Abstract

Glioblastoma (GBM) is the most prevalent and fatal form of brain tumor, which is associated with a poor prognosis. ATP-binding cassette subfamily F member 1 (ABCF1) is an E2 ubiquitin-conjugating enzyme, which is implicated in regulating immune responses and tumorigenesis. Aberrant E3 ubiquitylation has been evidenced in GBM. However, the role of ABCF1 in GBM needs to be further explored. The expression of ABCF1, CXC chemokine ligand 12 (CXCL12), and CXC chemokine receptor 4 (CXCR4) in GBM tissues was examined by the GEPIA tool, real-time PCR and Western blotting. HMC3, U251MG, and LN-229 cells were cultured and transfected with shRNA targeting ABCF1 and ABCF1 plasmids. The proliferative, migrative, and invasive ability of cells was detected. Western blotting was used to detect the levels of phosphorylated phosphatidylinositol 3-kinase (PI3K) and phosphorylated protein kinase B (AKT). We observed that GBM tissues had higher ABCF1, CXCL12, and CXCR4 expression levels. The expression levels of CXCL12 and CXCR4 were enhanced by ABCF1 overexpression, which were significantly reversed by silence of ABCF1 in GBM cells. Silencing ABCF1 or CXCR4 inhibition weakened the capacity of GBM cell growth, migration, and invasion, while ectopic ABCF1 expression or CXCL12 treatment enhanced the cellular function of GBM cells. Furthermore, p-PI3K and p-AKT protein levels were downregulated by ABCF1 knockdown or CXCR4 blockade, which were prompted by ABCF1 overexpression or CXCL12 supplement. The ABCF1-CXCL12-CXCR4 axis was identified as a key player in GBM cell survival and metastasis by activating the PI3K/AKT signaling pathway in GBM cells.

摘要

胶质母细胞瘤(GBM)是最常见和致命的脑肿瘤形式,预后不良。ATP 结合盒亚家族 F 成员 1(ABCF1)是一种 E2 泛素连接酶,参与调节免疫反应和肿瘤发生。已经在 GBM 中证实了异常的 E3 泛素化。然而,ABCF1 在 GBM 中的作用需要进一步探索。使用 GEPIA 工具、实时 PCR 和 Western blot 检测 GBM 组织中 ABCF1、CXC 趋化因子配体 12(CXCL12)和 CXC 趋化因子受体 4(CXCR4)的表达。培养 HMC3、U251MG 和 LN-229 细胞,并转染靶向 ABCF1 的 shRNA 和 ABCF1 质粒。检测细胞的增殖、迁移和侵袭能力。Western blot 用于检测磷酸化磷脂酰肌醇 3-激酶(PI3K)和磷酸化蛋白激酶 B(AKT)的水平。我们观察到 GBM 组织中 ABCF1、CXCL12 和 CXCR4 的表达水平较高。ABCF1 过表达增强了 CXCL12 和 CXCR4 的表达水平,而在 GBM 细胞中沉默 ABCF1 则显著逆转了这种情况。沉默 ABCF1 或抑制 CXCR4 削弱了 GBM 细胞生长、迁移和侵袭的能力,而异位表达 ABCF1 或用 CXCL12 处理则增强了 GBM 细胞的细胞功能。此外,ABCF1 敲低或 CXCR4 阻断下调了 p-PI3K 和 p-AKT 蛋白水平,而 ABCF1 过表达或 CXCL12 补充则促进了这些蛋白水平。ABCF1-CXCL12-CXCR4 轴通过激活 GBM 细胞中的 PI3K/AKT 信号通路,被鉴定为 GBM 细胞存活和转移的关键因素。
