Researchers from Kyushu University have developed an antibody that targets and prevents the dysfunction of hepatocyte growth factor (HGF), a critical protein for skeletal muscle development, regeneration, and repair. The new antibody, 1H42F4N, blocked nitration of HGF and did not disrupt its activity.
University of California San Diego researchers used cryo-electron microscopy to capture the first 3-D images of a key muscle receptor, shedding light on why newborn humans develop slowly while cows mature quickly. The study's findings may help develop future treatments for muscular disorders.

Muscle-tendon attachments must resist high mechanical forces for life, but surprisingly few Talin molecules experience detectable forces at developing attachments. To cope with increasing tissue forces, muscles recruit a large number of Talin molecules to share the peak forces produced during contractions.
