'Open' stem cell chromosomes reveal new possibilities for diabetes

Stem cells hold great promise for treating a number of diseases, in part because they have the unique ability to differentiate, specializing into any one of the hundreds of cell types that comprise the human body. Harnessing ...

CNIO researchers delve into the behavior of cohesins

Cohesins are protein complexes that join the two copies of each chromosome—called sister chromatids—to ensure that they are shared fairly between the daughter cells during cell division. In this way, each daughter cell ...

Preventing the spread of repression

Scientists at the Friedrich Miescher Institute for Biomedical Research have identified a novel and unexpected regulatory activity of RNA at the edge of inactive chromosomal regions. In their publication in Nature Structural ...

New light shed on chromosome fragility

Why are certain chromosome regions prone to breakages? The answer is crucial, as this fragility is involved in the development of tumors. A team from the Institut de Génétique et de Biologie Moleculaire et Cellulaire ...

Pairing up: How chromosomes find each other

After more than a century of study, mysteries still remain about the process of meiosis -- a special type of cell division that helps insure genetic diversity in sexually-reproducing organisms. Now, researchers at Stowers ...

Scientists Study Holstein Milk Production, Fertility

(PhysOrg.com) -- Agricultural Research Service (ARS) scientists have discovered why Holsteins—bred to produce more milk—are less fertile than before breeding efforts were stepped up to increase dairy production: It's ...
