Polycystic ovarian syndrome (PCOS) with wide-range prevalence, affecting 5-18% of females of reproductive age, and its substantive role as a primary etiological factor in anovulatory infertility, with up to 80% of such cases attributed to this syndrome having particular significance.
The current research delineates the outcomes of a meticulous inquiry into the efficacy of Fagonia indica-coated chitosan nanoparticles (FICNPs) in ameliorating the prevalent and clinically consequential PCOS in female Wistar rats.
FICNPs were synthesized by using a methanolic extract of F. indica and chitosan via the ion gelatin method. The nuanced interplay of hormonal profiles, ovarian histology, and miRNA expression in response to FICNPs intervention was investigated. Notable findings include an obvious decrease in luteinizing (LH) and testosterone hormone levels with high-dose FICNPs-treated subjects (100 mg/kg) compared to their untreated counterparts.
Follicle-stimulating hormone (FSH) and prolactin levels were markedly decreased in the untreated PCOS rat models, whereas, histopathological examination revealed augmented oocyte diameters in FICNP-treated rats, suggesting pronounced improvements in ovarian morphogenesis and follicular maturation. Additionally, real-time quantitative PCR analysis revealed disparate miRNA expression profiles, prominently implicating rno-miR-30c-2-3p, rno-miR-146b-5p, rno-miR-486, and rno-miR-3586-3p in the therapeutic efficacy of FICNPs. Notably, the progeny of FICNPs-treated subjects (F1 generation) showed normalized ovulatory activity, substantiating the sustained therapeutic potential of FICNPs.
Collectively, these findings underscore the auspicious promise of FICNPs as a paradigm-shifting therapeutic modality for mitigating the complex pathophysiology of PCOS, thereby addressing its formidable prevalence and clinical import, with the potential to surpass conventional pharmacotherapy modalities.
多囊卵巢综合征(PCOS)患病率广泛,影响5% - 18%的育龄女性,并且作为无排卵性不孕症的主要病因因素,高达80%的此类病例归因于该综合征,具有特殊意义。
当前研究描述了对印度法氏龙葵包被的壳聚糖纳米颗粒(FICNPs)改善雌性Wistar大鼠中普遍且具有临床后果的PCOS疗效进行细致探究的结果。
通过离子凝胶法,使用印度法氏龙葵的甲醇提取物和壳聚糖合成FICNPs。研究了FICNPs干预后激素谱、卵巢组织学和miRNA表达之间的细微相互作用。显著发现包括,与未治疗的对照组相比,高剂量FICNPs治疗组(100 mg/kg)的黄体生成素(LH)和睾酮激素水平明显降低。
未治疗的PCOS大鼠模型中促卵泡激素(FSH)和催乳素水平显著降低,而组织病理学检查显示FICNP治疗的大鼠卵母细胞直径增大,表明卵巢形态发生和卵泡成熟有明显改善。此外,实时定量PCR分析显示了不同的miRNA表达谱,突出表明rno-miR-30c-2-3p、rno-miR-146b-5p、rno-miR-486和rno-miR-3586-3p与FICNPs的治疗效果有关。值得注意的是,FICNPs治疗组的后代(F1代)排卵活动正常化,证实了FICNPs具有持续的治疗潜力。
总体而言,这些发现强调了FICNPs作为一种变革性治疗方式减轻PCOS复杂病理生理学的良好前景,从而解决其普遍存在的问题和临床重要性,有可能超越传统药物治疗方式。
