Peripheral artery disease (PAD) often advances to chronic limb-threatening ischemia (CLTI), resulting in severe complications such as limb amputation. Despite the potential of therapeutic angiogenesis, the mechanisms of cell-cell communication and transcriptional changes driving PAD are not fully understood. Profiling long noncoding RNAs (lncRNAs) from gastrocnemius muscles of participants with or without CLTI revealed that a vascular smooth muscle cell–enriched (SMC-enriched) lncRNA, CARMN...
