The Human Cell Atlas is already helping to ensure safer pregnancies, and scientists believe it will help them understand many other conditionsIt provides oxygen and nutrients for a growing baby, removes waste products as they build up in its blood, and protects the life of the foetus. Yet the placenta, the temporary organ that cherishes the unborn, is a puzzle. It carries the D...

The protein FKBP51 is considered a risk factor for psychiatric disorders. However, for the first time, new research results have shown positive effects. Instead of making people anxious or impairing their ability to think, the protein can have the opposite effect and thus promote resilience. The effect it has depends on the type of cells in which it becomes active....

A sub-study analysis of the EAST—AFNET 4 trial revealed how genetic risk for atrial fibrillation (AF) and stroke interacts with early rhythm control therapy: Early rhythm control reduces cardiovascular events in patients with AF across the spectrum of genetic AF and stroke risks. The findings were published in the journal Cardiovascular Research....

The RPE and choroid, located behind the human retina, are fundamental to vision, playing a myriad of roles from light absorption to providing oxygenated blood to the photoreceptor cells. However, our understanding of the gene expressions within these cells and how they contribute to retinal diseases has been limited....

Researchers from Children's Hospital of Philadelphia (CHOP) recently discovered that extremely thorough "deep sequencing" of the genome in tissue samples and cell-free DNA of patients with potentially life-threatening vascular anomalies captured several genetic variants related to disease that were not captured with conventional genetic sequencing methods. More than 60% of pati...

So far, it has not been possible to explain the causes of around half of all rare hereditary diseases. A Munich research team has developed an algorithm that predicts the effects of genetic mutations on RNA formation six times more precisely than previous models. As a result, the genetic causes of rare hereditary diseases and cancer can be identified more precisely....

A Harvard-led study has identified genetic markers associated with preeclampsia and gestational hypertension in a large cohort study. In the paper, "Polygenic prediction of preeclampsia and gestational hypertension," published in Nature Medicine, the researchers detail how these genetic markers could be used as a predictive risk assessment and offers mechanistic insights into p...
