Our results showed that when infected by 26695, H879 or MALT1, for the GES-1 cells and the BGC823 cells, the number of significant DEGs in the BGC823 cells stimulated by the three isolates were much more than that of the GES-1 cells (Table 1), suggesting that BGC823 cell line is much more sensitive to the infection of H. pylori than GES-1 cell line. Here, MALT1 is linked to infection.
