There is a reason exercise becomes more difficult with age. A report in the August Cell Metabolism, a Cell Press publication, ties the weakness of aging to leaky calcium channels inside muscle cells. But there is some good news: the researchers say a drug already in Phase II clinical trials for the treatment of heart failure might plug those leaks. Earlier studies by the research team led by Andrew Marks of Columbia University showed the same leaks underlie the weakness and fatigue that come...

Researchers at the Perelman School of Medicine at the University of Pennsylvania have identified a gene for endurance, or more precisely, a negative regulator of it. Not having the gene relates to greater endurance in the knockout mice that were studied. The investigators also showed that the gene is linked to Olympic-level athletes in endurance sports such as swimming compared to athletes in sprint sports such as the 100-meter dash. The study appears online this week in the Journal of...

Research led by the University of East Anglia has discovered the crucial role of a molecule in skeletal muscle development. The finding could have implications in the future for maintenance of healthy muscle or muscle regeneration in certain diseases, for example cancer and neuromuscular conditions such as muscular dystrophy. The complexity and significance of microRNA molecules has only recently been recognized and they have been implicated in many biological processes, including disease....

New York Medical College scientist proposes a new theory of the origin of birds A developmental biologist at New York Medical College is proposing a new theory of the origin of birds, which traditionally has been thought to be driven by the evolution of flight. Instead, Stuart A. Newman, Ph.D., credits the emergence of enlarged skeletal muscles as the basis for their upright two-leggedness, which led to the opportunity for other adaptive changes like flying or swimming. And it is all based on...

Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell's territory, eventually forcing the cells to combine. Such muscle cell fusion, the researchers say, is not only important for understanding normal muscle growth, but also muscle regeneration after injury or disease. The work, they believe, could further development of therapies for muscular...

Fast muscles, such as the thigh muscle in a sprinter, deliver energy quickly but fatigue quickly. Slow muscles, such as the soleus muscle in the lower calf, are less forceful but important for posture and endurance. Researchers from the University of Texas Southwestern Medical Center and Virginia Tech have discovered one gene regulator that maintains the fast muscle type and inhibits the development of a slow muscle type. The research was posted in the Proceedings of the National Academy of...

New research in the FASEB Journal suggests that protein drinks help older subjects build more formidable muscles than their counterparts who drink carbohydrate beverages A new research report appearing online in the FASEB Journal (http://www.fasebj.org) shows that what someone drinks after exercise plays a critical role in maximizing the effects of exercise. Specifically, the report shows that protein drinks after aerobic activity increases the training effect after six weeks, when compared...

Obesity appears to impair normal muscle function in rats, an observation that could have significant implications for humans, according to Penn State researchers. "Our findings demonstrate that obesity involves more than accumulating excess fat and carrying excess weight," said Rudolf J. Schilder, American Physiological Society postdoctoral fellow in physiological genomics, Penn State College of Medicine. "We show that, during the development of obesity, skeletal muscles fail to adjust their...

New insight into the physiology of cardiac muscle may lead to the development of therapeutic strategies that exploit an inherent protective state of the heart. The research, published by Cell Press online on April 19th in the Biophysical Journal, discovers a state of cardiac muscle that exhibits a low metabolic rate and may help to regulate energy use and promote efficiency in this hard-working and vital organ. Muscle cells are highly specialized cells that are able to physically contract and...
