Roger Tsien
Roger Yonchien Tsien (born February 1, 1952 in New York City , New York , † August 24, 2016 in Eugene , Oregon ) was an American cell biologist of Chinese descent and, together with Osamu Shimomura and Martin Chalfie, winner of the 2008 Nobel Prize in Chemistry .
life and work
Roger Tsien was the third son of the engineer Hsue-Chu Tsien and the nurse Yi-Ying Tsien, b. Li, born in New York City. He grew up in New Jersey Livingston . His eldest brother Richard Winyu Tsien is a neurobiologist at Stanford University . Aeronautical engineer Tsien Hsue-shen is his father's cousin.
As a student, Tsien carried out chemical experiments at home. In 1968 he won first prize from Westinghouse Science Talent Search for investigations into the binding of metals to thiocyanates . He studied chemistry and physics at Harvard University , where he made his bachelor's degree in 1972 . Then he went to the physiologist Richard Adrian to the Churchill College of the University of Cambridge , where he received his doctorate 1977th He was then a post-graduate student at Gonville and Caius College . In 1981 he moved to the Department of Physiology and Anatomy at the University of California, Berkeley as an assistant professor . From 1985 to 1987 he was an associate professor there and from 1987 to 1989 a full professor. Since 1989 he has been Professor of Pharmacology, Chemistry and Biochemistry at the University of California, San Diego and Researcher at the Howard Hughes Medical Institute . Visiting professorships led him to the Massachusetts Institute of Technology (MIT) in 1991 and to the University of Cambridge in 2003.
Tsien worked in the field of cell imaging biology. He created fluorescent dyes to make cellular calcium visible. To this end, he developed substances that can penetrate the cell membrane so that the movement of calcium could also be examined in living cells. He later improved the properties of the dye and used similar methods to detect sodium and cyclic adenosine monophosphate . To study the interaction of two molecules labeled with fluorescent dyes, he used fluorescence resonance energy transfer . Perhaps his best-known contribution was the provision of different variants of the green fluorescent protein (GFP) and their use. He later changed his research focus to the imaging and treatment of cancerous tumors. To do this, he developed a U-shaped peptide that - equipped with an imaging molecule or a drug - is specifically absorbed by the cancer cell. This is a so-called activatable cell-penetrating peptide (Engl. Cell penetrating peptides , CPP).
On July 30, 1982, he married Wendy M. Globe. Tsien died in August 2016 at the age of 64 while touring his motor tricycle in Eugene, Oregon, from a previously unpublished cause.
