PG - 444-451 LID - 10.1111/1440-1681.12890 [doi] AB - Laryngeal squamous cell carcinoma (LSCC) is one of the most common head and neck cancers, with high mortality and incidence. MicroRNA-26a (miR-26a) is involved in the development and progression of several tumours. However, the roles of miR-26a and its target CKS2 in LSCC progression are not yet clear. The mRNA and protein expression was determined using RT-PCR and Western blotting assay, respectively. Cell proliferation was detected using a Cell Counting kit-8 assay (CCK-8). Transwell assay was used to evaluate cell migration and invasion. Dual-luciferase reporter assay was applied to determine the relationship between miR-26a and CKS2. In addition, a tumour xenograft model in nude mice was established to further determine the effects of miR-26a on tumourigenesis. In this study, we found that miR-26a level was down-regulated in LSCC tissues and cell lines, while CKS2 expression was increased. Cell proliferation, migration, invasion and the expression of MMP2 and MMP9 was suppressed by miR-26a overexpression, but enhanced by inhibition of miR-26a. Dual-luciferase reporter assay demonstrated that CKS2 is a direct target of miR-26a in AMC-HN-8 cells. Overexpression of miR-26a caused a significant reduction in CKS2 expression, and reinforced expression of CKS2 abolished the tumour-suppressive function of miR-26a. Moreover, miR-26a inhibited tumour growth in vivo. Taken together, miR-26a inhibited proliferation and tumourigenesis of LSCC via targeting CKS2 in vitro and in vivo.
