摘要:
目的:建立小鼠单侧输尿管梗阻(UUO)模型,探讨扶肾降浊方对UUO小鼠的疗效及作用机制。方法:建立C57BL/6肾纤维化小鼠模型,将小鼠24只,随机分为对照组、模型组、中药组、西药组,每组6只,术后第2天开始,每天给药1次,中药组给予扶肾降浊方灌胃给药,西药组给予贝那普利灌胃给药,对照组和模型组给予等体积生理盐水灌胃,于第14天剖杀。HE和Masson染色评价纤维化改变,采用Western blotting技术检测肾纤维化标志蛋白Ⅰ型胶原蛋白(Collagen-Ⅰ)、α-平滑肌肌动蛋白(α-SMA),自噬相关蛋白自噬接头蛋白(P62)、微管相关蛋白1A/1B轻链3β(LC3B)以及凋亡相关蛋白细胞淋巴瘤/白血病-2蛋白(Bcl-2)、Bcl-2关联X蛋白(Bax)和切割形式的半胱天冬酶-3蛋白(Cleaved Caspase-3)的表达水平;同时通过RT-qPCR检测Collagen-Ⅰ、α-SMA、P62、Bcl-2和Bax的mRNA表达变化。结果:与对照组相比,模型组小鼠肾脏中出现明显肾脏纤维化改变(t=9.97,P<0.000 1)。与模型组相比,中药组和西药组小鼠肾纤维化程度减轻(t=3.31、4.09,均P<0.05)。与对照组相比,模型组Collagen-1、α-SMA蛋白表达升高(t=7.86、6.46,均P<0.001),转录水平也升高(t=4.52、6.20,均P<0.01),与模型组相比,中药组和西药组Collagen-Ⅰ、α-SMA蛋白表达降低(t=4.25、6.15、3.36、3.60,均P<0.05),转录水平也降低(t=3.31、3.72、4.17、5.07,均P<0.05)。与对照组相比,模型组自噬指标P62蛋白表达和转录水平均降低(t=16.11、8.86,均P<0.001),与模型组相比,中药组和西药组P62蛋白表达和转录水平均升高(t=3.96、5.80、6.30、6.23,均P<0.05)。与对照组相比,模型组自噬标志物LC3B-Ⅱ蛋白表达升高(t=4.09,P<0.05),与模型组相比,中药组和西药组LC3B-Ⅱ蛋白表达降低(t=4.15、3.98,均P<0.05)。与对照组相比,模型组促凋亡蛋白Bax和抗凋亡蛋白Bcl-2的蛋白表达比值(Bax/Bcl-2)升高(t=5.83,P<0.01),与模型组相比,中药组和西药组Bax/Bcl-2蛋白表达比值降低(t=4.97、4.67,均P<0.01)。与对照组相比,模型组Bax转录水平升高(t=6.87,P<0.001),Bcl-2转录水平降低(t=19.15,P<0.000 1),与模型组相比,中药组和西药组Bax转录水平降低(t=3.31、4.23,均P<0.05),Bcl-2转录水平升高(t=4.03、3.27,均P<0.05)。与对照组相比,模型组Cleaved Caspase-3表达升高(t=7.12,P<0.001),与模型组相比,中药组、西药组Cleaved Caspase-3蛋白表达降低(t=3.20、5.51,均P<0.05)。结论:扶肾降浊方能够显著改善肾功能,减轻肾纤维化程度。其作用机制可能与抑制自噬及凋亡有关。
Abstract:
Objective: To establish a mouse model of unilateral ureteral obstruction (UUO) and investigate the therapeutic effect of the Fushen Jiangzhuo Formula (FJF) on UUO mice and its underlying mechanism. Methods: A renal fibrosis model was established in 24 C57BL/6 mice, which were randomly divided into four groups (n=6 per group): control group, model group, traditional Chinese medicine (TCM) group (administered FJF by gavage), and Western medicine group (administered benazepril by gavage). Daily administration started on the second day after surgery. The control and model groups received an equal volume of normal saline. All mice were sacrificed on day 14. Fibrosis was assessed using HE and Masson staining. Western blotting was used to detect the protein expression levels of fibrosis markers [type Ⅰ collagen (Collagen-Ⅰ), α-smooth muscle actin (α-SMA)], autophagy-related proteins [autophagy adaptor protein (P62), microtubule-associated protein 1A/1B-light chain 3B (LC3B)], and apoptosis-related proteins [lymphoma/leukemia-2 (Bcl-2), Bcl-2-associated X protein (Bax), and cleaved form of caspase-3 protein (Cleaved Caspase-3)]. RT-qPCR was used to measure the mRNA expression changes of Collagen-Ⅰ, α-SMA, P62, Bcl-2, and Bax. Results: Compared with the control group, the model group showed significant renal fibrosis (t=9.97, P<0.000 1). Compared with the model group, both the TCM and Western medicine groups exhibited reduced renal fibrosis (t=3.31, 4.09, both P<0.05). Protein expression of Collagen-Ⅰ and α-SMA was increased in the model group versus controls (t=7.86, 6.46, both P<0.001), as were their mRNA levels (t=4.52, 6.20, both P<0.01). Compared with the model group, both treatment groups showed decreased Collagen-Ⅰ and α-SMA protein expression (t=4.25, 6.15, 3.36, 3.60, all P<0.05) and mRNA levels (t=3.31, 3.72, 4.17, 5.07, all P<0.05). The autophagy indicator P62 was decreased in the model group at both protein (t=16.11, P<0.001) and mRNA (t=8.86, P<0.001) levels co-mpared to controls. Both treatment groups showed increased P62 protein (t=3.96, 5.80, both P<0.05) and mRNA (t=6.30, 6.23, both P<0.05) expression versus the model group. The autophagy marker LC3B-Ⅱ protein expression was higher in the model group (t=4.09, P<0.05) and was reduced in both treatment groups (t=4.15, 3.98, both P<0.05). The Bax/Bcl-2 protein ratio was increased in the model group (t=5.83, P<0.01) and decreased in both treatment groups (t=4.97, 4.67, both P<0.01). Compatred with control groups, Bax mRNA was elevated (t=6.87, P<0.001) while Bcl-2 mRNA was reduced (t=19.15, P<0.000 1) in model group. Both treatments reversed these changes, lowering Bax mRNA (t=3.31, 4.23, both P<0.05) and raising Bcl-2 mRNA (t=4.03, 3.27, both P<0.05). Cleaved Caspase-3 protein was upregulated in model group (t=7.12, P<0.001) and downregulated in both treatment groups (t=3.20, 5.51, both P<0.05). Conclusion: The FJF can significantly improve renal function and alleviate the degree of renal fibrosis. Its mechanism may be related to the inhibition of autophagy and apoptosis.
