DON exposure decreased Nrf2 transcriptional activity. IPEC-J2 cells were treated with different concentrations of DON (0–2 μM) for 24 h. The mRNA expression of NRF2 (A) and NQO-1 (B) was determined by real-time PCR. The expression levels of mRNA are expressed relative to the values in the control. Different superscript lowercase letters within each group indicate significant difference (p < 0.05). n = 3.
