LID - BSR20191348 [pii] LID - 10.1042/BSR20191348 [doi] AB - BACKGROUND: The effect of miR-182 on the expressions of CRR9 in laryngeal squamous cell carcinoma (LSCC) cells, and the impact on invasion and metastasis of LSCC were investigated in the present paper. METHODS: The expressions of miR-182 in LSCC tissue and cell line were detected by RT-qPCR. MTT assay and Annexin V staining were used to detect the effects of miR-182 on tumor cells proliferation. Target gene prediction and screening, and luciferase reporter assay were designed to verify downstream target genes of miR-182. The mRNA and protein expressions of CRR9 were detected by qRT-PCR and Western blot. Finally, the expressions of CRR9 were measured by transfecting cells with miR-182 in mice. RESULTS: Compared with normal tissue and cell, the expressions of miR-182 in tumor tissues and cells were much lower. Over-expressions of miR-182 can increase apoptosis rate. Luciferase reporter assay revealed that CRR9 was a downstream gene of miR-182. Reintroduction of CRR9 abolished miR-182-induced LSCC cell growth inhibition. In animal models, over-expressions of miR-182 can reduce tumor weight and promote apoptosis. CONCLUSION: miR-182 can inhibit the proliferation of LSCC cells by directly inhibiting the expressions of CRR9, thereby suppressing the occurrences and developments of LSCC.
