  1. ...). In early mouse embryos, imprinted XCI (iXCI), which always inactivates the paternal X Chromosome, takes place at the four-cell stage. It is followed by XCR, in the inner cell mass (ICM) of the blastocyst (Mak et al. 2004; Okamoto et al. 2004; Borensztein et al. 2017a, b). Then, random XCI (rXCI) of one...
  2. ...degree of coverage in each sample. (D) Principal component analysis (PCA) of HCC827, MCF7, and SKBR3 single-cell transcriptomes. Genes used in PCA are identified in Supplemental Figure S11A. RNA-seq data of both WRs and FRs single cells from each cell line clustered together. (E) Genomic snapshots of cDNA...
  3. ...). We then trained two Random Forest machine-learning models to predict from 77 genomic and epigenetic features (1) whether a gene is subject to XCI, and (2) whether it will be silenced with fast or slow kinetics. Through forest-guided gene clustering, we identified feature sets that determine...
  4. ..., clustered parental imprinting of protein-coding and noncoding RNAs in developing maize endosperm. Proc Natl Acad Sci 108: 20042–20047. ↵Zhang M, Xie S, Dong X, Zhao X, Zeng B, Chen J, Li H, Yang W, Zhao H, Wang G, et al. 2014. Genome-wide high resolution parental-specific DNA and histone methylation maps...
  5. ...hypomethylation, DNA hypermethylation of CpG islands (CGIs) is a well-defined feature of cancer cells and is believed to be the main cause of aberrant gene repression (Baylin and Jones 2016). CGIs are key regulatory genomic regions of a few hundred base pairs in size characterized by high frequency of Cp...
  6. ...system, a random DNA sequence known as amolecular barcode is inserted into the 3′ UTR of the reporter gene, and a library of candidate regulatory elements are placed upstream of the promoter. Each individual candidate regulatory element is physically linked to a unique molecular barcode. Measuring...

  7. ...The Jackson Laboratory, Bar Harbor, Maine 04609, USA In this issue, Sano et al (2001) describe a cluster of three genes in the mouse t complex that exhibit random monoallelic expression, representing a new example of somatic mosaicism. These findings are fascinating from several perspectives, raising...
  8. ...DNA from each case were labeled by random priming using Cy5 and Cy3-conjugated randomnonamers (TriLink BioTechnologies), and hybridized to tiling oligonucleotide arrays. We used arrays composed of 2.1 million 50-mer to 75-mer oligonucleotides covering chromosomes 20, 21, 22, X, and Y at amedian probe...
  9. ...) (Meg3 and H19), we showed that Igf2r, Meg3, and H19 were monoallelically expressed irrespective of the proliferation status of the cells (Fig. 3E). We then tested whether the proliferation status of MEFs influenced the DNA methylation pattern at imprinted loci. We treated genomicDNA fromproliferating...
  10. ...with the probability determined by the random trials. (F) DCA genes were compared to 1000 randomized gene sets for the number within 50 kb of known imprinted genes. Kelly et al . 2502 Genome Research www..org Discussion Using a novel approach to examine nucleosome occupancy and endogenous DNA methylation -wide, we...
