Molybdenum Induces Mitochondrial Oxidative Damage in Kidney of Goats
Abstract The purpose of this study was to evaluate the effects of excessive molybdenum (Mo) on renal function and oxidative stress in goats. Twenty-seven healthy goats were randomly allotted in three groups and were fed deionized water to which sodium molybdate [($ NH_{4} $)6$ Mo_{7} $$ O_{24} $·$ 4H_{2} $O] was added at different doses of 0, 15, and 45 mg Mo/(kg·BW) for 50 days, respectively. The results indicated that white blood cell (WBC) counts were significantly increased (P < 0.05), while red blood cell (RBC) counts, hemoglobin (HGB), and mean corpuscular hemoglobin concentration (MCH) were tended to decrease with the increasing of the experimental period in high-Mo group compared with the control group. Besides, blood urea nitrogen (BUN) and creatinine (CREA) contents in serum were increased (P < 0.05) in both groups supplemented with molybdenum. Meanwhile, contents of copper (Cu) from the both experimental groups were significantly decreased (P < 0.05), while contents of zinc (Zn) and iron (Fe) were increased (P < 0.05) in serum. The contents of Cu were significantly increased (P < 0.05), while the contents of zinc (Zn) and iron (Fe) did not obviously change (P > 0.05) in the kidney. In addition, the activities of total antioxidant capacity (T-AOC), superoxide dismutase (SOD), and catalase (CAT) significantly decreased (P < 0.05) in the mitochondria, whereas malondialdehyde (MDA) and nitric oxide synthase (NOS) expression significantly increased (P < 0.05). Collectively, these results indicated that excess Mo exposure could induce secondary Cu deficiency and oxidative stress in the kidney, which finally undermine the renal function of goats..
