摘　　要：背景:不同于非炎症性细胞凋亡,细胞焦亡是炎症性细胞死亡的一种形式,它伴随着膜完整性的破坏和促炎性细胞内物质的释放,因而与多种疾病有关。沉默信息调节因子家族是依赖于烟酰胺腺嘌呤二核苷酸的组蛋白去乙酰化酶家族。除了去乙酰化外,还具有其他酶活性,如脱琥珀酸化、脱丙酰化和腺苷二磷酸-核糖基化等,在参与细胞焦亡调控中发挥重要的作用。目的:综述沉默信息调节因子家族在细胞焦亡中的作用及影响。方法:第一作者通过检索PubMed、Web of Science、中国知网、万方数据库,检索时限为各数据库建库至2024年3月,中文检索词为“沉默信息调节因子,沉默信息调节因子1,沉默信息调节因子2,沉默信息调节因子3,沉默信息调节因子4,沉默信息调节因子5,沉默信息调节因子6,沉默信息调节因子7,细胞焦亡”,英文检索词为“Sirtuins,Sirtuin1,Sirtuin2,Sirtuin3,Sirtuin4,Sirtuin5,Sirtuin6,Sirtuin7,pyroptosis”,最后纳入71篇文献进行综述。结果与结论:①沉默信息调节因子家族均参与了对细胞焦亡的调控;②过表达沉默信息调节因子1、沉默信息调节因子4可通过多种通路抑制细胞焦亡,从而缓解细胞焦亡对机体的损害;③沉默信息调节因子3除了影响细胞焦亡经典通路外,还能通过增强线粒体活性氧的清除能力、有丝分裂来抑制细胞焦亡;④沉默信息调节因子5参与细胞内代谢和能量平衡的调节,包括能量的摄入、储存和消耗;⑤沉默信息调节因子6既能通过多种通路影响细胞焦亡,还能影响巨噬细胞M1极化、活性氧的生成以及细胞焦亡相关因子消皮素D的裂解以抑制细胞焦亡;⑥过表达沉默信息调节因子7可抑制细胞焦亡;⑦沉默信息调节因子2与其他家族成员不同,其被敲降后才可抑制细胞焦亡,但报道较少,需要更为深入与全面的研究。BACKGROUND:Unlike non-inflammatory cell apoptosis,pyroptosis is a form of inflammatory cell death,characterized by membrane integrity disruption and release of pro-inflammatory intracellular substances.Thus,it is associated with various diseases.The sirtuin family is a group of histone deacetylases dependent on nicotinamide adenine dinucleotide.In addition to deacetylation,it also possesses other enzymatic activities such as desuccinylation,demalonylation,adenosine diphosphate-ribosylation and playing crucial roles in the regulation of pyroptosis.OBJECTIVE:To review the role of the sirtuins in pyroptosis.METHODS:The first author conducted a search on PubMed,Web of Science,CNKI,and WanFang Data from inception to March 2024,using the Chinese and English search terms“Sirtuins,Sirtuin1,Sirtuin2,Sirtuin3,Sirtuin4,Sirtuin5,Sirtuin6,Sirtuin7,pyroptosis”,resulting in the inclusion of 71 articles.RESULTS AND CONCLUSION:(1)The sirtuin family all participates in the regulation of pyroptosis.(2)Overexpression of sirtuin1 and sirtuin4 can inhibit pyroptosis through various pathways,thus alleviating the damage caused by pyroptosis to the organism.(3)In addition to affecting the classical pathway of pyroptosis,sirtuin3 can also inhibit pyroptosis by enhancing mitochondrial reactive oxygen species scavenging capacity and mitosis.(4)Sirtuin5 is involved in the regulation of intracellular metabolism and energy balance,including energy intake,storage,and consumption.(5)Sirtuin6 can influence pyroptosis through various pathways and also affect macrophage M1 polarization,generation of reactive oxygen species,and cleavage of pyroptosis-related factor sclerotin D to inhibit pyroptosis.(6)Overexpression of sirtuin7 can suppress pyroptosis.(7)Sirtuin2,unlike other family members,can restrain pyroptosis only after knockdown,but there are fewer reports,requiring more in-depth and comprehensive research.
