H pylori up-regulates MMP-1 in a protein kinase C (PKC)-dependent manner. BIS I-treated or non-treated AGS cells were incubated with H pylori P12 wt, PMA (A–D) or H pylori P1 wt or the cagA and virB7 mutants (E, F) for 3 h or for the indicated periods of time. MMP-1 expression was analysed by qRT-PCR (A, C, E) or immunoblotting (B, D, F). The graphs in (B) summarise the densitometric analysis of three independent immunoblots (experiments). GAPDH, occludin and histone H3 were immunodetected to show the appropriate fractionation and equal protein amounts in the cell samples. Bacterial lysate was used as a negative control. *p<0.05, **p<0.01 versus non-stimulated cells; #p<0.05, ##p<0.01 versus BIS I-free stimulated cells.
