摘要:

目的 探讨人参醇提取物(GEE)通过维持氧化还原平衡改善老年果蝇模型睡眠的作用,并阐明其相关作用机制。 方法 随机选取32只7 d龄雄性黑腹果蝇作为年轻组,另选64只35 d龄雄性黑腹果蝇随机分为老年组和GEE组,每组32只。培养基给药7 d后利用DAM2果蝇行为学分析系统分析各组果蝇总睡眠时长、日间睡眠时长、夜间睡眠时长、关灯后4 h内睡眠时长(ZT0-4睡眠时长)、深睡眠时长、睡眠发生次数和睡眠片段化等睡眠参数以及总自主活动次数、日间自主活动次数和夜间自主活动量等活动参数。利用基于双向荧光差异凝胶电泳(2D-DIGE)和基质辅助激光解析电离飞行时间质谱(MALDI-TOF-MS)的蛋白质组学方法对果蝇脑组织中差异表达蛋白进行筛选、鉴定及功能分析。利用试剂盒法检测各组果蝇脑组织中超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和谷胱甘肽过氧化物酶(GSH-Px)活性及脂质过氧化产物(MDA)水平。 结果 与年轻组比较,老年组果蝇总睡眠时长、日间睡眠时长和夜间睡眠时长缩短(P<0.05或P<0.01);与老年组比较,GEE组果蝇总睡眠时长、日间睡眠时长和夜间睡眠时长明显延长(P<0.01)。与年轻组比较,老年组果蝇ZT0-4睡眠时长、深睡眠时长和睡眠片段化缩短(P<0.05或P<0.01),睡眠节律振幅缩短;与老年组比较,GEE组果蝇ZT0-4睡眠时长、深睡眠时长和睡眠片段化延长(P<0.01),睡眠节律振幅提高。2D-DIGE电泳图谱中共筛选出47个差异表达蛋白,与年轻组比较,老年组表达下调;与老年组比较,GEE组蛋白表达上调,差异表达蛋白主要包括谷胱甘肽S转移酶、过氧化物氧还蛋白1和二氢硫辛酸脱氢酶等调控氧化还原平衡相关的蛋白。与年轻组比较,老年组果蝇脑组织中SOD、CAT和GSH-Px活性降低(P<0.05或P<0.01),MDA水平升高(P<0.01);与老年组比较,GEE组果蝇脑组织中SOD、CAT和GSH-Px活性升高(P<0.05或P<0.01),MDA水平降低(P<0.05)。 结论 GEE对老年果蝇睡眠具有改善作用,其机制可能与提高抗氧化酶活性、抑制MDA积累和维持氧化还原平衡有关。

Abstract:

Objective To investigate the impact of ginseng alcohol extract (GEE) on improving sleep quality in the aged Drosophila model by regulating the redox balance, and to elucidate its associated mechanism. Methods Thirty-two male drosophila melanogaster (7-days-old) were randomly selected as young group, while 64 male Drosophila melanogaster flies (35-days-old) were randomly assigned to aged model group and GEE group. The sleep parameters, including total sleep duration, daytime sleep duration, night sleep duration, 0-4 h of sleep duration after lights off (ZT0-4 sleep duration), deep sleep duration, sleep episodetimes, sleep fragmentation, and the activity parameters such as the total number of locomotor activity daytime locomotor activity amount and nighttime locomotor activity amount were analyzed using the DAM2 Drosophila behavioral analysis system 7 d after medium administration. The differentially expressed proteins in drosophila brain tissue were screened, identified, and functionally analyzed using two-dimensional fluorescence difference gel electrophoresis(2D-DIGE) and matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF/TOF-MS) proteomic methods. The activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) and the levels of lipid peroxidation product (MDA) in brain tissue of the drosophila were determined using assay kits. Results Compared with young group, the total sleep duration daytime sleep duration and night sleep cluration of the drosophila in agaed group were decreased(P<0.01 or P<0.05); and the sleep rhythm amplitude was shortened. Compared with aged group, the total sleep duration and daytime and nighttime sleep durations of the drosphila in GEE group were lengthened (P<0.01). Compared with young group, the ZT0-4 sleep duration deep sleep duration and sleep fragment of the drosophila in aged group were decreased (P<0.01 or P<0.05), and the sleep rhythm amplitude was shortened. Compared with young group, the ZT0-4 sleep duration, deep sleep duration, and single sleep fragment of the drosphila in GEE group were significantly prolonged (P<0.01), and the sleep amplitude was increased. A total of 47 differentially expressed proteins were selected in the 2D-DIGE electrophoretic mapping. Compared with young group, the expressions of 47 differentially expressed protein sites in aged group were down-regulated mainly including glutathione S-transferase, peroxiredoxin 1 and dihydrolipoic dehydrogenase, which were related to redox balance. Compared with young group, the activities of SOD, CAT and GSH-Px in brain tissue of the drosophila in aged group were decreased (P<0.05 or P<0.01), and the level of MDA was increased (P<0.01); compared with aged group, the activities of SOD, CAT and GSH-Px in brain tissue of the drosphila in GEE group were increased (P<0.05 or P<0.01), and the MDA level was decreased (P<0.05). Conclusion GEE has improvement effect on the sleep quality of aged drosophila, and its possible mechanism may be related to upregulating the activities of antioxidant enzymes, inhibiting the accumulation of lipid peroxidation products, and maintaining redox balance.
