Project description:We analyzed differences in IRI kidneys between WT and Keap1 KD mice (= Nrf2-activated mice). To identify Nrf2-target genes or metabolic genes in kidneys, we examined the mRNA expression profile both in normal (uninjured) and IRI kidneys (at day1 after unilateral IRI) from mice

Project description:Renal recovery following injury relies on cellular regeneration. In the mouse kidney following injury, injured epithelial cells undergoes de-differentiate, proliferate and re-differentiate into functional cells, following a a tightly controlled genetic programme where specific sets of genes are up-regulated. We used microarrays to detail the global programme of gene expression underlying cellular regeneration following injury with or without a HDAC inhibitor, m4PTB, treatment and identified distinct classes of up-regulated genes during this process. Male BALB/c mice underwent 26 minute unilateral ischemia-reperfusion (IR) with contralateral nephrectomy treated with vehicle or 100 mg/kg m4PTB 24 h after inducing renal injury, and kidneys harvested for RNA extraction 12 h later. We sought to obtain kidneys within a similar degree of injury in order to carefully evaluate the effect of m4PTB on expression profiles. To that end, we selected kidneys according to three different criteria of injury: (1) level of serum creatinine at Day1, (2) the level of blood urea nitrogen (BUN) (3) Kim1 expression by qPCR at Day1.5 using haevested kidneys

Project description:Methylation array analyses of 30 CCSKs in comparison with 18 Wilms tumours and normal non-malignant kidneys (2 foetal kidneys and 6 adult kidneys) revealed CCSK tumour DNA to be globally hypermethylated. Four CCSKs, two WTs, two foetal kidneys and 2 adult kidneys were analysed as technical duplicates on different arrays.

Project description:Acute kidney injury (AKI) manifests as a major health concern particularly for the elderly and understanding related proteome changes is critical for prevention and development of novel therapeutics to recover kidney function, and to mitigate the susceptibility for recurrent AKI, or development of chronic kidney disease. In this study, mouse kidneys were subjected to ischemia-reperfusion injury while the contralateral kidneys remained uninjured to assess changes in the kidney proteome. A fast-scanning ZenoTOF 7600 mass spectrometer was used for comprehensive data-independent acquisition (DIA) for protein identification and quantification. Short microflow gradients, and the generation of a deep kidney-specific spectral library allowed for comprehensive and high-throughput assays. Upon AKI the kidney proteome was completely remodeled, and over half of the 3,945 quantified protein groups changed significantly. Downregulated proteins in the injured kidney were involved in energy production, including numerous peroxisomal matrix proteins, many related to lipid metabolism, such as ACOX1, CAT, EHHADH, ACOT4, ACOT8, and Scp2. Injured mice exhibited severely declined health. The comprehensive and sensitive kidney-specific DIA assays, highlighted in this work, feature high-throughput analytical capabilities to achieve deep coverage of the kidney proteome, and will serve as useful tool for the development of novel therapeutics aimed at remediating kidney function.

Project description:Introduction: Renal ischemia-reperfusion (IR) causes acute kidney injury (AKI) with high mortality and morbidity. The objective of this study was to ameliorate kidney IR injury and identify novel biomarkers for kidney injury and repair. Methods: Left renal ischemia was induced in rats by clamping renal artery for 45 minutes, followed by reperfusion and right nephrectomy. Thirty minutes prior to ischemia, rats (n=8/group) received Valproic Acid (150 mg/kg; VPA), Dexamethasone (3 mg/kg; Dex) or Vehicle (Saline) intraperitoneally. Animals were sacrificed at 3h, 24h or 120h post- IR and blood, urine and kidney were collected. Results: Serum creatinine (mg/dL) at 24 h IR in VPA (2.7±1.8) and Dex (2.3±1.2) was reduced (P<0.05) compared to Vehicle (3.8±0.5). At 3h post-IR, urine albumin (mg/ml) was higher in Vehicle (1.47±0.10), VPA (0.84±0.62) and Dex (1.04±0.73) compared to uninjured/untreated control (0.14±0.26) group. At 24h post-IR urine Lipocalin-2 (µg/ml) was significantly higher (P<0.05) in VPA, Dex and Vehicle groups (9.61-11.36) compared to uninjured/untreated control (0.67±o.29); also, Kidney Injury Molecule-1 (KIM-1; ng/ml) was significantly higher in VPA, Dex and Vehicle groups (13.7-18.7) compared uninjured/untreated control (1.7±1.9). KIM-1 levels were significantly (P<0.05) higher in all groups compared to uninjured/untreated control levels. Histopathology at 3h post IR demonstrated (P<0.05) reduction in ischemic injury in the renal cortex in VPA (Grade 1.6± 1.5) compared to Vehicle (Grade 2.9±1.1) group. Inflammatory cytokines IL1β and IL6 were down-regulated in VPA and Dex groups. BCL2 was higher in VPA group. DNA microarray analysis demonstrated reduced stress response and injury, and improved recovery related gene expression in the kidneys of VPA treated animals. Conclusions: VPA administration reduced kidney IR injury and improved regeneration. KIM-1 and Lipocalin-2 appear to be promising early urine biomarkers of acute ischemic kidney injury.

Project description:While it is clear that iron deficiency affects both human and rodent development, and particularly kidney development, the precise pathological changes that occur with iron deficiency have not been distinguished. For example, it is not clear which compartment of the kidney is predominantly affected nor it is clear either which stage of development or which cell type require the most iron. In this study, we used an in vivo mouse model of iron deficiency in order to better understand the targeting of iron in the developing kidney. Mouse kidneys at the embrionic stage E15 were used for the total RNA extraction

Project description:Single cell RNAseq analysis of kidneys from Hepta-ANG1-treated and vehicle-treated mice identified endothelial-specific gene signatures and emergence of a new glomerular endothelial subpopulation associated with improved kidney function. Total RNA of whole kidneys was sequenced to compare the transcriptional response of control and VE-PTPiKO kidneys after 5 hours of reperfusion. We saw fewer genes altered in the VE-PTPiKO kidney after IR injury compared to control.

Project description:We used microarray to investigate the influence of zymolyase treatment which is used for degradation of yeast cell wall. Two types of RNA extraction methods were used, and zymolyase preprocessing was applied to one among them. The qualities of total RNA extracted by two extraction methods were checked, and then RNAs were used for generating cloned DNA and RNA. Finally, two types of cRNA were hybridized to Affymetrix yeast genome 2.0_array. Keywords: comparison of RNA extraction process
