Abstract/OtherAbstract:
Endocrine gland vascular endothelial growth factor (EG-VEGF) is a novel angiogenic mitogen selective for endothelial cells (EC) in endocrine glands. EG-VEGF is identical to a protein previously cloned and termed prokineticin (PK)-1. The present study examined the expression of EG-VEGF/PK-1 and its receptors in ovarian steroidogenic cells and EC and compared the regulation of EG-VEGF/PK-1 and VEGF expression in SV40 transformed luteinized human granulosa cell line (SVOG). Normal granulosa or SVOG cells expressed EG-VEGF/PK-1 mRNA. Incubation of SVOG cells with forskolin augmented EG-VEGF/PK-1 expression in a dose-dependent manner. Chemical hypoxia induced by CoCl(2) and desferrioxamine mesylate (100 micro M each) markedly reduced EG-VEGF/PK-1. In contrast, hypoxia significantly elevated VEGF mRNA (VEGF165, 189) and protein secretion. Thrombin, like hypoxia, also induced an opposite effect on VEGF and EG-VEGF/PK-1. Whereas EG-VEGF/PK-1 and VEGF were inversely regulated, steroidogenesis and EG-VEGF/PK-1 were positively correlated in SVOG cells. A distinct pattern of ovarian PK receptor (PK-R) expression was observed in which steroidogenic cells predominantly express PK-R1 receptors, whereas corpus luteum-derived EC express high levels of both PK-R1 and PK-R2. Therefore, acting via either PK-R2 or PK-R1, EG-VEGF/PK-1 may have angiogenic as well as nonangiogenic functions in the ovary.
