Fig. 2From: Protein signature characterizing Helicobacter pylori strains of patients with autoimmune atrophic gastritis, duodenal ulcer and gastric cancerPrincipal component analysis of proteome maps of Helicobacter pylori isolates related to autoimmune atrophic gastritis (AAG), duodenal ulcer (DU) and gastric cancer (GC). The loading plots show an overview of the H. pylori spot maps of GC versus DU (a) and GC versus AAG (b). Each circle represents a spot map. AAG, DU and GC associated H. pylori spot maps are displayed in grey, white and black, respectivelyBack to article page
