Serum gamma-glutamyltransferase level is associated with serum superoxide dismutase activity and metabolic syndrome in a Japanese population

摘要

Background Serum gamma-glutamyltransferase level has attracted considerable attention as a predictor of various conditions, such as cardiovascular disease and cancer. Although the mechanism that links the serum gamma-glutamyltransferase level to these diseases is not fully understood, one explanation is that gamma-glutamyltransferase may be closely related to oxidative stress. We conducted a large cross-sectional study to evaluate the relationship between serum gamma-glutamyltransferase and oxidative stress.
