Osteopontin Promotes EZH2 Expression and Tumor Progression in Nasopharyngeal Carcinoma
Objective: To evaluate the possible mechanism of osteopontin (OPN) in the tumor progression of nasopharyngeal carcinoma (NPC). Methods: Twenty NPC specimens and 10 normal biopsy specimens were analyzed, and the expression of OPN and enhancer of zeste homolog 2 (EZH2) was examined by immunohistochemical staining. Moreover, the expression of EZH2 in NPC cell lines was examined using quantitative reverse transcription polymerase chain reaction and Western blot analysis in the presence of recombinant human (rh) OPN and specific inhibitors. NPC cell migration and invasion were evaluated using a transwell chamber in the presence...
