Molecular insights into the corin function at the uteroplacental interface

Area of Science:

• Reproductive biology
• Vascular physiology
• Endocrinology

Background:

• Cell-cell interactions and tissue remodeling are critical at the uteroplacental interface during pregnancy.
• Molecular mechanisms governing these processes are not fully understood.
• Corin, an enzyme activating atrial natriuretic peptide (ANP), plays a role in cardiovascular and metabolic homeostasis.

Purpose of the Study:

• To review the function of corin at the uteroplacental interface.
• To elucidate the molecular mechanisms underlying corin's role in pregnancy.
• To discuss the implications of corin deficiency in pregnancy-associated diseases.

Main Methods:

• Review of existing literature on corin function in reproductive physiology.
• Analysis of molecular pathways involving corin, ANP, and uterine processes.
• Examination of evidence from mouse models and human studies on corin and preeclampsia.

Main Results:

• Uterine corin, induced by progesterone, activates ANP, promoting decidualization and vascular remodeling.
• Corin influences vascular smooth muscle and endothelial cell death in spiral arteries, crucial for trophoblast invasion.
• Corin regulates decidual macrophages in response to placental ischemia.
• Corin knockout in mice leads to a preeclampsia-like phenotype.
• Corin gene variants and epigenetic changes are associated with preeclampsia in humans.

Conclusions:

• Corin is essential for normal uterine vascular remodeling, decidualization, and immune function during pregnancy.
• Corin deficiency is implicated in the pathogenesis of preeclampsia and other pregnancy complications.
• Understanding corin's role offers insights into potential therapeutic targets for pregnancy disorders.
