Maslinic acid from olive-skin pomace protects against colon cancer

Researchers from the University of Granada and the University of Barcelona have shown that treatment with maslinic acid, a triterpenoid compound isolated from olive-skin pomace, results in a significant inhibition of cell proliferation and causes apoptotic death in colon-cancer cells.

Discovery of target that could ease spinal muscular atrophy symptoms

There is no cure for spinal muscular atrophy (SMA), a genetic disorder that causes the weakening of muscles and is the leading genetic cause of infant death, but University of Missouri researchers have discovered a new therapeutic target that improves deteriorating skeletal muscle tissue caused by SMA.

Gene marker may improve odds of stem cell therapies for disease

A single tumor-suppressor gene may provide a unique marker for senescence in Mesenchymal stem cells (MSCs) in vitro, while also playing a role in moving MSCs into senescence, researchers at the Human Health Foundation and the Sbarro Institute for Cancer Research and Molecular Medicine report.
