We found an increased expression of Snail1 and ZEB1 after stimulation with IL-1β or infection (Figures 3(b) and 3(c)), but Snail1 expression was significantly larger for the H. pylori with the East Asian EPIYA (ABD) than with the Western ABCCC strain, while CDH1 expression was severely diminished by IL-1β treatment or infection with any of the cagA positive H. pylori strains (Figure 3(b)). The gene discussed is S100A8; the disease is infection.
