Intracellular vimentin overexpression has been associated with
epithelial-mesenchymal transition, metastasis, invasion, and proliferation, but
cell surface vimentin (CSV) is less understood. Furthermore, it remains unknown
whether CSV can serve as a therapeutic target in CSV-expressing tumor cells. We
found that CSV was present on glioblastoma multiforme (GBM) cancer stem cells and
that CSV expression was associated with spheroid formation in those cells. A
newly developed monoclonal antibody against CSV, 86C, specifically and
significantly induced apoptosis and inhibited spheroid formation in GBM cells in
vitro. The addition of 86C to GBM cells in vitro also led to rapid
internalization of vimentin and decreased GBM cell viability. These findings were
associated with an increase in caspase-3 activity, indicating activation of
apoptosis. Finally, treatment with 86C inhibited GBM progression in vivo. In
conclusion, CSV-expressing GBM cells have properties of tumor initiating cells,
and targeting CSV with the monoclonal antibody 86C is a promising approach in the
treatment of GBM.
