Strategy might thwart resistance to a common prostate cancer treatment

Conventional wisdom has it that high levels of testosterone help prostate cancers grow. However, a new, small study suggests that a treatment strategy called bipolar androgen therapy—where patients alternate between low and high levels of testosterone—might make prostate tumors more responsive to standard hormonal therapy. As the researchers explained, the primary treatment for advanced prostate cancer is hormonal therapy, which lowers levels of testosterone to prevent the tumor from growing. But there’s a problem: Prostate

Scientists identify first nutrient sensor in key growth-regulating metabolic pathway

Known as much for its complexity as its vital role in regulating cellular and organismal growth, the mechanistic target of rapamycin complex 1 (mTORC1) pathway has seemingly been acting in mysterious ways. Through a variety of mechanistic interactions, mTORC1 interprets cues in the cellular environment, including the availability of nutrients, and signals the organism to act accordingly. mTORC1 is apt to trigger growth during times of abundance and dial back metabolism when food is scarce.
