自1979年被发现以来,p53蛋白已成为了研究最为广泛和深入的肿瘤抑制因子之一。作为转录因子,p53调控众多下游信号通路,诱导细胞周期停滞、细胞凋亡和衰老是其最“经典”的功能,也被认为是其清除受损细胞、防止癌细胞发生的主要手段。学术经纬相关阅读:人类 ...
本期推荐:研究团队发现跨谷氨酰胺酶2(TG2)通过催化组蛋白H3K4me3的血清素化(H3K4me3Q5ser),阻止Ripk3启动子甲基化从而促进其表达,揭示了TG2在坏死性凋亡(necroptosis)通路中的新型表观遗传调控机制,为炎症性疾病和肿瘤治疗提供新靶点。 细胞死亡调控领域 ...

当细胞受到病毒感染等刺激时,病毒的核酸或其他病原体相关分子模式(PAMPs)可诱导细胞内产生 Z - DNA,ZBP1 识别并结合这些 Z - DNA 后,可激活下游的免疫信号通路,如通过 RHIM 结构域招募并激活受体相互作用蛋白激酶 1(RIPK1)和 RIPK3,进而引发细胞炎症反应和 ...
Z-DNA 结合蛋白 1(ZBP1)已成为癌症生物学中的关键调控因子,作为细胞质中的核酸传感器,它可触发 PANoptosis——一种整合了焦亡(pyroptosis)、凋亡(apoptosis)和坏死性凋亡(necroptosis)的程序性细胞死亡形式。尽管 ZBP1 最初因其在抗病毒防御中的作用而被发现 ...
与增殖细胞不同,神经元中 RIPK3 的激活不会诱导坏死性凋亡(necroptosis),而是产生抗病毒转录反应。研究表明,在皮质神经元中,RIPK3 依赖的转录反应需要其他含 RHIM 结构域的蛋白 RIPK1(受体相互作用蛋白激酶 1)和 TRIF(TIR 结构域衔接蛋白诱导 IFN-β),这 ...
