Helen Hobbs

Helen Haskell Hobbs (born May 5, 1952 in Boston, Massachusetts) is an American medical researcher who is professor at the University of Texas Southwestern Medical Center, and a Howard Hughes Medical Institute Investigator, who won a 2016 Breakthrough Prize in Life Sciences and the 2018 Harrington Prize for Innovation in Medicine. She and Jonathan C. Cohen found that people with hypomorphic PCSK9 mutations had lower LDL-cholesterol levels and were almost immune to heart disease. This finding led to the development of a new class of cholesterol-lowering drugs that mimic the effects of the PCSK9 mutations. She and Cohen also identified the first genetic risk factor for fatty liver disease, a burgeoning health problem that can lead to cirrhosis and liver cancer. Their laboratory has shown that mutation in PNPLA3 causes accumulation of PNPLA3 on lipid droplets, which compromises the mobilization of triglycerides from liver cells. She sits on the Board of Directors at Pfizer. Provided by Wikipedia
