Current Progress and Future Outlook for Synthetic Gene Circuits in Cardiovascular Therapy

Area of Science:

• Synthetic biology
• Cardiovascular medicine
• Genetic engineering

Background:

• Cardiovascular diseases (CVDs) are a leading cause of mortality globally.
• Current pharmacotherapies for CVDs are often systemic and lack precision.
• There is a critical need for novel therapeutic strategies with improved spatiotemporal control.

Purpose of the Study:

• To review the progress of synthetic gene circuits in cardiovascular therapy.
• To explore applications in direct cardiac treatment and indirect risk factor management.
• To discuss future directions, including computational tools and translational frameworks.

Main Methods:

• Review of current literature on synthetic gene circuits for cardiovascular applications.
• Categorization of circuits based on clinical relevance: direct cardiac, indirect risk factor management, and orthogonal architectures.
• Discussion of computational tools and a proposed Design-Build-Test-Learn framework.

Main Results:

• Synthetic gene circuits demonstrate potential for precise cardiovascular interventions.
• Applications range from inducible switches and classifier systems to managing cholesterol and inflammation.
• Emerging computational tools and frameworks aim to accelerate therapeutic development.

Conclusions:

• Synthetic biology offers a programmable and precise therapeutic paradigm for cardiovascular diseases.
• Engineered gene circuits can target cardiac pathologies and upstream risk factors.
• A modified Design-Build-Test-Learn framework is proposed to facilitate the translation of these next-generation cardiac therapeutics.
