Abstract:
Objective: To investigate the effect of ELMOD2 over-expression on the malignant biological behaviors of gastric cancer MGC803 cells, and to study its related molecular mechanism. Methods: GV141-ELMOD2 expression vector was transfected into human gastric cancer MGC803 cells. The mRNA and protein expressions of ELMOD2 were detected by Real-time fluorescent quantitative PCR and WB, respectively. The cell proliferation ability was detected by CCK-8 method. Apoptosis rate was detected by flow cytometry. The cell migration ability was detected by Transwell method. The protein expressions of PCNA, BAX and Bcl-2 and Vimentin were detected by WB. Results:After transfection of ELMOD2 expression vector, the mRNAand protein expressions of ELMOD2 were significantly increased in MGC803 cells (P<0.05). Further studies showed that over-expression of ELMOD2 increased the proliferation and migration ability but reduced the apoptosis rate of MGC803 cells significantly (P<0.05 or P<0.01). The protein levels of PCNA, Vimentin and Bcl-2 in MGC803 cells increased, while the protein level of BAX decreased (P<0.05 or P<0.01). Conclusion: Over-expression of ELMOD2 can promote the proliferation and migration of MGC803 cells and inhibit cell apoptosis. These effects may be achieved by increasing the protein level of PCNA, Vimentin and Bcl-2, and reducing the protein level of BAX.
