These modified protein(s) regulate activity, localization and interaction with other cellular molecules thereby maintaining cellular hemostasis. Alcohol exposure significantly alters several of these post-translational modifications leading to impairments of many essential physiological processes. Here, we present new insights into novel modifications following ethanol exposure and their role in the initiation and progression of liver injury. This critical review condenses the proceedings of a symposium at the European Society for the Biomedical Research on Alcoholism Meeting held September 12-15, 2015, in Valencia, Spain.展开更多

文摘核转录因子(nuclear factorκb,NF-κB)是公认的炎症和免疫反应的调节因子,与糖尿病肾病的发生发展密切相关。小泛素相关修饰物(small ubiquitin-related modifier,sumo)参与了NF-κB信号通路的调控,NF-κB抑制蛋白(inhibitor ofnf-κB,IκB)等NF-κB通路中重要的蛋白因子均可被小泛素相关修饰物修饰,进而调控NF-κB信号通路。sumo化修饰酶在该调控中发挥极其重要的作用,其中sumo结合酶E2(即ubc9蛋白)和sumo连接酶E3成员之一的信号转导和转录激活子(signal transducer and activator of transcription,STAT)抑制蛋白(protein inhibitor of activated STAT,PIAS)家族是近年来的研究热点。文中综述sumo化、sumo化修饰酶及其对糖尿病肾病NF-κb信号通路的调控作用。
