Ischemic vs. nephrotoxic acute renal failure, early time points (2h and 8h)

ABSTRACT: Acute renal failure (ARF) has high morbidity and mortality. In animal ARF models, effective treatments must be administered before or shortly after the insult, limiting their clinical potential. We used microarrays to identify early biomarkers that distinguish ischemic from nephrotoxic ARF, or that detect both injury types. We compared rat kidney transcriptomes 2 and 8 hours after ischemia/reperfusion and after mercuric chloride. Quality control and statistical analyses were necessary to normalize inter-experimental groups, eliminate outliers, and exclude unaltered genes. Principal component analysis revealed distinct ischemic and nephrotoxic trajectories, and clear array groupings. Therefore, we used supervised analysis, t-tests and fold changes, to compile gene lists for each group, exclusive or non-exclusive, alone or in combination.

Principal component analysis revealed distinct ischemic and nephrotoxic trajectories, and clear array groupings. Therefore, we used supervised analysis, t-tests and fold changes, to compile gene lists for each group, exclusive or non-exclusive, alone or in combination. We used two lots of microarrays (Lot 1, n = 24, Lot 2, n = 12), for a total of 36 microarrays. Five of them were duplicates, where two aliquots of RNA from the same rat were processed independently and hybridized to separate microarrays. Normal rats were used in both lots (n = 3 for each lot) for normalization.

PGE2 promotes recovery from established Nephrotoxic Serum Nephritis in mice.

Project description:We induced acute nephritis by single injection of sheep nephrotoxic serum in mice and then treated the mice with prostaglandin E2. We used microarrays to examine the global gene expressions during recovery from nephrotoxic nephritis by prostaglandin E2. Acute nephristis was induced in female mice by single injection of sheep Nephortoxc Serum (NTS), followed by prostaglandin E2 administration daily starting from day 2 after NTS administration. Mice were sacrificed on day 7 and RNAs were isolated from kidney. The RNA samples were subjected to mouse gene 1.0 ST array analysis.

Gene expression in B cells from mice with the autoimmune disease nephrotoxic nephritis

Project description:Studying the differences in glycosylation in B cells of normal mice and mice with an autoimmune disease (nephrotoxic nephritis). Differences in glycosylation in B cells of normal mice and mice with an autoimmune disease (nephrotoxic nephritis) were studied via gene expression analysis. RNA from mouse resting spleen B cells and B cells stimulated with antiCD40, CpG, and IL4 for 5 days, was isolated and prepared. One sample for each class was prepared. RNA was labeled and hybridized to the GLYCOv3 array. Resulting Gene expression patterns were analyzed.

Single cell transcriptomic analysis of female mice after rhabdomyolysis-induced nephrotoxic injury

Project description:We found that PTC undergo polyploidization immediately after glycerol-induced rhabdomyolysis (nephrotoxic-AKI). Polyploidization of PTC is controlled by YAP1. Block of YAP1 related polyploidization of TC employing a specific inhibitor of YAP1 transcriptional activity (CA3) after the acute phase of damage prevented CKD progression after AKI. To identify novel pathways and potential targets involved in AKI response and subsequent CKD development, we generated single-cell RNA sequencing (scRNAseq) datasets from nephrotoxic-AKI female mice treated with vehicle or CA3 starting from 4 days after AKI. Mice were sacrificed two weeks after AKI, when blood urea nitrogen levels, that reflect kidney functionality, were found to start diverging between treated and control mice, but before CKD development.

The effect of circulating Klotho in response to nephrotoxic serum (NTS)-induced injury

The direct effect of mycophenolate mofetil on podocytes in nephrotoxic serum nephritis

Project description:The goal of our study was to characterize glomerulus and particularly podocyte biology during MMF treatment in an immune-triggered proteinuric glomerulopathy. Therefore, nephrotoxic serum nephritis was induced in three-week old wild-type mice. On day 3, half of the mice were treated with MMF (100 mg/kgBW/d p.o.) (NTS+MMF) for one week, the other half of animals with vehicle (NTS+veh). A further group without induction and treatment served as controls (C). On day 10, we performed proteomic analysis of glomeruli.
