CDH1 and nasopharyngeal carcinoma: miR-144 is inversely correlated with the expression of tumor suppressor gene phosphatase and tensin homolog (PTEN) in the NPC specimens and cell lines; consequently, miR-144 suppresses the expression of PTEN to increase the expression of phosphorylated protein kinase B (pAkt) and cyclin D1, and promote G(1)-phase transition and then decreases the expression of E-cadherin to promote migration and invasion [78].
