Transforming RNA-Based Gene Therapy with Innovative Nanocarriers for siRNA and miRNA Delivery

Area of Science:

• Biotechnology
• Molecular Biology
• Nanomedicine

Background:

• Gene therapy using RNA, including small interfering RNA (siRNA) and microRNA (miRNA), shows promise for treating cancer and other disorders.
• A major challenge in RNA therapy is the efficient and stable delivery of siRNA and miRNA to target cells, hindered by carrier instability and poor cell membrane uptake.

Purpose of the Study:

• To provide a comprehensive overview of current and emerging nanocarrier technologies for microRNA and small interfering RNA delivery.
• To examine the operational principles, design, and applications of these nanocarriers in gene therapy.

Main Methods:

• Review of existing literature on nanocarrier technologies for RNA delivery.
• Focus on nanocarrier platforms demonstrating proof of concept in stability, controlled release, and delivery.
• Exploration of lipid-based nanoparticles, polymeric systems, and hybrid nanocarriers.

Main Results:

• Nanocarrier technologies offer significant improvements in the stability and cellular uptake of RNA therapeutics.
• Platforms like lipid-based nanoparticles, polymeric systems, and hybrid nanocarriers show efficacy in various applications.
• Multifunctional nanocarriers capable of co-delivering chemotherapy and genes present a promising strategy for enhanced cancer treatment.

Conclusions:

• Novel nanocarrier technologies are crucial for addressing the delivery challenges associated with RNA-based gene therapies.
• Continued research into nanocarrier design and functionality will pave the way for more effective treatments for genetic disorders and cancer.
