Project description:Purpose:The goals of this study are to understand the mechanisms underlying reduced self-renewal and loss of pluripotency by depletion of Rif1. Methods: We performed global gene expression analysis of Rif1 knockdown ES cell lines using Affymetrix 430 2.0 arrays, compared to shRNA controls. J1 ES cells were transfected with Control shRNA and Rif1 shRNA using lipofectamine 2000. Forty-eight hours after transfection, cells were collected for global gene expression analysis using Affymetrix mouse genome 430 2.0 array. Stable F1 Rif1 knockdown ES cells at passage 16 were used for long-term gene expression chip microarray using Affymetrix mouse genome 430 2.0 array.
Project description:Multiple protein complexes and histone marks have been implicated and/or associated with gene repression in ES cells. To gain insights into repressive complexes present at repressed genes and their associated chromatin state, we profiled REST, MCAF1, Ring1b and H4K20me3 in mouse ES cells.
Project description:Multiple protein complexes and histone marks have been implicated and/or associated with gene repression in ES cells. To gain insights into repressive complexes present at repressed genes and their associated chromatin state, we profiled REST, MCAF1, Ring1b and H4K20me3 in mouse ES cells. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. ChIP was performed using an antibody against REST, MCAF1, Ring1b and H4K20me3.
Project description:Transcriptional profiling of R1 mouse ES cells infected with non-targeting control (NTC) shRNA and two different shRNA sequences against Cdk8 (shCdk8-1 and shCdk-2) and Med12 (shMed12-1 and shMed12-2).
Project description:TET-family enzymes convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) in DNA. Tet1 and Tet2 are Oct4-regulated enzymes that together sustain 5hmC in mouse embryonic stem (ES) cells. ES cells depleted of Tet1 by RNAi show diminished expression of the Nodal antagonist Lefty1, and display hyperactive Nodal signalling and skewed differentiation into the endoderm-mesoderm lineage in embryoid bodies in vitro. In Fgf4- and heparin-supplemented culture conditions that favor derivation of trophoblast stem (TS) cells, Tet1-depleted ES cells activate the trophoblast stem cell lineage determinant Elf5 and can colonize the placenta in mid-gestation embryo chimeras. Consistent with these findings, Tet1-depleted ES cells form aggressive hemorrhagic teratomas with increased endoderm, reduced neuroectoderm and ectopic appearance of trophoblastic giant cells. Thus Tet1 functions to regulate the lineage differentiation potential of ES cells. Here, we performed whole-genome transcriptome profiling of ES cells stably depleted of Tet1 by shRNA knockdown (Tet1-kd) cultured in either standard ES cell or in TS cell culture conditions. Gene expression changes in Tet1-kd ES cells were fairly modest compared to control (GFP-kd) cells, although gene ontology (GO) analysis of differentially expressed genes yielded many terms related to embryonic development and cell cycle regulation. In TS cell culture conditions, a core set of genes defining trophectodermal cell differentiation, including Cdx2, Eomes and Tead4, was enriched in Tet1-kd compared to GFP-kd cells.
