The incidence of esophageal cancer (EC), especially adenocarcinoma, has increased tremendously in Western countries and the prognosis of EC remains poor. Paeonol (Pae), a phenolic component from the root bark of Paeonia moutan, possesses antitumor effects in vitro and in vivo. The present study showed that Pae had an antiproliferative effect on the two human EC cell lines (SEG-1 and Eca-109), with different sensitivities to Pae. Acridine orange staining and flow cytometry assays showed that Pae induced apoptosis on the two cell lines. Further analyses indicated that Pae resulted in a cell cycle arrest at S-phase. Immunohistochemical staining showed the expression of Bcl-2 was decreased and that of Bax was increased in treatment groups, with the ratio of Bcl-2/Bax decreased correspondingly. The results show that Pae shows growth inhibitory and apoptosis induction property and may be a promising agent for the EC treatment.
