•Glioblastoma multiforme (GBM) is the most prominent brain tumor of adults, endowed with tremendous invasive capacity, high aggressiveness and resistance to chemo and radiotherapy.•Overexpression of EGFR (epidermal growth factor receptor) is reported in more than 60% of primary GBM cases.•The miRNA interacts with mRNA either at its 3’ UTR region to suppress or at 5’UTR region to favor expression levels.•The miRNAs are pro or anti-oncogenic and that repression of oncogenic miRNAs with antisense technology can mitigate the glioblastomas•Nanomedicine provides new avenues for site specific delivery of miRNAs or anti-miRNAs alone or in combination with other therapeuticals within the brain for optimal therapeutic responses.
Glioblastoma multiforme (GBM) is the most aggressive (WHO grade IV) form of diffuse glioma endowed with tremendous invasive capacity. The availability of narrow therapeutic choices for GBM management adds to the irony, even the post-treatment median survival time is roughly around 14-16 months. Gene mutations seem to be cardinal to GBM formation, owing to involvement of amplified and mutated receptor tyrosine kinase (RTK)-encoding genes, leading to dysregulation of growth factor signaling pathways. Of-late, the role of different microRNAs (miRNAs) in progression and proliferation of GBM was realized, which lead to their burgeon potential applications for diagnostic and therapeutic purposes. miRNA signatures are intricately linked with onset and progression of GBM. Although, progression of GBM causes significant changes in the BBB to form BBTB, but still efficient passage of cancer therapeutics, including antibodies and miRNAs are prevented, leading to low bioavailability. Recent developments in the nanomedicine field provide novel approaches to manage GBM via efficient and brain targeted delivery of miRNAs either alone or as part of cytotoxic pharmaceutical composition, thereby modulating cell signaling in well predicted manner to promise positive therapeutic outcomes.
