Azoxystrobin (AZ) is a broad-spectrum systemic fungicide that widely used in the world. The present study investigated the toxicity effects on zebrafish after short-term exposure of AZ. Results demonstrated that the larval stage was most susceptible to AZ in the multiple life stages of zebrafish, with 96 h-LC value of 0.777 mg/L. Zebrafish larvae were exposed to different AZ concentrations (0, 0.1, 1, 10, 100 μg/L) and examined on 24, 48 and 72 h. It was found that AZ induced ROS accumulation, increased GST, GPX and POD activity and the transcriptions of antioxidant and stress response related genes, while the opposite trend occurred for SOD and CAT activity in 24-h or 48-h exposure period. The increased E and VTG levels in zebrafish larvae, and altered transcription levels of regulatory and steroidogenic genes in the hypothalamus-pituitary-gonad (HPG) axis indicated the endocrine disruption capacity of AZ. The transcripts of mdm2, p53, ogg1, bcl2, bbc3, cas8 and cas9 involved in cell apoptosis, and the mRNA levels of cytokines and chemokines such as cxcl-c1c, ccl, il-1β, il-8, ifn, and tnfα were in accordance with the trends of the examined genes involved in oxidative stress and endocrine system. The results suggested that short-term exposure to AZ might impose ecotoxicological effects on zebrafish larvae, and the information presented here also provide molecular strategies and increase mechanistic understanding of AZ-induced toxic response, and help elucidate the environmental risks of AZ.
