The effect of combinations of Quercetin and 5-fluorouracil on growth inhibition of MDA-MB-231

(A) Viability of MDA-MB-231 cells after treatment with Quercetin (50 and 200μM) combined with 5-fluorouracil (1.5, 6.25, and 25μM) for 24 hr was measured using MTT assay. (B) Viability of MDA-MB-231 cells after treatment with Quercetin (50 or 200μM) combined with 5-fluorouracil (1.5, 6.25, or 25μM) for 48 hr was measured using MTT assay. Results are presented as mean± SEM of at least three independent experiments *P<0.05; **P<0.01; ***P<0.001 significant from control untreated cells, and ##P<0.01 significant from 5-FU-alone treated cells
