Molecular mechanisms underlying PGF2alpha-induced hypertrophy of vascular smooth muscle cells.

The present review focuses primarily on the studies we made in recent years to improve the understanding of the molecular mechanisms of PGF2alpha-induced hypertrophy of Vascular Smooth Muscle Cells (VSMC). In this review, we will summarize the recent findings in the context of the PGF2alpha signaling pathway in three parts: PGF2alpha binding to its receptor, transactivation of EGF receptor, two independent signaling transduction pathways increasing the expression of NOX1 gene.
