Project description:Induced renal epithelial cells were obtained by direct reprogramming of murine fibroblasts. Their expression profile was compared to control fibroblasts and primary renal tubular epithelial cells.

Project description:In order to study the effect of mesenchymal stem cells on miRNAs in renal tubular epithelial cells during renal fibrosis, and to find new treatment methods for renal fibrosis, we used TGF-β1 to stimulate mouse tubular epithelial cells, co-cultured with mesenchymal stem cells for 48 hours, and collected renal tubular epithelial cells .The renal tubular epithelial cells that were only stimulated by TGF-β1 were used as a control group. High-throughput miRNA sequencing was used to detect the increased and decreased miRNAs after co-culture.

Project description:Mutations in PKD1 cause Autosomal Dominant Polycystic Kidney Disease (ADPKD). To further investigate the impact of Pkd1 knockout on renal tubular cells, a direct reprogramming approach was applied. After direct reprogramming of mouse embryonic fibroblasts to induced renal tubular epithelial cells (iRECs), Pkd1 knockout iREC clones were generated by Cre-mediated recombination of floxed Pkd1 alleles. The knockout clones were compared to their corresponding wild type clones by RNA Sequencing and transcriptome profiling.

Project description:To understand the transcription regulation of renal tubular epithelial cells under stimuli, here we investigated transcriptome, chromatin accessibility and their dynamics through RNA-seq and ATAC-seq under the three types of treatments. We identified genome-wide functional regions which coordinated transcription regulation in human renal proximal tubule epithelial cells (HK2). Our results provide a cell type-specific landscape of chromatin dynamics under stimuli and discovered an important TF in renal tubular epithelial cells that mediated genomic response to different injury stimuli.

Project description:GPX3 is primarily synthesized and secreted by renal tubular epithelial cells and serves as the main source of GPX3 in plasma. A portion of GPX3 adheres to the renal basement membrane, suggesting that GPX3 may also regulate renal cell physiological functions. Our previous work has found that GPX3 expression is downregulated in the renal tubular epithelial cells of mice that have undergone ischemia-reperfusion-induced acute kidney injury, but the specific impact of this downregulation remains unclear. To address this, we constructed mice with specific deletion of GPX3 in renal tubular epithelial cells and subjected them to ischemia-reperfusion modeling. We reported the protective role of native GPX3 in the kidneys under IRI-AKI conditions in mitigating oxidative stress and mitochondrial damage in tubular epithelial cells. The deletion of GPX3 in tubular epithelial cells exacerbated oxidative stress, apoptosis, and mitochondrial dysfunction in IRI-AKI. Renal cortex tissue from control and IRI-modeled mice was used for RNA sequencing. Overall, our data provide an overview of the genetic changes in the kidneys of mice with GPX3 knockout in both non-modeled and IRI-AKI-modeled conditions, laying the groundwork for studying the specific mechanisms by which GPX3 regulates renal function.

Project description:Ischemia-reperfusion injury-induced acute kidney injury is a major cause of chronic kidney disease, lacking effective interventions. We found elevated HNF3α expression in CKD patients, which correlated with collagen deposition, serum creatinine, and urea levels. Conditional knockout of HNF3α in renal tubular epithelial cells protected against IRI-induced renal fibrosis in vivo. To explore the mechanisms by which HNF3α promotes renal fibrosis, we transfected TKPTS cells with Hnf3a overexpression plasmids or control plasmids, and then performed transcriptome sequencing.

Project description:Renal epithelial cells are exposed to mechanical forces due to flow-induced shear stress within the nephrons. We applied RNA sequencing to get a comprehensive overview of fluid-shear regulated genes and pathways in the immortalized renal proximal tubular epithelial cell line. Cells were exposed to laminar fluid shear stress (1.9 dyn/cm2) in a cone-plate device and compared to static controls.

Project description:The cellular and molecular mechanisms by which cisplatin induces nephrotoxicity have been investigated extensively. However, the role of long non-coding RNAs (lncRNAs) in cisplatin-induced nephrotoxicity has not been received much attention. Here, we explore the functions and underlying mechanisms of a novel lncRNA XLOC_032768 in cisplatin-induced nephrotoxicity. Cisplatin treatment resulted in the apoptosis of renal epithelial cells in a mouse model and human renal proximal tubular epithelial cells (HK-2). By performing differentially expressed genes (DEGs) of the transcriptome data, we found the expression of lncRNA XLOC_032768 was significantly repressed by cisplatin treatment, which was also validated by RT-qPCR experiment of in vivo and in vitro model. Overexpression of lncRNA XLOC_032768 significantly inhibited the cisplatin-induced apoptosis of HK-2 and the expression of biomarkers for cisplatin-induced nephrotoxicity. Results from XLOC_032768 overexpression experiment revealed that XLOC_032768 target the tumor necrosis factor (TNF)-α in trans in HK-2 cells and mouse exposed to cisplatin. The administration of lncRNA XLOC_032768 attenuated renal dysfunction, morphological damage, and renal tubular cell injury, which was accompanied by TNF-α preservation, in a mouse model of cisplatin nephrotoxicity. These data indicate that XLOC_032768 suppressed cisplatin-induced apoptosis of tubular epithelial cells and acute kidney injury via a TNF mechanism. LncRNA XLOC_032768 would be a novel agent to reduce cisplatin-induced nephrotoxicity.
