Abstract:
Objective To investigate the effect of IFN-γ on the proliferation and migration of esophageal squamous cell carcinoma cell line Eca9706 and related mechanism. Methods Cells were cultured in vitro and treated with interferon-γ. Cell morphology changes were observed under microscope, cell proliferation ability was detected by CCK-8 experiment, and cell migration ability was detected by cell scratch experiment and Transwell experiment. Real-time PCR method was used to detect the expression efficiency of chemokine CXCL8 (interleukin 8), and the ELISA experiment was used to detect the change of CXCL8 secretion. Results Compared with the blank control group, Eca9706 cells treated with different concentrations of interferon-γ did not change significantly in cell morphology. CCK8 experiment confirmed that the proliferation ability of Eca9706 cells after IFN-γ treatment was significantly reduced (P < 0.01). Cell scratch experiment found that IFN-γ significantly decreased the migration ability of Eca9706 cells (P < 0.01). Transwell experiment showed that after IFN-γ treatment, the migration ability of Eca9706 cells was significantly inhibited (P < 0.01). CXCL8 gene expression level in Eca9706 cells treated with interferon-γ was significantly down-regulated (P < 0.01), and the amount of CXCL8 secretion significantly reduced (P < 0.05). Conclusion Interferon-γ can inhibit the proliferation and migration of esophageal cancer cell line Eca9706, which may be related to its inhibition of the expression and secretion of CXCL8.
