Small, Smac-like molecule encourages death of cancer cells
...t. 3 issue of the journal Science, the researchers report on this new compound and how it behaves like the cellular protein Smac, a molecule that lifts barriers to cell death. Dr. Xiaodong Wang, professor of biochemistry and one of the authors of the Science paper, discovered Smac in 2000. "Every cell in ou...Rare deficit maps thinking circuitry
