Exogenous miR-223 attenuates nasopharyngeal tumor growth in mouse xenograft models. a. The appearance of xenograft subcutaneous NPC in miR-223 mimics transfection and control groups. b. Growth curves of subcutaneous NPC in nude mice with miR-223 mimics transfection revealed that tumor growth significantly slowed down compared with control group. c. Total tumor weight of miR-223 mimic transfection and control groups. d. HE staining result of the tumor formed in nude mice using, all of them were typical nasopharyngeal squamous cell carcinoma. The data were showed as means ± SD (n = 7). * and ** indicate P < 0.05 and P < 0.01 as compared with control group
