[Research progress of microRNA in laryngeal squamous cell carcinoma].

Laryngeal carcinoma is one of the most common malignant tumors in the area of head and neck, and the main pathological type is laryngeal squamous cell carcinoma. Due to the fact that the disease usually have no overt clinical symptoms at the early stage and easy to relapse, it has a poor prognosis and low five-year survival rate. microRNA is a class of endogenous, non-coding RNA with a length of 19-25 nucleotides. microRNAs, mainly regulate the expression of target genes at the post-transcriptional level after complementing and pairing with the 3'-UTR area of the target gene. Studies have shown that the abnormal expression of microRNA is closely related to the occurrence, development, metastasis and prognosis of various cancers including laryngeal carcinoma. In this article, the research progress of microRNA in laryngeal squamous cell carcinoma is reviewed.
