Drugs That Affect Serotonin Signaling May Combat Bone Loss
Scientists have long known that calcium leaches from the bones both during lactation and in certain types of cancer. The driver behind these phenomena is a molecule called parathyroid hormone related protein (PTHrP), which is secreted by the mammary glands. The signal that regulates the secretion of PTHrP, and where this other unknown molecule exerts its influence, has remained a mystery...

New Approach To Fighting Cancer - New Combo Of Chemo And Malaria Drug Delivers Double Punch To Tumors
Blocking autophagy - the process of "self-eating" within cells -- is turning out to be a viable way to enhance the effectiveness of a wide variety of cancer treatments. Specifically, blocking the action of an acidic inner cell part, which acts like a stomach and chews up proteins for recycling, is the main attack strategy, says Ravi K...
