Marine anticancer drugs in modulating miRNAs and antioxidant signaling

Area of Science:

• Marine pharmacology and cancer therapeutics.
• Molecular biology, focusing on microRNAs (miRNAs) and oxidative stress.
• Bioinformatics and drug target identification.

Background:

• Marine-derived compounds are recognized for their anticancer properties, often mediated by inducing oxidative stress in cancer cells.
• The balance of redox homeostasis is crucial; imbalanced states, particularly downregulated antioxidant signaling, promote oxidative stress and cancer cell death.
• Marine drugs are known to modulate miRNA expression, but their specific roles in targeting antioxidant pathways remain underexplored.

Purpose of the Study:

• To systematically review and categorize marine drugs that modulate miRNAs to downregulate antioxidant targets, thereby inducing anticancer oxidative stress.
• To identify miRNAs that are downregulated by marine drugs for antioxidant protection in non-cancer cells.
• To delineate the network connecting marine drugs, their modulated miRNAs, and their antioxidant targets for potential therapeutic applications.

Main Methods:

• Literature review focusing on marine drugs, miRNAs, and oxidative stress in cancer.
• Categorization of marine-drug-modulated miRNAs based on their effect on antioxidant targets (downregulation for anticancer, upregulation for protection).
• Utilized the bioinformatics tool miRDB to predict and summarize putative antioxidant targets of miRNA-modulating marine drugs.

Main Results:

• Identified and categorized marine drugs that influence miRNA expression to modulate antioxidant pathways.
• Compiled a list of potential antioxidant targets affected by marine-drug-mediated miRNA regulation.
• Established a framework for understanding the intricate relationships between marine drugs, miRNAs, and antioxidant mechanisms.

Conclusions:

• Marine drugs offer a promising avenue for anticancer therapy by manipulating miRNA-controlled antioxidant signaling pathways.
• The identified networks provide a precise basis for exploring novel marine-derived anticancer agents and understanding their cytoprotective effects.
• Further research into these specific drug-miRNA-target interactions can accelerate the development of targeted marine-based cancer treatments.
