9756346 Yang YL, Lu KT, Tsay HJ, Lin CH, Lin MT: Heat shock protein expression protects against death following exposure to heatstroke in rats. Neurosci Lett. 1998 Aug 7;252(1):9-12.

Rats 0, 16, or 48 h after heat shock (42 degrees C core temperature for 15 min) or chemical stress (5 mg/kg sodium arsenite, i.p.) were exposed to a high ambient temperature (43 degrees C) to induce heatstroke onset.
Prior heat shock or chemical stress conferred significant protection against heatstroke-induced arterial hypotension, cerebral ischemia, cerebral neuronal damage and death, and correlated with expression of HSP72 in brain, heart, liver and kidney at 16 h.

Initial experiments used one- and two-dimensional polyacrylamide gel electrophoresis to confirm the induction of typical stress protein size classes by heat shock, sodium arsenite, and the calcium ionophore A23187.
Immunoblot analysis and immunocytochemistry verified the expression of the highly inducible 72 kd heat shock protein (HSP72).

In previous studies, the heat shock response, induced by hyperthermia or sodium arsenite, increased interleukin (IL)-6 production in intestinal mucosa and cultured human enterocytes.
Treatment of Caco-2 cells with one of the proteasome inhibitors MG-132 or lactacystin activated the transcription factor heat shock factors (HSF)-1 and -2 and upregulated cellular levels of the 72-kDa heat shock protein HSP-72.

The heat shock response was induced in mice by intraperitoneal injection of 10 mg/kg sodium arsenite.
Two hours later, at which time mucosal heat shock protein 72 levels were increased, sepsis was induced by cecal ligation and puncture (CLP) or sham operation was performed.

The heat shock response is a highly conserved mechanism of protection elicited in the cell by various kinds of stimuli, such as heat, sodium arsenite, oxidants and inflammation.
Such a reduction was associated to activation of heat shock factor, increased levels of heat shock protein 72 and inhibition of lipopolysaccharide-induced nuclear factor-kappaB binding activity.

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 heat shock (42 degrees C for 15 min) or chemical stress (5 mg/kg sodium arsenite ip).

A monoclonal antibody to the 72 kD heat shock protein (HSP 72), Western blot analysis and 2-D gel electrophoresis/autoradiography were used to determine whether selected chemical teratogens induced the synthesis and accumulation of HSP 72 in postimplantation rat embryos exposed in vitro.
