Study questions anti-cancer mechanisms of drug tested in clinical trials

But new research appearing the week of Jan. 13 in Proceedings of the National Academy of Sciences (PNAS) suggests that activation of AMPK may actually fuel cancer growth. Researchers from Cincinnati Children’s Hospital Medical Center who led the study also recommend that clinicians testing metformin for cancer treatment consider a careful re-evaluation of their clinical data. The researchers report on extensive laboratory tests that conclude metformin does stop cancer, although not by activating AMPK…

Classic signaling pathway holds key to prostate cancer progression

Although it is well established that the androgen receptor is important for prostate cancer progression, it is unclear what drives this process. Frigo and his team demonstrated in this study that androgens take control of the AMPK signaling cascade, a master regulator of metabolism, to increase prostate cancer cell growth. "The androgen signaling cascade is important for understanding early and late-stage prostate cancer progression. …
