BACKGROUND Placental Protein 13 (PP13), an early biomarker of preeclampsia, is a placenta-specific galectin that binds beta-galactosides, building-blocks of ABO blood-group antigens, possibly affecting its bioavailability in blood. METHODS AND FINDINGS We studied PP13-binding to erythrocytes, maternal blood-group effect on serum PP13 and its performance(More)
Accumulating evidence suggests that oxidative stress plays a pivotal role in dopaminergic neurodegeneration. However, the kinds of proteins involved in the response to oxidative stress remain unclear. In the present study, SH-SY5Y cells were treated with neurotoxin 1-methyl-4-phenyl-pyridinium ion (MPP+) to induce apoptotic neuronal injury. 2D-DIGE followed(More)
Tissue inhibitors of metalloproteinases (TIMPs) inhibit matrix metalloproteinases and some members of a disintegrin and metalloproteinase domain (ADAM) family. In addition, recent studies unveiled novel functions of TIMPs in the regulation of apoptosis. TIMP-1 inhibits intrinsic apoptosis by inducing TIMP-1 specific cell survival pathways involving focal(More)
PURPOSE To demonstrate the constitutive expression and regulation of heparanase (heparan sulfate endoglycosidase) in the normal mouse eye and in mice intracorneally infected with Pseudomonas aeruginosa. METHODS Naïve (unimmunized) and immunized C57BL/6J mice were infected with P. aeruginosa, and corneal heparanase gene and protein expression were detected(More)
BACKGROUND Premature cervical remodeling/ripening is believed to contribute to preterm delivery (PTD), the leading cause of perinatal morbidity and mortality. Despite considerable research, the causes of term and PTD remain unclear, and there is no effective treatment for PTD. We previously demonstrated that complement activation plays a causative role in(More)
OBJECTIVE Preterm birth is associated with 5-18% of pregnancies and is the leading cause of neonatal morbidity and mortality. Amniotic fluid (AF) interleukin-6 (IL-6) is a key cytokine for the identification of intra-amniotic inflammation, and patients with an elevated AF IL-6 are at risk for impending preterm delivery. However, results of the conventional(More)
OBJECTIVE Obesity, insulin resistance, and dyslipidemia are associated with preeclampsia. Recently, "adipose tissue failure", characterized by dysregulation of adipokine production, has been implicated in the pathophysiology of these metabolic complications. Adiponectin, an insulin-sensitizing, anti-atherogenic, anti-inflammatory and angiogenic adipokine,(More)
OBJECTIVE Most anti-angiogenic preeclampsia models in rodents utilized the overexpression of a truncated soluble fms-like tyrosine kinase-1 (sFlt-1) not expressed in any species. Other limitations of mouse preeclampsia models included stressful blood pressure measurements and the lack of postpartum monitoring. We aimed to 1) develop a mouse model of(More)
OBJECTIVE Soluble fms-like tyrosine kinase (sFlt)-1-e15a, a primate-specific sFlt-1-isoform most abundant in the human placenta in preeclampsia, can induce preeclampsia in mice. This study compared the effects of full-length human (h)sFlt-1-e15a with those of truncated mouse (m)sFlt-1(1-3) used in previous preeclampsia studies on pregnancy outcome and(More)
