Acidosis activates the Nrf2-pathway in renal proximal tubule-derived cells through a crosstalk with renal fibroblasts

ABSTRACT: Crosstalk of renal epithelial cells with interstitial fibroblasts plays an important role in kidney pathophysiology. A former study showed that crosstalk between renal epithelial cells and renal fibroblasts protects against acidosis-induced damage. In order to gain further mechanistic insight into this crosstalk we investigated the effect of acidosis on the transcriptome of renal epithelial cells (NRK-52E) and renal fibroblasts (NRK-49F) in co-culture by RNASeq, bioinformatics analysis and experimental validation.

Expression data from EMT-derived NRK-52E cells before and after the AMPKα2 knockdown

Project description:Recent studies have shown that AMPKα2 can regulate epithelial-mesenchymal transition(EMT) processes during kidney fibrosis. However, the underlying mechanisms for AMPKα2 changes in renal tubular EMT remain unclear. TGF-β1 was used to induce epithelial-mesenchymal transition(EMT) in normal rat renal tubular epithelial (NRK-52E) cells. Gene microarray was used to analyze differential gene expression in EMT-derived NRK-52E cells before and after the AMPKα2 knockout

Proteomics of Rat Proximal-Tubule Cell-Culture Models

Project description:Cultured cell lines are widely used for research in the physiology, pathophysiology, toxicology and pharmacology of the renal proximal tubule. The lines that are most appropriate for a given use depend on the genes expressed. New tools for transcriptomic and proteomic profiling using RNA-sequencing (RNA-Seq) and mass spectrometry make it possible to catalog expressed genes in each cell line. This data set is the protoemic data of Rat NRK-52E cell line. We concludeno cell line fully matched the transcriptome of native proximal tubule cells. However, some of the lines tested are suitable for the study of particular metabolic and transport processes seen in the proximal tubule.

Expression data from NRK-52E cells treated with aristolochic acids for 6h, 24h and 72h

Project description:In this study we have examined the effect of sub-cytotoxic exposure to aristolochic acids (1.65µM) at 6h, 24h and 72h on the whole-genome expression profile in a rat proximal renal tubule cell line (NRK-52E). We used microarrays to detail the mechanism of toxicity and possibly carcinogenicity of aristolochic acids in rat renal proximal cells. NRK-52E cells were cultured to confluence on 6-well plates. Cells were then exposed to aristolochic acid dissolved in DMSO (0.1%) at the IC10 concentration at 72h (1.65 ?M) or DMSO only as control. After 6h, 24h and 72h the medium was removed and RNA was extracted from the cells. Three studies were conducted at each time point.

Identification of molecules from dying cells that act as signals to promote proliferation of surrounding cells

Project description:To elucidate the mechanisms underlying epithelial homeostasis, we explored molecules that might serve as M-bM-^@M-^\dangerM-bM-^@M-^] signals in mediating epithelial regeneration with microarray. We hypothesize that soluble factors may have been released from damaged cells to stimulate the proliferation of surviving epithelial cells. In elucidating the mechanism of dying cell-to-surviving cell communication using normal rat kidney NRK-52E epithelial cells, we observed gene expression profiles in these cells after the induction of cell death using hydrogen peroxide. The results demonstrated up-regulation of Interleukin-6, Heme oxygenase-1 and Hypoxia inducible factor-1 alpha in dying cells. Global gene expression changes were measured after induction of cell death in NRK-52E cells after incubation with hydrogen peroxide. Hydrogen peroxide (0, 0.003, 0.006, 0.009% in DMEM) was teated for 1 hour. After wash with PBS, cells were incubated with non-serum DMEM for 12 hours.

RNA-seq of TGF-beta1-induced NRK-52E cells after treatment with 2D- and 3D-EVs

Project description:Renal tubular epithelial cells are the main cells affected in the process of renal fibrosis, and it has been shown that mesenchymal stem cell-derived exosomes can treat renal fibrosis, and then the traditional 2D-EVs production method is inefficient. We efficiently extracted 3D-EVs by coaxial bioprinting, but the mechanism of 3D-EVs for treating renal fibrosis is not yet known. Therefore, we used TGF-beta1 to induce a renal fibrosis phenotype in NRK-52E cells and took 2D- and 3D-EVs for treatment in order to explore the possible differential molecular mechanisms of 2D- and 3D-EVs for renal fibrosis. This approach facilitates the discovery of new mechanisms for exosomes to treat renal fibrosis.
