Cell－Death－Differ：前列腺癌恶化标志
前列腺癌是近年来导致西方国家男性死亡的严重癌症之一，扩散性疾病的患者治疗情况也不够乐观。血清中的前列腺特意抗原（PSA）是用于癌症检测的分子标记，但是对于癌症的恶化PSA并不能够达到准确的预测，因此找到一个更加合适的分子标记对于前列腺癌的中期诊断十分重要。另一方面，由于前列腺癌的异质性，至今还没

同济大学毛志勇教授发表Cell－Death－－Differentiation文章
基因组稳定性下降是生物体衰老发生极其重要的一个标志。细胞长期在各种因素的影响下，DNA遭受着多种损伤，若这些损伤不被及时准确地修复将诱发基因组稳定性的下降，进而影响细胞的正常生命活动。这些损伤中，DNA双链断裂（DSBs）是最为严重的基因组损伤之一。近年来，虽然关于DNA DSBs修复与衰老发
Cell－Death－Dis：中风患者遭受脑损伤的新机制
近日，研究人员发现中风患者遭受脑损伤的机制，并正在寻找药物来阻止它。 当供应到大脑的血液被部分切断时中风发生，但对于存活者而言更严重的伤害是记忆和其他认知功能伤害，这些记忆和其他认知功能伤害常常实际上由血液供应恢复后的几小时或几天内“氧化应激”生成过多所引起的。 从Leeds大学和中国浙江大
Cell－Death果蝇DNA损伤后细胞增殖与凋亡的协调
暴露于遗传毒性应激可促进细胞周期停滞和DNA修复或凋亡。这些“生”或“死”细胞命运的决定通常取决于肿瘤抑制基因53的活性。因此，对p53的精确调控对于维持组织内环境平衡和防止肿瘤的发展至关重要。然而，细胞周期进程是如何影响p53细胞命运的，目前尚不清楚。 已经提出了几种机制来解释dna损伤细胞

Cell－Death－Differ：启动肺癌细胞自毁开关的新疗法
近日，英国癌症研究中心科学家们发现了一种药物组合，可以触发肺癌细胞的自毁过程，此项研究为新型治疗方法开发铺平了道路。 当健康细胞对机体不再有用，它们便引发一连串事件最终导致自我毁灭。但癌细胞则突然转向远离这个“自杀道路”，成为不朽，这意味着细胞生长失控，引起肿瘤的形成。 现在，英国癌症研究中

RIPK1与RIPK3被发现是参与细胞坏死性凋亡的关键成员，在caspase家族活性被抑制的情况下，RIPK1激活后能够与下游的RIPK3结合形成坏死小体，帮助RIPK3激活（磷酸化）。磷酸化后的RIPK3再次将MLKL磷酸化，磷酸化后的MLKL能够在细胞膜内侧自聚合形成寡聚体，最终导致细胞坏死
