    Tissue proteomics in atherosclerosis: elucidating the molecular mechanisms of cardiovascular diseases
    (Expert Review of Proteomics, 2009) Cuesta, Fernando de la; Álvarez Llamas, Gloria; Gil Dones, Félix; Martin-Rojas, Tatiana; Zubiri, Irene; Pastor Vargas, Carlos; Barderas, Maria ; Vivanco Martínez, Fernando
    Atherosclerosis is a disease with higher levels of mortality in developed countries. Comprehension of the molecular mechanisms can yield very useful information in clinics for prevention, diagnosis and recovery monitoring. Proteomics represents an ideal methodology for this purpose, as proteins constitute the effectors of the different biological processes running during pathogenesis. To date, studies in atherosclerosis have been mainly focused on the search for plasma biomarkers. However, tissue proteomics allows going deeper into tissue secretomes, arterial layers or particular cells of interest, which, in turn, constitutes a more direct approximation to in vivo operating mechanisms. The aim of this review is to report latest advances in tissue proteomics in atherosclerosis and related diseases (e.g., aortic stenosis and ischemic injury).

    Secretome analysis of atherosclerotic and non-atherosclerotic arteries reveals dynamic extracellular remodeling during pathogenesis
    (Journal of Proteome, 2012) Cuesta, Fernando de la; Barderas, Maria G.; Calvo, Enrique; Zubiri, Irene; Maroto, Aroa S.; Darde, Veronica M.; Martin-Rojas, Tatiana; Gil Dones, Félix; Posada-Ayala, Maria; Tejerina, Teresa; Lopez, Juan A.; Vivanco Martínez, Fernando; Álvarez Llamas, Gloria
    Aims: Early detection of cardiovascular diseases and knowledge of underlying mechanisms is essential. Tissue secretome studies resemble more closely to the in vivo situation, showing a much narrower protein concentrations dynamic range than plasma. This study was aimed to the analysis of human arterial tissue secretome and to the quantitative comparison of healthy and atherosclerotic secretome to discover proteins with key roles in atherosclerosis development. Methods and results: Secretomes from three biological replicates of human atherosclerotic coronary arteries (APC), preatherosclerotic coronaries (PC) and mammaries (M) were analyzed by LC-MS/MS. The identified proteins were submitted to Ingenuity Pathway Analysis (IPA) tool. Label-free MS/MS based quantification was performed and validated by immunohistochemistry. 64 proteins were identified in the 3 replicates of at least one of the 3 groups and 15 secreted proteins have not been previously reported in plasma. Four proteins were significantly released in higher amounts by mammary tissue: gelsolin, vinculin, lamin A/C and phosphoglucomutase 5. Conclusion: The study of tissue secretome reveals key proteins involved in atherosclerosis which have not been previously reported in plasma. Novel proteins are here highlighted which could be potential therapeutic targets in clinical practice. This article is part of a Special Issue entitled: Proteomics: The clinical link.
