View SamplesGlomerular podocyte cells are critical for the function of the renal ultrafiltration barrier. The highly specialized cell-cell junction of podocytes, the slit diaphragm, has a central role in the filtration barrier. Dendrin is a poorly characterized cytosolic component of the slit diaphragm in where it interacts with nephrin and Cd2ap. In this study, we have generated a dendrin knockout mouse line and explored the molecular interactions of dendrin. Dendrin-deficient mice were viable, fertile and had normal life span.
Wtip- and gadd45a-interacting protein dendrin is not crucial for the development or maintenance of the glomerular filtration barrier.

View SamplesPlatelet-derived growth factor-C (PDGF-C) is one of three known ligands for the tyrosine kinase receptor PDGFR. Analysis of Pdgfc null mice has demonstrated roles for PDGF-C in palate closure and the formation of cerebral ventricles, but redundancy with other PDGFR ligands might hide additional functions. In search of further developmental roles for PDGF-C, we generated mice that were double mutants for Pdgfc -/- and Pdgfra GFP/+. These mice display a range of severe phenotypes including cerebellar malformation, neuronal over-migration in the cerebral cortex, spina bifida and lung emphysema. We focused our analysis on the central nervous system (CNS), where PDGF-C was identified as a critical factor for the formation of meninges and assembly of the glia limitans basement membrane.

View SamplesAdipocyte precursor cells were treated with Pdgfa during 1 or 2 hours in vitro to identify early changes in transciprion in response to treatment. This experiment supports the evidence that Pdgfa induces proliferation and maintenance of adipocyte stem cells. Overall design: Adipocyte precursor cells were isolated by FACS and treated with 30ng/ml of recombinant mouse Pdgfa for 1 or 2 hours.

View SamplesVascular smooth muscle cells (VSMC) are important for contraction, blood flow distribution and regulation of blood vessel diameter, but to what extent they contribute to the integrity of blood vessels and blood-brain barrier function is less well understood. In this report, we explored the impact of the progressive loss of VSMC in the Notch3-/- mouse on blood vessel integrity in the central nervous system

View SamplesPurpose: We found that IFN-g and IL-27 had suppressive effects on ILC2s cultured with IL-33. The goal of this study is to clarify the expressions of RNA induced by IFN-g and IL-27 in ILC2s. Methods: ILC2s were isolated from fat-asociated lymphid clusters (FALC) of wild-type mice. They were cultured with IL-33 (10ng/ml), IL-33 + IFN-g (10ng/ml), or IL-33 + IL-27 (10ng/ml) for 48hrs. RNA was isolated by Allprep DNA/RNA Micro Kit (QIAGEN), and cDNA libraries were prepared by TruSeq RNA Sample Preparation kits v2 (Illumina) according to the manufacturer’s low sample protocol. A HiSeq 1500 system (Illumina) was used for 50 single-end bases (50SE) sequencing. Results: Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to the reference genome (mm9) using Bowtie2 v2.1.0 and TopHat2 v2.0.8. The transcript abundances were estimated as FPKM (fragments per kilobase of exon million fragments mapped) value using Cufflinks v2.1.1. We found that both IL-27 and IFN-g upregulated the expression of STAT1 and IRF1 which are regulated downstream of IFN-g receptor signaling, but there was no difference in the expression of GATA3, a critical transcription factor for ILC2 functions. Conclusions: Our study represents the detailed differences of RNA expressions by RNA-seq technology. Overall design: RNA-Seq analysis of ILC2s cultured with IL-33 (10ng/ml), IL-33 + IFN-g (10ng/ml), or IL-33 + IL-27 (10ng/ml) for 48hrs.
