Abstract

Introduction Analysis of the complex structure of the atheroma plaque is a classical object of cardiovascular research. We studied proteins secreted by the vascular wall, which could be potential plasma markers. Statins or calcium channel blockers modulate the levels of different circulating proteins in patients with diverse cardiovascular diseases. Methods Two-dimensional electrophoresis and mass spectrometry were applied to identify and characterize proteins differentially secreted by atheroma plaque samples incubated ex vivo versus adjacent fibrous segments considered as controls. We also analyzed the modulatory effect of atorvastatin (10-5 M), amlodipine (10-6 M) and the combination of both drugs. Results From an average of 620 proteins detected per gel, a total of 83 proteins secreted by atheroma plaque samples were identified by mass spectrometry: 34 proteins were increased in atheroma plaque supernatants versus control segments while 31 showed decreased secretion levels in atheroma plaques. Different effects were detected after in vitro drug administration to complicated atheroma plaques, depending on the kind of drug and protein considered, although the majority of the proteins identified reverted to normal levels independently of the treatment administered. Conclusion Proteomic analysis characterized a significant number of novel proteins potentially involved in the formation and instability of complicated atherosclerotic plaques. Modulation of these markers by different drugs may help us to understand new potential mechanisms through which these drugs exert their beneficial effects on atherothrombosis.
