Abstract:MicroRNA (miRNA) is a class of endogenous non-coding RNA which found in eukaryotes and has regulatory function. Its size is about 20 to 25 nucleotides. Recent study found that miRNA is closly related to the EBV, LMP1, signal transduction pathway, tumor-associated gene network, cell mitosis, tumor angiogenesis, tumor invasion and metastasis of nasopharyngeal. Therefore, studing the relationship between miRNA and nasopharyngeal will help to deepen the understanding of its pathogenesis, and also will provide new inspiration and basis for clinical diagnosis and treatment.

Key words:Nasopharyngeal neoplasms,MicroRNAs
