The study objective was to determine if maternal administration of sulforaphane (SFN) induced Nrf2-controlled genes. In acute studies, when non-pregnant and pregnant mice were orally exposed to SFN (50 or 100 mg/kg) on gestational day (GD) 14 and euthanized after 2, 6 or 24 h, results demonstrated increased GSTM1, NQO1, HO-1, and Gclc mRNA transcript levels in adult liver, but no change in NQO1 activity. In sub-chronic studies, when non-pregnant and pregnant mice were orally exposed to SFN (65 mg/kg) daily for 30 days and euthanized on GD14, results demonstrated a 2- to 3-fold increase in GSTM1, Gclc and NQO1 transcript levels, and a 2-fold increase in NQO1 activity in adult livers. No effects of maternal treatment on fetal liver gene transcript levels or enzyme activity were observed. Demonstration that SFN induces maternal gene expression and activity supports further investigation of SFN as a preventative agent against transplacental toxicity. (C) 2013 Elsevier Inc.
