Inhibitory effects of si-NEAT1 on the progression of laryngeal squamous cell carcinoma are reversed by knockdown of miR-204-5p. (A) Transfection efficiency of inhibitor-miR-204-5p was evaluated using reverse transcription-quantitative PCR. (B) Cell proliferation was measured through MTT assay. Effect of miR-204-5p and NEAT1 on apoptosis was assessed through flow cytometry in (C) AMC-HN-3 and (D) Tu177 cells. (E) Statistical results of the effect of miR-204-5p and NEAT1 on cell migration. (F) Statistical results of the effect of miR-204-5p and NEAT1 on cell invasion. Effect of miR-204-5p and NEAT1 on the protein expression levels of cyclinD1, N-cadherin, vimentin, E-cadherin and Bax in (G) AMC-HN-3 and (H) Tu177 cells was analyzed through western blotting. *P<0.05. The data are presented as the mean ± SD of three independent experiments. OD, optical density; miR, microRNA; NC, negative control; si, small interfering RNA; NEAT1, nuclear enriched abundant transcript 1.
