"Data suggest that maternal glycemic response during pregnancy is associated with lower DNA methylation of 4 CpG sites within PDE4B gene in placenta (collected after term birth); 3 additional CpG sites are differentially methylated relative to maternal glucose response within TNFRSF1B LDLR and BLM genes. (TNFRSF1B = TNF receptor superfamily member-1B; LDLR = low density lipoprotein receptor; BLM = Bloom syndrome protein)"xsd:string
