1 We recently found with differential display polymerase chain reaction that valproate regulates the expression of the endoplasmic reticulum stress protein GRP78 in the rat cerebral cortex. Valproic Acid heat shock protein family A (Hsp70) member 5 Rattus norvegicus
2 METHODS: Immunohistochemistry was used to measure protein levels of GRP78, GRP94, and calreticulin after treatment with sodium valproate (300 mg/kg, intraperitoneal) in specific rat brain regions. Valproic Acid heat shock protein family A (Hsp70) member 5 Rattus norvegicus
3 CONCLUSIONS: Because GRP78, GRP94, and calreticulin possess molecular chaperone activity and bind Ca(2+) in the endoplasmic reticulum, the pharmacologic action of valproate may involve one or more of these processes. Valproic Acid heat shock protein family A (Hsp70) member 5 Rattus norvegicus
