Vascular smooth muscle cells (VSMC) are the predominant cell type in the media of a normal artery. Injury to the vessel wall leads to platelet deposition and the release of numerous factors, including PDGF, which exerts its biological effects by binding to specific surface receptors on the smooth muscle cell membrane. We demonstrate that PDGF-stimulated smooth muscle cells activate the STAT (signal transducers and activators of transcription) family of proteins in addition to other signaling pathways (e.g., RAS-RAF-MAP Kinase). We show that the transcription factor p91 (STAT1 alpha) is rapidly activated by PDGF in VSMC and specifically binds to the regulatory elements SIE or GAS. We hypothesize that signal transduction by p91 plays an important role in VSMC, especially after injury with the release of growth factors such as PDGF.
