The expressions of miR-506 and mRNA levels of E-cadherin were found to be decreased in NPC tissues in comparison to those in paracancerous tissues, but the mRNA levels of LHX2, Wnt1, β-catenin, Vimentin, and Twist were elevated (all p < 0.05) (Fig. 2a). The gene discussed is TWIST1; the disease is nasopharyngeal carcinoma.
