ChIP-seq of FLAG-tagged SMARCAD1 in female mouse embryonic stem cells (PGK12.1 XX)

ABSTRACT: To understand the role of the SWI/SNF-like ATP-dependent chromatin remodeller SMARCAD1 in pluripotent murine embryonic stem (ES) cells we determined the genome wide binding of triple FLAG tagged SMARCAD1 in PGK12.1 XX ES cells. ChIP was carried out using an antibody against the FLAG-epitope (F1804, Sigma) in double-cross linked chromatin. As controls, input samples and ChIP of PGK12.1 XX ES cells transfected with the empty triple-flag vector were used. The precipitated DNA was subsequently sequenced on an Illumina HiSeq1500.

ChIP-Seq of chromatin remodeler SMARCAD1 and H3K9me3 in female mouse embryonic stem cells (PGK12.1 XX)

Project description:Investigation of the co-occurance of the ATP-dependent chromatin remodeler SMARCAD1 and the histone modification H3K9me3 in the genome of PGK12.1 XX ES cells. ChIP-seq of endogenous SMARCAD1 was carried out in control and SMARCAD1-knockdown ES cells using a double crosslinking procedure. Additionally, H3K9me3 ChIP-seq was performed in double-cross linked control PGK12.1 XX cells. Input samples and precipitates with an IgG antibody were sequenced (Illumina HiSeq1500) as controls. Antibodies used were SMARCAD1 PAB15737 (Abnova) and H3K9me3 ab8898 (abcam).

Expression data from undifferentiated and differentiated mouse female ES cells PGK12.1

Project description:Affymetrix 430 2.0 mouse arrays were used for expression analyses in undifferentiated and differentiated PGK12.1 ES cells. We found that the X:autosome expression ratios calculated from the mean expression values of X-linked and autosomal genes from microarrays was ~1.4 in undifferentiated female ES cells and then decreased to 1.2 in PGK12.1 cells after 15-day embryoid body differentiation. Thus, a substantial level of X upregulation is already evident in these ES cells prior to differentiation. Our findings based on Affymetrix expression arrays are consistent with microarray analysis from other labs and our RNA-seq analysis of mouse female PGK12.1 ES cells. Mouse female ES cells PGK12.1 were differentiated by the EB (embryoid body) differentiation protocol. The presence of two active X chromosomes in undifferentiated female ES cells and one active X in 15-day differentiated cells was verified by Xist RNA FISH. Total RNA was prepared from undifferentiated and 15-day differentiated PGK12.1 and was used for expression array analyses to examine exprssion of the X chromosome during differentiation.

ChIP-Seq of SMARCAD1 and KAP1 in male mouse embryonic stem cells (E14)

Project description:The ATP dependent chromatin remodeler SMARCAD1 and the co-repressor KAP1 (Trim28/Tif1 beta) interact directly. We wanted to understand the interplay between these two proteins in the context of chromatin; in particular at repetitive sequences. Therefore, we carried out an investigation in E14 ES cells of the genome wide binding behaviour of KAP1 and FLAG-tagged SMARCAD1; both wild-type SMARCAD1 and a catalytically inactive mutant. The E14 cells analysed were either wild-type or depleted for endogenous SMARCAD1 protein. FLAG and KAP1 ChIP was performed on double-cross linked chromatin and sequenced on an Illumina HiSeq1500 with matched input controls. A FLAG antibody precipitation was carried out on cells not expressing FLAG tagged protein as an additional control.

Time-series of gene expression in female murine ES cells during EpiSC differentiation

Project description:Embryonic stem cells (ESC) are derived from the inner cell mass of the blastocyst in the presence of leukemia inhibitory factor (LIF). In vivo these cells then differentiate into epi stem cells (EpiSC) that can be derived from the Epiblast in presence of Fgf2 and ActivinA. In this study, female ESCs cultured in 2i medium have been differentiated into EpiSC for 3.5 days in vitro by addition of Fgf2 and Activin A. The gene expression profile was analyzed every 4-12 h using mouse exon arrays. Mouse Pgk12.1 ES cells were differentiated into EpiSC, samples were taken every 4-12 hours for 84 hours in total

