Promising Cancer Drug Target In Prostate Tumors Identified

Scientists report they have blocked the development of prostate tumors in cancer-prone mice by knocking out a molecular unit they describe as a "powerhouse" that drives runaway cell growth. The researchers say the growth-stimulating molecule called p110beta -- part of a cellular signaling network disrupted in several common cancers -- is a promising target for novel cancer therapies designed to shut it down.
