Project description:Diabetic rats changes gene exprssion in Qishen Yiqi Dripping Pill-treated rats kidney Diabetic nephropathy (DN) is a severe microvascular complication of diabetes. Qishen Yiqi Dripping Pill (QYDP) has been reported to be a renal protective drug. However, the mechanisms remain not certain. This study was performed to investigate the mechanisms of the extract. In this study, Sprague Dawley SD rats were fed with a high-fat diet, and injected with streptozotocin (STZ) to generate a diabetic model. Diabetic rats were administered QYDP.

Project description:Diabetic rats changes gene exprssion in Shenqi Jiangtang Granule-treated rats kidney Diabetic nephropathy (DN) is a major microvascular complication of diabetes. In addition to moderating hyperglycemia, Shenqi Jiangtang Granule (SJG) had a beneficial effect on kidney function in a clinical trial. However, the mechanism involved remains unclear. This study was conducted to identify the underlying molecular mechanisms. A diabetic rat model was generated by using a high-fat diet and streptozotocin (STZ) injection. Then, rats were given SJG at dosages of 800 mg/kg/d by gavage for 8 weeks.

Project description:Hypertension and kidney disease, two related, common, and severe disease entities have been repeatedly associated with genomic variants and metabolic alterations of lysine metabolism. Here, we developed a stable isotope labeling strategy compatible with untargeted metabolomics acquisition to investigate the physiology and molecular spectrum of lysine’s metabolic fate in vivo. Mice received 13C6 labeled lysine through the diet over two months to track more than 100 lysine metabolites across various organs and body fluids. Globally, lysine reacts rapidly with molecules of the central carbon metabolism, as opposed to slow or incorporation into proteins and metabolization into acylcarnitines. Lysine metabolism is accelerated in the rat model of the Dahl salt-sensitive hypertension and kidney damage, chiefly through N-alpha-mediated degradation. Here, lysine administration completely diminished the development of salt-sensitive hypertension and kidney injury. Administration of lysine leads to diuresis, even further acceleration of 13C6 lysine conjugate formation, and inhibition of albumin uptake, thereby protecting from nephron injury and metabolic stress. Lysine conjugates with malonyl-CoA to form a novel metabolite N-malonyl-lysine, to deplete malonyl-CoA from fatty acid synthesis. This process occurs at the expense of protein malonylation. In hypertensive rats with kidney damage, lysine molecules were excreted as fructoselysine, saccharopine and Nε-acetyllysine, via the urine, leading to an overall depletion of central carbon metabolites from the organism and kidney. Consistent with findings in the salt-sensitive rat, lysine challenge of patients with mild kidney damage inhibited tubular albumin uptake, increased lysine conjugate formation in the urine, and reduced TCA cycle metabolites, in contrast to kidney-healthy volunteers. In conclusion, comprehensive lysine isotope tracing mapped an accelerated lysine metabolism in hypertension, and further, lysine administration induced kidney protection in kidney disease.

Project description:Ethnopharmacological relevance: Shexiang Baoxin Pill (SBP) is a traditional formulation of a Chinese patent medicine, which has been commonly used for the treatment of cardiovascular disease (CVD) in China since the 1980s. Previous clinical studies have shown that SBP is safe and effective in patients with CVD, but the mechanism of the therapeutic effect is still poorly understood and requires further research. Aim of the study: This study aims to comprehensively understand the effects and the underlying mechanisms of SBP for CVD treatment by analyzing the whole proteome of myocardial infarction (MI) model rats with or without SBP treatment. Materials and methods: We evaluated the therapeutic effects of SBP on myocardial infarction model (MI) rats by performing the echocardiography analyses after 15-day treatment. And the label-free quantitative proteomic approach was utilized to investigate the whole proteome of the rat heart tissues from MI group (MI rats, n=3), SBP group (MI rats treated with SBP, n=3) and SOG group (sham operated rats, n=3) on the operation day (Day 0) and 15 days after operation (Day 15), respectively. The differentially expressed proteins were subsequently analyzed with bioinformatical methods such as KEGG pathway enrichment analysis, gene ontology (GO)-annotation analysis and protein-protein interaction (PPI) network analysis. Finally, the expression levels of two promising proteins were validated by immunoblotting. Results: The echocardiography analyses show SBP significantly improved the left ventricular fractional shortening (LVFS) and left ventricular ejection fraction (LVEF) of MI rats. Additionally, 134 proteins were differentially expressed both between SBP/MI and SOG/MI, and 15 proteins were found closely related to CVD. The pathway enrichment and GO-annotation analysis of these differentially expressed proteins revealed that the proteins involved in cellular mitochondrial energy metabolism processes, such as fatty acid beta-oxidation and aerobic respiration, were significantly regulated under SBP treatments, of which fatty acid-binding protein 3 (FABP3) and myoglobin (MB) was significantly down-regulated in MI model group compared with SOG group and was returned to the basal level by SBP treatment. Expression levels of these two proteins were confirmed by immunoblotting experiments. Conclusions: These results we obtained in current study probably demonstrated that the cardio-protective effects of Shexiang Baoxin Pill might be achieved through the regulation of energy metabolism homeostasis in cardiac tissue.
