The present study investigates the role of paraoxonase 2 (PON2) in the attenuation of macrophage triglycerides (TG) biosynthesis, and oxidative stress, under diabetic conditions.Peritoneal macrophages (MPM) from PON2-deficient and from C57BL/6 control mice were harvested and cultured under normal (5mM) or high glucose concentration (30mM), and evaluated for cellular TG metabolism as well as for their...
Paraoxonase 1 (PON1) is a lipo-lactonase which is associated with HDL and possesses antioxidative properties. Diabetes is characterized by increased oxidative stress and by decreased PON1 activity. We aimed to analyze whether oxidative status and PON1 levels in mouse sera and macrophages could affect streptozotocin (STZ)-induced diabetes development. We have used two models of mice under low oxidative...
