| Fecha: | 2025 |
| Resumen: | Background: Vascular smooth muscle cells loaded with cholesterol (foam-VSMCs) play a crucial role in the progression of human atherosclerosis. Exchange Protein Directly Activated by cAMP 1 (EPAC1) is a critical protein in the regulation of vascular tone, endothelial function, and inflammation. Our objectives were to identify proteins specifically secreted by foam human coronary VSMCs (foam-hcVSMC) to evaluate their potential as circulating biomarkers for diagnosing coronary artery disease (CAD), and to ascertain the mechanisms underlying their levels in the blood of patients with CAD. Methods and Results: Differential proteomics identified EPAC1 as a differential foamhcVSMC-secreted protein. Circulating EPAC1 levels were measured by ELISA in blood from 202 patients with suspected CAD who underwent coronary computed tomography angiography (CCTA). Blood EPAC1 levels were significantly lower in CAD patients compared to controls (p < 0. 001). EPAC1 levels were reduced in both men and women with severe CAD (SIS. |
