NO to Exercise?

Exercise is good for you. Who hasn’t heard that one before? We know about the benefits of exercise involving weight control, health, mood and energy levels. But is there a genetic aspect that helps exercise reduce the chances of developing certain diseases?

Justin M. Percival, PhD, is an Assistant Professor of Molecular and Cellular Pharmacology at the University of Miami. His research focuses on skeletal muscle nitric oxide (NO) to determine if it enables skeletal muscle to communicate with other organs, and if this communication mediates some of the systemic benefits of exercise. NO is a biomarker of healthy skeletal muscle and NO signalling is known to be important in the cardiovascular, immune and central nervous systems. Healthy skeletal muscles express more neuronal NO synthase (nNOS) whereas unhealthy muscles have less nNOS or defective NO signalling.

Traditionally it has been understood that NO signalling is primarily diffusion limited, in other words, NO gas diffuses randomly to target down a diffusion gradient. Prof. Percival has discovered that skeletal muscle expresses a second neuronal NO synthase (nNOS) called nNOSβ at the Golgi apparatus. Two nNOS enzymes, nNOSµ and nNOSβ, are required for peak muscle performance. They are localised close to each other in muscle, each with a separate function, which is not possible if NO diffuses freely.

Prof. Percival seeks to understand the diverse functions of nNOS splice variant signaling in skeletal muscle using mouse models of muscular dystrophy, obesity and diabetes. He aims to translate his findings into potential therapies for neuromuscular and metabolic diseases. Prof. Percival was part of a team who successfully used sildenafil to increase nNOS signaling and reduce skeletal and cardiac muscle dysfunction in the mdx mouse model of Duchenne muscular dystrophy (DMD). DMD is a genetic disease characterised by muscle weakness and wasting, which leads to respiratory or cardiac failure in people by 30 years of age.

Frank's blog: Good news

This month I’d like to share some good news from the Hempel family, whose daughters suffer from a severe genetic cholesterol condition called Niemann-Pick Type C. It causes cholesterol to build up in cells to toxic levels and is often referred to as childhood Alzheimer’s.
