Project description:The mRNA transcriptome and m6A methylation microarray profiling of mouse kidney tissues. Kidney tissues from the sham-operated group and unilateral ureteral ligation/obstruction (UUO) kidney tissues were compared. The latter were mainly fibrotic kidney tissues. The goal was to identify the effect of the renal fibrosis on gene expression and corresponding m6A modifications during kidney fibrosis.

Project description:Discoidin domain receptor 1 (DDR1) is a collagen receptor with tyrosine kinase activity, and its expression is enhanced in various disease conditions. Although previous research suggests that DDR1 contributes to renal disease progression, DDR1 inhibitors for renal fibrosis have yet to be developed. In this study, we used unilateral ureteral obstruction (UUO) mice to investigate whether CH6824025, a strong and selective DDR1 phosphorylation inhibitor, can improve renal fibrosis. Furthermore, to analyze its action in detail, we performed 10x Visium spatial transcriptomics (ST) analysis on the kidney. Orally administered CH6824025 suppressed the phosphorylation of DDR1 in renal tissue, and the amount of hydroxyproline, the Sirius red-positive area, and the mRNA expression of fibrosis and inflammation-related genes in the kidney were significantly decreased. 10x Visium ST analysis suggested that DDR1 is mainly expressed in distal nephrons under normal conditions, but that its expression appears to increase in the injured proximal tubules in UUO mice. Comparing mRNA expression in DDR1 positive spots in the vehicle and the CH6824025 administration group, oxidative phosphorylation and mitochondrial dysfunction were improved, and pathways involved in fibrosis inhibited in the CH6824025 administration group. Downstream analysis suggested that mRNA expression changes in the CH6824025 administration group contribute to the inhibition of cell movement. Taken together, our findings suggest that CH6824025 inhibited the migration of inflammatory cells to the injury site in UUO mice, reduced inflammation, and brought about the maintenance of cell homeostasis and inhibition of fibrosis. DDR1 inhibitors are expected to be a promising treatment for renal fibrosis.

Project description:Label-free quantitative proteomics for mouse kidney tissue of UUO vs Sham was used for discovery of differential expressed proteins in the process of renal fibrosis. Compared to sham mice, we found that 216 upregulated proteins and 215 downregulated proteins in UUO mice according to fold change ≥ 5, adjusted-p ≤ 0.01. Then, we will study the potential mechanism according to differential expressed proteins.

Project description:Treatments for kidney fibrosis represent an urgent yet unmet clinical need. Effective therapies are limited due to not well understood molecular pathogenesis. We aimed at generating a comprehensive and integrated multi-omics data set (RNA/ microRNA transcriptomics and proteomics) of fibrotic kidneys which will be searchable through a user-friendly web application. Therefore, two commonly used mouse models were utilized: a reversible chemical-induced injury model (folic acid (FA) induced nephropathy) and an irreversible surgical-induced fibrosis model (unilateral ureteral obstruction (UUO)). RNA and small RNA sequencing as well as MS/MS with 10-plex tandem mass tags proteomics were performed with kidney samples from different time points over the course of fibrosis development. In summary, we present temporal and integrated multi-omics data from fibrotic mouse kidneys which are accessible through an interrogation tool to provide a searchable transcriptome and proteome for kidney fibrosis researcher.

Project description:Renal fibrosis as the final outcome of many renal diseases, has always been paid more attention to by the researchers. To better understand whether lncRNAs could be a player in this process or be a biomarker for renal fibrosis diagnosis, we compared transcriptome sequencing data on renal tissues and urine respectively between UUO and shamed (Sham) rat model. Numerous genes including lncRNAs with significant changes in their expression were identified. 24 lncRNAs were up-regulated and 79 lncRNAs were down-regulated in the renal tissues of the UUO rats. 625 lncRNAs were up-regulated and 177 lncRNAs were down-regulated in urines of the UUO rats. Among the lncRNAs upregulated in renal tissue of UUO rats, 19 lncRNAs were predicted containing several conserved Smad3 binding motifs in the promoter. Among them, lncRNAs with putative promoter containing more than 4 conserved Smad3 binding motifs were demonstrated to be induced by TGF-β significantly in NRK-52E cells. We further confirmed that lncRNA TCONS_00088786 and TCONS_01496394 were regulated by TGF-β stimulation and also can influence the expression of some fibrosis-related genes through a feedback loop. Based on transcriptome sequencing data, bioinformatics analysis and qRT-PCR detection, we also demonstrated lncRNA in Urine are detectable and might be a novel biomarker of renal fibrosis. These data provide new information about the involvement of lncRNAs in renal fibrosis, indicating that they may serve as candidate biomarkers or therapeutic targets in the future.

Project description:Numerous studies have proven the critical role of macrophages in the renal fibrosis process. Notably, G Protein-coupled Estrogen Receptor 1 (GPER1), a novel estrogen receptor, has been shown to play a ubiquitous role in the regulation of macrophage activities and proinflammatory pathways. However, the precise role of GPER1 in macrophage-mediated renal fibrosis is unknown. In this study, we aimed to investigate the function of macrophage GPER1 in the UUO-induced renal fibrosis model. Compared to vehicle-treated ovariectomized (OVX) female and male UUO models, we observed that G-1 (GPER1 agonist)-treated OVX female and male UUO mice had fewer renal fibrotic lesions and less M1 and M2 macrophage infiltration in the kidney tissues. Conversely, Gper1 deletion in male UUO mice accelerated renal fibrosis and increased inflammation. In vitro studies also revealed that GPER1 activation reduced M0 macrophage polarization towards M1 and M2 phenotypes. The RNA sequencing analysis and immunoblotting indicated that GPER1 activation was primarily involved in downregulating immune pathways activation and inactivating MAPK pathways. Tubular epithelial cells co-cultured with G1-pretreated M1 macrophages exhibited fewer injuries and immune activation. In addition, fibroblasts co-cultured with G1-pretreated M2 macrophages showed downregulated extracellular matrix expression. Overall, this is the first study to demonstrate the effect of GPER1 on macrophage-mediated renal fibrosis via inhibition of M1 and M2 macrophage polarization. These findings indicate that GPER1 may be a promising therapeutic target for the treatment of renal fibrosis.
