            "literature_evidence": "The present study investigated GNK1 expression in different mucosa biopsy specimens from gastric cancer, cancer-adjacent lesions, atrophic gastritis and normal control subjects (superficial gastritis patients). We found that GKN1 mRNA expression was progressively downregulated from corresponding distant non-tumour tissues to tumour tissues, and was lower than in the control tissues of both groups. This suggested that low or absent expression of GKN1 may contribute to gastric carcinogenesis. This is consistent with a previous study that demonstrated decreased GKN1 expression in gastric cancer tissues. In addition, we analysed GKN1 expression in two types of gastric cancer and found that the mRNA level of GKN1 was lower in patients with diffuse type gastric cancer. This indicates that GKN1 may be related to tumour classification. [PMID:25469040]",
