Response and function of skeletal muscle heat shock protein 70.
In response to stress, cells produce a series of heat shock proteins (Hsps). One of the most prominent Hsps, is the 70 kDa Hsp (Hsp70). Hsp70 is a highly conserved and essential protein against stress. The skeletal muscle responds to a diverse group of stress signals namely, muscle contraction linked energy and milieu challenges, ischemia and exercise by producing Hsp70. The extent of this Hsp7...
متن کاملThe response of apoptotic and proteolytic systems to repeated heat stress in atrophied rat skeletal muscle
We examined the effect of repeated heat stress on muscle atrophy, and apoptotic and proteolytic regulation in unloaded rat slow- and fast-type skeletal muscles. Forty male Wistar rats (11 week-old) were divided into control (CT), hindlimb unweighting (HU), intermittent weight-bearing during HU (HU + IWB), and intermittent weight-bearing with heat stress during HU (41-41.5°C for 30 min; HU + IWB...
متن کاملElevation in heat shock protein 72 mRNA following contractions in isolated single skeletal muscle fibers.
The purpose of the present study was 1) to develop a stable model for measuring contraction-induced elevations in mRNA in single skeletal muscle fibers and 2) to utilize this model to investigate the response of heat shock protein 72 (HSP72) mRNA following an acute bout of fatiguing contractions. Living, intact skeletal muscle fibers were microdissected from lumbrical muscle of Xenopus laevis a...
متن کاملSexual dimorphism of the intracellular heat shock protein 72 response.
The majority of previous work examining stress responses has been done in males. Recently, it has become clear that the impact of stressor exposure is modulated by sex. One stress response that may be affected by sex is the induction of intracellular heat shock protein (HSP) 72, which is a stress- responsive molecular chaperone that refolds denatured proteins and promotes cellular survival. The...
متن کاملSprint-interval training induces heat shock protein 72 in rat skeletal muscles.
Previous studies have demonstrated that endurance exercise training increases the level of heat shock proteins (HSPs) in skeletal muscles. However, little attention has been drawn to the effects of high intensity-short duration exercise, or sprint- interval training (SIT) on HSP72 level in rat skeletal muscles. This study performed to test the hypothesis that the SIT would induce the HSP72 in f...
