BARX2 and gastric cancer: Consistent with our qRT-PCR and WB results, positive Barx2 protein staining was more visible in normal gastric mucosa than in primary GC specimens (92.0% vs. 37.5%, P=0.002) and corresponding LNM tissue (92% vs. 15.4%, P=0.020) according to IHC staining in a TMA, suggesting that Barx2 takes part in the tumorigenesis and progression of GC.
