摘要: Ammonia is one of the most serious environmental stressors which severely affect fishery production. Ammonia toxicity to fish has a tight relationship with oxidative stress, inflammation and ferroptosis (a type of programmed cell death characterized by iron-dependent lipid peroxidation), but the temporal response of the above three in brain remains unclear. In the present study, yellow catfish were exposed to three concentrations of ammonia: low concentration (TA-N < 0.01 mg L-1, LA), middle concentration (TA-N 5.70 mg L-1, MA), high concentration (TA-N 28.50 mg L-1, HA) for 96 h. Brain was selected as target tissues for analysis. Results showed that ammonia stress resulted in firstly increased contents of hydroxyl radical at 1 h, total iron at 12 h, malondialdehyde at 48 h, respectively, and decreased contents of GSH at 3 h. The initial high expression levels of ferroptosis (GPX4, system xc- , TFR1) and inflammatory-related factors (NF-ƙB p65, TNF, COX-2, and LOX-15B), antioxidant enzymes genes (SOD and CAT) were observed at first hour upon MA or HA stress. Combining all, it suggested that brain fer-roptosis and inflammation were the first to be activated at the initial stage of ammonia stress, and then that provoked oxidative stress.
