Resumen
ONX-0914 (PR957) is a proteasome subunit beta type-8 (PSMB8)-selective inhibitor. Previous studies have shown that inhibiting PSMB8 expression in a glioblastoma reduces tumor progression and angiogenesis. This study shows that ONX-0914 inhibits glioblastoma cell proliferation and induces cell death through apoptosis and autophagy via p53. In a mouse xenograft model, TMZ-combined ONX-0914 reduced tumor progression. This is the first study to evaluate the ONX-0914 function in glioblastomas.
