The common differentially expressed genes between T2DM and H. pylori infection. (A) Volcano plot of DEGs in the T2DM-related GSE26168 dataset. (B) Volcano plot of DEGs in the H. pylori infection-related GSE27411 dataset. Red dots represent up-regulated DEGs, blue dots represent down-regulated DEGs, and gray dots represent genes that were not significantly different between the two groups. (C) Common DEGs in the GSE26168 dataset (blue) and GSE27411 dataset (red) were represented by venn diagrams. Abbreviations: T2DM: type 2 diabetes mellitus; Hp: Helicobacter pylori
