Background/Aim: The present study investigated the effect of eicosapentaenoic acid (EPA) on nuclear factor-kappa B (NF-κB) activation, inflammatory interleukin-6 (IL-6) production, and cell proliferation in a human oesophageal carcinoma cell line (TE-1). Materials and Methods: Lipopolysaccharide (LPS)-induced IL-6 production in TE-1 cells in the presence or absence of EPA was determined using enzyme-linked immunosorbent assay (ELISA). The proliferation of TE-1 cells was determined by the WST-1 assay. TE-1 cells were stained with Hoechst 33342 and propidium iodide to observe apoptosis. Immunohistochemical staining of NF-κB in TE-1 cells was performed. Results: LPS increased IL-6 production in TE-1 cells, and EPA treatment prevented this effect. EPA treatment inhibited NF-κB activation and induced apoptosis of TE-1 cells. Conclusion: EPA inhibits NF-κB activation and IL-6 production in oesophageal cancer cells, their inducing apoptosis. These effects of EPA may be of benefit in improving the outcome of cancer surgery.
