Effects of epigenetic modulatory drugs on fetal alcohol induced changes in pituitary D2R mRNA levels, protein levels, pituitary weight and plasma PRL levels.

AD, PF and AF rat offspring were treated with DNA methyl transferase inhibitor 5-Aza deoxycytidine (5-AZAdC), HDACC inhibitor Trichostatin-A (TSA) alone or together during postnatal day 2–6 and after 60 days, these rats were ovariectomized and estrogen treated for 60 days. Mean ± SEM values of pituitary D2R mRNA levels (A), pituitary weight (B) and plasma PRL levels (C) are shown in the histograms. Data are mean ± SEM of n = 6 animals per group and were analyzed using one-way ANOVA with the Newman-Keuls post hoc test. *, P<0.05, between AF and controls (AD or PF). @, P<0.05 between the treatment and control in AF group.
