Background and Aim: Adenosine A1 receptor (AA1R) has been shown to have an inhibitory effect on cell growth in several cancers; however, its function in esophageal cancer is still unclear. In this study, we examined the effect of AA1R on cell growth and apoptosis in esophageal cancer cells. Materials and methods: In this study, YM-1 and KYSE-30 esophageal cancer cell lines were cultured. AA1R gene expression was determined by quantitative Real-time Polymerase Chain Reaction (qRT-PCR). As well, the AA1R antagonist (DPCPX) effect on cell viability was evaluated by the MTT assay. Moreover, apoptosis was assessed by annexin-V and propidium iodide staining, and the caspase-3/7 activity assay kit. Result: qRT-PCR results indicated that the AA1R was expressed in YM-1 and KYSE30 cells. In addition, DPCPX significantly decreased cell proliferation in both cell lines. Furthermore, the A1AR antagonist induced apoptosis in KYSE-30 and YM-1 cells. After treatment of both cell lines with DPCPX, the caspase 3/7 activity was increased. Conclusion: Our finding indicates the AA1R antagonist induces apoptosis through caspase 3/7 activation and can be considered a potential target in esophageal cancer therapy.
