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 aryngeal cancer.Method:The mRNA and of oncogene c-myc levels were detected in human laryngeal cancer tissues and iaryngeal 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 e-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.
