Warfarin, a widely used blood thinner, appears to have potent anti-cancer properties, according to a study. "Our findings suggest that warfarin, which is already approved by the FDA, could be repurposed to treat a variety of cancers, including pancreatic cancer," says Wei Gu, Ph.D. Cancer researchers are excited by the idea of harnessing ferroptosis—so-named because it requires iron to work—to kill cancer cells. Drugs that induce ferroptosis may be particularly useful for cancers that elude current treatments. Gu, Stockwell, and their colleagues performed genetic screens on human melanoma cells to identify genes that contribute to ferroptosis. As expected, the screens...
