Fumonisins (Fums) are types of mycotoxin that widely contaminante feed material crops, and can trigger potential biological toxicities to humans and various animals. However, the toxicity of Fums on porcine blood vessels has not been fully explored. Fumonisin B1 (FB1) is the main component of Fums. Therefore, the aim of this study was to explore the effects of FB1 on the oxidative stress and tight junctions of the pig iliac endothelial cells (PIECs) in vitro. The results showed that FB1 reduced the viability of PIECs, increased the contents of ...
