The presence of apoptotic cells in atherosclerotic lesions has been broadly reported in the past ten years. The majority of these apoptotic cells are macrophages. However, the pathogenic role of macrophage apoptosis in the development of atherosclerosis remains to be elucidated. Elevated expression of Bax, one of the pivotal pro-apoptotic proteins of the Bcl-2 family, has been found in human atherosclerotic plaques. Activation of Bax also occurs in free cholesterol-loaded and oxysterol treated mouse macrophages. In this study, we evaluated the influence of Bax deficiency on apoptosis in macrophage-like P388D1 cells by using small interfering RNA (siRNA) to suppress Bax …
