Estrogen rapidly activates the PI3K/AKT pathway and hypoxia-inducible factor 1 and induces vascular endothelial growth factor A expression in luminal epithelial cells of the rat uterus
Biology of reproduction ·doi:10.1095/biolreprod.109.076117

We have previously shown that 17beta-estradiol (E(2)) increases vascular endothelial growth factor A (Vegfa) gene expression in the rat uterus, resulting in increased microvascular permeability, and that this involves the simultaneous recru…

Increased expression of vascular endothelial growth/permeability factor in the rat ovary following an ovulatory gonadotropin stimulus: potential roles in follicle rupture
Biology of reproduction ·doi:10.1095/biolreprod52.6.1426

Ovulation is accompanied by a large increase in the permeability of the capillaries surrounding the follicle, beginning a few hours after the ovulatory stimulus. The resulting edema may play a role in ovulation as well as in the formation a…
