This chapter provides a detailed account of the life and work of Dr. Gregg L. Semenza, a renowned geneticist and Nobel laureate.
Born on July 12th, 1956 in Flushing, NY, Semenza developed an early interest in science, particularly genetics. He attended Harvard University, where he studied medical genetics and mapped genes on chromosome 21. He then received his PhD and MD at the University of Pennsylvania, where he mapped genes linked to beta-thalassemia, a genetic disorder.
Dr. Semenza completed his pediatrics residency at Duke University and his postdoctoral fellowship at Johns Hopkins University. It was here that he began his research on the EPO gene, which led to the discovery of the Hypoxia Inducible Factor 1 (HIF-1) and the body’s oxygen regulation mechanisms.
HIF-1 is a protein complex that binds to DNA segments depending on oxygen levels. When oxygen levels are low, HIF-1 binds to these segments, causing EPO…
