miR-129-5p has been reported to be abnormally expressed and plays an important role in the progression of various malignancies. However, its role in gliomas and its exact molecular mechanism need further research.
RT-qPCR was performed to evaluate miR-129-5p and HOXC10 mRNA expression levels in tissues and cell lines. Cell proliferation was detected via Cell Counting Kit-8 (CCK-8), 5-ethynyl-2'-deoxyuridine (EdU) and clone formation assays. Luciferase assays were used to validate the binding of seeds between miR-129-5p and HOXC10. A tumor xenograft model was developed to study the effect of miR-129-5p on glioma growth in vivo.
miR-129-5p was expressed at low levels in glioma tissues and cell lines. miR-129-5p overexpression inhibited glioma proliferation, migration and invasion. miR-129-5p negatively and directly targeted HOXC10. At the same time, HOXC10 was upregulated in glioma cancer, and HOXC10 knockdown inhibited cell proliferation, migration and invasion.
miR-129-5p inhibits glioma development by altering HOXC10 expression and may therefore serve as a new diagnostic marker and therapeutic target for glioma in the future.
miR-129-5p 表达异常,在多种恶性肿瘤的进展中发挥重要作用。然而,其在神经胶质瘤中的作用及其确切的分子机制仍需进一步研究。
采用 RT-qPCR 检测组织和细胞系中 miR-129-5p 和 HOXC10 mRNA 表达水平。通过细胞计数试剂盒-8(CCK-8)、5-乙炔基-2'-脱氧尿苷(EdU)和克隆形成实验检测细胞增殖。通过荧光素酶报告实验验证 miR-129-5p 和 HOXC10 之间种子区的结合。建立肿瘤异种移植模型研究 miR-129-5p 对体内神经胶质瘤生长的影响。
miR-129-5p 在神经胶质瘤组织和细胞系中低表达。miR-129-5p 过表达抑制神经胶质瘤增殖、迁移和侵袭。miR-129-5p 负向且直接靶向 HOXC10。同时,HOXC10 在神经胶质瘤中上调,HOXC10 敲低抑制细胞增殖、迁移和侵袭。
miR-129-5p 通过改变 HOXC10 的表达抑制神经胶质瘤的发展,因此可能成为未来神经胶质瘤的新诊断标志物和治疗靶点。
