Placental Expression of EG-VEGF and Its PROKR1 and PROKR2 Receptors in Preeclampsia Patients.

Placental Expression of EG-VEGF and Its PROKR1 and PROKR2 Receptors in Preeclampsia Patients.

The pathophysiology of preeclampsia (PE) is thought to be endothelial dysfunction responsible for the maternal signs of de novo hypertension and proteinuria after 20 weeks. Current concepts suggest that the pathophysiology of preeclampsia and intrauterine growth retardation results from an imbalance of angiogenic factors.

A new angiogenic factor EG-VEGF (Endocrine Gland- Derived Vascular Endothelial Growth Factor) also known as Prokineticin 1 (PROK1) appears to be emerging in the pathophysiology of PE. EG-VEGF is a circulating factor which belongs to the family of prokinetics. Dr Alfaidy's MAB2 team at the Cancer and Infections Biology Laboratory (U1292 Biosanté INSERM / UGA / CEA, CEA Grenoble) demonstrated its key role in the control of key processes in placental development and provided evidence through the development of an animal model of preeclampsia. EG -VEGF is directly involved in the development of Pre-Eclampsia. Few studies have evaluated the expression of EG-VEGF in the human placenta.
