摘要: 目的 口腔鳞状细胞癌 (oral squamous cell carcinoma, OSCC) 是一种复发率高、 转移率高、 预 后差的常见癌症, 研究旨在深入了解 RABL6 在 OSCC 肿瘤发生和发展及预后中的作用。 方法 采用定量逆 转录聚合酶链反应 (qRT-PCR) 和 Western 印迹检测 37 例冷冻临床样本和 OSCC 细胞中 RABL6 的表达。 分析 RABL6 的表达及其与临床病理特征的相关性。 通过 CCK-8、 克隆形成、 流式细胞术、 细胞划痕和 Transwell 实验, 研究 RABL6 基因敲低对 OSCC 细胞增殖、 凋亡和迁移能力的影响。 结果 与癌旁组织相比, RABL6 在 OSCC 组织中高表达, 与预后不良相关; 与正常口腔角质形成细胞相比, RABL6 在 OSCC 细胞中 高表达; 与 si-NC 组比较, 敲低 RABL6 抑制了 OSCC 细胞的增殖、 迁移和侵袭, 还能诱导细胞凋亡。 结论 RABL6 在 OSCC 中作为肿瘤癌基因发挥作用。 提示可作为预测预后的潜在生物标志物, 也是 OSCC 治疗 的新靶点。

Abstract: Objective Oral squamous cell carcinoma (OSCC) is a common cancer with high recurrence rate, high metastasis rate and poor prognosis. This study aims to further understand the role of RABL6 in the occurrence, development and prognosis of OSCC tumors. Methods The quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blotting were used to detect the expression of RABL6 in 37 frozen clinical samples and OSCC cells. The correlation between RABL6 expression and clinicopathologic features was assayed. The effects of RABL6 gene knockdown on the proliferation, apoptosis and migration of OSCC cells were studied by CCK-8, colony formation, flow cytometry, wound healing and transwell assay. Results Compared with the normal adjacent tissues, the OSCC tissues have higher expression level of RABL6, which is associated with poor prognosis. Compared with the normal oral keratinocytes group, the OSCC cells have higher expression level of RABL6. Knockdown of RABL6 inhibited the proliferation, migration and invasion of OSCC cells and induced apoptosis when compared with the si-NC group. Conclusion RABL6 acts as a tumor oncogene in OSCC, which can be a potential biomarker for predicting prognosis and a new target for OSCC therapy.
