The expression of oncogene c-myc and its role on human laryngeal cancer / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To detect the expression of oncogene c-myc and explore its role on human laryngeal cancer.@*METHOD@#The mRNA and of oncogene c-myc levels were detected in human laryngeal cancer tissues and laryngeal normal tissues by the means of real-time PCR and immunohistochemistry, respectively.@*RESULT@#Compared with normal laryngeal tissues, the mRNA and protein levels of oncogene c-myc were both upregulated in laryngeal cancer tissues of all differentiation degree (P<0.05). Moreover, the level of c-myc was inverse correlated with the differentiation degree in human laryngeal cancer tissues.@*CONCLUSION@#The oncogene c-myc is overexpressed in human laryngeal cancer tissues, and c-myc may play an important role in carcinogenesis and progression of human laryngeal cancer tissues. It may provide a new target for gene therapy of human laryngeal cancer.
