The expression of ATF2 was detected using immunohistochemistry and western blot analysis, and its correlation with clinical maternal and neonatal outcomes was analyzed. The trophoblast cell line HTR8\/SVneo was infected with ATF2\u2010overexpressing or interfering lentivirus and stimulated with high glucose to assess changes in cell viability and ferroptosis. Transcriptome sequencing and functional experiments were conducted to identify potential downstream pathways of ATF2.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We found that ATF2 is highly expressed in GDM placental tissues and in trophoblast cells under high glucose conditions, and its overexpression is significantly positively correlated with increased levels of ferritin (<jats:italic>P<\/jats:italic>\u2009=\u20090.010), triglycerides (<jats:italic>P<\/jats:italic>\u2009=\u20090.039), and total cholesterol (<jats:italic>P<\/jats:italic>\u2009=\u20090.044) in GDM patients. Exogenous ATF2 expression further suppresses the proliferation of HTR8\/SVneo cells under high glucose stimulation and promotes an increase in ferroptosis. Mechanistically, ATF2 targets the inhibition of the PI3K\/Akt\/Nrf2 pathway, reducing Nrf2 nuclear translocation and decreasing glutathione peroxidase 4 (GPX4) expression, thereby promoting ferroptosis in trophoblast cells and reducing their viability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>ATF2 regulates ferroptosis and impacts trophoblast function
