Prostaglandin E2 induces vascular endothelial growth factor and basic fibroblast growth factor mRNA expression in cultured rat Müller cells.

Abstract

These results indicate that PGE2 stimulates VEGF and bFGF mRNA expression in cultured rat Müller cells. The induction of VEGF seems to occur through activation of the PKA pathway, whereas that of bFGF occurs through PKA and PKC activation. These findings raise the possibility that endogenous PGE2 stimulates VEGF and bFGF mRNA expression in Müller cells in vivo under conditions in which PGE2 production is increased, such as in injury.
