Maternal administration of high-dose AA to SMP30/GNL KO dams during the lactation period. (a) Experimental protocol of the maternal administration of high-dose AA to SMP30/GNL KO dams during the lactation period. Upon delivery (d2), KO dams were divided into the KO and KOA groups. The KO group had free access to 1.5 g/L AA water, whereas the KOA group was given 3.0 g/L AA water orally and injected intraperitoneally (i.p.) with 4.0 g/L AA. Upon birth, during the lactation period, male offspring were divided into the two groups as above. Plasma AA levels in dams on d2 (n = 6 per group). (c) Body weights of KO and KOA offspring from birth to d16 (left panel, statistical analysis using a one-way ANOVA with Tukey’s multiple comparison test) and liver weight on d16 (right panel) (n = 6 per group). (d) Plasma and hepatic AA levels in KO and KOA offspring on d16 (n = 6–8 per group). (e) 5hmC levels in the livers of KO and KOA offspring on d16 (n = 6 per group). Statistical analysis using an unpaired Student’s t-test unless otherwise indicated. Data are expressed as the mean ± SEM. *p < 0.05; ** p < 0.01; N.S., not significant vs. KOA offspring.
