Exosomal STAT1 derived from high phosphorus‑stimulated vascular endothelial cells induces vascular smooth muscle cell calcification via the Wnt/β‑catenin signaling pathway.

ABSTRACT: Vascular calcification is commonly observed in chronic kidney disease. The mechanism of how the calcification signal from endothelial cells is transmitted to vascular smooth muscle cells (VSMCs) remains unknown. The aim of the present study was to investigate whether exosomes from HUVECs (HUVEC‑Exos) could regulate VSMC calcification and its potential signaling pathway. HUVEC‑Exos were isolated from HUVECs under no phosphorus (NP) and high phosphorus (HP) conditions. Alizarin Red S staining and calcium (Ca) content analysis were carried out to detect calcification in VSMCs. Proteomics analysis was carried out to detect the differential expression of exosomal proteins. Protein and mRNA levels were measured by western blot analysis and reverse transcription‑quantitative PCR (RT‑qPCR). Exosom
