This article addresses that overexpression of phospo-GSK3β (ser9) is positively correlated with prognosis of gastric cancer (36); phospo-GSK3β (ser9) is induced by gastrin and leads to GSK3β inhibition, increased Snail expression, nuclear translocation of β-catenin, and an increase in cell migration in gastric cancer (37). This evidence concerns the gene GAST and gastric cancer.
