Scientists at UMDNJ-Robert Wood Johnson Medical School are a step closer to treating, and perhaps preventing, muscle damage caused by neurodegenerative disorders and other forms of disease. In a newly published study, released today and cited as a Paper of the Week by the Journal of Biological Chemistry, the team has discovered that the gene polymerase I and transcript release factor, or PTRF, is an essential component of the cell process that repairs damaged muscle tissue. This discovery has the potential to lead to development of therapeutic treatment for patients who suffer from severe complications of diseases such as muscular dystrophy, cardiovascular disorders and other degenerative conditions.
New research indicates supplementation with the "sunshine vitamin" may be particularly beneficial for overweight African-American adults, a population at increased risk for both cardiovascular disease and vitamin D deficiency.

Many people suffer from a devastating condition known as critical limb ischemia (CLI) that can lead to muscle wasting and even amputation. The disease is linked to the blockage of blood flow to the skeletal muscle and current treatment options include rehabilitative exercise and surgical bypass of blood vessels. New preclinical research suggests there may be a way to restore blood supply in skeletal muscle without traditional intervention.
