mRNA expression in Caco-2 cells of heme oxygenase-1 (HO-1) (A and B), nuclear factor (erythroid-derived 2)-like 2 (Nrf2) (C and D), and NAD(P)H quinone reductase (NQO1) (E and F) after treatment with flower extracts of Artocarpus heterophyllus Lam. (left) and Artocarpus lakoocha Roxb. (right), 0–20 µg/mL. Data are expressed as fold changes of the target gene (Nrf2 in A, HO-1 in B, and NQO1 in C) normalized to the internal standard control gene (β-actin). All measurements were performed in triplicate. Data are shown as the mean ± standard deviation, and one-way ANOVA with a Newman–Keuls post-test was used for statistical significance; ** p < 0.005; *** p < 0.0001 vs. 0 µg/mL.
