摘要 信号转导及转录激活因子(signal transducer andactivator of transcription,STAT)是一组存在于胞浆并在激活后能转入核内的DNA结合蛋白家族,具有信号转导和转录调控的功能。哺乳动物中已发现7种:STAT1、STAT2、STAT3、STAT4、STAT5A、STAT5B和STAT6。STAT蛋白是JAK(Janus kinase)/STAT通路中重要的JAK的底物。JAK是一类非跨膜型的酪氨酸激酶,共有4个成员:JAK1、JAK2、JAK3和TYK2。STAT蛋白广泛表达于机体不同类型的细胞和组织中,参与细胞生长、分化、凋亡等多种生理功能的调控。在正常情况下。 Signal transducer and activator of transcription 3(STAT3),a kind of potential nuclear factor in cytoplasm, is involved in myocardial protection and hypertrophy,and impacts on the vasculature and the extracellular matrix (ECM)via paracrine pathways.By collecting numerous data from experimental and clinical studies,we provide an overview on STAT3 signaling and summarize the current understanding of the role of STAT3 in cardiac remodeling in this review.
