Down-Regulation of CPEB4 Alleviates Preeclampsia through the Inhibition of Ferroptosis by PFKFB3

Gestational diabetes mellitus (GDM) complicated with preeclampsia can lead to polyhydramnios, ketosis. Herein, we explored that CPEB4 in cancer progression of preeclampsia and its underlying mechanism. All the serum samples were collected from patients with preeclampsia. These was the induction of CPEB4 in patients with preeclampsia. The serum of CPEB4 mRNA expression was positive correlation with Proteinuria, systolic blood pressure and diastolic blood pressure in patients. The serum of CPEB4 mRNA expression was also negative correlation with body weight of infant in patients. The serum of CPEB4 mRNA expression also was negative correlation with GPX4 level and GSH activity level in patients. The serum of CPEB4 mRNA expression was positive correlation with iron content in patients. CPEB4 gene inhibited trophoblast cell proliferation. CPEB4 gene promoted trophoblast cell ferroptosis by mitochondrial damage. CPEB4 gene induced PFKFB3 expression by the inhibition of PFKFB3 Ubiquitination. PFKFB3 inhibitor reduced the effects of CPEB4 on cell proliferation and ferroptosis of trophoblast cell. Taken together, the CPEB4 promoted trophoblast cell ferroptosis through mitochondrial damage by the induction of PFKFB3 expression, CPEB4 as an represents a potential therapeutic strategy for the treatment of preeclampsia or various types of GDM.
