BACKGROUND
The disruption of renal cell homeostasis caused by aging has attracted considerable attention. A traditional Chinese medicine, ginseng, is a potential drug for treating aging-related diseases. The study investigates the effect and mechanism of ginsenoside Rg1, an active component of ginseng, on renal aging and injury.
MATERIALS AND METHODS
The potential targets of ginsenoside Rg1 in relieving renal aging and injury were predicted using network pharmacology. d-Galactose (d-gal) was used to induce aging and mice were randomly divided into six groups: a wild-type control group, a wild-type d-gal group, and a wild-type d-gal with Rg1 group (20 mg/kg/d), a caspase-1 control group, a caspase-1 d-gal group, and a caspase-1 d-gal with Rg1 group ( = 5). The duration of the study was 42 days. The effect of Rg1 was assessed by hematoxylin and eosin and Masson staining, quantitative reverse transcription PCR, enzyme-linked immunosorbent assay, and Western blotting.
RESULTS
Network pharmacology revealed that caspase-1 was one of the crucial targets. experiments, ginsenoside Rg1 treatment resulted in lowered levels of β-Gal, p53, p21, blood urea nitrogen, serum creatinine, malondialdehyde, reactive oxygen species, tumor necrosis factor-α and renal fibrosis, along with a reduction of caspase-1, interleukin-1 and interleukin-18 in mice induced by d-gal. Additionally, knockout of caspase-1 can improve the above indicators and caspase-1 mice treated with Rg1 showed better protective effects in alleviating renal senescence, ameliorating kidney injury, and mitigating inflammation and oxidative stress.
CONCLUSION
The findings in this study provide experimental support for the clinical application of ginsenoside Rg1 in kidney aging. The underlying mechanisms require further experimental validation.
背景
衰老引起的肾细胞内环境稳态破坏已引起广泛关注。中药人参是治疗衰老相关疾病的潜在药物。本研究探讨人参活性成分人参皂苷Rg1对肾脏衰老和损伤的作用及机制。
材料与方法
采用网络药理学预测人参皂苷Rg1缓解肾脏衰老和损伤的潜在靶点。用d-半乳糖(d-gal)诱导衰老,将小鼠随机分为六组:野生型对照组、野生型d-gal组、野生型d-gal加Rg1组(20mg/kg/d)、caspase-1对照组、caspase-1 d-gal组、caspase-1 d-gal加Rg1组(n = 5)。研究持续42天。通过苏木精-伊红染色和Masson染色、定量逆转录PCR、酶联免疫吸附测定和蛋白质免疫印迹法评估Rg1的作用。
结果
网络药理学显示caspase-1是关键靶点之一。实验中,人参皂苷Rg1处理可降低d-gal诱导的小鼠体内β-半乳糖苷酶、p53、p21、血尿素氮、血清肌酐、丙二醛、活性氧、肿瘤坏死因子-α水平及肾纤维化程度,同时降低caspase-1、白细胞介素-1和白细胞介素-18水平。此外,敲除caspase-1可改善上述指标,用Rg1处理的caspase-1基因敲除小鼠在减轻肾脏衰老、改善肾损伤、减轻炎症和氧化应激方面显示出更好的保护作用。
结论
本研究结果为人参皂苷Rg1在肾脏衰老临床应用提供了实验依据。其潜在机制需进一步实验验证。
