Abstract

After the expression level of lncRNA AC023794.4‑201 was upregulated in 2 laryngeal squamous cell carcinoma (LSCC) cell lines (AMC‑HN‑8 and TU‑212) and LSCC xenografts, the biological function of lncRNA AC023794.4‑201 in LSCC was further investigated using in vitro and in vivo experiments, such as cell function experiments and nude mice transplantation. In our previous study, it was demonstrated that the expression level of the long non‑coding RNA (lncRNA) AC023794.4‑201 were decreased in laryngeal squamous cell carcinoma, particularly in cases of LSCC with lymphatic metastasis. Moreover, low expression levels of AC023794.4‑201 were revealed to be an adverse prognostic factor for patients with LSCC. In the present study, lentiviruses were used to overexpress AC023794.4‑201 before a series of cell function assays were performed and a xenograft nude mouse model was constructed, in order to further investigate the functions of AC023794.4‑201 in LSCC. AC023794.4‑201 inhibited the proliferation and the cloning capacity of LSCC cells compared with the negative control group as indicated by real‑time cell analysis and the plate colony formation assay. Flow cytometry and transwell migration assays demonstrated that AC023794.4‑201 inhibited the migration, induced cell cycle arrest and increased the apoptotic rate of LSCC cells. The results of the in vivo studies demonstrated that AC023794.4‑201 significantly inhibited the growth of LSCC xenografts, and promoted apoptosis. In conclusion, the findings of the present study suggested that AC023794.4‑201 may exert tumor‑suppressive functions in the progression of LSCC and may serve as a potential prognostic biomarker for LSCC.
