Helicobacter pylori upregulates prion protein expression in gastric mucosa: A possible link to prion disease

Figure 1 A: Representative RT-PCR and densitometric analysis showing PrPc mRNA expression in the gastric mucosa colonized with H pylori before and after successful eradication therapy (n = 10). Data are expressed as means±SE. ^aP<0.05 vs the control group, ^cP<0.05 vs the expression before eradication therapy; B: Representative immunoblot analysis showing PrPc protein expression in the gastric mucosa colonized with H pylori before and after successful eradication therapy.
