GKN1 and gastric cancer: When we compared telomere length in 35 gastric cancer tissues with that of corresponding non-neoplastic gastric mucosae, we found that telomeres were significantly shorter in gastric cancers (Figure 6D) (P = 0.0014), and an inverse correlation was detected between telomere length and GKN1 protein expression (Figure 6E, P < 0.0001).
