H3K36me3 protects the mouse epigenome from single nucleotide variations [CGH]
Ontology highlight
ABSTRACT: Copy numbers of mouse cells (ESCs and NIH3T3) carrying a series of single-site histone mutants or shRNAs comparing with control empty cells. Genomic DNA from candidate cells and control cells were respectively labeled by Cy5 or Cy3 and analyzed by array-based comparative genomic hybridization (aCGH).
Project description:Comparison of normal versus tumor DNA (hepatocellular carcinoma). Whole-genome screening of DNA-copy number changes by array-based or matrix comparative genomic hybridization (aCGH). Tumor DNA labeled in Cy3 and pooled DNA of lymphocytes from healthy donors labeled in Cy5. Keywords: Genetic modification
Project description:We adopt histone H3 mutants competitive incorporation system to screen the effects of them on genetic fidelity. We find incorporation of H3K36M, an oncogenic histone mutant, produce a cancer or ageing-like genetic landscape by punctuating the H3K36me3/H3K9me3 dependent DNA repair mechanism. This work firstly get a direct relationship between epigenetic inheritance and genomic stability
Project description:We analyze high-throughput profiling of histone H3K36me3 in mouse embryonic stem cells from chromatin immunoprecipitated DNA captured by H3K36me3-specific antibody. We find that H3K36me3 distribution is like expected and enriched at transcribing gene bodies especially with enrichment at 3’-terminal of gene body, which is identical with findings observed in other mammalian cells.
Project description:The goals of this project are to study the transcriptome profiling (RNA-seq) of mouse embryonic stem cells by histone mutants incorporation (H3.1K3M, H3.1K36M vs H3.1wt) or shRNA-mediated knockdown of methyl-transferase Suv39h1/h2 (shSuv39h1, shSuv39h2 vs shNC)
Project description:We performed array comparative genomic hybridization (aCGH) for our hybrid cells. All two analyzed hybrid ES cell liness were chromosomally stable.
Project description:To test genome stability of the parthenogenetic haploid embryonic stem cells, we performed array comparative genomic hybridization (aCGH) analysis.
Project description:DNA copy-number profiling of 80 primary medulloblastomas of different histologies Keywords: Genetic modification Comparison of tumor DNA (medulloblastoma) versus control DNA (pool of lymphocyte DNA from 10 healthy donors). Whole-genome screening for DNA copy-number aberrations using array-based comparative genomic hybridization (aCGH). Tumor DNA labeled in Cy3 and control DNA labeled in Cy5.
Project description:A CNV map in pigs could facilitate the identification of chromosomal regions that segregate for important economic and disease phenotypes. The goal of this study was to identify CNV regions (CNVRs) in pigs based on a custom array comparative genome hybridization (aCGH). We carried out a custom-made array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the pig genome analysing animals of diverse pig breeds (White Duroc, Yangxin, Erhualian, Tongcheng, Large White, Pietrain, Landrace and Chinese new pig line DIV ) using a tiling oligonucleotide array with ~720,000 probes designed on the pig genome (Sus scrofa genome version 9.0).
Project description:DNA copy-number profiling of 73 T-ALLs Keywords: Genetic modification Comparison of tumor DNA (tumor) versus control DNA (pool of lymphocyte DNA from 10 healthy donors). Whole-genome screening for DNA copy-number aberrations using array-based comparative genomic hybridization (aCGH). Tumor DNA labeled in Cy3 and control DNA labeled in Cy5.
Project description:DNA copy-number profiling of 66 astrocytomas of WHO °I or °II Comparison of tumor DNA (tumor) versus control DNA (pool of lymphocyte DNA from 10 healthy donors). Whole-genome screening for DNA copy-number aberrations using array-based comparative genomic hybridization (aCGH). Tumor DNA labeled in Cy3 and control DNA labeled in Cy5.
