MAPK8 and gastric cancer: MiR‐381 may also regulate the Wnt/β‐catenin pathway by downregulating zinc finger E‐box binding homeobox 1 (ZEB1); this suppresses the phosphorylation of c‐Jun N‐terminal kinase (JNK) and c‐Jun and decreases the expression of Wnt3a, Wnt5a and β‐catenin in gastric cancer cells.
