Gerty Cori

Gerty Cori was a pioneering biochemist who made fundamental discoveries in carbohydrate metabolism. She shared the Nobel Prize in Physiology or Medicine in 1947 with her husband Carl Ferdinand Cori and Bernardo Houssay, becoming the first American woman to win a Nobel Prize in science. Her work elucidated the Cori cycle and the enzymatic breakdown of glycogen, laying the groundwork for understanding endocrine and metabolic diseases.

Early life and education

Gerty Theresa Radnitz was born in 1896 into a Jewish family in Prague, then part of the Austro-Hungarian Empire. She was educated at home before attending a lyceum for girls, and despite barriers for women in higher education, she gained admission to the German University in Prague to study medicine. There, she met fellow medical student Carl Ferdinand Cori, and they bonded over a shared passion for scientific research. Both graduated with medical degrees in 1920, married shortly after, and began their collaborative scientific careers in Vienna and Trieste before immigrating to the United States in 1922 to escape the deteriorating political climate in post-war Europe.

Research and career

Upon arriving in the United States, the Coris faced professional challenges, with many institutions reluctant to hire a married scientific couple. Gerty Cori initially took a position as a pathologist at the State Institute for the Study of Malignant Diseases in Buffalo, New York, while her husband worked at the same institute. In 1931, they both moved to the Washington University in St. Louis School of Medicine, though Gerty was initially offered a low-ranking research position despite her expertise. At Washington University in St. Louis, their collaborative work flourished in the Department of Pharmacology, and later Biochemistry, where they meticulously investigated the metabolism of glucose and glycogen. Their laboratory became a world-renowned center for biochemical research, training future Nobel laureates like Arthur Kornberg and influencing the field of molecular biology.

Nobel Prize and scientific contributions

The Coris' most celebrated achievement was the detailed description of the catalytic conversion of glycogen, known as the Cori cycle. This cycle explains how lactic acid produced in muscles during exercise is transported to the liver, converted back to glucose, and then recirculated to muscles. In 1947, they were awarded the Nobel Prize in Physiology or Medicine for this discovery. Furthermore, their team, including collaborator Gerty Cori as a driving intellectual force, identified and isolated the enzyme glycogen phosphorylase, the first enzyme shown to be regulated by phosphorylation and allosteric effects. This work provided a foundational model for understanding enzyme regulation and signal transduction pathways critical in fields like endocrinology and cancer research.

Later life and legacy

Despite her Nobel Prize, Gerty Cori continued to face gender-based professional obstacles, not being promoted to full professor at Washington University in St. Louis until 1947, the same year she won the Nobel. She maintained an active research program, investigating glycogen storage diseases and making significant contributions to the understanding of these inherited metabolic disorders. She served on committees for the National Science Foundation and the American Cancer Society. Gerty Cori died in 1957 from myelofibrosis, a bone marrow disease. Her legacy endures through the numerous scientists she mentored, the fundamental biochemical pathways that bear her name, and her role as a trailblazer for women in biochemistry and medicine.

Awards and honors

In addition to the Nobel Prize in Physiology or Medicine, Gerty Cori received numerous accolades. She was awarded the Garvan–Olin Medal by the American Chemical Society in 1948. She was elected a member of the American Academy of Arts and Sciences and the National Academy of Sciences, becoming only the fourth woman elected to the latter. She received honorary degrees from institutions including Boston University, Smith College, and Yale University. The American Society for Biochemistry and Molecular Biology awards the annual Gerty Cori Award in her honor, and a crater on Venus is named Cori after her.
