For instance, Wang et al. [33] revealed that Wnt/β-catenin signaling (including β-catenin, cyclin D1, c-Myc, and MMP-7) and p-eIF4E expression were elevated in NPC compared with noncancerous nasopharyngeal epithelial tissues and associated with clinical characteristics of NPC patients. This evidence concerns the gene MMP7 and nasopharyngeal carcinoma.
