Mitigation Potential of Zingerone and Rutin on Toxicity Mechanisms of Nickel To Zebrafish Based on Morphological, Dna Damage and Apoptosis Outcome Analysis

Abstract

Although nickel (Ni) is an important cofactor for various enzymes in biological systems, it can cause serious problems when insufficient or excessive in an organism. Therefore, it is very important to investigate Ni in biological systems, especially in cells with its related pathogenic mechanism. This study was carried out to demonstrate the effects of zingerone (ZO) and rutin (RN) administration against nickel chloride (NiCl2) toxicity on neurobehavioral performance and brain oxidative status in zebrafish (Danio rerio) embryos/larvae on histological perspective. The experimental design of the study, which included twenty groups of fish, each containing 10 embryos, was prepared as semi-static and the trial continued for 96 hpf. In the obtained findings, it was determined that ZO and RN had a mitigating effect in this toxicity table where Ni caused oxidative stress in zebrafish larvae, induced DNA damage and apoptosis. A similar picture is valid for malformation processes as well as survival and hatching rates. These results showed that nickel is toxic to developing embryos via acting different mechanisms. In conclusion, we observed that ZO and RN have a greater effect on physiology, DNA damage and apoptosis than gross morphology, with a significant ameliorative effect.
