RNAi modulation of placental sFLT1 for the treatment of preeclampsia.

Preeclampsia is a placentally induced hypertensive disorder of pregnancy that is associated with substantial morbidity and mortality to mothers and fetuses. Clinical manifestations of preterm preeclampsia result from excess circulating soluble vascular endothelial growth factor receptor FLT1 (sFLT1 or sVEGFR1) of placental origin. Here we identify short interfering RNAs (siRNAs) that selectively silence the three sFLT1 mRNA isoforms primarily responsible for placental overexpression of sFLT1 without reducing levels of full-length FLT1 mRNA.

Increased salt sensitivity in offspring of pregnancies complicated by experimental preeclampsia.

Preeclampsia is a hypertensive disorder of pregnancy known to increase the risk of cardiovascular disease in mothers and offspring. Offspring exposed to a suboptimal intrauterine environment may experience altered fetal programming and subsequent long-term cardiovascular changes. This study investigated changes in the vascular response in offspring from experimental preeclampsia (EPE) induced by uterine artery ligation, in the absence of fetal growth restriction, compared to normal baboon pregnancies (controls), following a high salt diet challenge.

The chronobiology of blood pressure in pregnancy.

This review summarizes the literature to date on the subject of the chronobiology of blood pressure in pregnancy, and more specifically, in the common disease state of high blood pressure in pregnancy or preeclampsia. While the guidelines for treating hypertension in pregnancy use absolute measures to start treatment, they do not take into account the important rhythms of hypertension including nighttime and daytime readings. These variations are likely to have strong impacts on pregnancy outcomes, risk and long-term hypertension risk.

CD83 is a new potential biomarker and therapeutic target for Hodgkin lymphoma.

Chemotherapy and hematopoietic stem cell transplantation are effective treatments for most Hodgkin lymphoma patients, however there remains a need for better tumor-specific target therapy in Hodgkin lymphoma patients with refractory or relapsed disease. Herein, we demonstrate that membrane CD83 is a diagnostic and therapeutic target, highly expressed in Hodgkin lymphoma cell lines and Hodgkin and Reed-Sternberg cells in 29/35 (82.9%) Hodgkin lymphoma patient lymph node biopsies.

The effect of acetyl salicylic acid (Aspirin) on trophoblast-endothelial interaction in vitro.

Early administration of low dose acetyl salicylic acid (Aspirin) in high risk women reduces the risk of early onset preeclampsia. This study aims to investigate the effect of aspirin on trophoblast integration and the its effect on angiogenic and invasive pathways in an in-vitro model of preeclampsia. Red fluorescent-labeled human uterine myometrial microvascular endothelial cells (UtMVECs) were seeded on matrigel to form endothelial networks.

A Cross-Sectional Study of Ageing and Cardiovascular Function over the Baboon Lifespan.

Background: Ageing is associated with changes at the molecular and cellular level that can alter cardiovascular function and ultimately lead to disease. The baboon is an ideal model for studying ageing due to the similarities in genetic, anatomical, physiological and biochemical characteristics with humans. The aim of this cross-sectional study was to investigate the changes in cardiovascular profile of baboons over the course of their lifespan.
