Summary
This study explores the transcriptomic landscape of human coronary artery smooth muscle cells (HCASMCs) in response to stimuli that promote differentiation (Repsox) or dedifferentiation (PDGF-BB, IL-1b). Our RNA sequencing analysis identifies DNA damage-inducible transcript 4 (DDIT4) as a key regulator of vascular smooth muscle cell (VSMC) phenotypic switching, showing its significant upregulation in synthetic phenotypes and downregulation in contractile phenotypes. This dataset provides a resource for understanding the transcriptional programs governing VSMC plasticity in the context of vascular remodeling and atherosclerotic disease.
