Abstract:
Objective To observe the effect of Bufalin on controlling ECA109 cells , and to explore its potential anti-tumor mechanism. Method The effect of Bufalin on the proliferation of human esophageal cancer ECA109 cells was evaluated by CCK-8 assay and it effects on apoptosis of esophageal cancer ECA109 cells were determined by flow cytometry (FCM). Protein expressions of NF-κBp65, ERK, PERK1/2 and Caspase-3, Cleaved Caspase-3, PARP, Cleaved PARP in esophageal cancer ECA109 cell were observed through Western blot. Results The proliferation of human esophageal cancer ECA109 cells was significantly inhibited in bufalin group in a time- and concentration-dependent manner. Bufalin can induce the apoptosis in human esophageal ECA109 cells. Results of Western blot showed the protein expressions of apoptosis-related protein Cleaved Caspas-3 and Cleaved PARP in esophageal cancer ECA109 cells could be markedly up-regulated by Bufalin , but p-ERK1/2, NF-κBp65 in esophageal cancer ECA109 cells could be markedly down-regulated by Bufalin. Conclusion Bufalin can potently inhibit the growth of esophageal cancer ECA109 cells and the potential anti-tumor mechanism might be involved in inhibiting ERK/ NF-κB signal pathway.
