Maternal Obesity Is Associated With A Sex-Specific Epigenetic Programming In Human Neonatal Monocytes
EPIGENOMICS(2020)
摘要
Aim: To determine changes in global DNA methylation in monocytes from neonates of women with obesity, as markers of an immune programming resulting from maternal obesity. Materials & methods: Cord blood monocytes were obtained from neonates born to women with obesity and normal weight, genome-wide differentially methylated CpGs were determined using an Infinium MethylationEPIC-BeadChip (850K). Results: No clustering of samples according to maternal BMI was observed, but sex-specific analysis revealed 71,728 differentially methylated CpGs in female neonates from women with obesity (p < 0.01). DAVID analysis showed increased methylation levels within genes involved in the innate immune response and inflammation. Conclusion: Maternal obesity induces, in a sex-specific manner, an epigenetic programming of monocytes that could contribute to disease later in life.
