Abstract

Objective: Shikonin, an active compound from the rhizome of Lithospermum erythrorhizon, exerts anti-tumor effects in various cancers, including glioblastoma multiforme (GBM). This study explored the mechanism of Shikonin for inhibiting the migration and invasion of GBM cells, providing a rationale for developing novel glioma therapies.

Methods: The effects of Shikonin on GBM cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) were detected by CCK-8, scratch wound-healing, Transwell, and Western blot assays. The effect of Shikonin on miR-361-5p expression in GBM cells was examined by RT-qPCR and the effect of miR-361-5p inhibitor transfection on proliferation, migration, invasion, and EMT in Shikonin-treated GBM cells was examined. Shikonin's target genes were identified and validated using dual luciferase reporter gene assay and chromatin immunoprecipitation (ChIP) assay, focusing on its induction of miR-361-5p expression. The downstream target genes of miR-361-5p were also identified and validated under Shikonin action. A GBM cell nude mouse xenograft tumor was established to confirm the regulatory role of Shikonin.

Results: Shikonin inhibited cell proliferation, migration, invasion, and EMT and upregulated miR-361-5p expression in GBM cells. Shikonin upregulated the glioma-associated protein p53, which promoted miR-361-5p transcription. miR-361-5p inhibited ZEB1 expression. Therefore, Shikonin inhibited GBM cell proliferation, migration, invasion, and EMT via p53/ miR-361-5p/ ZEB1 axis in vitro and in vivo.

Conclusion: Shikonin suppresses glioma cell proliferation, migration, invasion, and EMT by inhibiting ZEB1 expression through the p53/miR-361-5p axis.
