On the other hand, in T2DM, there is a marked meta-inflammation and oxidative stress, which has been related to decreased expression and activity of cytoplasmic (Zn, Cu-SOD: SOD1), mitochondrial (Mn-SOD: SOD2), and extracellular (Cu-SOD: SOD3) superoxide dismutase (SOD) enzyme, an effect observed in different tissues such as liver, skeletal muscle or kidney of diabetic animal models [17,21,22,23,24]. Here, SOD3 is linked to type 2 diabetes mellitus.
