ApoptoticDNAfragmentationandtissuehomeostasis
Apoptotic cell death can be triggered by many different cellular stimuli, resulting in activation of apoptotic signaling pathways including caspases (see Caspase Cascade pathway) and mitochondria (see Role of Mitochondria in Apoptotic Signaling pathway). A cellular response that is characteristic of apoptosis is fragmentation of the nuclear genome to create a nucleosomal ladder. This activity is conducted by multiple......阅读全文
BCL2A1基因突变与药物因子介绍
这个基因编码bcl-2蛋白家族的一个成员。这个家族的蛋白质形成异二聚体或同二聚体,并作为抗和促凋亡调节因子,参与多种细胞活动,如胚胎发育、体内平衡和肿瘤发生。该基因编码的蛋白能减少线粒体前凋亡细胞色素c的释放,阻断caspase的激活。该基因是nf-kappa b对炎症介质的直接转录靶点,受粒细胞巨

抗凋亡基因(CED9)提高植株对盐胁迫和氧化应激的耐...
抗凋亡基因(CED-9)提高植株对盐胁迫和氧化应激的耐受性凋亡(Apoptosis)是细胞程序性死亡的一种,在调节植物对环境的适应性中起到重要作用。近期有研究表明动物的抗凋亡基因(CED-9)在植物中表达,能够显著提高植物对各种生物和非生物胁迫的耐受性,但隐藏在该现象下的最基本的细胞机制尚未被考察。
