Project description:Polycomb repressive complexes (PRCs) are important chromatin regulators of ES cell function. RYBP binds Polycomb H2A monoubiquitin ligases Ring1A and Ring1B, and has been suggested to participate in localizing Polycomb complexes to their targets. Moreover, constitutive inactivation of RYBP precludes ES cell formation. Here we have used ES cells conditionally deficient in RYBP to investigate RYBP function. Chromosome immunoprecipitation on a chip (ChIP-chip) of RYBP and microarray experiments were performed using wild type and knocked-out ES cells. Gene expression profiling of WT, conditionally deficient in RYBP with or without Yaf2 RNAi, and ChIP-chip of RYBP on promoters of WT, Dnmt1-KO or Eed-KO ES cells.

Project description:We used microarrays to investigate a global change in gene expression by conditional depletion of Rybp in mouse ES cells. Total RNAs were extracted from wild-type and Rybp-deficient ES cells, and were subjected to microarray analysis using Affymetrix GeneChip Mouse Genome 430A 2.0 arrays
Project description:To study effect of VRK1 deletion on spermatogenesis of the mouse, transciptomic analysis of genes in postnatal 8-day testicular cells of wild type and VRK1-deficient Mus musculus was performed.
