This is probably a repost, but cool anyways.

CSHL Professor Lloyd Trotman and his team have discovered that menadione kills prostate cancer cells in mice by depleting a lipid known as PIP. Their findings set the stage for pilot studies in human prostate cancer patients and point to a potential treatment target for myotubular myopathy, a rare and fatal disease diagnosed in infant boys.

Prostate cancer is a quiet killer. In most men, it’s treatable. However, in some cases, it resists all known therapies and turns extremely deadly. A new discovery at Cold Spring Harbor Laboratory (CSHL) points to a potentially groundbreaking solution. CSHL Professor Lloyd Trotman’s lab has found that the pro-oxidant supplement menadione slows prostate cancer progression in mice. The supplement is a precursor to vitamin K, commonly found in leafy greens. The story begins more than two decades ago.
