MicroRNAs (miRNAs) are small, noncoding RNAs of endogenous origin that play an important role in tumor development. Here, we examined the role of miR-152 in supragalottic laryngeal carcinoma. The expression of miR-152 was assessed by real-time PCR in tissues from 83 patients with supragalottic laryngeal carcinoma in relation to clinicopathological parameters. Cell viability was assessed by thiazolyl blue assay in Hep-2 cells transfected with miR-152 mimics or a negative control. MiR-152 was significantly downregulated in supragalottic laryngeal carcinoma tissues (t = 12.65, p < 0.001, paired t test), and its expression was correlated with pT stage (χ(2) = 26.88, p < 0.001) and pN stage (z = -3.56, p < 0.001) in patients with supragalottic laryngeal carcinoma. MiR-152 inhibited the proliferation of Hep-2 cells. MiR-152 may serve as a novel prognostic marker in patients with supragalottic laryngeal carcinoma.
