In addition, since β-catenin was shown to be the important regulator of cell death and peritoneal metastasis of GC cells and its transcription was regulated by many factors (such as MALAT1, CDYL, Hsp70 and p14ARF) 39-41 , it should be confirmed in future work whether GC cells have a molecular interaction network that influences the actions of β-catenin 41. This evidence concerns the gene CDKN2A and gastric cancer.
