Transgenic animals

Abstract

Molecular biological technique has enabled us to create numerous transgenic animals characterized by enhanced or reduced expression of target gene products. These animal models are very useful not only to study the physiological roles of target gene products but also to evaluate the clinical usefulness of newly developed drugs and other therapeutic measures. Unfortunately, we still do not have a genetically engineered animal model that spontaneously develops acute coronary syndrome. However, there are several transgenic mice showing abnormal lipid metabolism and developing premature atherosclerosis. In this chapter, recent advance in the field of atherosclerotic animal models will be summarized.
