The results of the correlation analysis revealed relationships between proapoptotic markers and the levels of proliferation and migration of smooth muscle cells of the vascular wall, namely, Bax and PDGF BB (r=-0.646, p=0.023); p53 and PDGF BB (r=-0.626, p= 0.03); and sFas and PDGF BB (r=-0.828, p <0.01) in samples with progression of atherosclerosis in G A1patients. The gene discussed is BAX; the disease is atherosclerosis.
