Alterations of tumor-associated phenotypes by overexpression of AGR2 in SNU-869 cells. A. AGR2 expression in the SNU-869 stable transfectants was verified by real-time RT-PCR. The AGR2 transcript level was normalized against that of GAPDH. Results shown are means ± standard deviations of (1/2)CT of target - CT of GAPDH of three experiments. B. AGR2 protein expression in the SNU-869 stable transfectants was detected by western blot analysis with β-actin as a loading control. The result shown is a representative of three experiments. C. Viability of the SNU-869 stable transfectants was measured by the MTT assay. Results shown are means ± standard deviations of three experiments (ANOVA P = 0.008; post hoc analysis by Bonferroni testing: AGR2-2 vs. AGR2-N, P = 0.013). D. The effect of AGR2 overexpression on cell proliferation. Pulsed BrdU incorporation into the SNU-869 stable transfectants was measured by flow cytometry. Percentage of BrdU-positive cells was shown in mean ± standard deviation of four experiments (ANOVA P = 0.053; post hoc analysis by Bonferroni testing: AGR2-2 vs. AGR2-N, P = 0.027). Results shown are representatives of four experiments. E. The effect of AGR2 overexpression on tumor cell invasion of SNU-869 cells. The numbers of invading cells in the transwell invasion assay were determined for SNU-869 stable transfectants. Results shown are means ± standard deviations of three experiments (ANOVA P = 0.003; post hoc analysis by Bonferroni testing: AGR2-2 vs. AGR2-N, P = 0.026).
