摘要:
目的:探讨间歇性热量限制对辐射所致小鼠认知功能障碍的作用及可能机制。方法:将36只7周龄c57BL/6J雄性小鼠按随机数表法分为假辐射+随意饮食组(sham-irradiation and ad libitum,Sham-AL)、辐射+随意饮食组(irradiation and ad libitum,IR-AL)、辐射+间歇性热量限制组(irradiation and intermittent fasting,IR-IF),每组12只。采用新旧事物识别实验检测各组小鼠认知功能;Western blot分别检测小鼠海马自噬相关基因5(ATG5)、微管相关蛋白1轻链3-II(LC3II)、自噬接头蛋白P62、线粒体阴离子通道蛋白1(VDAC1)、白介素1(IL-1β)、突触囊泡膜蛋白(SYP)、突触蛋白1(SYN-1)、突触后致密物-95(PSD9...
摘要(英文):
Objective To investigate the protective effect of intermittent fasting on radiation-induced cognitive impairment and the possible underlying mechanism. Methods A total of 36 male 7-week old C.57BL/6J mice were divided into Sham-irradiation and ad libitum (Sham-AL) group, irradiation and ad libitum (IR-AL) group, and irradiation add intermittent fasting (IR-IF) group according to the random number table method, with 12 mice in each group. The cognitive function of mice was assessed by novel object recognition task. The expressions of autophagy g...
