Previous research has shown that microRNA 506 (miR-506) functions as an essential modulator in the development of many biological reactions, including multiple cancers. However, its involvement in cutaneous squamous cell carcinoma (CSCC) has been rarely reported. In the present work, we investigated the molecular mechanism and function of miR-506 in the regulation of CSCC cell viability and metastasis (migration and invasion). We observed that miR-506 expression was upregulated in both CSCC tissues and cell lines, and that decreased miR-506 expression led to repressed tumorigenesis in CSCC cells. Furthermore, flow cytometry revealed that the depletion of miR-506 resulted in decreased proliferation and increased apoptotic levels in CSCC cells. Meanwhile, it was found that miR-506 decreased CSCC cell migration and invasion in vitro. The dual-luciferase reporter assay also revealed that miR-506 targets the 3 '-UTRs of p65 and Laminin C1 (LAMC1) for silencing. Silencing of p65 expression counteracted the pro-apoptotic influence of miR-506 depletion in CSCC cells, while inhibition of LAMC1 expression restored the migration and invasion properties of the CSCC cells. Therefore, the results provide evidence for the need to probe the biological and molecular mechanisms behind the development and progression of CSCC and may lead to novel treatment CSCC strategies.
