title: Induction of PGH synthase and c-fos mRNA during early reperfusion of ischemic rat brain.
abstract: We examined the effect of reversible ischemia on the transcription of prostaglandin endoperoxide synthase (PGHS-1) and c-fos mRNA in rat cerebral cortex. The level of PGHS-1 mRNA climaxed after 30 min of ischemia whereas transcription of c-fos mRNA peaked after 60 min of postischemic reperfusion. We conclude that cerebral ischemia causes early transcription of PGHS-1, without modulation by the c-fos gene or its translated product.
