Mechanotransduction in skeletal muscle.

Mechanical signals are critical to the development and maintenance of skeletal muscle, but the mechanisms that convert these shape changes to biochemical signals is not known. When a deformation is imposed on a muscle, changes in cellular and molecular conformations link the mechanical forces with biochemical signals, and the close integration of mechanical signals with electrical, metabolic, a...

YAP-Mediated Mechanotransduction in Skeletal Muscle

Skeletal muscle is not only translating chemical energy into mechanical work, it is also a highly adaptive and regenerative tissue whose architecture and functionality is determined by its mechanical and physical environment. Processing intra- and extracellular mechanical signaling cues contributes to the regulation of cell growth, survival, migration and differentiation. Yes-associated Protein...

Detyrosinated microtubules modulate mechanotransduction in heart and skeletal muscle

In striated muscle, X-ROS is the mechanotransduction pathway by which mechanical stress transduced by the microtubule network elicits reactive oxygen species. X-ROS tunes Ca(2+) signalling in healthy muscle, but in diseases such as Duchenne muscular dystrophy (DMD), microtubule alterations drive elevated X-ROS, disrupting Ca(2+) homeostasis and impairing function. Here we show that detyrosinati...

Mechanotransduction and the regulation of protein synthesis in skeletal muscle.

Repeated bouts of resistance exercise produce an increase in skeletal muscle mass. The accumulation of protein associated with the growth process results from a net increase in protein synthesis relative to breakdown. While the effect of resistance exercise on muscle mass has long been recognized, the mechanisms underlying the link between high-resistance contractions and the regulation of prot...

FAK-Mediated Mechanotransduction in Skeletal Regeneration

The majority of cells are equipped to detect and decipher physical stimuli, and then react to these stimuli in a cell type-specific manner. Ultimately, these cellular behaviors are synchronized to produce a tissue response, but how this is achieved remains enigmatic. Here, we investigated the genetic basis for mechanotransduction using the bone marrow as a model system. We found that physical s...
