In addition, molecules, including uroplakin 1A (UPK1A) [64] and RBMS3 [65], have been proposed to possess the ability to induce cell cycle arrest at G1/S phase and inhibit tumor invasion and metastasis, which may be mediated by the downregulation of MMP7 in esophageal squamous cell carcinoma or nasopharyngeal carcinoma. Here, MMP7 is linked to nasopharyngeal carcinoma.
