This study investigated the effects of Cadmium (Cd) on quail kidney injury and the protective effect of Honokiol (HKL) on Cd-induced nephrotoxicity. The results showed that Cd caused significant changes in growth performance, kidney histopathology, antioxidant enzymes, and other parameters, while HKL treatment alleviated oxidative stress and improved kidney function.
Japanese quail is a highly economically valuable bird due to its commercial production for meat and eggs. Although studies have reported Cadmium (Cd) is a ubiquitous heavy metal that can cause injury to various organs, the molecular mechanisms of Cd on quail kidney injury remain largely unknown. It has been reported that Honokiol (HKL), a highly functional antioxidant, can protect cells against oxidative stress effectively. This study was conducted to investigate the effects of Cd on quail kidneys injury and the protective effect of HKL on Cd-induced nephrotoxicity. A total of 40 Japanese quails were randomly divided into four groups: the control group, Cd treatment group, Co-treatment group and HKL treatment group. The results showed that Cd resulted in significant changes in growth performance, kidney histopathology and kidney biochemical status, antioxidant enzymes and oxidative stress parameters, and ultrastructure of renal tubular epithelial cells, compared with controls. Cd increased the expression of autophagy-related and apoptosis-related genes, but decreased expression of lysosomal function-related and UPRmt-related genes. The co-treatment group ameliorated Cd-induced nephrotoxicity by alleviating oxidative stress, inhibiting apoptosis, repairing autophagy dysfunction and UPRmt disorder. In conclusion, dietary supplementation of HKL showed beneficial effects on Japanese quail kidney injury caused by Cd.
