    Alterações no perfil proteico do ventrículo esquerdo de ratos após tratamento com óleo de soja: um estudo proteômico

    Several studies show that consumption of vegetable oils, such as soybean oil, rich in polyunsaturated fatty acids (PUFAs) has beneficial health effects by preventing or reducing the risk factors of cardiovascular diseases. While the demonstration of the beneficial effects of the consumption of unsaturated fatty acids on the cardiovascular system has been proven in macroscopic level, the molecular/cellular mechanisms responsible for this phenomenon are poorly understood. In this work a comparative proteomic approach, two-dimensional gel electrophoresis (2D) coupled to mass spectrometry (MALDI-TOF / TOF) was applied to investigate the rats heart proteome differences (left ventricle - LV) that not received (control group - CT) and received 0.1mL of soybean oil intramuscularly for 15 days (treated group - TR). Soybean oil treatment induced improvement in left ventricular function, and a significant change in LV proteome in the TR animals. The TR animals present a lower value of LVEDP. The protein profile of VE revealed differences in the expression of 60 protein spots (p<0.05) between CT and TR groups, 14 of these were identified by MS and MS / MS, being 12 non-redundant proteins. Robust changes were detected in proteins involved in muscular contraction, structural and antioxidant system. The TR group presented an increase in intensity of proteins involved in muscle contraction (myosin light chain 3-(3-MCL), creatine kinase M (CKM)) and tireodoxina antioxidant enzyme. Low intensity cytoskeletal protein, desmin, was detected. The differences in the intensity levels of these spots-related proteins in TR group, might be linked to improvement in left ventricular function.
