This study analyzed the expression of extracellular matrix (ECM) proteins during aortic valve calcification with mass spectrometry, and further validated in an independent human cohort using RNAseq data. The study reveals that valve calcification is associated with significant disruption in ECM and metabolic pathways, and highlights a strong connection between metabolic markers and ECM remodeling. It also identifies FNDC1 and MXRA5 as novel ECM biomarkers in calcified valves, electing them as potential targets in the development and progression of aortic stenosis.
本研究采用质谱分析法分析了主动脉瓣钙化过程中细胞外基质(ECM)蛋白的表达情况,并利用RNA测序数据在一个独立的人类队列中进行了进一步验证。该研究表明,瓣膜钙化与ECM和代谢途径的显著破坏有关,并突出了代谢标志物与ECM重塑之间的紧密联系。研究还将FNDC1和MXRA5鉴定为钙化瓣膜中新的ECM生物标志物,使其成为主动脉瓣狭窄发生和发展的潜在靶点。
