Nanotechnology-based cancer chemoprevention in glioblastoma

Area of Science:

• Oncology
• Nanomedicine
• Biotechnology

Background:

• Glioblastoma is a heterogeneous brain tumor characterized by rapid progression, drug resistance, and recurrence.
• Key factors contributing to glioblastoma's aggressiveness include rapid growth, apoptosis evasion, pro-survival signaling, and infiltration of brain structures.

Purpose of the Study:

• To explore the potential of nanotechnology in overcoming current therapeutic limitations for glioblastoma.
• To highlight how nanoparticles (NPs) can enhance drug delivery and treatment efficacy for brain tumors.

Main Methods:

• Utilizing nanoparticle-based nanovectors for improved drug payload delivery.
• Employing NPs to enhance cellular drug uptake and enable delivery of nucleic acids (siRNAs) and peptides.
• Investigating the role of metal NPs in enhancing diagnostic imaging like magnetic resonance imaging (MRI).
• Exploring targeted co-administration strategies involving chemoprevention, near-infrared (NIR) or radiotherapy (RT).

Main Results:

• Nanoparticles facilitate crossing the blood-brain barrier, improving drug delivery to brain tumors.
• NPs enhance cellular uptake and enable the delivery of therapeutic agents like siRNAs to overcome glioblastoma resistance.
• Metal NPs improve MRI contrast for better tumor visualization.
• Nanotechnology supports targeted combination therapies, including chemoprevention and radiotherapy.

Conclusions:

• Nanotechnology presents multifaceted solutions to combat glioblastoma by addressing drug delivery, resistance, and imaging challenges.
• NPs offer a promising platform for developing advanced and effective glioblastoma treatment strategies.
• The integration of nanotechnology in glioblastoma therapy holds significant potential for improved patient outcomes.
