Follicular granulosa cells (GCs) form an important association with follicle’s survival and health that determines ovulation. Apoptosis induction in GCs leads to follicular atresia and infertility problems. The present study aims at assessing the ultrastructural toxicity of methoxychlor (MXC), an organochlorine insecticide and reproductive toxin, on structural aspects of GCs owing to its potential for inducing apoptosis and the ameliorating potential of N-acetyl-L-cysteine (NAC) in this toxicity. The ultrastructural morphology revealed MXC induced degenerative changes in GCs like loss of cellular junction complexes and membrane integrity; nuclear abnormalities like occurrence of condensed and marginated chromatin, crescent shaped or blebbed nucleus; presence of disrupted mitochondria with disrupted cristae, vacuolization, empty spaces, large number of homogenous lipid droplets and extensive network of rough endoplasmic reticulum and several cytoplasmic processes at various doses of MXC with maximum degeneration observed at 100 μg/ml. NAC supplementation reduced the observed apoptotic characteristics of GCs with most significant changes at 5- and 10 mM concentration. Thus, it is evident that MXC acts as an apoptotic inducer in GCs that influences the quality of antral follicles in mammals; however, NAC, with its anti-oxidative and anti-inflammatory properties, turns out to be a potential therapeutic and anti-apoptotic agent against MXC toxicity.

N-乙酰-l-半胱氨酸对甲氧氯引起的山羊窦卵泡颗粒细胞结构特征调节的改善潜力

卵泡颗粒细胞 (GC) 与决定排卵的卵泡存活和健康形成重要关联。GC 中的细胞凋亡诱导导致卵泡闭锁和不育问题。本研究旨在评估甲氧氯 (MXC)(一种有机氯杀虫剂和生殖毒素)对 GCs 结构方面的超微结构毒性,因为它具有诱导细胞凋亡的潜力和 N-乙酰-L-半胱氨酸(NAC)的改善潜力。这种毒性。超微结构形态显示 MXC 诱导 GC 的退行性变化,如细胞连接复合物和膜完整性的丧失;核异常,如出现浓缩和边缘的染色质、新月形或带泡的核;存在被破坏的线粒体,嵴被破坏,空泡化,空的空间,在不同剂量的 MXC 下,大量均匀的脂滴和广泛的粗面内质网网络和几个细胞质突起,在 100 μg/ml 时观察到最大变性。补充 NAC 降低了观察到的 GC 的凋亡特征,在 5 和 10 mM 浓度下发生了最显着的变化。因此,很明显 MXC 在 GC 中充当凋亡诱导剂,影响哺乳动物的窦卵泡质量。然而,具有抗氧化和抗炎特性的 NAC 被证明是一种针对 MXC 毒性的潜在治疗剂和抗凋亡剂。补充 NAC 降低了观察到的 GC 的凋亡特征,在 5 和 10 mM 浓度下发生了最显着的变化。因此,很明显 MXC 在 GC 中充当凋亡诱导剂,影响哺乳动物的窦卵泡质量。然而,具有抗氧化和抗炎特性的 NAC 被证明是一种针对 MXC 毒性的潜在治疗剂和抗凋亡剂。补充 NAC 降低了观察到的 GC 的凋亡特征,在 5 和 10 mM 浓度下发生了最显着的变化。因此,很明显 MXC 在 GC 中充当凋亡诱导剂,影响哺乳动物的窦卵泡质量。然而,具有抗氧化和抗炎特性的 NAC 被证明是一种潜在的治疗和抗 MXC 毒性的抗凋亡剂。
