摘要: 目的:探讨鞘氨醇-1-磷酸受体4(sphingosine-1-phosphate receptor 4,S1PR4)在口腔鳞状细胞癌(oral squamous cell carcinoma,OSCC)中的表达及生物学功能。方法: 通过实时荧光定量PCR(RT-qPCR)、免疫印迹实验(Western blot)和免疫组织化学染色,分析OSCC组织样本及细胞系(WSU-HN4、WSU-HN6、CAL27、WSU-HN30)中S1PR4的表达。通过S1PR4拮抗剂(CYM50358)抑制S1PR4活性,利用CCK-8以及克隆形成实验检测CYM50358对OSCC细胞增殖的影响。通过流式细胞术分析CYM500358对OSCC细胞凋亡的影响。采用SPSS 23.0软件包对数据进行统计学分析。结果: OSCC中的S1PR4 转录及表达显著上调,CYM50358处理组OSCC细胞增殖活性显著低于空白对照组(P<0.05),CYM50358处理组OSCC细胞克隆形成能力显著低于空白对照组(P<0.05),CYM50358处理组OSCC细胞凋亡比例显著高于空白对照组(P<0.05)。结论: S1PR4在OSCC中表达上调,S1PR4拮抗剂可抑制OSCC细胞生长并促进细胞凋亡,或为OSCC的治疗提供新的潜在靶点。

Abstract: PURPOSE: To explore the expression and biological functions of sphingosine-1-phosphate receptor 4 (S1PR4) in oral squamous cell carcinoma (OSCC). METHODS: The expression of S1PR4 in OSCC tissue samples and cell lines (WSU-HN4, WSU-HN6, CAL27, WSU-HN30) was analyzed by RT-qPCR, Western blot and IHC. The activity of S1PR4 was inhibited by S1PR4 antagonist(CYM50358), and the effect of CYM50358 on proliferation of OSCC cells was detected by CCK-8 and clonal formation assay. The effect of CYM500358 on apoptosis of OSCC cells was evaluated by flow cytometry. SPSS 23.0 software package was used for statistical analysis. RESULTS: The transcription and expression of S1PR4 were up-regulated in OSCC. The activity of proliferation and clonality were decreased(P<0.05), while the percentage of apoptotic cells was increased in CYM50358-treated OSCC cells(P<0.05). CONCLUSIONS: The expression of S1PR4 is up-regulated in OSCC. S1PR4 antagonist can significantly reduce viability and promote apoptosis of OSCC cells, and may be a potential indicator for treatment of OSCC.
