综述---细胞凋亡机理和应用
摘要：细胞凋亡是一个由基因调控细胞主动死亡过程，是机体生长发育、细胞分化、生理及病理性死亡关键机制。线粒体、肿瘤坏死因子、受体基因DNA降解、凋亡因子、内质网和缺氧条件全部会造成细胞凋亡。细胞选择不一样死亡路径，往往由造成细胞死亡起始原因所决定。细胞凋亡有害也有利，如会引发肿瘤、本身免疫疾病等等。细胞凋亡在机体组织改建过程中起着不可替换作用。细胞凋亡是机体一个基础生理机制，贯穿机体整个生命活动过程，为机体正常细胞更新和异常细胞清除提供了手段，对维持个体正常生理过程和功效表示具重大生物学意义。细胞凋亡多年来已成为细胞生物学和分子生物学研究热点，对细胞凋亡机理深入探讨可对部分疾病包含癌症提供新诊疗方法和路径，现在药品开发多是从病理过程中分子机制、正常生理过程起作用因子来寻求新药。

Review - cell apoptosis mechanism and application
Abstract: Apoptosis is an initiative by cell death process is the body's growth and development, cell differentiation, physiological and pathological death important mechanism. Mitochondria, tumor necrosis factor, receptor gene DNA degradation, apoptosis factor, endoplasmic reticulum and anoxic conditions would lead to a cell apoptosis. Cells choose different death way by causing cell death, often determined by the initial cause. Apoptosis harmful, such as will cause was good tumors, an autoimmune disease, etc. Apoptosis body organization restructuring in plays an irreplaceable role. Apoptosis is a basic body throughout the body physiological mechanism, whole life activities, as the body's normal cells during the update and abnormal cells provides measures to remove, the physiological processes and to maintain the normal function of
