  • biopsies
  • Upon re-examination of biopsies from power-lifters, power-lifters using anabolic substances and untrained subjects it was observed that the new results on satellite cell frequency were significantly different from those obtained when using staining for NCAM and nuclei alone. (diva-portal.org)
  • atrophy
  • Since exercise can improve muscle strength and endurance capacity, it can serve as a means of preventing muscle atrophy and reducing the risk of sarcopenia. (hindawi.com)
  • The factors responsible for the atrophy of skeletal muscle with aging remain to be elucidated. (sciencemag.org)
  • Modern medicine's understanding of the quick onset of muscle atrophy is a major factor behind the practice of getting hospitalized patients out of bed and moving about as active as possible as soon as is feasible, despite sutures, wounds, broken bones and pain. (wikipedia.org)
  • Moreover, starvation eventually leads to muscle atrophy. (wikipedia.org)
  • Neurogenic atrophy, which has a similar effect, is muscle atrophy resulting from damage to the nerve which stimulates the muscle, causing a shriveling around otherwise healthy limbs. (wikipedia.org)
  • Disuse atrophy of muscles and bones, with loss of mass and strength, can occur after prolonged immobility, such as extended bedrest, or having a body part in a cast (living in darkness for the eye, bedridden for the legs etc. (wikipedia.org)
  • Astronauts in microgravity must exercise regularly to minimize atrophy of their limb muscles. (wikipedia.org)
  • There are many diseases and conditions which cause atrophy of muscle mass. (wikipedia.org)
  • Changes in Na+ channel isoform expression and spontaneous activity in muscle called fibrillation can also result in muscle atrophy. (wikipedia.org)
  • molecular
  • These results indicate the effects of resistance exercise on the regulation of satellite cells and provide insight into the molecular mechanism of satellite cell activation following physical exercise. (hindawi.com)
  • The molecular mechanism involved in the transition of a quiescent satellite cell to a transit-amplifying myoblast is poorly understood. (biomedcentral.com)
  • The researchers were able to identify the minimal conditions and factors that would be sufficient for starting the cascade of molecular and cellular processes to instruct pluripotent cells to organize the embryo. (wikipedia.org)
  • extracellular
  • ets1 is involved in extracellular matrix (ECM) degradation which is an important process required for tumor cell invasion and migration. (wikipedia.org)
  • proliferative
  • A population's "growth fraction" - or the fraction of the population that was growing - was actively proliferating, but other cells existed in a non-proliferative state. (wikipedia.org)
  • proteins
  • Heterotrimeric G proteins are intracellular proteins and transduce external signals from a variety of cell surface receptors to intracellular effectors ( 1 ). (asm.org)
  • Actins are highly conserved proteins that are involved in cell motility, structure and integrity. (wikipedia.org)
  • SRF may bring a number of other proteins to the promoter of skeletal actin, such as andogen receptor, and thereby contribute to induction of skeletal actin gene expression by androgenic (often termed "anabolic") steroids. (wikipedia.org)
