BPDE induces human trophoblast cell ferroptosis by up-regulating iron metabolism and promoting GPX4 proteasomal degradation

Human trophoblast cells play important role in embryo-fetal development. However, trophoblast cells are sensitive to environmental carcinogens. Recently, we have discovered that BPDE inhibits trophoblast cell migration, invasion and proliferation, and also increases trophoblast cell apoptosis. Ferro...
