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.

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.

Genome-wide analysis of gene expression in normal and fibrotic mouse kidneys and normal and fibrotic mouse lungs

Project description:In this study, adult virgin female BALB/C mice were kidney and lungs were harvested for RNA extraction (healthy kidney and lung). Adult virgin female BALB/C mice were subjected to unilateral ureter obstruction (UUO) to induce kidney fibrosis and the fibrotic kidney was harvested for RNA extraction. Adult virgin female BALB/C mice were subjected to intratracheal administration of bleomycine to induce lung fibrosis and the fibrotic lungs was harvested for RNA extraction.

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.

RNA sequencing of sham-operated and unilateral ureteral obstruction (UUO)-operated mouse kidneys in Pax8Cre+ and Kdm6afl/Y Pax8Cre+ knockout mice

Project description:RNA-sequencing of mouse left kidneys for which the left ureter was obstructed (UUO) or not obstructed (sham) animals, isolated 7 days after the surgery in normal mice and mice in which the Kdm6a gene was deleted from tubule epithelial cells

Microarray analysis revealed novel genes and pathways associated with neonatal unilateral ureteral obstruction

Project description:Congenital obstructive nephropathy (CON) is the leading cause of pediatric chronic kidney diseases with high morbidity and mortality.To identify differentially expressed genes, microarray analysis was performed using the unilateral ureteral obstruction (UUO)-induced neonatal rat model of CON.

Profiling of miRNA expression in mouse SHAM kidneys

Project description:Profiling of miRNA expression in mouse SHAM kidneys 9–12 weeks old male C57BL/6 mice were purchased from Charles River. Mice underwent anesthesia by intraperitoneal injection of pentobarbital (50 mg/kg body weight) and were subjected to Unilateral Ureteral Obstruction (UUO). After standard laparotomy, the left proximal ureter was exposed and ligated with 4-0 silk at two points. The sham operation consisted of a similar identification of the left ureter without ligation. Treated (S numbers) and non-treated (C numbers) mice miRNA expressions were then compared.

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.

Proteomic profiling in mouse kidneys post-UUO

Project description:Increased export of transglutaminase-2 (TG2) by tubular epithelial cells (TECs) into the surrounding interstitium modifies the extracellular homeostatic balance leading to fibrotic membrane expansion. Although silencing of extracellular TG2 ameliorates progressive kidney scarring in animal models of chronic kidney disease, the pathway through which TG2 is secreted from TECs and contributes to disease progression has not been elucidated. In this study, we developed a global proteomic approach to identify binding partners of TG2 responsible for TG2 externalization in kidneys subjected to unilateral ureteric obstruction, using TG2-knockout kidneys as negative controls. We report a robust and unbiased analysis of the membrane interactome of TG2 in fibrotic kidneys relative to the entire proteome post-UUO detected by SWATH-mass spectrometry.
