Effect of gold nanoparticles (Au-NPs) biosynthesized by N. oculata algal extract against the changes induced by lithium carbonate (Li2CO3) in levels of mRNA expression of antioxidants enzymes (SOD1, CAT, and GPx1) in (a) kidney and (b) brain in rats. Data were calculated from five replicates and expressed as mean ± SE, (a) significant versus control group, (b) significant versus toxic (Li2CO3) group at p ≤ 0.05.
