Glucagon is a peptide hormone, produced by alpha cells of the pancreas. It raises the concentration of glucose and fatty acids in the bloodstream and is considered to be the main catabolic hormone of the body. It is also used as a medication to treat a number of health conditions. Its effect is opposite to that of insulin, which lowers extracellular glucose. It is produced from proglucagon, encoded by the GCG gene.
Lasker–DeBakey Clinical Medical Research Award is one of four annual awards presented by the Lasker Foundation. The Lasker–DeBakey award is given to honor outstanding work for the understanding, diagnosis, prevention, treatment, and cure of disease. This award was renamed in 2008 in honor of Michael E. DeBakey. It was previously known as the Albert Lasker Award for Clinical Medical Research.
Glucagon-like peptide-1 (GLP-1) is a 30- or 31-amino-acid-long peptide hormone deriving from tissue-specific posttranslational processing of the proglucagon peptide. It is produced and secreted by intestinal enteroendocrine L-cells and certain neurons within the nucleus of the solitary tract in the brainstem upon food consumption. The initial product GLP-1 (1–37) is susceptible to amidation and proteolytic cleavage, which gives rise to the two truncated and equipotent biologically active forms, GLP-1 (7–36) amide and GLP-1 (7–37). Active GLP-1 protein secondary structure includes two α-helices from amino acid position 13–20 and 24–35 separated by a linker region.
Jeffrey M. Friedman is a molecular geneticist at New York City's Rockefeller University and an Investigator of the Howard Hughes Medical Institute. His discovery of the hormone leptin and its role in regulating body weight has had a major role in the area of human obesity. Friedman is a physician scientist studying the genetic mechanisms that regulate body weight. His research on various aspects of obesity received national attention in late 1994, when it was announced that he and his colleagues had isolated the mouse ob gene and its human homologue. They subsequently found that injections of the encoded protein, leptin, decreases body weight of mice by reducing food intake and increasing energy expenditure. Current research is aimed at understanding the genetic basis of obesity in human and the mechanisms by which leptin transmits its weight-reducing signal.
The glucagon-like peptide-1 receptor (GLP1R) is a G protein-coupled receptor (GPCR) found on beta cells of the pancreas and on neurons of the brain. It is involved in the control of blood sugar level by enhancing insulin secretion. In humans it is synthesised by the gene GLP1R, which is present on chromosome 6. It is a member of the glucagon receptor family of GPCRs. GLP1R is composed of two domains, one extracellular (ECD) that binds the C-terminal helix of GLP-1, and one transmembrane (TMD) domain that binds the N-terminal region of GLP-1. In the TMD domain there is a fulcrum of polar residues that regulates the biased signaling of the receptor while the transmembrane helical boundaries and extracellular surface are a trigger for biased agonism.
Arthur L. Horwich is an American biologist and Sterling Professor of Genetics and Pediatrics at the Yale School of Medicine. Horwich has also been a Howard Hughes Medical Institute investigator since 1990. His research into protein folding uncovered the action of chaperonins, protein complexes that assist the folding of other proteins; Horwich first published this work in 1989.
Glucagon-like peptide-1 (GLP-1) receptor agonists, also known as GLP-1 analogs, GLP-1DAs, or incretin mimetics, are a class of anorectic drugs that reduce blood sugar and energy intake by activating the GLP-1 receptor. They mimic the actions of the endogenous incretin hormone GLP-1, which is released by the gut after eating.
Charles L. Sawyers is a Howard Hughes Medical Institute (HHMI) investigator who holds the Marie-Josée and Henry R. Kravis Chair of the Human Oncology and Pathogenesis Program (HOPP) at Memorial Sloan Kettering Cancer Center (MSK). HOPP is a program created in 2006 that comprises researchers from many disciplines to bridge clinical and laboratory discoveries.
Brian J. Druker, M.D. is a physician-scientist and JELD-WEN Chair of Leukemia Research at Oregon Health & Science University (OHSU) in Portland, Oregon. He previously served as chief executive officer and director of OHSU's Knight Cancer Institute, as well as Associate Dean for Oncology in the OHSU School of Medicine.
Douglas L. Coleman was a scientist and professor emeritus at the Jackson Laboratory, in Bar Harbor, Maine. His work predicted that there exists a hormone that can cause mice to feel full, and that a mutation in the gene encoding this hormone can lead to obesity. The gene and corresponding hormone were discovered about 20 years later by Jeffrey M. Friedman, Rudolph Leibel, and their research teams at Rockefeller University, which Friedman named leptin.
James Patrick Allison is an American immunologist and Nobel laureate who holds the position of professor and chair of immunology and executive director of immunotherapy platform at the MD Anderson Cancer Center in Houston, Texas.

Daniel Joshua Drucker is a Canadian endocrinologist. A Fellow of the Royal Society, he is a professor of medicine at the Lunenfeld-Tanenbaum Research Institute, Mount Sinai Hospital, Toronto. He is known for his research into intestinal hormones and their use in the treatment of diabetes, obesity, and other metabolic diseases, as well as intestinal failure.
Semaglutide is an anti-diabetic medication used for the treatment of type 2 diabetes and an anti-obesity medication used for long-term weight management. It is a peptide similar to the hormone glucagon-like peptide-1 (GLP-1), modified with a side chain. It can be administered by subcutaneous injection or taken orally. It is sold by Novo Nordisk under the brand names Ozempic and Rybelsus for diabetes, and under the brand name Wegovy for weight management and weight loss.
Gregg Leonard Semenza is an American pediatrician and Professor of Genetic Medicine at the Johns Hopkins School of Medicine. He serves as the director of the vascular program at the Institute for Cell Engineering. He is a 2016 recipient of the Albert Lasker Award for Basic Medical Research. He is known for his discovery of HIF-1, which allows cancer cells to adapt to oxygen-poor environments. He shared the 2019 Nobel Prize in Physiology or Medicine for "discoveries of how cells sense and adapt to oxygen availability" with William Kaelin Jr. and Peter J. Ratcliffe. Semenza has had thirteen research papers retracted due to falsified data.
William G. Kaelin Jr. is an American Nobel laureate physician-scientist. He is a professor of medicine at Harvard University and the Dana–Farber Cancer Institute.
