Maternal blood lead concentrations, DNA methylation of MEG3 DMR regulating the DLK1/MEG3 imprinted domain and early growth in a multiethnic cohort

Prenatal exposure to lead (Pb) is known to decrease fetal growth; but its effects on postnatal growth and mechanistic insights linking Pb to growth are not clearly defined. Genomically imprinted genes are powerful regulators of growth and energy utilization, and may be particularly vulnerable to environmental Pb exposure. Because imprinting is established early and maintained via DNA methylatio...

Seafood consumption and umbilical cord blood mercury concentrations in a multiethnic maternal and child health cohort

BACKGROUND Fish consumption is common among the cultures of Hawaii, and given public health attention to mercury exposure in pregnancy, it is important to better understand patterns of fish consumption and mercury in pregnancy. This study examined the influence of maternal fish consumption during pregnancy on umbilical cord mercury (Hg) concentrations in a multiethnic cohort of women in Hawaii....

Methylation dynamics of IG-DMR and Gtl2-DMR during murine embryonic and placental development.

The Dlk1-Dio3 imprinted domain on mouse chromosome 12 contains IG-DMR and Gtl2-DMR, whose methylation patterns are established in the germline and after fertilization, respectively. In this study, we determine that acquisition of DNA methylation at the paternal allele of the Gtl2-DMR is initiated after the blastocyst stage and completed by embryonic day 6.5, and that Gtl2 (approved symbol: Meg3...

Depression in pregnancy, infant birth weight and DNA methylation of imprint regulatory elements

Depressed mood in pregnancy has been linked to low birth weight (LBW, < 2,500 g), a risk factor for adult-onset chronic diseases in offspring. We examined maternal depressed mood in relation to birth weight and evaluated the role of DNA methylation at regulatory sequences of imprinted genes in this association. We measured depressed mood among 922 pregnant women using the CES-D scale and obtain...

Lead Exposure during Early Human Development and DNA Methylation of Imprinted Gene Regulatory Elements in Adulthood

BACKGROUND Lead exposure during early development causes neurodevelopmental disorders by unknown mechanisms. Epidemiologic studies have focused recently on determining associations between lead exposure and global DNA methylation; however, such approaches preclude the identification of loci that may alter human disease risk. OBJECTIVES The objective of this study was to determine whether mate...
