TIPE1 and gastric cancer: We found that TIPE1 was inversely correlated with differentiation status and distant metastasis in primary gastric cancer tissues and further demonstrated that TIPE1 functions as a metastasis suppressor in gastric cancer by suppressing Wnt/β‐catenin signalling and MMP activity, suggesting that TIPE1 may be a new prognostic indicator and therapeutic target of gastric cancer.
