CircRNAs in Pancreatic Cancer: New Tools for Target Identification and Therapeutic Intervention

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Pancreatic cancer remains a significant health challenge with limited effective treatments.
• Circular RNAs (circRNAs) are emerging as critical regulators in various cancers, including pancreatic cancer.
• Understanding the role of circRNAs in pancreatic cancer pathogenesis is crucial for developing novel therapeutic strategies.

Purpose of the Study:

• To review and identify circular RNAs (circRNAs) with demonstrated efficacy in preclinical pancreatic cancer models.
• To explore the therapeutic potential of circRNAs by analyzing their targeted mechanisms.
• To evaluate existing and potential therapeutic interventions targeting circRNAs in pancreatic cancer.

Main Methods:

• Literature review of preclinical in vivo studies on circRNAs in pancreatic cancer.
• Categorization of identified circRNAs based on their targeted biological mechanisms.
• Analysis of therapeutic strategies for modulating circRNA expression and function.

Main Results:

• A comprehensive list of circRNAs targeting chemoresistance, secreted proteins, transcription factors, signaling pathways, ubiquitination, and autophagy was identified.
• Identified circRNAs represent potential therapeutic targets for pancreatic cancer intervention.
• Various therapeutic modalities, including antisense oligonucleotides (ASO), siRNAs, shRNAs, CRISPR-CAS, and replacement therapies, were examined for their efficacy.

Conclusions:

• Circular RNAs (circRNAs) are promising therapeutic targets and agents for pancreatic cancer.
• Modulating circRNA expression through inhibition or replacement offers potential treatment avenues.
• Further research into target validation and delivery systems is essential for clinical translation.
