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:Investigate gene expression profiles of Liuwei Dihuang Pill treatment postmenopausal osteoporosis with kidney Yin deficiency in peripheral blood Liuwei Dihuang Pill (LDP), a classic Chinese medicinal formula, has been used to treat PMO with kidney YIN deficiency for three months. Whole human genome oligo microarray were applied to explore the differentially expressed genes before and after LDP treatment.
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: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.
Project description:Gender has strong impact on kidney performance. Female gender tends to be renal protective. PKD/Mhm is rat model for human polycystic kidney disease (PKD) caused by a mutation in gene Anks6. PKD progresses faster in male rats compared with females. We used microarrays to detect gender-dependent gene expression in kidney of 36d old PKD/Mhm rats. Keywords: gender, genotype
