MicroRNAs (miRNAs) are noncoding RNAs involved in posttranscriptional regulation of gene expression in cancer and provide new perspectives on the development of laryngeal squamous cell carcinoma (SCC). miRNA expression of 6 pairs of laryngeal SCC and adjacent normal tissues was screened using miRNA array. Laser capture microdissection was applied to isolate a homogeneous group of cells from laryngeal SCC samples. The results of miRNA array analysis were validated in 48 pairs of laryngeal SCC and adjacent normal tissues using quantitative RT-PCR. Twenty-nine differentially expressed miRNAs were detected in the 6 pairs of laryngeal SCC, of which 6 were confirmed, including upregulation of miR-21, miR-93, miR-205, and miR-708 and downregulation of miR-125b and miR-145. Their putative target genes were predicted using 3 online software programs. These differentially expressed miRNAs may play a role in tumorigenesis and progression in laryngeal SCC and offer new angles for further investigations into the function of miRNAs.
