Abstract

The isocitrate dehydrogenase (IDH1/2) mutations are frequent genetic abnormalities in the majority of WHO grade II/III glioma and secondary GBM. IDH1-mutated (IDH1Mut) glioma exhibits distinctive patterns in Cancer biology and metabolism. In the present study, we showed that bone morphogenetic proteins (BMP4) are significantly upregulated in IDH1Mut glioma. Further, we demonstrated that cancer-associated BMP4 is secreted to tumor microenvironment, which enhances the tumor migration and invasion through an autocrine manner. Mechanistically, BMP4 activates its receptor and concomitant SMAD1/5/8 signaling, which potentiates Wnt/β-catenin signaling by enhancing Frizzled receptor expression. LDN-193189, a selective BMP Receptor inhibitor, prolonged the overall survival of mice bearing IDH1-mutated intracranial xenografts by limiting BMP/catenin signaling. These findings demonstrate the pivotal role of BMP4 on tumor aggressiveness in IDH1Mut gliomas, suggesting a possible therapeutic strategy for this type of malignancy.
