摘要(Abstract):
本研究旨在分析体外白藜芦醇对去乙酰化酶SIRT1表达量的影响,探讨去乙酰化酶SIRT1表达量与颗粒细胞凋亡间的相关性。采用qRT-PCR方法进行SIRT1 mRNA分析,Annexin V-FITC细胞凋亡检测试剂盒和流式细胞仪检测猪卵巢颗粒细胞凋亡率。结果表明:培养液中白黎芦醇浓度达到50μmol/L时,处理组颗粒细胞中SIRT1 mRNA表达量极显著高于空白对照组(P<0.01);与颗粒细胞中SIRT1表达量规律相同,随着白黎芦醇浓度的升高,颗粒细胞活力逐渐降低,凋亡率逐渐升高。综合分析,白藜芦醇可诱导猪卵巢颗粒细胞中去乙酰化酶SIRT1的表达,加速猪卵巢颗粒细胞凋亡,SIRT1表达与猪卵巢颗粒细胞凋亡存在一定相关性。
