Expression of P-gp in gastric tissues by western blot analysis. A representative autoradiograph performed on tissue lysates of Hp-negative subjects, Hp-positive patients, GC patients and human fetuses. GAPDH expression was used as internal control. The histogram at bottom reports the mean densitometric values of P-gp/GAPDH ratio obtained from three independent experiments. *One-way ANOVA: P<0.0001.
