  1. ...of the fifth carbon atom of cytosine, typically in mammals in a CG dinucleotide context. This dinucleotide is depleted largely across the and found predominantly in clusters known as “CpG islands” (Bird 1986). Cytosine methylation is catalyzed by methyltransferases (e.g., DNMT1, DNMT3A) that transfer a methyl...

  2. ...-specific expression of imprinted Kcnq1 was determined by different NlaIII digestion patterns based on the SNP between mus and cas. H2A.B and methylated CpG Genome Research 573 www..org Fig. S6E). Of note, the transcription of Kcnq1 was only from the maternal allele since Kcnq1ot1, transcribed from the paternal allele...
  3. ..., with the portion of the corresponding to regions of CTCF binding. We found that methylation at CpG dinucleotides appears to have a greater influence on CTCF binding than non-CpG methylation. Genome wide, 60.8% of CpGs are methylated in the mouse brain, in contrast to 51.9% of CpGs in regions of CTCF binding. NonCpG...
  4. ...).Identification of novel imprinted placental DMRsWe sought to identify novel imprinted DMRs by identifying CpG islands (CGIs) that showed a profile consistent with imprinting in early human development: DMRs that were both differentially methylated in the germline and between triploid placental samples. First, CGIs...
  5. ...and maternally expressed. Increased maternal transmission of male homosexuality has previously been observed ( Hamer et al. 1993 ), and it is proposed to result in part from imprinted genes ( Bocklandt and Hamer 2003 ). A -wide screen for methylated CpG islands found a germline differentially methylated region...
  6. ...for the utility of comparing -wide methylation profiles for genomic regions of uniparental versus biparental origin to identify new DMCpG sites associated with known imprinted genes as well as new candidate imprinted genes. To identify novel DMCpG sites, we screened the 26,486 autosomal CpG sites represented...
  7. ...,165) and display the same pattern, while methylated CpG island promoters (781) are nucleosome-occupied and inaccessible to M.CviPI. (D) NonCpG island promoters are generally characterized by CpG methylation and inaccessibility to M.CviPI, indicating nucleosome occupancy. The few unmethylated non-CpG island...
  8. ...) and CpG Island Clones Isolated in a Methylation-Sensitive Representational Difference Analysis (Me-RDA) Screen for Maternal Methylation Nap1l5 , a Novel Imprinted Gene on Chr 6 Encoding a Protein With Homology With NAPs We isolated DPC#24–1, a 449-bp fragment from the Hin 6I Me-RDA that maps to Chr 6...
  9. ...and the expression of imprinted genes (Feinberg 2004). Locus-specific hypermethylation occurs primarily in CpG islands that are often associated with gene regulatory regions. This, in turn, can lead to transcriptional inactivation of downstream gene(s), followed by changes in cellular functions. In cancer cells...
  10. ...In addition to the known imprinted DMRs, the Infinium array screen of reciprocal UPDs and tissues samples uncovered several previously unidentified DMRs located within existing imprinted domains. We discovered four maternally methylated CpG islands located between the SNRPN and NDN genes on chromosome 15...
