RIVERSIDE, Calif. — Sexual selection refers to species' selection for traits that are attractive to the opposite sex. This special type of natural selection enhances opportunities to mate, the tail of ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

Researchers found that low oxygen in preeclamptic placentas increases BACE1 activity and amyloid-β production. These proteins form fibrils that disrupt placental cell fusion by triggering excessive ...

The first stages of placental development take place days before the embryo starts to form in human pregnancies. The finding highlights the importance of healthy placental development in pregnancy, ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the developing fetus with what it needs to thrive during gestation. The placenta ...

A deficit in the way the placenta expresses the gene for a hormone called insulin-like growth factor 1 (IGF-1) appears linked to insulin resistance during pregnancy, researchers reported. Photo by ...

Research published yesterday in the journal Nature provides further insight into how the placenta differs from other human organs. Led by scientists from the Wellcome Sanger Institute and the ...

Scientists working with an experimental mouse model at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have identified the essential role of the gene GPR126 in the development of the ...

Elevated levels of type I interferon (IFN) during pregnancy are associated with intrauterine growth retardation, preterm birth, and fetal demise through mechanisms that are not well understood. A ...

During pregnancy, the placenta secretes hormones that increase insulin resistance, which may cause gestational diabetes (GD). Left untreated, diabetes can damage the placenta. GD begins in the ...
