Abstract
The pulsatile pattern of prostaglandin F2alpha (PGF) secretion during spontaneous luteolysis is well-documented, with multiple pulses of exogenous PGF necessary to induce regression using physiologic concentrations of PGF. However, during spontaneous regression, the earliest pulses of PGF are small and not associated with detectable changes in circulating progesterone (P4), bringing into question what, if any, role these early, subluteolytic PGF pulses have during physiologic regression. To investigate the effect of small PGF pulses, luteal biopsies were collected throughout natural luteolysis in conjunction with bihourly blood samples to determine circulating P4 and PGF metabolite to retrospectively assign biopsies to early and later regression. Whole transcriptome analysis was conducted on CL biopsies. Early PGF pulses altered the luteal transcriptome, inducing differential expression of 210 genes (Q < 0.05) during early regression, compared to 4615 differentially expressed genes during later regression. In early regression, few of these differentially expressed genes were directly associated with luteolysis, rather there were changes in local steroid and glutathione metabolism. Most (94%) differentially expressed genes from early regression were also differentially expressed during later regression, with 98% of these continuing to be altered in the same direction compared to CL at a similar stage of the cycle that had not yet been exposed to PGF. Thus, early, subluteolytic PGF pulses impact the luteal transcriptome, though not by altering steroidogenesis or causing direct inhibition of cellular function. Rather, small pulses alter pathways resulting in removal of cellular support systems, which may sensitize the CL to later pulses of PGF.

Abstract
Preeclampsia (PE) is a gestational disorder with hypertension and proteinuria leading to maternal and fetal morbidity and mortality. Yes-associated protein (YAP), a transcription coactivator of Hippo pathway, was identified as an oncoprotein participated in tumorigenesis. However, the effect of YAP on trophoblast has not been investigated. In our study, YAP expression levels in first-trimester, full-term, and PE placentas were detected using quantitative real-time polymerase chain reaction (PCR), Western blot assays, and immunohistochemistry. Yes-associated protein expression was also detected in BeWo and HTR-8/SVneo. Overexpression plasmid and YAP small interfering RNA were introduced into trophoblast cells. Furthermore, we utilized a Transwell invasion assay, flow cytometry, and Cell Counting Kit-8 analysis to examine the role of YAP in the invasion, apoptosis, and proliferation of HTR-8/SVneo trophoblast cells. The result showed that both YAP messenger RNA (mRNA) and protein expression levels were less in preeclamptic placentas. Yes-associated protein mRNA and protein expression levels were more highly expressed in BeWo. Yes-associated protein enhanced cell invasion, reduced the cellular apoptotic response, and had no effect on proliferation. In addition, the overexpression of YAP activated the expression of caudal-related homeobox transcription factor 2 (CDX2), whereas reduced expression of YAP inhibited the expression of CDX2. Our results demonstrate that decreased YAP levels may contribute to the development of PE by regulating trophoblast invasion and apoptosis involving regulation of CDX2. Collectively, we proposed decreased YAP may contribute to trophoblast dysfunction, which suggests it might represent a prognostic biomarker and therapeutic target for PE.
