ABSTRACT
FPMH (Fluroxypyr-1-methylheptyl ester) is a synthetic auxin herbicide used in agriculture. The mechanism by which FPMH induces adverse effects in porcine trophectoderm (pTr) and porcine uterine luminal epithelial (pLE) cells, which are involved in porcine implantation, have not been studied yet. Therefore, the present study investigates the toxicological effects of FPMH on pTr and pLE cells. We confirmed that FPMH induced cytotoxic effects on the cells, including apoptosis induction, mitochondrial membrane potential (MMP) depolarization, and ROS production. The phosphorylation of the MAPK pathway (ERK1/2, JNK, and p38) was dysregulated by FPMH administration. In addition, FPMH could suppress cell-cell adhesion and migration abilities of pTr and pLE, which are crucial for implantation. Therefore, exposure to FPMH induced adverse effects in pTr and pLE cells and could result in implantation failure.
