We examined effects of ischemia on expression of prostaglandin H synthase-1 (PGHS-1) and prostaglandin H synthase-2 (PGHS-2) in piglet choroid plexus. Ten minutes of ischemia was induced by increasing intracranial pressure. Whole choroid plexus was removed and fixed and/or frozen after 1, 2, 4, and 8 h of recovery from anoxic stress. In addition, tissues were obtained from untreated animals or from time control animals. Tissues were analyzed for mRNA, using RNase protection assays, and for proteins, using immunohistochemical approaches. Limited, but detectable PGHS-2 immunoreactivity was present in choroid plexus under normal conditions, and there was no difference between time-control and non-treated animals. Further, PGHS-2 mRNA increased by 2-4 h after ischemia, and enhanced immunoreactivity for PGHS-2 was present at 8 h after ischemia. Enhanced immunoreactivity for PGHS-2 was present in vascular endothelial cells as well as cuboidal epithelial cells and macrophages. In contrast, PGHS-1 mRNA did not increase following ischemia. We conclude that PGHS-2 is present in piglet choroid plexus under normal conditions and that ischemia increases levels of PGHS-2 in choroid plexus.
