Furthermore, Živančević et al. explored the role of oxidative stress, particularly involving SOD2, in neurodegeneration induced by toxic metal mixtures (Pb, methylmercury, Cd, and As), offering new insights into shared molecular mechanisms underlying amyotrophic lateral sclerosis (ALS), Parkinson’s disease (PD), and Alzheimer’s disease (AD) [34]. The gene discussed is SOD2; the disease is Alzheimer disease.
