摘要:
背景: 糖尿病性肾上腺病(DN)是最常见的微血管并发症之一。人参皂苷RG1(RG1)是从Panax Ginseng提取的重要活性成分。这项研究旨在研究RG1在DN模型中的作用和分子机制。
Results: We found that Rg1 treatment markedly elevated the survival rates of HG-induced HBZY-1 cells and reduced apoptosis induced by HG. Rg1 treatment attenuated the HG-induced inflammatory response by decreasing the high levels of TNF-α, IL-1β和IL-6。此外,RG1治疗通过减少ROS产生,丙二醛(MDA)和乳酸脱氢酶(LDH)的积累并增加了超氧化物歧化酶(SOD)(SOD)和谷胱甘肽(GSH-PX)的活性,从而缓解了HG诱导的氧化应激。在RG1(50 mg/kg/d)处理后,严重的肾小球增生,肾小球萎缩,肾小管皮细胞剥落,地下膜暴露,间质性水肿和炎性细胞的细胞质浸润在DN大鼠中减轻了。用RG1(50 mg/kg/d)处理的DN大鼠模型显示出良好的抗炎和抗氧化活性。 Rg1 treatment also increased the levels of the phosphorylation of PI3K (p-PI3K) and AKT (p-AKT) and promoted the transfer of FOXO3 from the nucleus to the cytoplasmand.
Conclusions: Rg1 exhibited protective effects on DN-induced inflammatory responses and通过调节PI3K/AKT/FOXO3途径的氧化应激。这结果表明RG1可能是DN治疗的潜在治疗剂。
