β2-Glycoprotein I (β2-GPI) is a plasma glycoprotein primarily synthesized in the liver. The interindividual variability of β2-GPI expression in subjects with various metabolic syndromes and disease states suggests that it may have clinical importance. However, the regulation of β2-GPI gene expression has not been clarified. To gain more insight into the control of β2-GPI gene expression, we clo...
