Biography

Paul S. Mischel (born July 13, 1962) is an American physician-scientist whose laboratory has made pioneering discoveries in the pathogenesis of human cancer (Paul Mischel lab website: https://paulmischellab.org/). He is currently a Distinguished Professor at the University of California San Diego, and a member of the Ludwig Institute for Cancer Research.Mischel was elected into the American Society for Clinical Investigation (ASCI), serving as ASCI president in 2010/11. He was inducted into the American Association of Physicians, and was elected as a fellow of the American Association for the Advancement of Science

Career

Mischel was born on July 13, 1962. After losing his father to cancer, he became committed to a career in cancer research. He attended the University of Pennsylvania and received his M.D. from Cornell University Medical College in 1991, graduating Alpha Omega Alpha. Mischel completed residency training in Anatomic Pathology and Neuropathology at UCLA, followed by post-doctoral research training with Louis Reichardt at HHMI-UCSF. Mischel joined the faculty of UCLA in 1998. In August 2012, he was recruited to the Ludwig Institute for Cancer Research, San Diego and UCSD.

Research

Mischel’s work bridges cancer genetics, signal transduction and cellular metabolism in the pathogenesis of human cancer.

Extrachromosomal oncogene amplification

Mischel found that tumors can dynamically change in response to changing environments at a rate that cannot be explained by classical genetics. Prior to 2017, extrachromosomal DNA was thought to be a rare, but interesting event in cancer (1.4% of tumors), of unclear biological significance. Mischel and colleagues integrated whole genome sequencing, cytogenetics and structural modeling to accurately and globally quantify extrachromosomal oncogene amplification, measure its diversity, map its contents, and study its biochemical regulation. They demonstrated widespread extrachromosomal oncogene amplification across many cancer types, showed that it potently drives tumor evolution and drug resistance, and identified specific signaling, biochemical and metabolic mechanisms that control its copy number and activity in response to changing environmental conditions. This ground-breaking work challenges existing chromosomal maps of cancer, provides new insights into the mechanisms controlling the level, location and activity of amplified oncogenes, and yields new paradigms in the genotype-environment interactions that promote cancer progression and drug resistance.

Metabolic co-dependency pathways in cancer

Integrating mechanistic studies with analyses of tumor tissue from patients treated in clinical trials, Mischel and colleagues discovered signaling, transcriptional, and metabolic co-dependencies that are downstream consequences of oncogene amplification, including alterations in glucose and lipid metabolism that drive tumor growth, progression and drug resistance. These studies, focused primarily on the highly lethal brain cancer, glioblastoma, resulted in new understandings of the fundamental metabolic processes by which oncogene amplification drives cancer progression and drug resistance, demonstrating a central role for EGFR and its downstream effector mTORC2, in cancer pathogenesis through metabolic reprogramming.
