ABSTRACT: ChIP-seq after immunoprecipitation with either IgG or SOX2 antibodies in murine genetically modified stem cells overexpressing the RAX gene (CCE-Rx cells)
Project description:SOX2 is the main gene involved in anophthalmia. In order to identify genes regulated by SOX2 transcription factors (genes that could be good candidates to also be involved in ocular development), we studied transcriptomic profiles of murine genetically modified stem cells overexpressing the RAX gene (CCE-Rx cells) after transfection by a siRNA against SOX2 or a scramble siRNA. murine genetically modified stem cells overexpressing the RAX gene (CCE-Rx cells) after transfection by a siRNA against SOX2 or a scramble siRNA
Project description:In order to identify target genes of the SOX2 transcription factor, we tried to identify SOX2 binding site in murine genetically modified stem cells overexpressing the RAX gene (CCE-Rx cells) by ChIP-seq. SOX2 gene mutations are involved in anophthalmia and our hypothesis was that target genes of SOX2 transcription factor may also be candidate to be involved in ocular development. High throughput sequencing after chromatin immunoprecipitation using either an antibody against our target transcription factor (SOX2) or using control antobodies (IgG). These experiments were performed on only one immunoprecipitation with each antibody.

Project description:Embryonic stem (ES) cells have a remarkable capacity to self-organize complex, multi-layered optic cups in vitro via a culture technique called SFEBq. During both SFEBq and in vivo optic cup development, Rax (Rx) expressing neural retina epithelial (NRE) tissues utilize Fgf and Wnt/β-catenin signalling pathways to differentiate into neural retina (NR) and retinal-pigmented epithelial (RPE) tissues, respectively. How these signaling pathways affect gene expression during optic tissue formation has remained largely unknown, especially at the transcriptome scale. We generated Day 10 Rx+ optic tissue using SFEBq, exposed these tissues to either Fgf or Wnt/β-catenin stimulation, and assayed their gene expression at Days 12 and 15 using RNA-Seq. We measured gene expression in these 5 sample groups in biological triplicate using RNA-seq (Illumina HiSeq) .
Project description:To gain insight into the specificity of target mRNAs, we enriched mRNAs bound to TRS by immunoprecipitation with anti-TRS antibody, then performed RNA immunoprecipitation and sequencing (RIP-seq) and compared the mRNAs with those enriched by immunoprecipitation with IgG, anti-AlaRS, anti-PRS and anti-IRS antibodies.

Project description:To identify the MYCN transcription factor binding sites across the genome, we performed chromatin immunoprecipitation followed by sequencing (ChIP-seq) using anti-MYCN and anti-IgG antibodies on a MYCN-amplified NB cell line, SK-N-BE(2)-C.
