转移是头颈部鳞状细胞癌(HNSCC)进展的关键事件。为了鉴定与HNSCC转移相关的microRNA,检查了具有不同转移潜力的6对HNSCC细胞系。使用微阵列,鉴定了一组差异表达的microRNA,包括高转移性细胞中miR-138的减少。miR-138的异位转染抑制了细胞侵袭,并导致细胞周期停滞和凋亡。miR-138的敲低增强细胞侵袭并抑制细胞凋亡。因此,我们的研究结果表明,miR-138作为肿瘤抑制剂,并可能作为HNSCC患者转移风险的治疗靶点。
Metastasis is a critical event in the progression of head and neck squamous cell carcinoma (HNSCC). To identify microRNAs associated with HNSCC metastasis, 6 paired HNSCC cell lines with different metastatic potential were examined. Using microarrays, a panel of differentially expressed microRNAs was identified, including reduction of miR-138 in highly metastatic cells. Ectopic transfection of miR-138 suppressed cell invasion and led to cell cycle arrest and apoptosis. Knockdown of miR-138 enhanced cell invasion and suppressed apoptosis. Thus, our results suggested miR-138 acts as a tumor suppresser and may serve as a therapeutic target for HNSCC patients at risk of metastasis.