Genome-wide binding profiles of Sp5 in differentiation mouse embryonic stem cells

Project description:We have determined the genome-wide binding profile of the transcription factor Sp5. Flag-tagged Sp5 was targeted to the HPRT locus in A2Lox.cre ES cells to allow for Doxycycline inducible expression. ES cells were cultured as embryoid bodies for 2 days to prime them for germ layer differentiation. Cells were then treated with Doxycycline for 24 hrs. We found that Flag-Sp5 prefentially bound to promoters associatd with several growth factor signalling pathways, but most prominently with the Wnt/beta-catenin pathway to selectively promote mesoderm differentiation over neural. These data implicate Sp5 as new regulator of Wnt/beta-catenin target expression to promotes ES cell differentation into the mesoderm lineage. Examination of Sp5 transcription factor binding in differentiating embryonic stem cells.

Expression data from mouse ES cells after control RNAi (scramble siRNAs) or specific RNAi (siRNAs for specific genes) treatment

Project description:To address the functional role of MOF in mammalian X upregulation, male and female mouse ES cells were transfected with a mixture of three small interfering RNA duplexes, each of which targets a different region of Mof mRNA. We found that MOF knockdown in mouse ES cells caused a greater drop in expression of X-linked genes compared to autosomal genes, as measured by expression array analyses. The strongest effect was observed on medium-expressed X-linked genes. We next examined components of the two known MOF protein complexes, MSL1 (male-specific lethal1) and NSL1 (nonspecific lethal1). Knockdown of MSL1 but not NSL1 in undifferentiated female ES cells PGK12.1 specifically caused a decrease in expression levels of X-linked genes. Cells co-transfected with both MOF and MSL1 siRNAs had similar expression changes to MSL1 knockdown alone, indicating that these components probably operate within the same complex but are not additive. Our findings that key components of the MSL but not NSL complex play a role in upregulation of mammalian X-linked genes in ES cells. Mouse ES cells were treated by Invitrogen scramble siRNA duplexes or specific siRNA duplexes and used for RNA extraction and hybridization on Affymetrix microarrays. Six RNA samples from two independent double-RNAi treatments and one single-RNAi treatment in undifferentiated female ES cells PGK12.1, and RNA samples from two single-RNAi treatments in undifferentiated male ES cells WD44 or E14 were assayed for expression changes by arrays. RNA samples from three MSL1RNAi treatments, two MOF/MSL1RNAi treatments and three NSL1RNAi treatments in undifferentiated female ES cells PGK12.1 were assayed by arrays.

Determination of the Lef1 regulated tanscriptome in differentiating ES cells

Project description:Lef1 is a critical transducer of the Wnt/beta-catenin signaling pathway that is essential for mesoderm differentiation in vertebrate embryos. We established a doxycycline inducible ES cell line to over-express Flag-tagged Lef1 in differentiating ES cells which have the capacity to form mesoderm cells in vitro. The goal of this study was to identify the genes/gene networks regulated by Lef1 to understand how it regulates mesoderm differentiation and to establish the Lef1-regulated, Wnt/beta-catenin transcriptome. Total RNA was extracted from ES cells after 3 days of differentiating following Lef1 over-expression from day 2 to 3. We compared the transcriptome of differentially expressed genes in untreated and doxycycline treated ES cells to identify Lef1 regulated genes.

Determination of the Sp5 regulated transcriptome in differentiating ES cells

Project description:Sp5 is a target and critical transducer of the Wnt/beta-catenin signaling pathway and is essential for mesoderm differentiation in vertebrate embryos. We established a doxycycline inducible ES cell line to over-express Flag epitope-tagged Sp5 protein in differentiating ES cells which have the capacity to form mesoderm cells in vitro. The goal of this study was to identify the genes/gene networks regulated by Sp5 to understand how it regulates mesoderm differentiation by identifying important target genes which may mediate its activity. Total RNA was extracted from ES cells after 3 days of differentiating following F-Sp5 over-expression from day 2 to 3. We compared the transcriptome of differentially expressed genes between untreated (minus) and doxycycline treated (plus) ES cells to identify Sp5 regulated genes.
