Antioxidants (VC and Res) significantly reverse E2-mediated decrease in Nrf2 mRNA and protein expression levels in MCF-10A cells. (A) Nrf2 mRNA expression levels in MCF-10A cells treated with 50 nM E2, 50 μM Res, Res + E2, 1 mM VC or VC + E2 for 24 hr and (B) Nrf2 protein expression levels in MCF-10A cells treated with 50 nM E2, 50 μM Res, Res + E2, 1 mM VC or VC + E2 for up to 48 hr.
‘*’ indicates p value ≤ 0.05 compared with respective controls.
