RNA-seq in Smchd1 wild-type and Smchd1 null presomitic mesoderm from E9.5 embryos

Project description:We sought to examine whether the non-canonical SMC protein Smchd1 plays a role in chromosome conformation. We used in situ Hi-C to analyse chromosome conformation changes upon deletion of the epigenetic regulator Smchd1 in female neural stem cells. In parallel, we analysed nucleosome accessibility using ATAC-seq, gene expression using RNA-seq, chromatin marks H3K27me3 and H3K27ac and Ctcf binding using ChIP-seq. We additionally analysed Smchd1 binding genome-wide using ChIP-seq. Together, we find that deletion of Smchd1 alters chromosome conformation at Smchd1 target genes including the inactive X chromosome, Hox genes and imprinted loci. Smchd1 deletion in differentiating ES cells results in failed Hox gene silencing and Smchd1 null E9.5 embryos show altered Hox gene expression.. Smchd1 deletion results in gain in Ctcf binding and activation of enhancers. We propose Smchd1 functions by limiting Ctcf-mediated chromosome looping.

The effect on gene expression of Smchd1 deletion in pre-B cells from E17.5 Eµ-Myc embryos

Project description:Smchd1 appears to act as a tumour suppressor in the Eµ-Myc mouse B cell lymphoma model. We find a small number of gene expression differences at E17.5 in the pre-B cells, before phenotypic differences are observed. The microarrays compared Smchd1 null and Smchd1 wildtype E17.5 preB cell samples. All samples are on the C57BL/6 background and carry the Eµ-Myc transgene, and the Smchd1 null samples are additionally homozygous for a Smchd1 genetrap allele.

The effect on gene expression of Smchd1 deletion in premalignant pre-B cells

Project description:Smchd1 appears to act as a tumour suppressor in the Eµ-Myc B cell lymphoma model. We find gene expression differences are most pronounced in premalignant cells. We always detect a small number of clustered genes and imprinted genes as differentially expressed, along with others involved in tumorigenesis. The microarrays compared Smchd1 null and Smchd1 wildtype samples from premalignant pre-B cells. All samples are on the C57BL/6 background, and carry the Eµ-Myc transgene. Smchd1 null samples are additionally homozygous for a Smchd1 genetrap allele.

The effect on gene expression of Smchd1 deletion in end stage lymphomas

Project description:Smchd1 appears to act as a tumour suppressor in the Eµ-Myc B cell lymphoma model. We find gene expression differences are most pronounced in the premalignant cells, and observe more variability in end stage lymphomas. We always detect a small number of clustered genes and imprinted genes as differentially expressed, along with others involved in tumorigenesis. The microarrays compared Smchd1 null and Smchd1 wildtype samples from end stage lymphomas. All lymphomas are on the C57BL/6 background and carry the Eµ-Myc transgene, and Smchd1 null samples are additionally homozygous for a Smchd1 genetrap allele.

Transcription profiling of mouse E10.5 female embryos wild-type and mutant for Smchd1

Project description:To investigate the role of the Smchd1 protein in epigenetic silencing of autosomal loci, we carried out a comparative microarray gene expression analysis of wild-type and Smchd1-/- female embryos at E10.5. Embryos were collected at E10.5 after natural mating, sexed and genotyped. Total RNAs were extracted from three individual wild-type and three Smchd1-/- female embryos and cRNAs prepared from these samples was hybridized to Affymetrix GeneChip Mouse Genome 430 2.0 array.
