Fig. 3From: PPARGC1α gene DNA methylation variations in human placenta mediate the link between maternal hyperglycemia and leptin levels in newbornsMediation analyses between maternal glucose levels, DNA methylation variations, and cord blood leptin concentrations. Squared numbers correspond to the coefficients for the total effect with associated p values. Path a is the relationship between maternal variables and DNA methylation levels. Path b is the relationship between DNA methylation levels and cord blood leptin levels. Path c is the indirect relationship between maternal variables and cord blood leptin levels, and c‘ is the direct effect of this relationship when taking into account the DNA methylation signature. a DNA methylation variations at the PPARGC1α - CpG3 gene locus induced by glycemia at the second trimester of pregnancy mediate cord blood leptin levels. b DNA methylation variations at the PPARGC1α - CpG4 gene locus induced by glycemia at the second trimester of pregnancy mediate cord blood leptin levels. c The mediation effect of DNA methylation variations at the PRDM16 - CpG2 gene locus was demonstrated between maternal glycemia at the third trimester of pregnancy and cord blood leptin levelsBack to article page
