: Invasion is an important characteristic of the malignancy of glioblastoma (GBM) and a significant prognostic factor. Sempervirine (SPV), a yohimbine-type alkaloid, has been proven to inhibit GBM cells proliferation in previous research and found to have a potential effect in anti-invasion, but its mechanism of anti-invasion is still unknown. : To explore its pharmacodynamics in inhibiting GBM cell invasion in this study, we combined network pharmacology and bioinformatics to comprehensive exploratory analysis of SPV and verified the mechanism in vitro. : Firstly, targets of SPV and invasion-related genes were collected from public databases. Moreover, GBM samples were obtained to analyze differentially expressed genes (DEGs) from The Cancer Genome Atlas (TCGA). Then, the relevant targets of SPV inhibiting GBM invasion (SIGI) were obtained through the intersection of the three gene sets. Further, GO and KEGG analysis showed that the targets of SIGI were heavily enriched in the AKT signaling pathway. Subsequently, based on the method of machine learning, a clinical prognostic model of the relevant targets of SIGI was constructed using GBM samples from TCGA and the Gene Expression Omnibus (GEO). A four-genes model (, , , and ) was successfully constructed, and Vina Scores of MMP2 and MMP13 in molecular docking were higher, which may be the main targets of SIGI. Then, the effect of SIGI was confirmed via functional experiments on invasion, migration, and adhesion assay, and the effect involved changes in the expressions of p-AKT, MMP2 and MMP13. Finally, combined with AKT activator (SC79) and inhibitor (MK2206), we further confirmed that SPV inhibits GBM invasion through AKT phosphorylation. : This study provides valuable and an expected point of view into the regulation of AKT phosphorylation and inhibition of GBM invasion by SPV.
侵袭是胶质母细胞瘤(GBM)恶性程度的重要特征和重要的预后因素。育亨宾类生物碱永生碱(SPV)在先前的研究中已被证明可抑制GBM细胞增殖,并发现其具有潜在的抗侵袭作用,但其抗侵袭机制仍不清楚。:在本研究中,为了探索其抑制GBM细胞侵袭的药效学,我们结合网络药理学和生物信息学对SPV进行综合探索性分析,并在体外验证其机制。:首先,从公共数据库中收集SPV的靶点和侵袭相关基因。此外,获取GBM样本以分析来自癌症基因组图谱(TCGA)的差异表达基因(DEG)。然后,通过三个基因集的交集获得SPV抑制GBM侵袭的相关靶点(SIGI)。进一步的基因本体(GO)和京都基因与基因组百科全书(KEGG)分析表明,SIGI的靶点在AKT信号通路中高度富集。随后,基于机器学习方法,使用来自TCGA和基因表达综合数据库(GEO)的GBM样本构建了SIGI相关靶点的临床预后模型。成功构建了一个四基因模型(、、和),分子对接中基质金属蛋白酶2(MMP2)和基质金属蛋白酶13(MMP13)的虚拟筛选评分较高,这可能是SIGI的主要靶点。然后,通过侵袭、迁移和黏附实验的功能实验证实了SIGI的作用,且该作用涉及p - AKT、MMP2和MMP13表达的变化。最后,结合AKT激活剂(SC79)和抑制剂(MK2206),我们进一步证实SPV通过AKT磷酸化抑制GBM侵袭。:本研究为SPV调节AKT磷酸化和抑制GBM侵袭提供了有价值且预期的观点。
