Summary

This chapter discusses oxidative stress in adipose tissue and its involvement in several features of metabolic syndrome. Adipocytes produce various kinds of biologically active substances, which are conceptualized as adipocytokines/adipokines. In 3T3L1 adipocytes, TNFα and glucocorticoid facilitate reactive oxygen species (ROS) generation, and treatment with an anti-oxidative agent, MnTBAP, or with anti-oxidative enzymes such as superoxide dismutase (SOD) or catalase, can improve insulin resistance. Oxidative stress in the brain is involved in the pathogenesis of obesity-associated hypertension. Reduction of oxidative stress by angiotensin II receptor blockers (ARBs) may provide additional beneficial effects for the cardiovascular system beyond blood pressure, especially among patients with hypertension associated with metabolic syndrome. To date, lifestyle changes, such as improving overnutrition, comprise the most important clinical strategy to reduce oxidative stress and prevent many of the features of metabolic syndrome, as well as the development of cardiovascular diseases.
