PG - 826-836 LID - 10.1080/15384047.2018.1564569 [doi] AB - Laryngeal squamous cell carcinoma (LSCC) accounts for 95% of laryngeal cancer incidence. Tobacco use has been shown to have a linear association with the development of the disease. While early diagnosis and treatment of LSCC are critical in improving the 5-year survival rate and quality of life, diagnosis of early-stage LSCC remains challenging because of the unapparent symptoms. Here, we report that miR-506, a critical regulator in many types of cancers, is aberrantly suppressed in LSCC patient tissues and cultured cancer cells. This is likely responsible for the enhanced production of YAP1 protein, a transcriptional factor that is well known for its oncogenic roles in LSCC malignancy. Statistical analysis has confirmed that the expression levels of miR-506 and YAP1 are strongly correlated with the malignant statuses of patient tumors. Restoring the expression level of miR-506 in cultured LSCC cells significantly inhibited proliferation, migration and invasion of the cells. The miR-506 and YAP1 regulatory network seems to affect at least pathways involved in apoptosis. Our study, for the first time, has demonstrated a tumor suppressive role of miR-506 in LSCC. This opens new opportunities for further exploring the molecular details of the development of the disease and thus will facilitate the development of novel diagnosis and therapeutic strategies.
