Mac-2 binding protein (M2BP) plays an important role in cell adhesion. In a recent cross-sectional study we reported that serum M2BP concentrations may reflect silent atherosclerosis. The aim of the present prospective follow-up study was to investigate possible relationships between changes in concentrations of M2BP and other factors over a >3-year period. The present study enrolled subjects who visited Enshu hospital from 2014 to 2015 for a periodic physical check-up and then attended for another physical check-up after >3 years (n = 174). Factors affecting changes in M2BP concentrations were investigated at both baseline and follow-up. Subjects with liver dysfunction, a history of hepatic disease, malignant neoplasm, or cardiovascular events at baseline were excluded. Univariate and multivariate regression analyses showed that changes in serum M2BP concentrations during the follow-up period were significantly associated with changes in low-density lipoprotein cholesterol (LDL-C), triglyceride, and oxidative stress marker derivatives of reactive oxygen metabolites (d-ROM) concentrations. Moreover, the increase in LDL-C was significantly greater in subjects in whom M2BP concentrations increased during the follow-up period. Logistic regression analysis with an endpoint of increased M2BP revealed that increased LDL-C was an independent determinant of an increase in M2BP during the follow-up period. During the observation period of >3 years, serum M2BP concentrations were increased in subjects who also exhibited increases in levels of metabolic parameters, especially LDL-C, and the oxidative stress marker d-ROM. These results support that serum M2BP reflects one of the contributors to the progression of silent atherosclerosis.
