Induction of heat shock protein (HSP)72 protects against obesity-induced insulin resistance, but the underlying mechanisms are unknown. Here, we show that HSP72 plays a pivotal role in increasing skeletal muscle mitochondrial number and oxidative metabolism. Mice overexpressing HSP72 in skeletal muscle (HSP72Tg) and control wild-type (WT) mice were fed either a chow or high-fat diet (HFD). Desp...
BACKGROUND Induction of heat-shock proteins (HSPs) results in cardioprotection against ischemic insult. Geranylgeranylacetone (GGA), known as an antiulcer agent, reportedly induces HSP72 in the gastric mucosa and small intestine of rats. The present study tested the hypothesis that oral GGA would induce HSP72 in the heart and thus render cardioprotection against ischemia/reperfusion injury in r...
We tested the hypothesis that pioglitazone could restore expression of heat shock protein (HSP)72 in insulin-resistant rat heart. At 12 weeks of age, male Otsuka Long-Evans Tokushima Fatty (OLETF) rats and control (LETO) rats were treated with pioglitazone (10 mg x kg(-1) x day(-1)) or glibenclamide (5 mg x kg(-1) x day(-1)) for 4 weeks. Thereafter, hyperthermia (43 degrees C for 20 min) was ap...
Evaluation of heat shock protein (HSP-72) expression in retinal ganglion cells of rats with glaucoma
The present study was planned to observe the expression of heat shock protein 72 (HSP72) in retina of rats in a glaucoma model. A total of 50 Wistar rats were randomly divided into the high intraocular tension group (glaucoma model) and the sham control (sham operation) group. Glaucoma rat models were created by application of electrocoagulation on at least three groups of veins, reduction of v...
The expression of myocardial heat shock protein 72 (HSP72) postexercise is initiated by the activation of heat shock transcription factor 1 (HSF1). However, it remains unknown which physiological stimuli govern myocardial HSF1 activation during exercise. These experiments tested the hypothesis that thermal stress and mechanical load, concomitant with simulated exercise, provide independent stim...
Induction of heat shock protein (HSP)72 improves insulin resistance and obesity in diabetic animal models. Geranylgeranylacetone (GGA), known as an antiulcer drug, induces HSP72 and protects organs against several cellular stresses. This study investigated whether GGA administration would induce HSP72 in liver and render physiological protection against high-fat feeding in mice. A single and 4-...
Effects of heat shock transcription factor 1 (HSF1) gene on the regrowth of atrophied mouse soleus muscles were studied. Both HSF1-null and wild-type mice were subjected to continuous hindlimb suspension for 2 wk followed by 4 wk of ambulation recovery. There was no difference in the magnitude of suspension-related decrease of muscle weight, protein content, and the cross-sectional area of musc...
In a companion paper in this journal, Amorim and coworkers reviewed recent human studies which show that Heat Shock Proteins (HSP72 and possibly HSP90) are elevated during heat acclimation. They suggest that these cellular changes result in both cellular and whole body thermotolerance. Thermotolerance after an initial sub-lethal heat exposure, has been shown repeatedly in cell studies, and has ...
A68, or PHF-tau, is an abnormally phosphorylated form of the microtubule-associated protein tau, which is a primary protein constituent of paired helical filaments (PHFs) and, ultimately, of Alzheimer's disease-associated neurofibrillary tangles (NFTs). Previously, we have shown that in heat-shocked neuronal PC12 cells, tau is hyperphosphorylated and transformed to an A68-like state as determin...
