Huangqi-Danshen Decoction Ameliorates Adenine-Induced Chronic Kidney Disease by Modulating Mitochondrial Dynamics.

ABSTRACT: Chronic kidney disease (CKD) is a leading public health problem with high morbidity and mortality. However, the therapies remain limited. Traditional Chinese medicine (TCM) has been used for treating kidney disease for thousands of years and is an effective alternative treatment for CKD patients in China and other Asian countries. In the present study, we aimed to investigate the effect and mechanism of Huangqi-Danshen decoction (HDD), a TCM herbal decoction, on treating CKD. CKD rat model was induced by adding 0.75% adenine to the diet for 4 weeks. HDD extract was administrated orally to CKD rats at the dose of 4.7 g/kg/d for consecutive 4 weeks in adenine-induced CKD rats. Kidney function was evaluated by the levels of serum creatinine (Scr) and blood urea nitrogen (BUN). The pathological changes of kidney tissues were observed by periodic acid-Schiff (PAS) and Masson's trichrome staining. The proteins expression of renal fibrosis and mitochondrial dynamics were determined and quantified by Western blot analysis. CKD rats showed obvious decline in renal function as evidenced by increased levels of Scr and BUN, which were blunted by HDD treatment. HDD could also improve tubular atrophy and interstitial fibrosis of CKD rats. Moreover, HDD downregulated fibronectin, type IV collagen, and ?-smooth muscle actin expression in CKD rats. Furthermore, mitochondrial dynamics was disturbed in CKD rats, which manifested as increased mitochondrial fission and decreased mitochondrial fusion. HDD treatment restored mitochondrial dynamics in CKD rats by repressing dynamin-related protein 1 and Mid 49/51 expression, promoting mitofusin 2 expression, and suppressing optic atrophy 1 proteolysis. In conclusion, HDD could significantly retard CKD progression through modulating mitochondrial dynamics.

Project description:Purpose: Our study clarifies the mechanism of Huangqi decoction (HQD) against DKD in diabetic db/db mice. Methods: Eight-week-old male diabetic db/db mice were randomly divided into four groups: Model (1% CMC), HQD-L (0.12 g/kg), HQD-M (0.36 g/kg), and HQD-H (1.08 g/kg) groups. Non-diabetic db/m mice were used as a control group. These mice received HQD treatment for 8 weeks continuously. After 8 weeks of feeding, kidneys were harvested to observe the kidney function, pathological changes, micro-assay study, and the protein expression levels. Results: HQD treatment improved the albumin/creatine ratio (ACR) and 24 h urinary albumin, prevented the pathological phenotypes of increased glomerular volume, widened mesangial areas, the proliferation of mesangial matrix, the disappearance of foot processes, the decreased expression of nephrin and the number of podocytes. The expression profile chips were assessed to reveal the global transcriptional response and predict related functions, diseases and pathways. To verify this, we found that HQD treatment activated the protein expressions of BMP1, BMP7, BMPR2, and active-Rap1 and inhibited Smad1 and phospho-ERK. In addition, HQD could improve lipid deposition in the kidneys of db/db mice. Conclusion: HQD prevents the progression of DKD in db/db mice by regulating the transcription of BMPs and their downstream target genes, inhibiting the phosphorylation of ERK and Smad1 by promoting the binding of Rap1 to GTP and regulating the lipid metabolism dysfunction. These provide a new idea for the treatment of DKD. Overall, HQD had a significant protective effect against DKD. This may be related to the fact that HQD promotes the transcription of BMPs and their downstream target genes by upregulating BMPR-II and regulates the phosphorylation of ERK and Smad by promoting the binding of Rap1 to GTP. In addition, HQD also has a noticeable role in regulating lipid metabolism dysfunction in DKD, which provides a new idea for future research on HQD.

Project description:IntroductionNon-alcoholic fatty liver disease (NAFLD) is a multifactorial disease. As a clinical empirical prescription of traditional Chinese medicine, Qushi Huayu decoction (QHD) has attracted considerable attention for its advantages in multi-target treatment of NAFLD. However, the intervention mechanism of QHD on abnormal lipid levels and gut microbiota in NAFLD has not been reported.MethodsTherefore, we verified the therapeutic effect of QHD on high-fat diet (HFD)-induced NAFLD in rats by physiological parameters and histopathological examination. In addition, studies on gut microbiota and serum lipidomics based on 16S rRNA sequencing and ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS) were conducted to elucidate the therapeutic mechanism of NAFLD in QHD.ResultsThe changes in gut microbiota in NAFLD rats are mainly reflected in their diversity and composition, while QHD treated rats restored these changes. The genera Blautia, Lactobacillus, Allobaculum, Lachnoclostridium and Bacteroides were predominant in the NAFLD group, whereas, Turicibacter, Blautia, Sporosarcina, Romboutsia, Clostridium_sensu_stricto_1, Allobaculum, and Psychrobacter were predominant in the NAFLD+QHD group. Lipid subclasses, including diacylglycerol (DG), triglycerides (TG), phosphatidylethanolamine (PE), phosphatidylcholine (PC), phosphatidic acid (PA), phosphatidylserine (PS), lysophosphatidylinositol (LPI), and phosphatidylglycerol (PG), were significantly different between the NAFLD and the control groups, while QHD treatment significantly altered the levels of DG, TG, PA, lysophosphatidylcholine (LPC), lysophosphatidylethanolamine (LPE), and platelet activating factor (PAF). Finally, Spearman's correlation analysis showed that NAFLD related differential lipid molecules were mainly associated with the genera of Bacteroides, Blautia, Lachnoclostridium, Clostridium_sensu_stricto_1, and Turicibacter, which were also significantly correlated with the biological parameters of NAFLD.DiscussionTaken together, QHD may exert beneficial effects by regulating the gut microbiota and thus intervening in serum lipids.
