Transferrin receptors are highly expressed on glioblastoma cells, making them a target for therapy. Gallium can function as an iron mimetic that binds to transferring and is incorporated into the cells. The purpose of this study was to evaluate gallium maltolate in the treatment of a U87 xenograft brain tumor model by evaluating changes in tumor blood volume and enhancing tumor volume. The studies demonstrate treating tumors with the novel use of gallium maltolate provides inhibition of tumor volume and angiogenesis.
