Abstract:
Abstract Parent-of-origin methylation arises when the methylation patterns of a particular allele are dependent on the parent it was inherited from. Previous work in honey bees has shown evidence of parent-of-origin-specific expression, yet the mechanisms regulating such pattern remain unknown in honey bees. In mammals and plants, DNA methylation is known to regulate parent-of-origin effects such as genomic imprinting. Here, we utilize genotyping of reciprocal European and Africanized honey bee crosses to study genome-wide allele-specific methylation patterns in sterile and reproductive individuals. Our data confirm the presence of allele-specific methylation in honey bees in lineage-specific contexts but also importantly, though to a lesser degree, parent-of-origin contexts. We show that the majority of allele-specific methylation occurs due to lineage rather than parent-of-origin factors, regardless of the reproductive state. Interestingly, genes affected by allele-specific DNA methylation often exhibit both lineage and parent-of-origin effects, indicating that they are particularly labile in terms of DNA methylation patterns. Additionally, we re-analyzed our previous study on parent-of-origin-specific expression in honey bees and found little association with parent-of-origin-specific methylation. These results indicate strong genetic background effects on allelic DNA methylation and suggest that although parent-of-origin effects are manifested in both DNA methylation and gene expression, they are not directly associated with each other.

Abstract:
Many autoimmune diseases are more frequent in females than in males in humans and their mouse models, and sex differences in immune responses have been shown. Despite extensive studies of sex hormones, mechanisms underlying these sex differences remain unclear. Here, we focused on sex chromosomes using the “four core genotypes” model in C57BL/6 mice and discovered that the transcriptomes of both autoantigen and anti-CD3/CD28 stimulated CD4+T lymphocytes showed higher expression of a cluster of 5 X genes when derived from XY as compared to XX mice. We next determined if higher expression of an X gene in XY compared to XX could be due to parent-of-origin differences in DNA methylation of the X chromosome. We found a global increase in DNA methylation on the X chromosome of paternal as compared to maternal origin. Since DNA methylation usually suppresses gene expression, this result was consistent with higher expression of X genes in XY cells because XY cells always express from the maternal X chromosome. In addition, gene expression analysis of F1 hybrid mice from CAST × FVB reciprocal crosses showed preferential gene expression from the maternal X compared to paternal X chromosome, revealing that these parent-of-origin effects are not strain-specific. SJL mice also showed a parent-of-origin effect on DNA methylation and X gene expression; however, which X genes were affected differed from those in C57BL/6. Together, this demonstrates how parent-of-origin differences in DNA methylation of the X chromosome can lead to sex differences in gene expression during immune responses.

Abstract:
In previous work from this laboratory, an inverse dependence was established for the adenovirus type 2 E2A late promoter between sequence-specific DNA methylation and promoter activity [1-5; for reviews see ref. 6, 7]. The effect of DNA methylation on promoter activity was also assessed in the transgenic mice, which were obtained from microinjections of unmethylated or in vitro HpaII-premethylated pAd2E2AL-CAT DNA [1] into F2 zygotes from B6D2F, (C57BL/6 × DBA/2) hybrid mice. In CAT assays carried out on organ extracts from the pAd2E2AL-CAT mice, the inverse relationship was confirmed [2].We studied the stability of the pAd2E2AL-CAT DNA methylation patterns in up to eight mouse generations and assessed the influence of the strain-specific genetic background. Three pAd2E2AL-CAT mouse lines were crossed with inbred DBA/2, C57BL/6 or B6D2F, mice. Parent-of-origin effects were controlled by exclusive hemizygous transgene transmission either via females or males. The founder animal of line 7-1 carried two groups of transgenes (A and B) on separate chromosomes. The transgene methylation patterns of the 7-1B transgenes and those of the lines 5-8 and 8-1 were stably transmitted.Southern blot hybridization experiments [8, 9] revealed that the 7-1A transgene methylation pattern was a cellular mosaic. In mixed-genetic-background offspring from 7-1A animals, 10% carried transgenes with HpaII-DNA methylation levels that were reduced from 40 to 10-15%. This finding suggested that in this background the factors that supported high methylation levels were dominant. When inbred DBA/2 mice were the mates, 40% of the siblings carried demethylated transgenes, whereas this ratio amounted to only 10% in C57BL/6 offspring (comparable to B6D2F1 crossings). Transgene methylation patterns were not detectably influenced by the parent-of-origin.

Abstract:
ABSTRACT The 2.4-kb H19 imprinting control region (H19ICR) is required to establish parent-of-origin-specific epigenetic marks and expression patterns at the Igf2/H19 locus. H19ICR activity is regulated by DNA methylation. The ICR is methylated in sperm but not in oocytes, and this paternal chromosome-specific methylation is maintained throughout development. We recently showed that the H19ICR can work as an ICR even when inserted into the normally nonimprinted alpha fetoprotein locus. Paternal but not maternal copies of the ICR become methylated in somatic tissue. However, the ectopic ICR remains unmethylated in sperm. To extend these findings and investigate the mechanisms that lead to methylation of the H19ICR in the male germ line, we characterized novel mouse knock-in lines. Our data confirm that the 2.4-kb element is an autonomously acting ICR whose function is not dependent on germ line methylation. Ectopic ICRs become methylated in the male germ line, but the timing of methylation is influenced by the insertion site and by additional genetic information. Our results support the idea that DNA methylation is not the primary genomic imprint and that the H19ICR insertion is sufficient to transmit parent-of-origin-dependent DNA methylation patterns independent of its methylation status in sperm.

