Nrf2 as a Potential Mediator of Cardiovascular Risk in Metabolic Diseases

Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that elucidates the role of Nrf2 activation in specific tissues, such as adipose tissue, liver, pancreas and others, is important for better understanding of the multiple roles of Nrf2. Additional studies may also provide new redox balance-targeted therapy for the treatment of metabolic diseases and consequent mitigation of cardiovascular risk. FIGURE 1 Figure 1. Mechanisms involved in the actions of reactive oxygen species that lead to metabolic diseases and cardiovascular risk development. Metabolic diseases are closely associated with increased generation of reactive oxygen species (ROS) due to reduced Nrf2 antioxidant activity. This phenomenon culminates in target-organ damage and metabolism disorders, such as adipogenesis and adipose tissue inflammation, increased production of hepatic cholesterol, decreased insulin secretion, insulin resistance, los...
