Lithocholic Acid Alleviates Deoxynivalenol-Induced Inflammation and Oxidative Stress via PPARγ-Mediated Epigenetically Transcriptional Reprogramming in Porcine Intestinal Epithelial Cells

Deoxynivalenol (DON) is a common mycotoxin that induces intestinal inflammation and oxidative damage in humans and animals. Given that lithocholic acid (LCA) has been suggested to inhibit intestinal inflammation, we aimed to investigate the protective effects of LCA on DON-exposed porcine intestinal epithelial IPI-2I cells and the underlying mechanisms. Indeed, LCA rescued DON-induced cell death in IPI-2I cells and reduced DON-stimulated inflammatory cytokine levels and oxidative stress. Importantly, the nuclear receptor PPARγ was identified as a key transcriptional factor involved in the DON-induced inflammation and oxidative stress processes in IPI-2I cells. The PPARγ function was found compromised, likely due to the hyperphosphorylation of the p38 and ERK signaling pathways. In contrast, the DON-induced inflammatory responses and oxidative stress were restrained by LCA via PPARγ-mediated reprogramming of the core inflammatory and antioxidant genes. Notably, the PPARγ-modulated transcriptional regulations could be attributed to the altered recruitments of coactivator SRC-1/3 and corepressor NCOR1/2, along with the modified histone marks H3K27ac and H3K18la. This study emphasizes the protective actions of LCA on DON-induced inflammatory damage and oxidative stress in intestinal epithelial cells via PPARγ-mediated epigenetically transcriptional reprogramming, including histone acetylation and lactylation.
