Exploring the therapeutic potential of microRNAs: targeted gene regulation strategies for enhanced cancer therapy

Area of Science:

• Biochemistry
• Molecular Biology
• Oncology

Background:

• Cancer poses a significant global health challenge, with conventional treatments facing limitations like drug resistance and toxicity.
• MicroRNAs (miRNAs) are key regulators of gene expression involved in crucial cellular processes relevant to cancer.
• miRNAs exhibit a dual role in cancer, acting as either tumor suppressors or oncogenes, highlighting their therapeutic potential.

Purpose of the Study:

• To review the therapeutic potential of microRNAs (miRNAs) in cancer treatment.
• To explore strategies for modulating cancer pathways and overcoming drug resistance using miRNAs.
• To discuss advanced delivery systems and challenges associated with miRNA-based cancer therapies.

Main Methods:

• Literature review of studies on microRNA (miRNA) function in cancer.
• Analysis of miRNA mimics and antagomiRs for gene expression restoration.
• Examination of nanoparticle and exosome-based delivery systems for miRNA therapeutics.
• Discussion of challenges including miRNA degradation, off-target effects, and immunogenicity.

Main Results:

• MicroRNAs (miRNAs) can modulate key cancer pathways, offering a new therapeutic avenue.
• miRNA mimics and antagomiRs show promise in restoring normal gene expression.
• Nanoparticles and exosomes provide effective, targeted delivery of miRNA therapeutics.
• Challenges like degradation and off-target effects need to be addressed for clinical translation.

Conclusions:

• MicroRNA-based therapies hold significant promise for enhancing cancer treatment efficacy.
• Integration with existing therapies can improve outcomes and enable personalized cancer management.
• Further research into delivery systems and overcoming challenges is crucial for clinical application.
