Brain-gut induction of heat shock protein (HSP) 70 mRNA by psychophysiological stress in rats.
Restraint water-immersion stress-induced expression of heat shock protein (HSP)70 mRNA in the cerebral cortex and stomach of rats was evaluated by Northern blotting. Cerebral and gastric HSP70 mRNA significantly increased in the 6 h-stressed rats and the amount of mRNA measured as optical densities was highest in the 12 h-stressed rats. These data confirmed our previous observations and suggest that families of HSPs play a salient cytoprotective role in stress-vulnerable organs.
