(Submitter supplied) During oogenesis, DNA methyltransferase 3-like (Dnmt3l) is required for the establishment of the maternal germline DNA methylation imprints that in the offspring, govern the parent-of-origin-specific expression of most known imprinted genes (Science 2001, 294:2536-9). Dnmt3l-deficient dams were crossed with wildtype sires to obtain Dnmt3l-/+ embryos that lack maternal methylation imprints. Gene expression was measured in Dnmt3l-/+ and wildtype embryos and is expected to differ for imprinted genes that are under the control of a maternal methylation mark. more...

(Submitter supplied) We have combined high-quality genome sequencing and RNA-sequencing data within a 17-individual, three generation family. Using these data, we have contrasted cis-acting expression, allele-specific expression and splicing quantitative trait loci (collectively termed eQTLs) within the family to eQTLs discovered within a cell-type and ethnicity-matched population sample. We identified that eQTL that exhibit larger effects in the family compared to the population are enriched for rare regulatory and splicing variants and were more likely to influence essential genes. more...

(Submitter supplied) Specific 50-mer oligonucleotides synthesized by Operon were resuspended in 150 mM phosphate buffer pH 8.3 at a concentration of 20 micromoles. For each gene, two different oligonucleotide probes, one corresponding to the 3’ non-coding region and one corresponding to the coding region were designed. The resulting application targeted microarray contained 992 gene-specific oligonucleotide probes generated from 63 imprinted genes and 15 genes encoding proteins involved in epigenetic marking (BORIS, brother of regulatory imprinting sequence, 5 DNMT, DNA methyltransferases and 9 HDAC, histone deacetylases), as well as 256 genes encoding proteins involved in neurotransmission and 157 genes encoding proteins involved in energy homeostasis. more...

(Submitter supplied) Utilizing reciprocal genome-wide uniparental disomy samples presenting with Beckwith-Wiedemann and Silver-Russell syndrome-like phenotypes, we have analyzed ~0.1% of CpG dinucleotides present in the human genome for imprinted differentially methylated regions (DMRs) using the Illumina Infinium HumanMethylation27 BeadChip microarray. This approach identified 15 imprinted DMRs associated with previously characterized imprinted domains, and confirmed the maternal methylation of the RB1 DMR. more...

(Submitter supplied) Many questions about the regulation, functional specialization, computational prediction, and evolution of genomic imprinting would be better addressed by having an exhaustive genome-wide catalog of genes that display parent-of-origin differential expression. As a first-pass scan for novel imprinted genes, we performed mRNA-seq experiments on E17.5 mouse placenta cDNA samples from reciprocal cross F1 progeny of AKR and PWD mouse strains, and quantified the allele-specific expression and the degree of parent-of-origin effect transcriptome-wide. more...

(Submitter supplied) Bisulphite (BS) converted DNA from 2 paternal uniparental diploidies (pUPDs), one maternal (mUPD) and 5 control leukocytes samples were hybridized to the Infinium HumanMethylationEPIC BeadChip (Illumina), obtaining the BS DNA methylation profiles across approximately 850,000 CpGs. In addition, the 5 control leukocyte samples were also coverted using oxidative bisulphite (oxBS) treatment. The selective chemical oxidation of 5-hydroxymethylcytosine (5hmC) to 5-formylcytosine (5fC) and the deamination of the latter to uracil during the BS conversion allowed the quantification of independent 5-methylcytosine (5mC) and 5hmC methylation levels at every single CpG.

(Submitter supplied) Parthenogenetic embryonic stem cells (PESCs) may have future utility in cell replacement therapies. We examined genome-wide mRNA expression profiles of monkey PESCs relative to ESCs derived from fertilized embryos. Several known paternally-imprinted genes were in the highly down-regulated group in PESCs compared to ESCs. Allele specific expression analysis of paternally-imprinted genes, i.e., those genes whose expression is down-regulated in PESCs, led to the identification of one novel candidate that was exclusively expressed from a paternal allele. more...

(Submitter supplied) Genomic imprinting, resulting in parent-of-origin specific gene expression, plays a critical role in mammalian development. Here, we perform allele-specific RNA-Seq on isogenic B6D2F1 mice to assay imprinted genes in tissues from early embryonic stages and in pluripotent cell lines. For the cell lines, we include embryonic stem cells (ESCs) and epiblast stem cells (EpiSCs) derived from fertilized embryos or from embryos obtained after nuclear transfer (NT), as well as B6D2F1 ESCs and EpiSCs derived after parthenogenetic activation (PGA). more...

(Submitter supplied) During early mammalian development transient pools of pluripotent cells emerge that can be immortalised upon stem cell derivation. The pluripotent state, "naïve" or "primed", depends on the embryonic stage and derivation conditions used. Here we analyse the temporal gene expression patterns of mouse, cattle and porcine embryos at stages that harbour different types of pluripotent cells. We document conserved and divergent traits in gene expression, and identify predictor genes shared across the species that are associated with pluripotent states in vivo and in vitro Amongst these are the pluripotency-linked genes Klf4 and Lin28b The novel genes discovered include naïve- (Spic, Scpep1 and Gjb5) and primed-associated (Sema6a and Jakmip2) genes as well as naïve-to primed transition genes (Dusp6 and Trip6). more...

(Submitter supplied) Genomic imprinting is an epigenetic phenomenon by which certain genes display differential expression in a parent-of-origin-dependent manner. Hundreds of imprinted genes have been identified from several plant species. Here we identified, with a high level of confidence, 208 imprinted candidates from rice. Imprinted genes of rice showed limited association to the transposable elements, which contrasts with findings from Arabidopsis. more...

(Submitter supplied) Parent-of-origin dependent expression of alleles, imprinting, has been suggested to impact a substantial proportion of mammalian genes. Its discovery requires allele-specific detection of expressed transcripts, but in some cases detected allelic expression (AE) bias has been interpreted as imprinting without demonstrating compatible transmission patterns and excluding heritable variation. Therefore, we utilized a genome-wide tool exploiting high density genotyping arrays in parallel measurements of genotypes in RNA and DNA to determine AE across the transcriptome in lymphoblastoid cell lines (LCLs) and skin fibroblasts derived from families.

(Submitter supplied) The discovery of genomic imprinting through studies of manipulated mouse embryos indicated that the paternal genome has a major influence on placental development. However, previous research has not demonstrated paternal bias in imprinted genes. We applied RNA sequencing to trophoblast tissue from reciprocal hybrids of horse and donkey, where genotypic differences allowed parent-of-origin identification of most expressed genes. more...

(Submitter supplied) The maternal and paternal genomes play different roles in mammalian brains as a result of genomic imprinting, an epigenetic regulation leading to differential expression of the parental alleles of some genes. Here we investigate genomic imprinting in the cerebellum using a newly developed Bayesian statistical model that provides unprecedented transcript-level resolution. We uncover 160 imprinted transcripts, including 41 novel and independently validated imprinted genes. more...

(Submitter supplied) Several hundred mammalian genes are expressed preferentially from one parental allele due to a process called genomic imprinting. Genomic imprinting is particularly prevalent in extra-embryonic tissue, where it plays an essential role during development. Here, we profiled imprinted gene expression via RNA-Seq in a panel of six mouse trophoblast stem (TSC) lines, which are ex vivo derivatives of a progenitor population that gives rise to the placental tissue of the mouse. more...
