The Heritage of the Coris 214 I n d e x 221 Acknowledgments Regrett ably, many of the scientists who worked in the Cori laboratory have passed on and I have had to depend on writt en sources to reconstruct their lives and accomplishments. However, I am grateful to some of them who are still active and have great recollections of the laboratory. In this regard, I would like to thank Rollo and Janey Park, Joe Larner, Ernst Helmreich, Barbara (Bobbie) and David Brown, Luis Glaser, and Carl Frieden. I was also greatly helped by conversations with Maryda Colowick, Jennifer and Tilly Najjar, Tom Cori, Joel Hardman, and Murray Heimberg. No work of this magnitude can be accomplished without the assistance of many people. Th us I would particularly like to thank Jeremy Lewis and Hallie Stebbins my editors at Oxford University Press, and Maureen Cirnitski for superb copyediting. I am particularly grateful to Phil Skroska, Archivist, Visual and Graphic Archives at the Bernard Becker Medical Library at Washington University. Other important people were James Th weatt and Christopher Ryland of the Special Collections, Eskind Biomedical Library, Dominic Doyle of the Medical Art Group; and Kevin Davis of the General Counsel, all of Vanderbilt University. Others who provided help at vari- ous stages were Douglas Atkins of the National Library of Medicine, Louis Hue and Monique Van de Maelen at the de Duve Institute, Brussels. An important contribu- tor to the book was my Vanderbilt colleague Owen McGuinness, who provided much-needed word processing skills. Finally, but not least, I thank my wife Janet for her continuous support during the longer than expected birth of this book. ix This page intentionally left blank Introduction Th is is the story of Carl and Gerty Cori who established a laboratory at Washington University in St. Louis, Missouri, when Carl was appointed chair of Pharmacology in 1931 and chair of Biological Chemistry in 1946. Th e Cori labo- ratory remains unique in its contributions to biomedical science. Not only did both the Coris win the Nobel Prize, but also six other Nobel Laureates emerged from their laboratory, a record unmatched by any other U.S. institution. Th e dis- coveries of the Coris and their associates led to great advances in knowledge of how the body controls the level of glucose in the blood and how insulin and other hormones aff ect this. They defi ned the mechanisms by which the hormones epi- nephrine and glucagon control the breakdown of glycogen, which is the storage form of glucose in the body. Th ey studied the uptake of glucose from the gut and tracked what happened to it in the body. Th ey identifi ed many of the reactions involved in the processing of glucose and glycogen in the body and characterized many of the enzymes catalyzing these reactions. Th ey also studied how glucose was taken up by muscle and how hormones infl uenced this. us,Th their investiga- tions into carbohydrate metabolism were of great relevance to normal physiol- ogy and metabolic diseases such as diabetes. Th e Coris were both born in Prague in 1896 and met at the same medical school there. Aft er service in the Austrian Army during World War I, Carl fi nished his clini- cal studies and went to Vienna to marry Gerty. Because of Gerty’s Jewish heritage and the general conditions of life in Europe at that time, they decided to emigrate to the United States in 1922 where they took positions at a cancer research insti- tute in Buff alo. Th is is where they carried out their classic studies of the eff ects of adrenaline on glucose and glycogen metabolism that led to the formulation of the Cori cycle. Th e Cori cycle is a metabolic cycle whereby lactic acid released into the bloodstream by the breakdown of glycogen in muscle is reconverted to glycogen in the liver, and glucose produced by the breakdown of glycogen in the liver is returned to the muscle. xi xii Introduction In 1931, Carl was surprised to receive an off er from Washington University in St. Louis to become chairman of Pharmacology. When they took up their appoint- ments, the Coris resolved that real advances in their fi eld of research would come from the use of isolated tissues and the purifi cation and characterization of the enzymes involved in glucose and glycogen metabolism. Th is decision profoundly aff ected the course of their research, and their laboratory at Washington University was soon recognized to be at the forefront of biochemical research in the United States. Even before the Coris received the Nobel Prize in 1947, young scientists fl ocked to their laboratory from all over the United States and the world. Th e Coris had rather formidable personalities and were rigorous and demanding mentors. Th ey were intolerant of sloppy thinking and emphasized that any projects should be truly novel and any data should be reproducible and internally consistent. Th ey insisted that data should be analyzed quantitatively where applicable and that results should not be interpreted in terms of any preconceived notions, but with due consideration of alternative explanations. In short, their laboratory provided a superb training in the scientifi c method. Many of the scientists that trained in the Cori laboratory went on to make major discoveries and to win Nobel Prizes (Figure 1), and the careers of many of these are described in this book. Notable among them was Herman Kalckar, a Dane with an exceptionally creative mind who made wide-ranging discoveries and interacted with an astonishing number of Nobel Laureates. He made many important contri- butions to biochemistry. Th e Coris’ fi rst graduate student was Sidney Colowick, who had never taken a course in biochemistry and was qualifi ed by the U.S. gov- ernment as a shrimp inspector! He turned out to be a very quick learner and was described by Kalckar as having a brilliant analytical mind and being wise beyond his years. His experimental expertise was instrumental in the Coris’ discoveries in St. Louis. A major fi nding in which he played a key role was to defi ne the product of phosphorylase action on glycogen, which was, unexpectedly, glucose-1-phosphate. Colowick later achieved fame as coeditor of Methods in Enzymology , a series of vol- umes popularly known as the biochemist’s bible.
