Fumonisins (Fums) are mycotoxins widely distributed in crops and feed, and ingestion of Fums-contaminated crops is harmful to animal health. The purpose of this study is to explore the effect of Fum B1 (FB1) on barrier functions of porcine intestinal epithelial cells, IPEC-J2, to clarify the intestinal toxicity of Fums in pigs. The results showed that the persistent treatment of FB1 significantly decreased the viability of IPEC-J2. Moreover, the expressions of Claudin 1, Occludin, Zonula Occluden-1 (ZO-1) on the messenger RNA (mRNA), and protei...
