Impaired overload-induced hypertrophy in obese Zucker rat slow-twitch skeletal muscle.
The effect of insulin resistance (IR) on the adaptation of skeletal muscle loading is not well understood. Here we examine whether the soleus muscles of the lean Zucker (LZ) and insulin-resistant obese Zucker (OZ) rat exhibit differences in their ability to undergo muscle hypertrophy following 8 wk of mechanical overload. Four-week-old male LZ (n = 5) and OZ (n = 5) rats underwent unilateral su...
متن کاملChronic hypobaric hypoxia increases isolated rat fast-twitch and slow-twitch limb muscle force and fatigue.
Chronic hypoxia alters respiratory muscle force and fatigue, effects that could be attributed to hypoxia and/or increased activation due to hyperventilation. We hypothesized that chronic hypoxia is associated with phenotypic change in non-respiratory muscles and therefore we tested the hypothesis that chronic hypobaric hypoxia increases limb muscle force and fatigue. Adult male Wistar rats were...
متن کاملThe trophic effect of ciliary neurotrophic factor on injured masseter muscle in rat
Objective(s): Occlusal trauma is one of the most common forms of oral biting dysfunction. Long-term occlusal trauma could weaken the stomatognathic system; especially damage one’s masticatory muscle. Through using the rat model, this study investigated the trophic effect of ciliary neurotrophic factor (CNTF) on injured masseter muscle. Materials and Methods: Male Wistar rats (n=36) were random...
متن کاملHistone deacetylase degradation and MEF2 activation promote the formation of slow-twitch myofibers.
Skeletal muscle is composed of heterogeneous myofibers with distinctive rates of contraction, metabolic properties, and susceptibility to fatigue. We show that class II histone deacetylase (HDAC) proteins, which function as transcriptional repressors of the myocyte enhancer factor 2 (MEF2) transcription factor, fail to accumulate in the soleus, a slow muscle, compared with fast muscles (e.g., w...
متن کاملGDNF Content and NMJ Plasticity in Slow and Fast Twitch Myofibers Follows Recruitment in Exercise
Glial cell line-derived neurotrophic factor (GDNF)supports and maintains the neuromuscular system duringdevelopment and through adulthood by promoting neuro-plasticity. The aim of this study was to determine if differentmodes of exercise can promote changes in GDNF expres-sion and neuromuscular junction (NMJ) morphology inslowand fast-twitch muscles. Rats were randomly<l...
