Celecoxib inhibits Helicobacter pylori colonization-related factors

AIM:To investigate the effect of celecoxib,a selective COX-2 inhibitor,on Helicobacter pylori(H.pylori) colonization-related factors and its mechanism.METHODS:After co-incubation with celecoxib,morphology of H.pylori strain 26695 was observed under a transmission electron microscope.Flagella motility was assessed by stab agar motility test.Adherence of H.pylori to AGS cells was determined by enzyme linked immunosorbent assay.Levels of mRNA expression in flagellar genes(flaA,flaB),urease genes(ureA,ureB)and ...
