Calorie restriction and cellular aging process

Recent research published in Molecular & Cellular Proteomics offers one glimpse into how cutting calories impacts aging inside a cell. The researchers found that when ribosomes – the cell’s protein makers – slow down, the aging process slows too. The decreased speed lowers production but gives ribosomes extra time to repair themselves. Repairing individual parts …

Understanding signaling pathway that creates brown fat to help in fight against obesity and diabetes

A signaling pathway in fat cells may one day provide the key to better treatments for obesity, according to new research by scientists at the Perelman School of Medicine at the University of Pennsylvania. They reported their findings in Genes & Development. This image shows adipose tissue, with fat droplets in greenand blood vessels in …
