Beyond a Simple Switch: Decoding the Multifactorial Phenotypic Plasticity of Vascular Smooth Muscle Cells

Area of Science:

• Cardiovascular Biology
• Cellular Mechanisms
• Molecular Biology

Background:

• Vascular smooth muscle cells (VSMCs) are key regulators of vascular homeostasis and cardiovascular diseases (CVDs) due to their adaptable phenotype.
• VSMC phenotypic plasticity is a complex process influenced by multiple biological layers.

Discussion:

• This special issue examines recent findings on the molecular, epigenetic, metabolic, and mechanical regulators of VSMC behavior.
• Key areas include RNA modifications, chromatin remodeling, lipid metabolism, and mechanotransduction in VSMC phenotypic switching.

Key Insights:

• Understanding VSMC plasticity is vital for both vascular repair and understanding disease pathogenesis.
• Advances highlight novel therapeutic targets and diagnostic strategies for CVDs.

Outlook:

• Future research will further elucidate the multifactorial control of VSMC plasticity.
• Translational studies will focus on leveraging these insights for clinical applications in cardiovascular medicine.
