Bottleneck limitations for microRNA-based therapeutics from bench to the bedside

Area of Science:

• Molecular Biology
• Genetics
• Pharmacology

Background:

• MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression.
• Extensive research links miRNAs to various diseases, including cancer and cardiovascular conditions.
• The therapeutic potential of miRNAs is rapidly expanding.

Purpose of the Study:

• To review the obstacles hindering the clinical translation of microRNA-based therapeutics.
• To identify key challenges in basic research and clinical application of miRNA drugs.

Main Methods:

• Literature review focusing on microRNA research and therapeutic development.
• Analysis of barriers in preclinical and clinical stages of miRNA drug development.

Main Results:

• Significant advances in understanding miRNA roles in disease.
• Identification of critical challenges: vector delivery, off-target effects, toxicity, immunogenicity, and dosage.
• Stringent criteria and financial risks impede therapeutic progression.

Conclusions:

• MicroRNA therapeutics face substantial bench-to-bedside obstacles.
• Addressing issues in delivery, safety, and efficacy is essential for clinical success.
• Overcoming these barriers is vital for realizing the full potential of miRNA-based drugs.
