRT2 in maintaining genomic stability and mitigating treatment side effects. Sadhukhan has studied how dietary factors, like methionine deficiency, can impact genetic instability in immune cells. He has also explored the potential of compounds like nicotinamide riboside to alleviate chemotherapy-induced neuropathy through specific protein activation. His publications indicate a focus on understanding how these molecular pathways influence tumor response to targeted therapies, such as PARP1 inhibitors, and how they can be modulated to protect normal tissues during cancer treatment, particularly in the context of oral mucositis.
