摘要:

目的: 探讨微小RNA(microRNA, miRNA)-337-3p在口腔鳞状细胞癌(oral squamous cell carcinoma, OSCC)组织中的表达及其临床意义。方法: 收集20例OSCC患者的术后标本,检测癌组织及癌旁正常组织中的miRNA-337-3p表达水平,分析其表达水平与患者临床病理参数间的相关性;采用划痕试验评估miRNA-337-3p对OSCC细胞株HN30迁移能力的影响,探索可能的分子机制。结果: 与癌旁正常组织相比,OSCC组织中的miRNA-337-3p呈显著低表达(P<0.000 1),且其表达水平与OSCC患者淋巴结转移状况显著相关(P<0.05);与未发生淋巴结转移的患者(N0)相比,发生淋巴结转移(N1+N2)患者的OSCC组织中miRNA-337-3p表达水平显著降低(P<0.05)。在HN30细胞中,过表达miRNA-337-3p的细胞迁移能力降低,抑制miRNA-337-3p表达,则细胞迁移能力上升。miRNA-337-3p可抑制基质金属蛋白酶14 (matrix metalloproteinase-14,MMP-14)蛋白的表达。结论: miRNA-337-3p在OSCC中发挥抑癌作用,其可能具有抑制OSCC细胞侵袭及转移的功能,其有望成为OSCC侵袭、转移的早期诊断标志物及为预后监测提供帮助。

Abstract:

Objective: To investigate the expression of microRNA (miRNA)-337-3p in oral squamous cell carcinoma (OSCC) and its clinical significance. Methods: The expression of miRNA-337-3p in OSCC cancer and paracancerous tissue of 20 OSCC patients was determined, and the correlation of miRNA-337-3p expression with clinical-pathological parameter was analyzed. Scratch test was performed to detect the effect of miRNA-337-3p on migration ability of OSCC cell line HN30 cells, and the possible molecular mechanism was explored. Results: Expression of miRNA-337-3p in OSCC was significantly lower than that in paracancerous tissue(P<0.000 1), and was correlated significantly with the status of lymph node metastasis (P<0.05). Patients with lymph node metastasis (N1+N2) had a lower expression level of miRNA-337-3p than those without lymph node metastasis (N0). Overexpression of miRNA-337-3p in HN30 cells inhibited cell migration, whereas suppression of miRNA-337-3p led to increase of cell migration. miRNA-337-3p could inhibit the expression of matrix metalloproteinase-14 (MMP-14). Conclusions: miRNA-337-3p plays a suppressive role in OSCC, inhibitingthe invasion and metastasis of OSCC cells, and is expected to be used as a biomarker for assessing the invasion and metastasis of OSCC and helping the monitoring of prognosis.
