Human fetal and placental compartments have all the enzymatic systems necessary to produce steroid hormones. However, their activities are different and complementary: the fetus is very active in converting acetate into cholesterol, in transforming pregnanes to androstanes, various hydroxylases, sulfotransferases, whilst all these transformations are absent or very limited in ...

We previously described activators of peroxisome proliferator-activated receptor gamma (PPAR gamma) in the serum of pregnant women. We have also characterized this activating component by using a hexane-extracted serum fraction to examine PPAR activator levels in normal and preeclamptic (PE) pregnancies. In this study we report that the pregnancy PPAR ...

A successful pregnancy can only occur when the maternal immune system fails to attack the allogeneic fetus. Two plasma proteins with described immunoregulatory activities, pregnancy zone protein (PZP) and placental protein-14 (PP14; also known as glycodelin-A), increase dramatically during pregnancy, prompting us to examine their potential role in mediating fetal ...

We investigated changes in both thrombin activatable fibrinolysis inhibitor (TAFI) antigen levels and its functional effect on in vitro fibrinolysis in normal pregnancy. 152 pregnant women and 31 women in the immediate postpartum period were studied, with pregnancy divided into 6 windows at 4 weekly intervals. As TAFI influences and ...

Mitotic centromere-associated kinesin (MCAK) is a microtubule (MT)-destabilizing molecular motor. In the present study we show that the final 8 amino acids of the C-terminus of MCAK inhibit lattice-stimulated ATPase activity of the motor. Surprisingly, loss of this C-terminal 'tail' (MCAK-Q710) leads to more rapid depolymerization of MTs relative to ...
