Advances in HSP27 and HSP90-targeting strategies for glioblastoma

Abstract

Glioblastoma (GBM) is the most common and malignant primary brain tumor in adults. There is a critical need for novel strategies to abolish the molecular mechanisms that support GBM growth, invasion and treatment resistance. The heat shock proteins, HSP27 and HSP90, serve these pivotal roles in tumor cells and have been identified as effective targets for developing therapeutics. Natural and synthetic inhibitors have been evaluated in clinical trials for several forms of systemic cancer but none as yet for GBM. This topic review summarizes the current preclinical evidence and rationale to define the potential of HSP27 and HSP90 inhibitors in GBM management.
