 I'm Bill Brough and this is kidney cancer news. As reported by medical news today, Roswell Park Cancer Institute research on the most potent form of vitamin D offers new insights into approaches that may enhance the anti-tumor activity of this much-studied human hormone. After screening more than 55,000 compounds from a small library, scientists identified four shown to inhibit calcitriol. They then further examined the four components in prostate, bladder, and kidney cancer cell lines. According to one of the researchers, WeLow MD-PhD, we've known for years that vitamin D has the potential to help counteract and control cancer and sometimes has been shown to do so in the lab. But no one has been able to replicate those results in large clinical trials. It's exciting to be able to isolate some of the dynamics that might be helping tumors to evade the anti-cancer benefits of vitamin D. Reporting from Southwest Florida, I'm Bill Brough.
