基因敲除去乙酰化酶SIRT1并靶向结合miR-138-5p诱导前列腺癌细胞PC-3氧化应激和凋亡
Zhongguo shiyan zhenduanxue, 2020 目的沉默信息调节因子1(silent information regulator 1,SIRT1)是一种依赖烟酰胺腺嘌呤二核苷酸(NAD+)的组蛋白去乙酰化酶,可作为致癌基因通过抗凋亡活性在肿瘤发生中起作用,并涉及自噬,衰老,凋亡,增殖等多种细胞过程。因此,本研究通过基因敲除去乙酰化酶SIRT1,探究其对靶向结合miR-138b-5p对前列腺癌细胞PC-3氧化应激和凋亡的作用。方法设计合成SIRT1shRNA,将inhibitor和shRNA-SIRT1单独或联合转染PC-3细胞,RT-PCR检测miR-

Zhongshan Daxue xuebao. Yixue kexue ban线粒体自噬是一种进化上高度保守的选择性自噬过程，通过特异性识别并清除功能受损或多余的线粒体，以维持细胞内稳态和线粒体质量监控。在肿瘤发生过程中，线粒体自噬可清除受损线粒体，减少活性氧（ROS）积累，从而维持细胞稳态。能量代谢是指细胞通过糖酵解、氧化磷酸化等生化过程将营养物质中的化学能转化为三磷酸腺苷（ATP），为细胞生命活动提供能量的核心生物学过程。目前消化道肿瘤的研究现状不断进展，但目前的瓶颈在于其复杂的代谢适应性与治疗耐药性。靶向线粒体自噬与能量代谢的交互作用成为治疗该疾病的一种新兴策略 ...

ROS via promoting RIP1 auto-phosphorylation to enhance TNF-induced necrosome formation and subsequent necroptosis [PDF]
, 2015 活性氧（ReactiveOxygenSpecies，ROS）的产生存在于生物体的众多生理病理过程中。大量的实验数据表明，活性氧还参与到了细胞凋亡和程序性坏死的进程里。丁基羟基苯甲醚（Butylatedhydroxyanisole，BHA）是公认的活性氧清除剂，异戊巴比妥（Amytal）是线粒体上电子传递到泛醌的抑制剂，二者都曾被广泛报道，可以抑制或者延缓肿瘤坏死因子（TumorNecroticFactorα，TNF-α）诱导的小鼠成纤维细胞系L929的程序性细胞坏死。然而 ...

Zhongguo shiyan zhenduanxue线粒体在细胞能量代谢、增殖、凋亡等过程中发挥关键作用，其功能异常与肿瘤的发生和发展密切相关。肿瘤细胞通过代谢重编程，优先依赖糖酵解而非氧化磷酸化来生成能量，这种现象称为“Warburg效应”。这种代谢方式为肿瘤细胞提供了增殖、转移所需的物质和能量基础。此外，线粒体功能的损伤导致能量供应不足，并促进了肿瘤细胞的生长和免疫逃逸。线粒体自噬作为一种细胞质量控制机制，通过去除受损线粒体来调节细胞能量代谢，其功能的异常可能促进肿瘤进展或增强化疗耐药性。线粒体自噬的作用在不同类型肿瘤中的影响复杂 ...
