Glioblastomas (GBMs) remain one of the most deadly cancers with modest advances in overall survival despite significant improvements in imaging, surgery, and molecular genomic understanding. The highest grade glioma, GBM is a primary brain cancer that is molecularly heterogeneous among patients and even within the same patient. Key hallmarks include glioma cell invasion, angiogenesis, and therapeutic resistance. While once considered a major player in glioma invasion, members of the matrix metalloproteinase (MMP) family are also associated with other key pathological hallmarks of glioma. Investigations into understanding MMP function in GBM were slowed due to the failed MMP inhibitor trials for GBM in the 2000s. In contrast, the field of MMPs in other brain pathologies has flourished in areas such as traumatic brain injury, multiple sclerosis, and stroke. In the past decade the increase in publicly available datasets documenting patient biopsy molecular information has empowered laboratory investigations into the spectrum of genomic, transcriptomic, and proteomic changes associated with glioma, including MMPs. In this review, we selected one of these datasets to illustrate a small sample of information that can be obtained from such analyses. Combined with recent reports on the use of MMP cleavable peptides for imaging and the multifunctionality of MMPs, including intracellular non-proteolytic actions in various cell types, this paves the way for new avenues of MMP research. Understanding the function of MMPs in host/tumour interactions both spatially and temporally during tumour progression and in response to treatment will be crucial for the advancement of targeting specific MMPs in GBM. The opportunities to further explore MMP regulation, expression, and function in GBM have never been so great with progress in modern bioinformatics and molecular techniques, and it is hoped that advancements will translate in some way to patients diagnosed with GBM.
