Alfred Gilman, 74, a scientist who won a Nobel Prize for his breakthrough research into the inner workings of cells, and the former dean of the University of Texas Southwestern Medical School in Dallas, has died. A school spokesman said Thursday that Dr. Gilman's death was reported by his family. He had been fighting pancreatic cancer.
Dr. Gilman shared a 1994 Nobel Prize in Physiology or Medicine with Martin Rodbell of the National Institute of Environmental Health Sciences for their discovery of G proteins. The proteins help in the process of receiving signals from outside the cell and activating responses. - AP
