Identification of non-cardiomyocytes marker genes in patients with diabetes and cardiomyopathy through single-cell analysis

Peer-reviewed research using single-cell RNA sequencing to identify specific cell types and gene markers (particularly PTPRC) involved in diabetic cardiomyopathy. The study identified eight distinct cell types, mapped metabolic pathways, and validated PTPRC's role in endothelial cell function through multiple experimental assays (CCK-8, colony formation, migration/invasion assays). This provides concrete molecular targets for therapeutic development.

This is foundational research identifying markers and pathways, not a treatment or cure. PTPRC's role was demonstrated in cell culture (HUVECs), not yet in human patients. Therapeutic translation remains years away. Does not prove clinical efficacy or that targeting these pathways will successfully treat DCM.
