Fig. 1. Western blots of MMP-7 and ß-actin in gastric biopsies from control and H. pylori- infected subjects. Top panels, representative blots of MMP-7 and ß-actin from control subjects (-) and subjects infected with H. pylori (+) in biopsies from the gastric corpus (A) and antrum (B). Bottom panels, the relative abundance in corpus (C) and antrum (D) of MMP-7 and ß-actin. (C) Plasma gastrin concentrations are indicated in panel C, where MMP-7 and ß-actin data are also shown for the subset of H. pylori-positive patients in which plasma gastrin concentrations were in the normal range (i.e. <30 pM). Data for corpus based on n=11 control subjects (open bars) and 16 H. pylori-positive subjects; data for antrum based on n=10 control subjects and n=6 H. pylori-positive subjects. Means±s.e.m. *P<0.05.
