Project description:Cadmium accumulation in kidney results in an irreversible chronic toxicity, but the underlying mechanisms are not clear. Transcriptomics assay may provide insight for the involved complex molecular networks. We used Affymetrix RTA arrays to detail the global gene expression profile of kidney tissues of SD rats with chronic exposure to Cadmium, and identified distinct classes of cadmium exposure related mRNA and pathways.
Project description:To investigate the gene expression profile of genamycin induced nephrotoxicity in a time-series aspect, SD rats were administrated once daily with saline, genamycin 80 mgkg for 28 consecutive days by intramuscular injection folled by 28 days recovery. Kidney samples were collected for microarray analysis and histological examination. There were 4360 and 4323 regulated genes for females and males, respectively, however, the overlapping expression genes coregluated at each time point were few, with 2 for females and 12 for males. By Principle Component Analysis and Hierarchical Cluster, the gene expression patterns were apparently associated with the disease stage of the nephrotoxicity,while GO Annotation showed the biological processes were specific to each course of this nephrotoxicity.Our studymapped the different gene expression patterns at the initiation, development and recovery stage of gentamycin-induced nephrotoxicity Gene expression in kidney from SD rats administrated once daily with saline or 80 mg/kg genamycin by intramuscular injection for 28 consecutive days follwed by 28 days recovery were measured using Aglient Rat Whole Genome 4*44 k array
Project description:Fecal samples collected on day 5 from randomly selected colitic SD rats were analyzed for gut microbiota by sequencing the V4 region of the 16S rRNA gene. The orally administered Dex-P-laden NPA2 coacervate (Dex-P/NPA2) significantly restores the diversity of gut microbiota compared with colitic SD rats in the Dex-P/PBS group and the untreated colitic rats (Control).

Project description:Transcriptional profiling of plasma exosomes came from SD rats that underwent subarachnoid hemorrhage (SAH) and sham operation (Sham) rats. The goal was to identify the changes of RNA in plasma exosomes after subarachnoid hemorrhage in SD rats.
Project description:SD rats were intramuscular injected with dexamethasone to induce osteCPorosis, and treated with APS. Then, colonic epithelia of control, osteCPorotic and APS-treated osteCPorotic rats were collected for MethylC-capture sequencing .

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.
