Abstract: | AbstractSeveral studies have shown the role of thiol-rich proteins especially metallothionein (MT) in the therapeutic interventions against oxidative damage. Previously, we have provided strong evidence for the involvement of ROS in iron nitrilotriacetate (Fe-NTA)-induced renal toxicity, which may have relevance to its carcinogenicity. The purpose of this study was to evaluate the role of zinc metallothionein (Zn-MT) on the protection against Fe-NTA-induced renal oxidative damage. The results demonstrate that Zn-MT pretreatment provided protection against Fe-NTA-induced mortality in mice (40% protection). Similarly, Zn-MT pretreatment also provided protection against Fe-NTA-induced lipid peroxidation (26% inhibition, P < 0.001). It is proposed that Zn-MT protects kidney tissue against the noxious effect of Fe-NTA primarily by interference with lipid peroxides. It is concluded that Zn-MT may serve as an excellent physiological antioxidant against Fe-NTA-mediated renal oxidative damage. |
