Objective Transcription of human endogenous retrovirus (HERV) elements is usually suppressed by epigenetic factors such as DNA methylation and heterochromatin silencing by histone modifications. There is an association between maternal smoking during pregnancy and DNA methylation levels in placental tissue and in DNA from cord blood. Study Design We assessed the transcriptional activity of HERV-H, HERV-K, and HERV-W in umbilical cord blood from 47 term babies unexposed to tobacco smoke in utero and 23 term babies exposed to tobacco smoke in utero. Results In our population, the HERV-H, HERV-K, and HERV-W families were always transcriptionally active, and the levels of all HERVs (H, K, W) were significantly higher in unexposed than smoke-exposed babies. Conclusion This study provides preliminary information about the transcriptional activity of HERV-H, HERV-K, and HERV-W families in human umbilical cord blood.

Distinct DNA methylation patterns have recently been observed to precede type 1 diabetes in whole blood collected from young children. Our aim was to determine, whether perinatal DNA methylation could be associated with later progression to type 1 diabetes. Reduced representation bisulfite sequencing (RRBS) analysis was performed on umbilical cord blood samples collected within the Type 1 Diabetes Prediction and Prevention (DIPP) study. Children later diagnosed with type 1 diabetes and/or testing positive for multiple islet autoantibodies (N=43) were compared to control individuals (N=79), who remained autoantibody-negative throughout the DIPP follow-up until 15 years of age. Potential confounding factors related to the pregnancy and the mother were included in the analysis. No differences in the cord blood methylation patterns were observed between these cases and controls.
