Researchers identify and block protein that interferes with appetite-suppressing hormone
Ever since the appetite-regulation hormone called leptin was discovered in 1994, scientists have sought to understand the mechanisms that control its action. It was known that leptin was made by fat cells, reduced appetite ...

Fatheads: How neurons protect themselves against excess fat
We're all fatheads. That is, our brain cells are packed with fat molecules, more of them than almost any other cell type. Still, if the brain cells' fat content gets too high, they'll be in trouble. In a recent study in mice, ...

Loss of tumor suppressor SPOP releases cancer potential of SRC-3
Mutations in a protein called SPOP (speckle-type POZ protein) disarm it, allowing another protein called steroid receptor coactivator-3 (SRC-3) to encourage the proliferation and spread of prostate cancer cells, said researchers ...
