Quantitative proteomics identifies clusterin as a novel biomarker for atherosclerosis

Animal Models and Experimental Medicine, EarlyView.
This schematic illustrates the proposed mechanism. In advanced atherosclerotic lesions, upregulated CLU on the cell surface activates low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1). This interaction triggers the phosphorylation and activation of AKT.
