This study aimed to develop and evaluate a nanotechnology-based therapeutic approach using selenium-loaded β-cyclodextrin-combretastatin A-4 nanoparticles (Se(B-CD-CA-4-NPs)) to overcome these limitations and enhance treatment efficacy.  \nMethods The Se(B-CD-CA-4-NPs) complex was synthesized and characterized for morphology, size, stability, and selenium loading capacity. In vitro studies included MTTassay, cell apoptosis, scratch assay, gelatin zymography, and qPCR were used to assess the effect of the newly synthesized complex on U-87MG glioblastoma cell viability, cell death, migration, MMP-2 and MMP-9 activity, and mRNA expression level of apoptosisrelated genes.  \nResults The nanoparticles exhibited a spherical morphology (25 .78 ± 3.4 nm), negative surface charge, and high stability. The IC50 of the synthesized complex was 1.629 μM in U-87MG cancer cells. The Se(B-CD-CA-4-NPs) complex significantly reduced U-87MG cell viability, migration and invasion. Additionally, the complex induced cell apoptosis via upregulation of the BAX/BCL-2 ratio in cancer cells. Moreover, the Se(B-CD-CA- 4-NPs) complex inhibited metastasis by suppressing the activity and expression of MMP-2 and MMP-9 .  \nConclusion The Se(B-CD-CA-4-NPs) complex represents a promising multifunctional therapeutic agent for GBM, offering enhanced proapoptotic property, selective tumor targeting, and reduced toxicity.  \nKeywords Se(B-CD-CA-4-NPs) complex, Metastasis, Glioblastoma, Apoptosis, MMPs  \n© The Author(s) 2025.
