摘要: 目的: 探讨miR-181a-5p对口腔癌细胞系CAL-27与人系带血管内皮细胞(HUVEC)之间融合的影响。方法: 通过对CAL-27和HUVEC进行稳定转染绿色荧光蛋白和红色荧光蛋白,证实CAL-27和HUVEC有自发融合的现象存在,并通过实时定量PCR检测HUVEC内miR-181a-5p 的表达,通过瞬时转染 HUVEC miR-181a-5p inhibitor后检测miR-181a-5p的表达情况;并通过人工计数和流式细胞术分析融合情况。结果: CAL-27能与HUVEC发生融合。通过降低miR-181a的表达, 发现CAL-27与HUVEC的融合率升高(P<0.05)。结论: miR-181a-5p与细胞融合相关,降低miR-181a-5p表达能增加CAL-27与HUVEC融合的发生。

Abstract: Objective: To investigate the effect of miR-181a-5p on the fusion between oral cancer cell line CAL-27 and human vascular endothelial cells (HUVECs). Methods: The spontaneous cell fusion of CAL-27 and HUVEC was confirmed by the stable transfection of CAL-27 and HUVEC with green fluorescent protein and red fluorescent protein. The expression of miR-181a-5p in HUVEC was detected by real-time PCR. The expression of miR-181a-5p after HUVEC miR-181a-5p inhibitor infection was analyzed. The fusion was analyzed by manual counting and flow cytometry. Results: CAL-27 could fuse with HUVEC. By reducing the expression of miR-181a-5p, it was found that the fusion rate of CAL-27 and HUVEC increased (P<0.05). Conclusion: miR-181a-5p is associated with cell fusion, and the decrease of miR-181a-5p can increase the fusion of OSCC and HUVEC.
