Mouse kidney tissue: UUO-METTL3fl/fl, cre T vs. UUO-METTL3fl/fl, wt

ABSTRACT: 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.

Kidney proteomics in the unilateral ureter obstruction (UUO) mouse model

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.

Transcriptional profiles of kidneys that underwent reversible UUO model using model mice for erythropoietin-deficiency anemia (ISAM)

Project description:We have established a novel mouse model for postnatal erythropoietin (Epo)-deficiency anaemia, designated ISAM (inherited super anemic mouse) using a transgenic complementation rescue technique. To identify responsible signals for myofibroblastic transformation of Renal Erythropoietin-producing cells (REPs), we examined the mRNA expression profile of whole ISAM kidneys that underwent reversible UUO model. Unilateral ureteral obstruction (UUO)-induced gene expression changes were analyzed. Three UUO-treated samples (Clip), three reversed UUO kidneys (ClipR-14), and two sham-treated and one untreated samples were compared.

Axl targeting in experimental unilateral ureteral obstruction

Project description:We investigated if Axl receptor tyrosine kinase was up-regulated in unilateral ureteral obstruction (UUO) and if blocking of Axl by a small molecule called BGB324 (also called Bemcentinib) reduces fibrosis development in the ligated kidney as compared to treatment with its vehicle alone.

Multi Omics analysis of fibrotic kidneys in two mouse models (Unilateral ureter obstruction (UUO) model MS data set)

Project description:Kidney fibrosis represents an urgent unmet clinical need due to the lack of effective therapies and inadequate understanding of the molecular pathogenesis. We have generated a comprehensive and integrated multi-omics data set (proteomics, mRNA and small RNA transcriptomics) of fibrotic kidneys that is searchable through a user-friendly web application. Two commonly used mouse models were utilized: a reversible chemical-induced injury model (folic acid (FA) induced nephropathy) and an irreversible surgically-induced fibrosis model (unilateral ureteral obstruction (UUO)). mRNA and small RNA sequencing as well as 10-plex tandem mass tag (TMT) proteomics were performed with kidney samples from different time points over the course of fibrosis development. The bioinformatics workflow used to process, technically validate, and integrate the single data sets will be described. In summary, we present temporal and integrated multi-omics data from fibrotic mouse kidneys that are accessible through an interrogation tool to provide a searchable transcriptome and proteome for kidney fibrosis researchers.

Spiny mice (Acomys cahirinus) activate unique transcriptional programs after severe kidney injuries and regenerate organ function without fibrosis

Project description:Purpose: The goal of this study was to characterize the kidney transcriptome of Mus musculus and Acomys cahirinus after unilateral ureteral obstruction (UUO) kidney injury. Methods: Kidney mRNA-seq profiles of 10 week old mouse and spiny mouse were generated at 2 day and 5 days after unilateral ureteral obstruction injury in triplicate, using Illumina NovaSeq 6000. The sequence reads that passed quality filters were analyzed at the transcript isoform level with Salmon, edgeR and a limma-voom pipeline in R. Results: For both Mus musculus and Acomys cahirinus kidneys, we mapped about 50 million sequence reads per sample to the mouse transcriptome and identified 20580 transcripts in kidneys of Mus musculus and 54075 transcripts in the kidneys of Acomys cahirinus. Using 1.5 fold change and FDR < 0.05, number of transcripts that are significantly different between Mus musculus samples: 3915 between normal and day 2 after UUO, 5365 between normal and day 5 after UUO. For Acomys cahirinus: 1765 between normal and day 2 after UUO, 2499 between normal and day 5 after UUO. Conclusions: Our study demonstrate there were many conserved responses to kidney injury between M. musculus and A. cahirinus despite the divergent outcomes for kidney fibrosis.

TIMP2 and TIMP3 have divergent roles in early renal tubulointerstitial injury

Project description:Tissue inhibitors of metalloproteinases (TIMP) are endogenous inhibitors of matrix metalloproteinases (MMP). While TIMP2 and TIMP3 inhibit MMPs, TIMP3 also inhibits activation of pro-MMP2 whereas TIMP2 promotes it. Here we assessed the differential role of TIMP2 and TIMP3 in renal injury using the unilateral ureteral obstruction model. Gene microarray assay showed that post-obstruction, the lack of TIMP3 had a greater impact on gene expression of intermediate, late injury- and repair-induced transcripts, kidney selective transcripts and solute carriers. Renal injury in TIMP3-/-, but not in TIMP2-/- mice increased expression of collagen type I/III, connective tissue growth factor, transforming growth factor-Î² and the downstream Smad2/3 pathway. Interestingly, ureteral obstruction markedly increased MMP2 activation in the kidneys of TIMP3-/- mice which was completely blocked in the kidneys of TIMP2-/- mice. These changes are consistent with enhanced renal tubulointerstitial fibrosis in TIMP3-/- and its reduction in TIMP2-/- mice. The activity of tumor necrosis factor-Î± converting enzyme, caspase-3 and mitogen activated kinases were elevated in the kidneys of TIMP3-/- but not TIMP2-/- mice, suggesting enhanced activation of apoptotic and pathological signaling pathways only in the obstructed kidney of TIMP3-/- mice. Thus, TIMP2 and TIMP3 play differential and contrasting roles in renal injury, TIMP3 protects from damage whereas TIMP2 promotes injury through MMP2 activation.
