Project description:To investigate the function of VCP in the colorectal cancer progression, we established HCT116 cell lines overexpressing VCP. We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 different cells overexpressing VCP and control vector.
Project description:Carboxy-terminally tagged MOZ (Flag-V5-BIO tagged) was detected by ChIP-seq using anti-V5 antibody (Sigma, A7345) to precipitate chromatin associated with MOZ
Project description:To investigate the signaling patheway of VCP regulation PD-L1 in colorectal cancer cells, HCT116 cells were treated with CB-5083. We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 different cells CB-5083 treatment and untreatment.
Project description:Isolation of IMP1 bound mRNAs. Flag-tagged IMP1 was expressed in HEK293 cells. Flag tagged IMP1 was immunoprecipitated and mRNAs isolated. As controls HEK293 cells that do not express Flag-tagged IMP1 was included.
Project description:In order to assess Tet1 binding, we first generated a Flag tagged Tet1 ES cells and then knocked out Dnmt3a in the [WT, Tet1-Flag] cells. By Tet1 ChIP and Flag ChIP, we showed that Tet1 binding was complementary to Dnmt3a. And Tet1 binding was not affected or slightly increased at majority of its targets.
Project description:RNA-sequencing of H3.3-G34R and H3.3-WT HGG cells was performed to uncover transcriptomic differences related to the presence of H3.3-G34R mutation, using human cells obtained from a patient harboring pHGG and stably tranfected with 3X-FLAG-tagged wild type H3.3 or a 3X-FLAG-tagged H3.3 harboring the G34R mutation.
Project description:NIPP1, an established interactor of protein phosphatase 1 (PP1), is implicated in PRC2-mediated regulation of gene expression. Here, we explore whether PP1 associated with NIPP1 is involved in NIPP1-mediated regulation of genes. Therefore, we generated Hela Tet-off (HTO) cell lines that stably and inducibly express a Flag-tagged version of wild-type NIPP1 (HTO-NIPP1wt) or mutant NIPP1 (HTO_NIPP1m). The latter mutant lacks the major PP1 binding site by two point mutations in the RVXF-motif, an established PP1 - binding motif. All cell lines were derived from the same parental HeLa Tet-Off (HTO-PT) cell line which expresses only tTA transactivator and is used as a control. The Flag fusions were only expressed in the absence of doxycyline and at levels that were up to twofold higher than that of endogenous NIPP1. We performed a gene expression profiling of the HTO cell lines, using Whole Human Genome Oligo microarrays from Agilent. A Paired SAM analysis identified 1365 genes with an altered expression (P < 0.01) between the Flag-NIPP1 and parental cell lines. Importantly, only 185 genes were differentially expressed (P<0.01) between the Flag-NIPP1m and parental cell lines. Even more strikingly, only 5% of the genes that were affected by the expression of Flag-NIPP1 also showed a significantly different expression in the Flag-NIPP1m cells. A similar small overlap was noted when the analysis was restricted to the 50 genes that were most upregulated or downregulated by the expression of Flag-NIPP1. Finally, scatter plot analysis revealed no significant correlation between the genes that were affected by the expression of Flag-NIPP1 or Flag-NIPP1m. Collectively, these data demonstrate that a moderate increase in the concentration of NIPP1 affects the expression of numerous genes by a mechanism that depends on associated PP1.
