Dr. Alfred Gilman, a 1994 Nobel Prize-winning scientist and former dean of the University of Texas Southwestern Medical School, has died after a lengthy illness.
Gilman's death Wednesday was announced by UT Southwestern in Dallas. Gilman was 74.
Gilman shared the Nobel Prize in Physiology or Medicine with Dr. Martin Rodbell of the National Institute of Environmental Health Sciences for their discovery of G proteins. Such proteins help in the process of receiving signals from outside the cell and activating responses.
Gilman in 2012 resigned from the $3 billion Texas cancer research initiative after raising concerns about not enough scrutiny of proposals before funding was approved. Gilman had served as chief scientific officer of the Cancer Prevention and Research Institute of Texas, or CPRIT.
