In PE placentas, YTHDF2 was downregulated and NCOA4 upregulated, consistent with in vitro findings. NCOA4 overexpression impaired trophoblast function and increased ferroptosis, whereas silencing had protective effects. YTHDF2 knockdown and NCOA4 overexpression acted synergistically to exacerbate ferroptosis, both in trophoblasts and in a PE mouse model, leading to aggravated hypertension, proteinuria, and fetal growth restriction, which were partially reversed by Fer-1.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      WTAP suppresses ferroptosis in PE by enhancing YTHDF2-dependent m\n                      <jats:sup>6<\/jats:sup>\n                      A methylation and degradation of NCOA4.
