Single cell transcriptomic landscape of adult and pediatric non-ischemic cardiomyopathy

J Mol Cell Cardiol. 2026 Feb:211:98-108. doi: 10.1016/j.yjmcc.2025.12.002. Epub 2025 Dec 4.

Abstract

Non-ischemic cardiomyopathy (NICM) is a devastating diagnosis with a wide array of phenotypes, ranging from mild cardiac hypertrophy to end-stage heart failure. Single-cell/nucleus RNA sequencing technologies have expanded and become a necessary tool to unravel the transcriptome across thousands to millions of cells. Studies incorporating these technologies to examine pediatric and adult myocardium have improved our understanding of underlying pathophysiology in cardiomyopathy, identified novel gene and genetic pathway associations, and paved the way for precision medicine therapeutics in cardiovascular medicine. We compiled the recent literature that showcase single cell/nucleus technologies in NICM in adult and pediatric populations and describe cell type-specific changes, ultimately setting the stage for future targeted gene manipulation/precision medicine.

Keywords: Gene expression; Non-ischemic cardiomyopathy; Pediatrics; Single cell/nuclei RNA sequencing.
