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 3 Relative gene expression levels of TLR2 according to polymorphic genotypes. A: Comparison between TLR2-196 to -174ins/ins (wild-type) and ins/del + del/del (polymorphic) in gastric cancer (GC), P = 0.0010 and chronic gastritis (CG), P = 0.5334 groups. B: TLR2-19216 TT (wild type) and TC + CC (polymorphic) in GC, P = 0.0004 and CG, P = 0.8827 groups. Significant difference, ^aP < 0.05. Relative quantification (RQ) represented by median with interquartile range. Mann-Whitney U statistical test.
