Transwell migration assays demonstrated that MGC803 and SGC7901 cells exhibited enhanced migratory capabilities after infection with a Brachyury-overexpressing virus, compared to those infected with a control virus (P < 0.05 and P < 0.01), while, although BGC823 cells also showed enhanced migration, the difference was not statistically significant (P = 0.176) (Fig. 3a). This evidence concerns the gene TBX1 and infection.
