Transcription profiling of rat aortic smooth muscle cells to assess the functional relevance of tetraspanin CD9 in vascular smooth muscle cell injury

ABSTRACT: Vascular smooth muscle cell (VSMC) migration and proliferation are critical events in the development of neointima following vascular injury. Exogenous expression of human CD9 by CD9-adenoviral transduction led to increases in neointima. CD9 expression significantly augmented PI-3 kinase dependent Akt phosphorylation with concurrent adhesion to extracellular matrix protein fibronectin (FN). Furthermore,enhanced Akt phosphorylation was attenuated by anti-CD9 mAb7 binding. As multiple factors contribute to the regulation of VSMC phenotype, our aim was to establish whether increased CD9 expression would induce changes in the expression of other genes associated with VSMC proliferation and motility. RASM were transduced with either CD9 adenovirus or control and were plated on FN for 6hours
