Abstract Background Gestational diabetes mellitus (GDM) is a common pregnancy-specific disease and growing at an alarming rate worldwide, which can negatively affect the health of pregnant women fetuses. However, most studies are limited to one tissue, placenta or umbilical cord blood, usually with omics assay. It thus difficult systematically reveal molecular mechanism GDM key influencing factors on offspring. Results We recruited group 21 20 controls without GDM. For each woman, reduced representation bisulfite sequencing RNA-seq were performed using paired neonatal blood specimens. Differentially methylated regions (DMRs) differentially expressed genes (DEGs) identified body mass index as covariate. Through comparison control samples, 2779 141 DMRs, 1442 488 DEGs from respectively. Functional enrichment analysis showed that methylation expression profiles mirrored characteristics “type II diabetes” “insulin resistance.” Methylation-altered in associated pathways “cholesterol metabolism.” Remarkably, both DMRs illustrated significant overlaps among samples. The overlapping top-ranking enriched shared include “growth hormone synthesis, secretion action” mellitus.” Conclusions Our research demonstrated epigenetic transcriptomic alternations findings emphasized importance modifications communication between offspring, provided reference for prevention, control, treatment, intervention perinatal deleterious events complications.
