Preeclampsia, a hypertensive pregnancy complication, is largely unpredictable in healthy nulliparous pregnant women. Accurate preeclampsia prediction in this population would transform antenatal care. To identify novel protein markers relevant to the prediction of preeclampsia, a 3-step mass spectrometric work flow was applied. On selection of candidate(More)
Pre-eclampsia is a multi-system disorder of pregnancy with major maternal and perinatal implications. Emerging therapeutic strategies are most likely to be maximally effective if commenced weeks or even months prior to the clinical presentation of the disease. Although widespread plasma alterations precede the clinical onset of pre-eclampsia, no single(More)
OBJECTIVE To determine levels of matrix metalloproteinase (MMP)-2 and MMP-9, and the tissue inhibitors of metalloproteinases (TIMP)-1 and TIMP-2 in the plasma of women destined to develop preeclampsia prior to the onset of clinical disease. STUDY DESIGN Plasma samples were taken from women whose pregnancies were subsequently complicated by preeclampsia(More)
More than half of all cases of preeclampsia occur in healthy first-time pregnant women. Our aim was to develop a method to predict those at risk by combining clinical factors and measurements of biomarkers in women recruited to the Screening for Pregnancy Endpoints (SCOPE) study of low-risk nulliparous women. Forty-seven biomarkers identified on the basis(More)
Blockade of small-conductance Ca (2)(+)-activated K(+) channels (SK(Ca)) and intermediate conductance Ca(2)(+)-activated K(+) channels (IK(Ca)) can cause inhibition of endothelium-dependent hyperpolarizing factor (EDHF) in many vascular beds from animals, but there is a relative paucity of data in human vessels. Systemic arteries, isolated from women with(More)
'Omic' technologies represent a strategy towards high-throughput, simultaneous analysis of thousands of biological molecules. Their development has been accelerated in the post-genomic era since these molecules represent the interaction of genes and environment or the 'functional genome'. Omic domains are of particular interest in the search for predictive(More)
OBJECTIVE Progress in the prevention and treatment of women at risk of pre-eclampsia (PE) still remains hindered by the lack of clinical screening tools that can accurately predict which mothers are at risk. The identification and validation of predictive biomarkers is therefore seen as a critical milestone towards improved healthcare provision and the(More)
Characterizing the protein factors released from placentae during pathogenesis remains a key objective toward understanding preeclampsia and related pregnancy disorders. Gel-free proteomics technologies applied to placental explant-conditioned media offers the potential of identifying these factors. Relative quantification mass spectrometry using isobaric(More)
OBJECTIVE Pregnant women with the vascular complication of preeclampsia show altered lipid metabolism characterized by elevated circulating triglycerides and nonesterified free fatty acids. We have compared the effect of maternal plasma from women with and without preeclampsia on cultured vascular endothelial cells and determined whether these(More)
Worldwide, pre-eclampsia and eclampsia contribute to the death of a pregnant woman every 3 min. In the UK in recent decades, hypertensive disorders of pregnancy have remained one of the leading causes of both maternal and perinatal morbidity and mortality. The management of pregnancies complicated by hypertension has not significantly altered for many(More)
