RESUMEN
Vascular smooth muscle cells (VSMCs) are crucial components of the arterial wall, controlling blood flow and pressure by contracting and relaxing the artery walls. VSMCs can switch from a contractile to a synthetic state, leading to increased proliferation and migratory potential. Epigenetic pathways, including DNA methylation, play a crucial role in regulating VSMC differentiation and phenotypic flexibility. DNA methylation involves attaching a methyl group to the 5' carbon of a cytosine base, which regulates gene expression by interacting with transcription factors. Understanding the key factors influencing VSMC plasticity may help to identify new target molecules for the development of innovative drugs to treat various vascular diseases. This review focuses on DNA methylation pathways in VSMCs, summarizing mechanisms involved in controlling vascular remodeling, which can significantly enhance our understanding of related mechanisms and provide promising therapeutic approaches for complex and multifactorial diseases.
