Expression data from Rbp2f/f and Rbp2-/- ES cells before and after differentiation

ABSTRACT: Aberrations in epigenetic processes, such as histone methylation, can lead to cancer. Retinoblastoma Binding Protein 2 (RBP2)(also called JARID1A or KDM5A) can demethylate tri- and di-methylated lysine 4 in histone H3, which are epigenetic marks for transcriptionally active chromatin, whereas the MEN1 tumor suppressor promotes H3K4 methylation. Previous studies suggested that inhibition of RBP2 contributed to tumor suppression by pRB. Here we show RBP2 loss promotes cellular differentiation in vitro. We use mouse expression array 430 2.0 array to profile gene expression patterns of Rbp2f/f and Rbp2-/- ES cells in ES cell medium and after 6 days in ES cell medium without LIF. Subconfluent Rbp2f/f and Rbp2-/- ES cells in ES cell medium and after 6 days in ES cell medium without LIF were harvested for RNA isolation using RNeasy mini kit with on-column DNase digestion (Qiagen). Gene expression profiling was performed using Affymetrix GeneChip mouse genome 430 2.0 arrays. Duplicate samples were used

The Retinoblastoma Binding Protein RBP2 is an H3K4 demethylase

Project description:The roles of histone demethylase RBP2 in gene expression were assessed using gene expression profiling experiments with wild type and RBP2-/- primary MEFs. Several cytokine genes including SDF1 and Kit ligand were upregulated upon inactivation of RBP2. Keywords: mouse embryonic fibroblasts, gene expression profiling, microarray, Affymetrix Mouse Genome 430 2.0, cell type comparison

Genome-wide maps of KDM5A/JARID1A/RBP2 and JARID2/JMJ in HL-1 cardiomyocytes.

Project description:We report the identification of genomic regions bound by RBP2 and JARID2 in mouse cardiomyocytes. RBP2 generates methylated lysine 4 in histone H3. Consistent with previous data, RBP2 binds at the TSS regions. However, we found that overepresentation of gene ontologies (GO) for RBP2 targets in cardiomyocytes is drastically different from those in mouse embryonic stem (ES) cells. In cardiomyocytes, there is overepresentation of genes involved in heart morphogenesis and vasculogenesis. Strikingly, we found that location of JARID2, a factor critical for ES cell function, significantly overlaps with RBP2 location in cardiomyocytes.

Changes in H3K4 methylation in KDM5A/JARID1A/RBP2 knockout cells.

Project description:We sought to determine H3K4me3 distribution in mouse embryonic stem (ES) cells deficient for RBP2 compared with wild-type cells. RBP2 modifies methylated lysine residues on histone tails. As a result of this analysis, we identified genomic regions with changed H3K4me3 status and described these in gene ontology (GO) categories.

Expression data in H1299 after retinoblastoma binding protein-2 (RBP2) knockdown

Project description:To identify genes whose expression was affected by RBP2, we performed gene expression microarray analysis in control and RBP2 depletion human lung cancer cell line. Two individual shRNA (RBP2 KD1 and RBP2 KD2) were used to limit potential off-target effects.

SAOS-2 cells, RBP2 knockdown or pRB overexpression

Project description:RBP2 is downstream of pRB pathway We used gene expression profiling experiments to investigate if gene expression changes in cells with RBP2 knockdown significantly overlap with gene expression changes in cells overexpressing pRB, consistent with the data that knockdown of RBP2 phenocopies reintroduction of pRB in SAOS-2 (RB-/-) cells Keywords: epistatic experiment

RBP2 location analysis

Project description:RBP2 (JARID1A/RBBP2) enrichment at proximal promoter regions in differentiating promonocytic U937 cells and in the osteosarcoma SAOS-2 cells Keywords: differentiation treatment, ChIP-on-chip analysis We sought to determine transcriptional regulation by RBP2 genome-wide by using location analysis. We describe that RBP2 target genes are separated into two functionally distinct classes: differentiation independent and differentiation dependent genes.Three condition experiment, U937 cells treated with 100 nM 12-O-tetradeconoyl-phorbol 13-acetate (TPA) (Sigma) for two different time points (27 hrs and 96 hrs) and untreated (0 hrs time point or no TPA treatment). In addition, processed data for the unrelated SAOS-2 cells are included. Biological replicates: threechromatin immunoprecipitations (ChIP) performed independently in parallel

Effect of RBP2 on MCF7 breast cancer cells (RNA-seq)

Project description:RNA-sequencing analysis of RBP2 overexpressing MCF7 cell lines. RBP2 (also known as JARID1A), a member of the JARID1 family of histone H3 lysine K4 demethylases, has been considered to have an oncogenic potential in several cancer including breast cancer. Results provide insight into the transcriptional regulation of RBP2 in estrogen receptor positve breast cancer.
