Abstract:

Objective To investigate the effects of nimesulide(a non-selective cyclooxygenase-2 inhibitor) on cell proliferation inhibition and apoptosis in esophageal squamous cell carcinoma(ESCC) cell line.Methods EC109 cells were incubated with nimesulide.Cell proliferation was assessed by MTT assay.Cell apoptosis induction were determined by fluorescence staining flow cytometry.PGE2 production was measured by ELISA assay to determine the effect of nimesulide on cyclooxygenase activity.Results Nimesulide inhibited cell growth in a concentration and time dependent manner.Apoptosis was induced by Nimesulide dose dependently.This was accompanied with a decrease of PGE2 production.Conclusion Nimesulide could inhibit ESCC cell proliferation and induce apoptosis,which is probably through cyclooxygenase-2 inhibition.Cyclooxygenase-2 inhibitor may be a promising therapeutic agent for human ESCC.

Key words: esophageal squamous cell carcinoma, cyclooxygenase-2, growth inhibition, apoptosis
