Completing a decades old quest by biochemists and biophysicists scattered around the world, a multi-institutional team of researchers has discovered the structure of Complex II, a protein essential to the production of energy within cells.
Researchers at the University of California, San Francisco report that a novel osteoporosis prevention drug, called raloxifene, reduced the risk of invasive breast cancer in postmenopausal women with osteoporosis by 76 percent after forty months of treatment.
The first fully controlled two-year study of a new treatment for osteoporosis in postmenopausal women restored bone mass to its original level in nearly two thirds of the women participating in the trial, UC San Francisco scientists reported today.
Scientists at UC San Francisco, working with a new experimental model that turns yeast cells into little versions of human adrenal glands, have learned how the drug medroxyprogesterone acetate (MPA) inhibits one of the key enzymes necessary to produce steroid hormones.
Angina patients whose intense, often suffocating chest pains can not be reliably relieved by medication or invasive treatments can gain significant pain reduction from a little-used medical procedure that appears to increase heart blood supply, a new study has found.
Researchers at UC San Francisco have determined that telomerase - the enzyme brought to fame last year when scientists demonstrated that its insertion into normal cells extended the healthy life span of the cells indefinitely - can wield its power in an unexpected way.
Stanley B. Prusiner, MD, 55, today was named to receive the 1997 Nobel Prize in Physiology or Medicine for discovering and characterizing an entirely new class of proteins, called prions, which cause several rare and fatal neurodegenerative diseases.
