From: How do maternal emotion and sleep conditions affect infant sleep: a prospective cohort study
Comparison of DNA methylation levels of placental DR, GR, MR, and EPAC genes between pregnant women in Group 3 and Group 4. Group 3: Postpartum sleep disorder; Group 4: No sleep disorder. The paired t-test was used for statistical analysis (*P < 0.05, **P < 0.01, ***P < 0.001). EPAC: exchange proteins directly activated by cAMP receptor; GR: glucocorticoid receptor; DR: dopamine receptor; MR: melatonin receptor. NR3C1 and NR3C2 are the genes of GR; MTNR1A and MTNR1B are the genes of MR; DRD1 and DRD2 are the genes of DR; RAGRF 1 and RAGRF 2 are the genes of EPAC
