Study On Guppies Sheds Light On Long-Term Costs Of Early Rapid Growth And Weight Gain

University of California, Riverside biologists working on guppies - small freshwater fish that have been the subject of long-term studies - report that rapid growth responses to increased food availability after a period of growth restriction early in life have repercussions in...

Master Regulator Discovery In Cell Metabolism, Response To Stress, Could Impact Obesity, Diabetes And Cancer Research

AMP-activated protein kinase, or AMPK, is a master regulator protein of metabolism that is conserved from yeast to humans. When a cell is low on fuel, AMPK shuts down processes that use energy and turns on processes that produce...

Unlocking The Secrets Of Cellular Energy Holds Promise For Obesity, Diabetes And Cancer

A breakthrough on how cells regulate their energy is promising for clinical gains into diseases such as obesity, diabetes and cancer. Researchers at McGill University and University of Pennsylvania have uncovered new insights into how a protein known as the AMP-activated protein kinase, or AMPK, a master regulator of metabolism, controls how our cells generate...

Clues To ‘Missing Link’ To Life Found In Peptides

Emory University scientists have discovered that simple peptides can organize into bi-layer membranes. The finding suggests a "missing link" between the pre-biotic Earth's chemical inventory and the organizational scaffolding essential to...
