The role of Syk in migration and proliferation of the vascular smooth muscle cells

Spleen tyrosine kinase(Syk) has been considered to be a signaling molecule of hematopoietic cells,which play an important role in lymphocyte maturation and activation of immune cells.Recent studies showed that Syk plays a crucial role in regulation of proliferation and migration in vascular smooth muscle cells.Prominent pathways include mitogen-activated protein kinases,phosphatidylinositol 3-kinases,Src and Rho-activated protein kinase.In this review,the role of Syk in those signal pathways is summarized. Key words: Spleen tyrosine kinase; Vascular smooth muscle cells; Signal transduction
