| Research Abstract |
The processes of arteriosclerosis are affected by interactions among numerous biological pathways, such as responses to inflammation, oxidative stress and endoplasmic reticulum (ER)stress. C/EBP homologous protein (CHOP), which is well known to induce cellular apoptosis in response to severe ER stress, is reportedly up-regulated in plaque lesions. Cuff injury-induced neointimal formation and hypercholesterolemia-induced aortic plaque formation were markedly inhibited in CHOP-/-mice with suppressed aortic expressions of inflammatory factors and oxidative stress markers. CHOP may play important roles in augmenting potentially pathological biological stress responses and contribute to the progression of vascular remodeling and atherosclerosis.
