Purpose: To investigate the effect of apigenin on Barrett's esophagus-associated esophageal adenocarcinoma (BEAC) cells OE33, and also to ascertain the mechanism by which it inhibits cellular proliferation and motility. Methods: Proliferation index of OE33 in the absence and presence of apigenin was determined by methyl-thiazolyl-tetrazolium (MTT) assay and apoptosis was determined by enzyme-linked immunosorbent assay (ELISA) method. Boyden Chamber's assay was applied to determine the migration

Results: Apigenin resulted in the inhibition of the proliferation of OE33 cells in a dose-and timedependent fashion, with an IC50 of 75 µM, after 72 h of incubation, and also induced apoptosis, with modulation of pro-and anti-apoptotic genes. Furthermore, apigenin inhibited the motility of OE33 by targeting PI3K/Akt/mTOR signaling. Conclusion: Apigenin effectively inhibits the oncogenicity of OE33 cells by targeting PI3K/Akt/mTOR pathway.
