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: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:We investigated the cGAS-STING inflammatory pathway differential activity among both sexes in T2DN rats and its impact on the temporal progression of the diabetic kidney disease. Here we used both male and female old and young T2DN rats. The cGAS-STING pathway presented distinct protein expression profiles between male and female T2DN rats, which significantly intensify with aging. In male T2DN rats, pro-inflammatory genes are particularly heightened in comparison to female rats of similar age, and such levels are further exacerbated with age. Interestingly, a comprehensive RNA-Seq analysis conducted in the kidney cortex of both sexes of T2DN rats, in younger and older ages, disclosed several central molecules, with crucial genes identified within the cGAS-STING pathway. Our study showed the intricate sexual differences in the development and progression of DKD and proposed the fundamental role of cGAS-STING pathway in disease development.
Project description:Diabetes is associated with altered metabolism, but how altered metabolism contributes to the development of complications such as diabetic kidney disease is unknown. We used a systems approach with transcriptomics and mass spectrometry (MS)-based metabolomics to determine alterations in carbohydrate and lipid metabolism in kidney cortex tissue from 24-week-old BKS db/db diabetic mice and db/+ controls. Glomerular-deprived kidney cortex (kidney proximal tubule) gene expression was profiled and compared with metabolite data. Transcriptomic and metabolomic profiling demonstrated an increase in both glycolysis and fatty acid beta-oxidation,
Project description:Gene expression in kidney cortex of diabetic mice and menopausal diabetic mice following 6 weeks of diabetes. Diabetes was induced with low-dose streptozotocin injections and menopause was induced by injection of 4-vinylcyclohexene diepoxide. Samples = 12
Project description:The experiment was designed to study the effects of blood pressure on gene expressions in the kidney cortex. Kidney cortex was harvested from seven SHR rats and eight WKY rats at 60 weeks of age. Both right and left kidney were taken out and pooled during RNA extraction
