Expression of lipocalin-2 (Lcn2) determined by qRT-PCR. Expression is relative to the 18S ribosomal RNA in arbitrary units. Data are mean ± SEM. Columns sharing a superscript letter are not significantly different (P > 0.05). a Expression in fetal liver of female fetuses on d21 of gestation 18S n = 8, 9S n = 10, 18C n = 8, 9C n = 7. Data were analyzed by REML Protein P = 0.007 Oil P = 0.008 Protein·Oil P = 0.273. b Expression in fetal liver of male fetuses on d21 of gestation (n = 6 for all groups). c Expression in liver of female offspring at 6 weeks of age (n = 6 for all groups). Data were analyzed by two-way ANOVA Protein P = 0.167, Oil P = 0.035, Protein·Oil P = 0.94
