摘要:

目的 探讨微小RNA(miR)-378-5p对胶质瘤血管生成的作用及其分子机制。 方法 qRT-PCR检测胶质瘤细胞miR-378-5p的表达水平。ELISA检测肿瘤细胞上清液中血管内皮生长因子A(VEGF-A)的含量。收集胶质瘤细胞上清液并制成条件培养基培养HUVECs,采用CCK-8、Transwell实验和小管形成实验检测HUVECs增殖、迁移、侵袭和血管形成能力的影响,评估miR-378-5p对HUVECs生物学行为的影响。 结果 在4个胶质瘤细胞中U251的miR-378-5p表达量最高,而U87 MG的表达量最低。miR-378-5p表达量高的肿瘤细胞,其条件培养基可显著促进HUVECs增殖、迁移、侵袭和血管生成。反之,降低肿瘤细胞miR-378-5p的表达量,其条件培养基促进HUVECs增殖、迁移、侵袭和血管生成的能力显著下降。ELISA结果显示miR-378-5p促进胶质瘤细胞释放VEGF-A。使用VEGF-A中和抗体干预条件培养基后,HUVECs迁移、侵袭和血管生成能力显著下调。反之外源性添加VEGF-A则可以显著提高HUVECs、迁移、侵袭和血管生成能力。 结论 miR-378-5p通过增加胶质瘤细胞释放VEGF-A,进而促进HUVECs增殖、迁移、侵袭和血管生成。

Abstract:

Objective To investigate the effect of miR-378-5p on glioma angiogenesis and its molecular mechanism. Methods The expression of miR-378-5p were detected by qRT-PCR in four glioma cells. The levels of VEGF were analyzed by ELISA. HUVECs were treated conditioned medium which collected by glioma cells supernatant. The effects of miR-378-5p on the proliferation, migration, invasion, and angiogenesis of HUVECs were detected by CCK-8, Transwell assay, and tubular formation assay. Results U251 was the highest expression of miR-378-5p, while U87 MG was the lowest expression. Glioma-conditioned media increased miR-378-5p levels significantly promoted the proliferation, migration, invasion, and angiogenesis of HUVECs. The results were contrary with glioma-conditioned media decreased miR-378-5p levels. miR-378-5p promoted the release of VEGF-A from glioma cells. The proliferation, migration, invasion, and angiogenesis of HUVECs treated-VEGF neutralizing antibody were significantly downregulated. Conclusion miR-378-5p promoted HUVECs proliferation, migration, invasion, and angiogenesis by increasing the release of VEGF from glioma cells.
