GERMLINE PROKINETICIN RECEPTOR 2 (PROKR2) VARIANTS ASSOCIATED WITH CENTRAL HYPOGONADISM CAUSE DIFFERENTAL MODULATION OF DISTINCT INTRACELLULAR PATHWA…

2013

INTRODUCTION: Defects of prokineticin pathway affect the neuroendocrine control of reproduction, but their role in the pathogenesis of central hypogonadism remains undefined, and the functional impact of the missense PROKR2 variants has been incompletely characterized. MATERIAL AND METHODS: In a series of 246 idiopathic central hypogonadism patients, we found three novel (p.V158I, p.V334M, and p.N15TfsX30) and six already known (p.L173R, p.T260M, p.R268C, p.V274D, p.V331M, and p.H20MfsX23) germline variants in the PROKR2 gene. We evaluated the effects of seven missense alterations on two different prokineticin receptor 2 (PROKR2)-dependent pathways: inositol phosphate-Ca(2+) (Gq coupling) a…

Imbalance of expression of bFGF and PK1 is associated with defective maturation and antenatal placental insufficiency.

2013

Abstract Objective Defective placental maturation is associated with restricted functional capacity and adverse perinatal fetal outcomes. The aim of the study was a comparative analysis of the role of mRNA expression of various angiogenic factors in placental maturation defects. Study design We examined the mRNA expression patterns of prokineticin 1 (PK1), its receptors (PKRs), basic-fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) in tissue from third-trimester placentae that exhibited delayed or accelerated villous maturation. Results The expression of PK1 and PKR2 was elevated in placental tissue exhibiting accelerated maturati…
