Resveratrol acts as an antioxidant in leukocytes of patients with diabetes mellitus 2 through the AMPK signaling pathway

Abstract

Diabetes is characterized by disturbances in serum glucose levels caused by insulin resistance, with consequent high blood glucose levels. Permanently increased blood glucose tends to lead to an increase in reactive oxygen species (ROS). Therefore, one of the mechanisms to contain this process is to consider antioxidant treatment. Within this context, resveratrol (RSV) stands out. Among the pathways of action of this compound, AMPK plays a fundamental role in regulating its antioxidant activity. The objective of the work aims to verify the antioxidant profile of RSV, through the AMPK pathway, in leukocytes of patients with type 2 diabetes mellitus (DM2) between 60 and 80 years old. 12 individuals were selected, divided into two groups: control group (n=6) and experimental group (n=6). After blood collection and leukocyte separation, the luminol-dependent chemiluminescence assay was performed. To analyze the involvement of the AMPK pathway, the inhibitor compound C was used. The result obtained showed that there was an antioxidant behavior of AMPK in cells stimulated with peroxide and treated with RSV, this in turn decreased the production of ROS in leukocytes of all samples, but this effect was less significant in DM2 patients. This oxidation, which is more pronounced in diabetics, can lead to target organ damage. As RSV played an important role in reducing ROS, we concluded that it is an important compound in preventing target organ damage in patients with this comorbidity, acting through the AMPK pathway.
