TUBB2B regulates epithelial-mesenchymal transition via interaction with Vimentin to promote glioma migration and invasion

Abstract Background Epithelial-mesenchymal transition (EMT) plays a crucial role in the migration and invasion capabilities of glioblastoma (GBM) cells. Several studies have established tubulin as a significant regulator of the EMT process. Tubulin beta 2B class IIb (TUBB2B), a critical component of...

description Abstract Background Epithelial-mesenchymal transition (EMT) plays a crucial role in the migration and invasion capabilities of glioblastoma (GBM) cells. Several studies have established tubulin as a significant regulator of the EMT process. Tubulin beta 2B class IIb (TUBB2B), a critical component of microtubules, has been linked to the prognosis of various tumors. However, the specific biological function and mechanism of TUBB2B in GBM remain unclear. Methods In vitro experiments demonstrated that TUBB2B knockdown inhibited the migration and invasion of GBM cells, while its overexpression enhanced these capabilities. Western blot, immunofluorescence (IF) and co-immunoprecipitation (Co-IP) assays revealed that TUBB2B interacts with Vimentin. Molecular docking and residue mutation scanning indicated that TUBB2B interacts with Vimentin at the R391/K392/A393/F394 sites. In vivo experiments using nude mice confirmed that TUBB2B knockdown inhibited GBM cell invasion and migration. Results TUBB2B was upregulated in GBM tissue samples compared with normal tissues. The sites of TUBB2B(R391/K392/A393/F394) physically interacts with Vimentin to induce EMT, which promotes migration and invasion. Conclusion TUBB2B may regulate EMT and promote the migration and invasion of GBM cells through its interaction with Vimentin, highlighting TUBB2B as a potential therapeutic target for GBM.
