Characterization and strong risk association of TLR2 del -196 to -174 polymorphism and Helicobacter pylori and their influence on mRNA expression in gastric cancer

Figure 1 Relative gene expression levels of TLR2. A: Comparison between gastric cancer (GC) and chronic gastritis groups (CG), ^aP < 0.0001; and GC or CG groups with samples of normal mucosa (RQ = 1 represented for dashed line), ^bP < 0.0001 and P = 0.9387, respectively. B: Individual representation of RQ for each sample of GC group; C: Individual representation of relative quantification (RQ) for each sample of CG group. Significant difference, ^{a, b}P < 0.05. RQ represented by median with interquartile range. Mann-Whitney and Wilcoxon Signed statistical test.
