Project description:EGFP (control) and TEADi expressing podocytes were generated by lentivirus transduction to analyze transcriptional signaling by YAP/TAZ-TEAD. Tetracycline-inducible TEADi is a GFP-tagged inhibitor of the interaction of YAP1 and TAZ with TEAD transcription factors. pInducer20 EGFP-TEADi was a gift from Ramiro Iglesias-Bartolome (Addgene plasmid # 140145 ; http://n2t.net/addgene:140145 ; RRID:Addgene_140145). TEADi was previously described: YAP1/TAZ-TEAD transcriptional networks maintain skin homeostasis by regulating cell proliferation and limiting KLF4 activity. Yuan Y., Park J., Feng A., Awasthi P., Wang Z., Chen Q., Iglesias-Bartolome R.. Nat Commun 11, 1472 (2020). 10.1038/s41467-020-15301-0. Transcriptome profiling (RNA-Sequencing) and differential gene expression analysis of 3 independent replicates per genotype was performed. TEADi podocytes exhibit transcriptional changes compared to WT cells including downregulation of prominent YAP target genes like CTGF, CYR61 and ANKRD1.
Project description:Purpose: Next-generation sequencing (NGS) was used to define the transcriptome of native mouse podocytes and non-podocytes glomerular cells as part of a project aiming to define the molecular fingerprint of mouse podocytes. Method: Glomeruli from 29 Gt(ROSA)26Sortm4(ACTB-tdTomato,-EGFP)Luo/J x hNPHS2Cre mice at the age of 10 weeks were purified and a single cell solution was prepared to seperate GFP-expressing (podocytes) and GFP-negative (non-podocytes glomerular cells) cells by FACS sorting. RNA was extracted and prepared for further analysis using directional, polyA+ library preparation. An Illumina HiSeq2500 was used for a paired-end sequencing of 100 cycles . Salmon and Sleuth were used for downstream analysis. Results: A total of 100 Million reads each from podocytes and non-podocytes glomerular cells could be used for further analysis.
Project description:We generated NUP133 mutant podocytes to model human hereditary SRNS in vitro. A subtype of SRNS is caused by monogenetic mutations of the nuclear pore complex including NUP133. Human immortalized podocytes were genome edited applying the CRISPR/Cas9 technique to create NUP133 KO cells (“KO-1”). cDNA of NUP133-WT or causative variants NUP133 c.2922T>G (“Mutation-1”) or NUP133 c.3335-11T>A (“Mutation-2”) were stable expressed into this KO background by lentiviral transduction. Transcriptome profiling (RNA-Sequencing) and differential gene expression analysis was performed in triplicate for each cell line. NUP133 mutant podocytes showed no overt transcriptional changes compared to NUP133-WT cells.
Project description:We generated NUP133 WT and KO podocytes to model human hereditary SRNS in vitro. A subtype of SRNS is caused by monogenetic mutations of the nuclear pore complex including NUP133. Immortalized human podocytes were genome edited applying the CRISPR/Cas9 technique and two independent NUP133 sgRNAs. Two monoclonal cell backgrounds were used to create two matching sets of NUP133 WT and KO cells (WT-1 versus KO-1 and WT-2 versus KO-2). Transcriptome profiling (RNA-Sequencing) and differential gene expression analysis was performed in duplicate for each cell line. NUP133 KO podocytes exhibit vast transcriptional changes compared to WT cells.
Project description:We generated EPB41L5 WT and KO podocytes to model human glomerular kidney disease in vitro. Immortalized human podocytes were genome edited applying the CRISPR/Cas9 technique. Two monoclonal cell lines were generated for WT and KO genotypes (WT-1, WT-2, KO-1 & KO-2). Transcriptome profiling (RNA-Sequencing) and differential gene expression analysis was performed in duplicate for each cell line. EPB41L5 KO podocytes exhibit transcriptional changes compared to WT cells. Analyzed cell were previously described: Schell C, Rogg M, Suhm M, et al. The FERM protein EPB41L5 regulates actomyosin contractility and focal adhesion formation to maintain the kidney filtration barrier.

Project description:Gene expression profiles of ZHBTc4 ES cells expressing EGFP, Oct4-EGFP, Nr5a2-EGFP under CAG promoter. Monoclonal cell lines selected by Puromycin were used for analysis. Each of the cell lines was cultured in doxycycline containing media for endogenous Oct4 knock-down. Pupose of this experiment is to investigate the possibility that forced expression of Nr5a2 can replace Oct4 function in the self-renewal of ES cells. Monoclonal ZHBTc4 ES cells expressing EGFP vs Nr5a2-EGFP, Oct4-EGFP vs Nr5a2-EGFP, no replication
