中文摘要：
哺乳动物雷帕霉素靶蛋白（mammalian target of rapamycin，mTOR）是一种非典型丝氨酸／苏氨酸蛋白激酶，可整合营养、能最及生长闲予等多种细胞外信巴，参与基因转录、蛋白质翻译、核精体合成等生物过程，杠细胞生长和细胞程序性死亡中发挥极为蘑要的作用。研究表明，mTOR信号通路可能通过调节下游靶蛋白来调控细胞生物过程，如缺氧诱导因子（hypoxia—induciblefactr,HIF-1α），血管内皮生长因子（vascular endothelial growth factor.VEGF）等。mTOR通过调节这些细胞因子，可能影响蛋白质合成、血管生成和细胞凋亡自噬等，从而影响疾病发展和结局，这为mTOR成为疾病治疗靶点提供证据。
英文摘要：
The mammalian target of rapamycin （mTOR） is an evolutionarily conserved atypical Ser/Thr protein kinase, functioning as a sensor of extracellular signals from nutrients, oxygen, energy and growth factors. Through modulating its downstream targets in the cellular nucleus, roTOR regulates transcription, cell growth, protein translation, proliferation, survival and programmed cell death. It is proved that mTOR can regulate the cellular biological processes through some cytokines, such as hypoxia-inducible factor （HIF-1α）, vascular endothelial growth factor （VEGF）, etc. These processes include protein synthesis, angiogenesis, apoptosis or autophagy, which participate in the pathological or survival mechanisms of diseases. Therefore, roTOR could become a candidate target for treatment of diseases.
