Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

From arthritis and heart failure to diabetes and menopause, many conditions are associated with muscle weakness and increased fat deposits. Now a multidisciplinary team of researchers at the ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

A new study has observed differences in the shape, structure and mechanical properties of nuclei in trained and untrained individuals, potentially helping to explain the anti-aging effects of exercise ...

Muscle loss (atrophy) due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly ...

The mechanism for muscle stem cells repair could inspire therapeutics for muscle loss caused by injury, aging and weight-loss ...

Voluntary muscles can be controlled by the person, like muscles in your neck and legs. Involuntary muscles work without you thinking about it, like your heart and stomach muscles. Skeletal muscles ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle ...

Researchers identified a molecular pathway that can limit muscle repair, a finding that may guide future muscular dystrophy treatments.

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function ...
