Michael B. Kastan, MD, PhD | Class of 2017

A leader in the areas of molecular biology, signal transduction, and DNA damage and repair, Dr. Kastan spearheaded pivotal investigations that helped to define the networks of signaling pathways that enable cells to deal with exposures to DNA-damaging agents and other cellular stresses. His discoveries have stimulated and continue to be utilized for the development of experimental cancer therapeutics designed to modulate the activity of proteins involved in these processes.

Dr. Kastan’s research has uncovered molecular mechanisms that govern responses to both chemotherapy and radiation therapy and illustrated cross talk between cell signaling, metabolism, and survival. Dr. Kastan’s laboratory made the seminal observation that the induction of p53 protein by genotoxic damage blocks entry into S phase, providing the first insights into the biological function of this critical tumor suppressor and establishing the presence of cell cycle checkpoints in mammalian cells. He subsequently showed that ATM is a protein kinase capable of directly phosphorylating p53 and is required for optimal p53 activation in response to ionizing radiation. His discoveries established the initial biochemical steps in what is now called the “DNA damage response” (DDR) pathway and identified a number of critical ATM substrates in the DDR, many of which are encoded by human cancer susceptibility genes. This included discovering that ATM autophosphorylation occurs at the onset of this signaling pathway, a modification that has proven to be an invaluable marker of cellular stress.

Dr. Kastan’s continued work involving ATM has pinpointed additional roles for the protein in modulating mitochondrial function, insulin signaling, and cellular metabolism. His work has also been used to inform drug development efforts pertaining to the establishment of radioprotective agents for normal tissues and radiosensitizers for various tumor types.
