The effect of genotype and in utero environment on inter-individual variation in neonate DNA methylomes (methylomes)

ABSTRACT: We surveyed the genotypes and DNA methylomes of 237 neonates and found 1423 punctate regions of the methylome that were highly variable across individuals, termed variably methylated regions (VMRs), against a backdrop of homogeneity. Although methQTLs were readily detected in neonatal methylomes, genotype alone did not explain the majority of the VMRs. We found that the best explanation for 75% of VMRs was the interaction of genotype with different in utero environments, including maternal smoking, maternal depression, maternal BMI, infant birth weight, gestational age and birth order.

Programming and inheritance of parental DNA methylomes in mammals

Programming and inheritance of parental DNA methylomes in mammals

Project description:The reprogramming of parental methylomes is essential for embryonic development. In mammals, paternal 5-methylcytosines (5mCs) have been proposed to be actively converted to oxidized bases. These paternal oxidized bases and maternal 5mCs are believed to be passively diluted by cell divisions. By generating single-base resolution, allele-specific DNA methylomes from mouse gametes, early embryos, and primordial germ cell (PGC), as well as single-base-resolution maps of oxidized cytosine bases for early embryos, we report the existence of 5hmC and 5fC in both maternal and paternal genomes and find that 5mC or its oxidized derivatives, at the majority of demethylated CpGs, are converted to unmodified cytosines independent of passive dilution from gametes to four-cell embryos. Therefore, we conclude that paternal methylome and at least a significant proportion of maternal methylome go through active demethylation during embryonic development. Additionally, all the known imprinting control regions (ICRs) were classified into germ-line or somatic ICRs. The cross of two mouse strains was performed using DBA/2J as the paternal strain and C57BL/6J as the maternal strain. The hybrid embryos were collected at 2-cell, 4-cell, ICM, E6.5, E7.5 stages. Female and male E13.5 PGC samples (B6; 129S4-Pou5f1tm2Jae/J) were collected from timed mating of C57BL/6J female mice. MethylC-Seq: oocytes (C57BL/6J), sperm (DBA/2J), 2-cell embryos, 4-cell embryos, ICM, E6.5 embryos, E7.5 embryos, E13.5 female PGCs and E13.5 male PGCs. TAB-Seq: 2-cell embryos. fCAB-Seq: 2-cell embryos. RNA-Seq: oocytes (C57BL/6J).