Abstract:
Abstract The phenomenon of chromosome, or genomic, imprinting indicates the relevance of parental origin in determining functional differences between alleles, homologous chromosomes, or haploid sets. In mealybug males (Homoptera, Coccoidea), the haploid set of paternal origin undergoes heterochromatization at midcleavage and remains so in most of the tissues. This different behavior of the two haploid sets, which depends on their parental origin, represents one of the most striking examples of chromosome imprinting. In mammals, DNA methylation has been postulated as a possible molecular mechanism to differentially imprint DNA sequences during spermatogenesis or oogenesis. In the present article we addressed the role of DNA methylation in the imprinting of whole haploid sets as it occurs in Coccids. We investigated the DNA methylation patterns at both the molecular and chromosomal level in the mealybug Planococcus citri. We found that in both males and females the paternally derived haploid set is hypomethylated with respect to the maternally derived one. Therefore, in males, it is the paternally derived hypomethylated haploid set that is heterochromatized. Our data suggest that the two haploid sets are imprinted by parent-of-origin-specific DNA methylation with no correlation with the known gene-silencing properties of this base modification.

Abstract:
Parent-of-origin–dependent gene expression in mammals and flowering plants results from differing chromatin imprints (genomic imprinting) between maternally and paternally inherited alleles. Imprinted gene expression in the endosperm of seeds is associated with localized hypomethylation of maternally but not paternally inherited DNA, with certain small RNAs also displaying parent-of-origin–specific expression. To understand the evolution of imprinting mechanisms in Oryza sativa (rice), we analyzed imprinting divergence among four cultivars that span both japonica and indica subspecies: Nipponbare, Kitaake, 93-11, and IR64. Most imprinted genes are imprinted across cultivars and enriched for functions in chromatin and transcriptional regulation, development, and signaling. However, 4 to 11% of imprinted genes display divergent imprinting. Analyses of DNA methylation and small RNAs revealed that endosperm-specific 24-nt small RNA–producing loci show weak RNA-directed DNA methylation, frequently overlap genes, and are imprinted four times more often than genes. However, imprinting divergence most often correlated with local DNA methylation epimutations (9 of 17 assessable loci), which were largely stable within subspecies. Small insertion/deletion events and transposable element insertions accompanied 4 of the 9 locally epimutated loci and associated with imprinting divergence at another 4 of the remaining 8 loci. Correlating epigenetic and genetic variation occurred at key regulatory regions—the promoter and transcription start site of maternally biased genes, and the promoter and gene body of paternally biased genes. Our results reinforce models for the role of maternal-specific DNA hypomethylation in imprinting of both maternally and paternally biased genes, and highlight the role of transposition and epimutation in rice imprinting evolution.

Abstract:
ABSTRACT Imprinted genes are expressed in a monoallelic, parent-of-origin-specific manner. Clusters of imprinted genes are regulated by imprinting control regions (ICRs) characterized by DNA methylation of one allele. This methylation is critical for imprinting; a reduction in the DNA methyltransferase DNMT1 causes a widespread loss of imprinting. To better understand the role of DNA methylation in the regulation of imprinting, we characterized the effects of Dnmt1 mutations on the expression of a panel of imprinted genes in the embryo and placenta. We found striking differences among imprinted domains. The Igf2 and Peg3 domains showed imprinting perturbations with both null and partial loss-of-function mutations, and both domains had pairs of coordinately regulated genes with opposite responses to loss of DNMT1 function, suggesting these domains employ similar regulatory mechanisms. Genes in the Kcnq1 domain were less sensitive to the absence of DNMT1. Cdkn1c exhibited imprinting perturbations only in null mutants, while Kcnq1 and Ascl2 were largely unaffected by a loss of DNMT1 function. These results emphasize the critical role for DNA methylation in imprinting and reveal the different ways it controls gene expression.

Abstract:
Many imprinted genes are necessary for normal human development. Approximately 70 imprinted genes have been identified in humans. I developed a novel approach to identify candidate imprinted genes in humans using the premise that imprinted genes are often associated with nearby parent-of-origin-specific DNA differentially methylated regions (DMRs). I identified parent-of-origin-specific DMRs using sodium bisulfite-based DNA (CpG) methylation profiling of uniparental tissues, mature cystic ovarian teratoma (MCT) and androgenetic complete hydatidiform mole (AnCHM), and biparental tissues, blood and placenta. In support of this approach, the CpG methylation profiling led to the identification of parent-of-origin-specific differentially methylated CpG sites (DMCpGs) in known parent-of-origin-specific DMRs. I found new DMRs for known imprinted genes NAP1L5 and ZNF597. Most importantly, I discovered many new DMCpGs, which were associated with nearby genes, i.e., candidate imprinted genes. Allelic expression analyses of one candidate imprinted gene, AXL, suggested polymorphic imprinting of AXL in human blood.
