Aicardi-Goutieres syndrome(AGS)is a systemic inflammatory disorder caused by mutations in any one of the nine different genes,whose deficiency provokes a type I(interferon)IFN response probably central to pathogenesis.^(1) ADAR1,one of the genes mutated in AGS(AGS6),encodes for an enzyme that belongs to the ADAR family(ADAR1,ADAR2,and ADAR3)that catalyzes the conversion of adenosine to inosine within double-stranded RNAs(dsRNAs)(RNA editing A-to-1).

目的:探讨高强度间歇训练(high-intensity interval training,HIIT)对高脂喂养的载脂蛋白E(ApoE)敲除(Apo^(E-/-))小鼠骨骼肌氧化应激的改善作用以及肌肉因子β-氨基异丁酸(β-aminoisobutyic acid,BAIBA)在其中的可能调节机制。方法:9周龄健康雄性C57Bl/6J小鼠和Apo^(E-/-)小鼠分别喂食标准和高脂饲料,其中C57Bl/6J小鼠为基线对照组(WT,n=6),Apo^(E-/-)小鼠经高脂饲料喂养12周后随机分为Apo^(E-/-)安静组(Apo^(E-/-),n=10)和Apo^(E-/-)高强度间歇训练组(Apo^(E-/-)HIIT,n=10),Apo^(E-/-)HIIT组进行6周HIIT,WT和Apo^(E-/-)组在笼中自由活动。最后一次运动后48 h取小鼠两侧腿部腓肠肌进行氧化损伤、抗氧化及BAIBA生成相关指标的检测。随后采用l-BAIBA预孵育C2C12细胞,后用过氧化氢(H_(2)O_(2))诱导氧化应激,结合干预条件随机分为Control、H_(2)O_(2)和l-BAIBA+H_(2)O_(2)组。相差显微镜观察细胞形态,并检测细胞ROS水平和Nrf2介导的抗氧化通路的相关指标。结果:1)与WT组相比,Apo^(E-/-)组小鼠骨骼肌氧化损伤相关的4-HNE修饰蛋白、蛋白质羰基含量和ROS水平显著升高,而抗氧化相关的p-Nrf2蛋白表达和GSH含量显著降低;而与Apo^(E-/-)组相比,Apo^(E-/-)HIIT组小鼠骨骼肌4-HNE修饰蛋白和蛋白质羰基含量明显降低,p-Nrf2蛋白表达和GSH含量明显升高。2)Apo^(E-/-)HIIT组小鼠骨骼肌生成BAIBA的相关酶基因Acads和Hadha mRNA的表达水平显著高于Apo^(E-/-)组。3)与Control组相比,H_(2)O_(2)干预后C2C12细胞明显皱缩,活细胞数量降低,ROS水平显著增加;而与H_(2)O_(2)组相比,l-BAIBA+H_(2)O_(2)组活细胞数量增加,形态较饱满,ROS水平明显降低。4)与Control组相比,H_(2)O_(2)显著降低了细胞Nrf2、p-Nrf2及其介导的抗氧化酶SOD1、NQO1和CAT蛋白以及合成GSH的相关酶基因Gss、Gsr和Gclm mRNA的表达水平,并显著降低了细胞GSH含量;而l-BAIBA+H_(2)O_(2)组较H_(2)O_(2)组则显著增加了p-Nrf2、SOD1和NQO1蛋白以及Gss、Gsr、Gclc和Gclm mRNA的表达量,同时细胞GSH含量也显著增加。结论:6周HIIT降低了高脂喂养的Apo^(E-/-)小鼠骨骼肌的氧化损伤,其中肌肉因子BAIBA对Nrf2介导的抗氧化信号的激活可能起着一定的作用。
