Phenotypic Plasticity in Skeletal Muscle
Anyone training for a marathon knows that although the goal may at first seem unattainable, with the correct exercise regime, even the least promising athlete will eventually cross the finish line. This remarkable phenotypic plasticity, which allows us to reshape our bodies within the strictures of our genetic make-up, has fascinated scientists for the last 3 decades. However, Hans Hoppeler exp...
متن کاملSizes of components in frog skeletal muscle measured by methods of stereology
Stereological techniques of point and intersection counting were used to measure morphological parameters from light and electron micrographs of frog skeletal muscle. Results for sartorius muscle are as follows: myofibrils comprise 83% of fiber volume; their surface to volume ratio is 3.8 mum-1. Mitochondria comprise 1.6% of fiber volume. Transverse tubules comprise 0.32% of fiber volume, and t...
متن کاملPlasticity in Skeletal, Cardiac, and Smooth Muscle Historical Perspectives: Plasticity of mammalian skeletal muscle
Pette, Dirk. Historical Perspectives: Plasticity of mammalian skeletal muscle. J Appl Physiol 90: 1119–1124, 2001.—More than 40 years ago, the nerve cross-union experiment of Buller, Eccles, and Eccles provided compelling evidence for the essential role of innervation in determining the properties of mammalian skeletal muscle fibers. Moreover, this experiment revealed that terminally differenti...
متن کاملCoordination of metabolic plasticity in skeletal muscle.
Skeletal muscle is a highly malleable tissue, capable of pronounced metabolic and morphological adaptations in response to contractile activity (i.e. exercise). Each bout of contractile activity results in a coordinated alteration in the expression of a variety of nuclear DNA and mitochondrial DNA (mtDNA) gene products, leading to phenotypic adaptations. This results in an increase in muscle mi...
متن کاملPlasticity of Salamander Skeletal Muscle Cells
Regeneration is unevenly spread throughout the animal kingdom. Some of the invertebrates have a very high regenerative capacity but the capacity to replace lost or damaged tissues in mammals is limited. Among the vertebrates, the aquatic salamanders are the champions of regeneration, being able to regenerate body parts such as their limbs, tail, and jaw. Understanding the celland molecular mach...
