中文摘要: 为探究黑果枸杞提取物(Lycium ruthenicum Murr. Extract,LRE)对人卵巢颗粒细胞(Simian virus 40 largeTantigen immortalized human ovarian granulosalutein cells, SVOG)氧化损伤的改善作用及相关机制,采用2,2'-偶氮二异丁基脒二盐酸盐(2,2'-Azobis(2-amidinopropane) dihydrochloride,AAPH)诱导SVOG细胞建立氧化应激损伤模型,并设置不同浓度LRE(0.5、1、2 mg/mL)干预组。通过检测细胞活性、活性氧(Reactive Oxygen Species,ROS)、丙二醛(Malondialdehyde,MDA)含量、超氧化物歧化酶(Superoxide Dismutase,SOD)活力、线粒体膜电位(Mitochondrial membrane potential,MMP)以及抗缪勒氏管激素(Anti-Müllerian Hormone,AMH)分泌水平,系统评价LRE对SVOG的保护作用。实验结果显示,2 mg/mL LRE能显著提升AAPH刺激后SVOG细胞的存活率(P< 0.01),有效抑制细胞内ROS生成与MDA的积累(P< 0.01),并增强SOD酶活力(P< 0.01)。同时,LRE处理显著恢复了受损细胞的MMP(P< 0.01)并促进AMH分泌(P< 0.01),表明其可通过改善线粒体功能与激素分泌缓解氧化应激损伤。以上结果说明,黑果枸杞提取物对AAPH诱导的卵巢颗粒细胞氧化损伤具有明显的保护作用,其机制可能与增强抗氧化防御、稳定线粒体功能及维持细胞正常内分泌功能有关。该结果为黑果枸杞在女性生殖健康领域的应用提供了实验依据,对其进一步开发具有参考价值。
Abstract:To investigate the protective effect and underlying mechanism of Lycium ruthenicum Murr. Extract (LRE) against oxidative damage in human ovarian granulosa Simian virus 40 largeTantigen immortalized human ovarian granulosalutein cells (SVOG), an oxidativestressinjured cell model was established by challenging SVOG cells with 2,2'-Azobis(2amidinopropane) dihydrochloride (AAPH). Intervention groups were treated with different concentrations of LRE (0.5, 1, 2?mg/mL). Cell viability, intracellular reactive oxygen species (ROS) level, malondialdehyde (MDA) content, superoxide dismutase (SOD) activity, mitochondrial membrane potential (MMP), and antiMüllerian hormone (AMH) secretion were determined to systematically evaluate the cytoprotective effects of LRE on SVOG cells. The results demonstrated that 2?mg/mL LRE markedly improved the survival rate of AAPHexposed SVOG cells (P?
