OBJECTIVE
To investigate the possible impact of thrombin on soluble Fms-like tyrosine kinase 1 (sFlt-1) expression in trophoblasts.
METHODS
Experimental.
METHODS
University hospital laboratory.
METHODS
A trophoblast cell line (HRT-8/SVneo) was treated with thrombin, protease-activated receptor 1
The primary placental defect in preeclampsia is shallow trophoblast invasion of the decidua leading to incomplete vascular transformation and inadequate uteroplacental perfusion. Soluble fms-like tyrosine kinase-1 (sFlt-1) seems to interfere with these events by inhibiting local angiogenesis and/or
OBJECTIVE
The purpose of this study was to determine if maternal serum concentrations of placenta growth factor (PlGF) and soluble Fms-like tyrosine kinase 1 receptor (s-Flt1) are more abnormal in patients with severe preeclampsia compared with mild preeclampsia.
METHODS
Serum samples were collected
The primary driving force in preeclampsia (PE) appears to be excessive secretion of fms-like tyrosine kinase-1 (sFlt-1), a truncated decoy receptor for vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) that induces systemic endotheliopathy by depriving endothelial cells of
BACKGROUND
Increased maternal plasma levels of proinflammatory cytokines as well as the anti-angiogenic agents soluble fms-like tyrosine kinase 1 (sFlt-1) and endoglin (sEng) are associated with promoting vascular dysfunction leading to the maternal syndrome of preeclampsia.
OBJECTIVE
Nulliparous
Invasive deficiency of the trophoblast and poor remodeling of the uterine spiral arteries were probably the primary pathogenesis causes of preeclampsia (PE). The expression of receptor tyrosine kinase-like orphan receptor 1 (ROR1) during embryogenesis had been previously confirmed and OBJECTIVE
We measured maternal serum soluble fms-like tyrosine kinase 1 concentrations across pregnancy and immediately postpartum in women who developed preeclampsia and normal pregnant women.
METHODS
This was a nested case control study of 113 normal pregnant women and 55 women with
OBJECTIVE
To explore angiogenic factor differences in preeclamptic patients according to the absence or presence of underlying vascular disease.
METHODS
We prospectively compared serum soluble fms-like tyrosine kinase 1 (sFlt1), soluble endoglin, and placental growth factor (PlGF) from 41
The pathophysiology of preeclampsia remains largely unknown. A number of circulating placenta-produced factors have been implicated in causing the endothelial dysfunction and the clinical phenotype characteristic of preeclampsia.
OBJECTIVE
Determination of serum levels of placental soluble fms-like
OBJECTIVE
Performance evaluation of the novel BRAHMS KRYPTOR soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PlGF) assays.
METHODS
Intra- and inter-assay imprecision, functional sensitivity, linearity in dilution, method comparison, and diagnostic capacity were
T helper (Th)1 cytokine-predominating status and compromised placental vasculature is thought to be central to the pathogenesis of preeclampsia. However, it remains to be clarified how these two phenomena relate to each other. We have reported that lymphokine-activated killer (LAK) cells induced
OBJECTIVE
The aim of this investigation was to assess soluble endoglin (sEng) and soluble fms-like tyrosine kinase-1 (sFlt1) as first-trimester serum markers to predict preeclampsia.
METHODS
First-trimester sera were obtained from 46 women with subsequent late-onset preeclampsia and from 92
OBJECTIVE
To estimate whether alterations in plasma levels of the proangiogenic proteins placental growth factor (PlGF) and vascular endothelial growth factor-A (VEGF-A), and the antiangiogenic protein soluble fms-like tyrosine kinase-1 (sFlt1) were more pronounced in early-onset than in late-onset
OBJECTIVE
To investigate the maternal plasma concentration of soluble fms-like tyrosine kinase-1 (sFlt-1) and free vascular endothelial growth factor (free-VEGF) at 11 to 13 weeks of gestation in patients destined to develop preeclampsia (PE) and to examine whether any possible differences in
Background: We retrospectively investigated soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) ratios and screen-positive rates according to cutoff values for preeclampsia risk assessment based on the number of
