Gene expression profiling of E18.5 FoxD1 Cre;Dicer and control embryonic kidneys

ABSTRACT: The aim of this study is to address the functional role of miRNAs in the FoxD1+ renal stroma progenitors and derivatives during embryonic kidney development. To achieve this, we generated transgenic mice that lack miRNAs in the renal stroma lineage (FoxD1 Cre;Dicer), and performed a microarray analysis on E18.5 whole kidneys to determine the transcriptional changes. 3 litters of E18.5 FoxD1 Cre;Dicer and control littermate kidneys were used for the microarray analysis. Each litter consists of kidneys pooled from 2 embryos per genotype for the RNA extraction.

Renal stromal miRNAs are required for normal nephrogenesis and glomerular mesangial survival.

Physiological reports 20151001 10

MicroRNAs are small noncoding RNAs that post-transcriptionally regulate mRNA levels. While previous studies have demonstrated that miRNAs are indispensable in the nephron progenitor and ureteric bud lineage, little is understood about stromal miRNAs during kidney development. The renal stroma (marked by expression of FoxD1) gives rise to the renal interstitium, a subset of peritubular capillaries, and multiple supportive vascular cell types including pericytes and the glomerular mesangium.

Gene expression comparison of E14.5 Foxd1 null and wild type kidneys

Project description:Forkhead transcription factors are essential for diverse processes in early embryonic development and organogenesis. Foxd1 is required during kidney development and its inactivation results in failure of nephron progenitor cell differentiation. Foxd1 is expressed in interstitial cells adjacent to nephron progenitor cells, suggesting an essential role for the progenitor cell niche in nephrogenesis. To better understand how cortical interstitial cells in general, and FOXD1 in particular, influence the progenitor cell niche, we examined the differentiation states of two progenitor cell subtypes in Foxd1-/- tissue. We found that while nephron progenitor cells are retained in a primitive CITED1-expressing compartment, cortical interstitial cells prematurely differentiate. To identify pathways regulated by FOXD1, we used microarray analysis and screened for target genes by comparison of Foxd1 null and wild type tissues. We chose the E14.5 timepoint because at this stage nephron differentiation is present in wild type kidneys but absent from Foxd1 null kidneys. We examined genes that were upregulated or downregulated in the Foxd1 null compared to wild type. Embryonic kidneys were harvested from Foxd1-/- and wild type littermates from three E14.5 litters. Three biological replicates were generated per genotype, each containing two non-littermate kidney pairs. Sex of embryos was not determined.

miR-132 mediates renal fibrosis: miRNA profiling of foxd1-derivative interstital cells derived from murine fibrotic kidneys compared to healthy kidneys

Project description:Chronic kidney disease is associated with progressive renal fibrosis, where perivascular cells give rise to the majority of Î±-SMA positive myofibroblasts. We sought to identify pericytic miRNAs that could serve as a target to decrease myofibroblast formation. We induced kidney fibrosis in FoxD1-GC;Z/Red-mice by unilateral ureteral obstruction (UUO) followed by FACS sorting of dsRed-positive FoxD1-derivative cells and miRNA profiling. MiR-132 selectively increased 21-fold during pericyte-to-myofibroblast formation whereas miR-132 was only 2.5-fold up in total kidney lysates (both in UUO and ischemia-reperfusion injury). MiR-132 silencing in UUO decreased collagen deposition (35%) and tubular apoptosis. Immunohistochemistry, western blot and qRT-PCR confirmed a similar decrease in interstitial Î±-SMA+ cells. Pathway analysis identified a rate-limiting role for miR-132 in myofibroblast proliferation that was confirmed in vitro. Indeed, antagomir-132 treated mice displayed a reduction in the number of proliferating, ki67+ interstitial myofibroblasts. Interestingly, this was selective for the interstitial compartment and did not impair the reparative proliferation of tubular epithelial cells, as evidenced by an increase in ki67+ epithelial cells, as well as increased (p-)RB1, Cyclin-A and decreased RASA1, p21 levels in kidney lysates. Taken together, silencing miR-132 counteracts the progression of renal fibrosis by selectively decreasing myofibroblast proliferation and could potentially serve as a novel antifibrotic therapy.

Targets for renal carcinoma growth control identified by screening FOXD1 cell proliferation pathways

Project description:FOXD1 regulates proliferation of clear cell renal cell carcinoma (ccRCC) cells, and ccRCC cells in which FOXD1 has been inactivated do not form tumors efficiently in an animal model. Reproducing growth inhibition in tumor cells by inhibiting FOXD1 pathways presents an possible therapeutic approach for ccRCC and other cancers. We have established an analysis strategy to identify FOXD1-regulated target pathways that may be therapeutically tractable and compounds that modulate these pathways were selected for testing.

Genomic landscape of the developing kidney upon conditional and time-dependent knockout of Wt1

Project description:We are characterizing global expression in the whole kidney at developmental stage E18.5, where we have used three Cre strains that result in knock out Wt1 in different cell types during renal development. Here the purpose is to identify the developmental stage at which the loss of Wt1 impacts kidney development, specifically in the context of a degree of disruption capable of ending in pediatric kidney cancers. Total RNA was isolated from whole kidneys of E18.5 mouse embryos following a variety of conditional knockouts of Wt1, plus appropriate control animals.
