Increment of H33342 (20 µM) accumulated in Caco-2 cells after adding a 1 or 5 mM NaF with 10 µM Ko143, b 1–100 µM Ko143 with 5 mM NaF, c 400 ng/mL AFB₁ with or without 10 µM Ko143 and 5 mM NaF, d 100, 400 and 1000 ng/mL AFB₁, e 10 µM Ko143 with 5 mM NaF, 1 mg/mL green tea infusion, 50 µM quercetin and each catechins (n = 4–6). Data is presented as mean ± SD compared to control at zero percent increment (*p < 0.05, **p < 0.01, ***p < 0.001)
