Abstract 2935: Novel combination of repurposed drugs induces complete cell invasion arrest of glioblastoma in vitro

2019

Abstract Introduction: Glioblastoma multiforme (GBM) is an aggressive and lethal cancer with a poor prognosis even after conventional treatment (surgery, radiation, chemotherapy). Temozolomide (TMZ) is a standard cyotoxic agent used, despite resistance leading to recurrence. Therefore, additional strategies for targeting the tumor environment are needed. We demonstrate a combination of approved drugs (CAD) repurposed to target GBM leads to complete arrest of GBM cell invasion. Each drug in the combination individually targets diverse tumor pathways: 1) invasion via MMP2 (doxycycline); 2) angiogenesis, inflammation, and proliferation via p53-dependent G1 cell-cycle arrest (celecoxib); 3) aut…
