摘要/Abstract

摘要： 目的探讨泽泻提取物(zexie)通过调控miR-4417/TGF-β通路对妊娠期糖尿病大鼠的治疗效果及作用机制。方法将妊娠期糖尿病(GDM)模型大鼠随机分为糖尿病组、泽泻低、中、高剂量组和胰岛素组、miR-NC组、miR-4417 mimic组、miR-4417 inhibitor组、泽泻+miR-4417 mimic+LY364947组,每组12只,另选12只正常妊娠大鼠为正常组。HE染色检测大鼠胰岛组织病理损伤。RT-qPCR 和Western blot检测组织中各因子mRNA和蛋白质水平。结果与糖尿病组相比,泽泻低、中、高和胰岛素组的血糖、血脂、氧化应激指标及胰岛组织病理损伤显著改善(P＜0.05),miR-4417和Tgf-β mRNA显著降低(P＜0.05),其中泽泻高剂量组变化最为显著(P＜0.05)。与miR-NC组相比,miR-4417 mimic组中TGF-β蛋白明显升高(P＜0.05),miR-4417 inhibitor 组明显降低(P＜0.05)。与糖尿病组相比,泽泻组、泽泻+miR-4417 mimic组、泽泻+miR-4417 mimic+ LY364947组的氧化应激和ROS 累积显著降低(P＜0.05)。与miR-4417 mimic组比较,泽泻+miR-4417 mimic组氧化应激和活性氧(ROS)累积显著降低(P＜0.05)。泽泻组与泽泻+miR-4417 mimic+ LY364947组比较差异无统计学意义。结论泽泻能够改善大鼠的血糖和脂质水平,降低胰岛素抵抗,控制氧化应激及氧化损伤的能力,其机制可能与miR-4417/TGF-β通路的调节有关。

Abstract: Objective To investigate the therapeutic effects and mechanisms of Alisma orientale extract(zexie) on gestational diabetes mellitus (GDM) rats by regulating the miR-4417/TGF-β pathway. Methods GDM model rats were randomly divided into a diabetic group, low,medium,high-dose zexie group, insulin group, miR-NC group, miR-4417 mimic group, miR-4417 inhibitor group, and zexie+miR-4417 mimic+LY364947 group, with 12 rats in each group. Additionally, 12 normal pregnant rats served as the control group. Hematoxylin and eosin(HE) staining was used to evaluate pancreatic islet pathology. RT-qPCR and Western blot were employed to measure the mRNA and protein levels of various factors. Results Compared with the diabetic group, the glucose, lipid, oxidative stress indicators, and pancreatic islet pathological damage were significantly improved(P＜0.05) in the low, medium and high-dose zexie groups and the insulin group. The expression levels of miR-4417 and TGF-β mRNA were notably reduced(P＜0.05), with the most significant changes observed in the high-dose zexie group(P＜0.05). Compared with the miR-NC group, the TGF-β protein level was significantly increased(P＜0.05) in the miR-4417 mimic group and decreased(P＜0.05) in the miR-4417 inhibitor group. Compared with the diabetic group, the oxidative stress and reactive oxygen species (ROS) accumulation were significantly lower(P＜0.05) in the zexie, zexie+miR-4417 mimic, and zexie+miR-4417 mimic+LY364947 groups. Compared with the miR-4417 mimic group, the oxidative stress and ROS accumulation were significantly reduced(P＜0.05) in the zexie+miR-4417 mimic group. No significant differences were found between the zexie group and the zexie+miR-4417 mimic + LY364947 group. Conclusions Zexie can improve glucose and lipid levels, reduce insulin resistance, and control oxidative stress and damage in GDM rats, possibly through the regulation of the miR-4417/TGF-β pathway.
