Expression of stress proteins HSP 72 & HSP 32 in response to endotoxemia.
Pretreatment with heat decreases mortality and acute lung injury in the rat septic shock model, presumably by the production of heat shock proteins (HSP). However, endotoxin, a severe cell stresser, has not been shown to induce HSP 70. We investigated the effects of severe endotoxemia on the expression of specific protective stress proteins, including HSP 72 (inducible HSP 70), HSP 32 (heme oxy...
متن کاملATP releases HSP-72 from protein aggregates after renal ischemia.
The pattern of 72-kDa heat-shock protein (HSP-72) induction after renal ischemia suggests a role in restoring cell structure. HSP-72 activity in the repair and release from denatured and aggregated proteins requires ATP. Protein aggregates were purified from normal and ischemic rat renal cortex. The addition of ATP to cortical homogenates reduced HSP-72, Na+-K+-ATPase, and actin in aggregates s...
متن کاملHeat shock protein 72 overexpression protects against hyperthermia, circulatory shock, and cerebral ischemia during heatstroke.
This study extends our earlier studies in rats by applying our heatstroke model to a new species. Additionally, transgenic mice are used to examine the role of heat shock protein (HSP) 72 in experimental heatstroke. Transgenic mice that were heterozygous for a porcine HSP70i gene ([+]HSP72), transgene-negative littermate controls ([-]HSP72), and normal Institute of Cancer Research strain mice (...
متن کاملEvaluation 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...
متن کاملHeat shock protein expression protects against cerebral ischemia and monoamine overload in rat heatstroke.
This study attempted to ascertain whether the ischemic damage to neurons and monoamine overload in brain that occur during rat heatstroke can be attenuated by heat shock protein (HSP) 72 induction. Effects of heatstroke on mean arterial pressure (MAP), cerebral blood flow (CBF), brain dopamine (DA) and serotonin (5-HT) release, and neural damage score were assayed in rats 0, 16, or 48 h after h...
