Project description:The overall goal of this study is to determine the small non-coding RNA expression profile in developing mouse nephron progenitors and whole kidney. Using a limited digestion and negative selection approach, an enriched fraction of nephron progenitors were isolated from E15.5 whole kidney samples followed by small RNA-Sequencing (sRNA-Seq). A total of 3 biological replicates of mouse nephron progenitors and whole kidney samples were used for the sRNA-Seq. The NEBNext Multiplex Small RNA Library Prep Kit allowed us to prepare sequencing libraries from as little as 100ng total RNA. Multiplex sequencing was performed using the Illumina NextSeq 550 system with 50bp single reads, resulting in approximately 18 million reads per sample. Reads were aligned to the mm10 genome using Bowtie2, and the miRDeep2 software package was used to identify and quantify known and novel micro RNA (miRNA) within our sRNA-seq libraries. Differential expression analysis of miRNA expression between nephron progenitor and whole kidney samples identified 162 differentially expressed miRNAs (padj <= 0.05).

Project description:The kidney is a complex organ composed of more than 30 terminally differentiated cell types that all are required to perform its numerous homeostatic functions. De-fects in kidney development are a significant cause of chronic kidney disease in children, which can lead to kidney failure that can only be treated by transplant or dialysis. A better understanding of molecular mechanisms that drive kidney development is important for designing strategies to enhance renal repair and regeneration. In this study, we profiled gene expression in the developing mouse kidney at embryonic day 14.5 at single cell resolution. Consistent with previous studies, clusters with distinct transcriptional signatures clearly identify major compartments and cell types of the developing kidney. Cell cycle activity distinguishes between the “primed” and “self-renewing” sub-populations of nephron progenitors, with increased expression of the cell cycle related genes Birc5, Cdca3, Smc2 and Smc4 in “primed” nephron progenitors. Augmented Birc5 expression was also detected in immature distal tubules and a sub-set of ureteric bud cells, suggesting that Birc5 might be a novel key molecule required for early events of nephron patterning and tubular fusion between the distal nephron and the collecting duct epithelia.

Project description:During mammalian kidney development, mesenchymal nephron progenitors (cap mesenchyme) differentiate into the epithelial cells that go on to form the nephron. Although differentiation of nephron progenitors is triggered by activation of Wnt/b-catenin signaling, constitutive activation of Wnt/b-catenin signaling blocks epithelialization of nephron progenitors. Full epithelialization of nephron progenitors requires transient activation of Wnt/b-catenin signaling. We performed transcriptional profiling of nephron progenitors responding to constitutive or transient activation of Wnt/b-catenin signaling. Nephron progenitors were FACS-isolated from BAC transgenic Six2GFPcre-positive embryonic kidneys at E16.5. Cells were aggregated by centrifugation at 850g for 5min and incubated in 10%FBS/DMEM containing either 4uM BIO or the equal volume of DMSO for 24hrs or 48hrs.

Project description:During kidney development, Notch signaling plays multiple roles including promoting differentiation of nephron progenitors that give rise to all of the epithelial cells found in the nephron. Little is known about what genes Notch signaling regulates and how Notch signaling interacts with other transcription factors. To address this, we carried out genome-wide mapping of Notch2, a major Notch receptor required for differentiation of nephron progenitors, in the embryonic kidney.

Project description:The aim of the study was to investigate whether the trefoil peptide genes, in concerted action with a miRNA regulatory network, were contributing to nutritional maintrenance. Using a Tff3 knock-out mouse model, 21 specific miRNAs were noted to be significantly deregulated when compared to the wild type strain.
