Researchers solve a protein complex's molecular structure to explain its role in gene silencing
A cell's genome maintains its integrity by organizing some of its regions into a super-compressed form of DNA called heterochromatin. In the comparatively simple organism fission yeast, a cellular phenomenon known as RNA ...

NETs catch platelets and induce clots, linking inflammation with thrombosis
(PhysOrg.com) -- Neutrophils are the innate immune system's 'first responders,' fighting infection in several distinct ways. These white blood cells can engulf foreign particles via phagocytosis, or they may release antimicrobial ...

2 signals -- from within and out of cell -- specify motor neuron differentiation
Two signals - an external one from retinoic acid and an internal one from the transcription factor Neurogenin2 - cooperate to activate chromatin (the basic material of chromosomes) and help determine that certain nerve progenitor ...

Researchers explain process by which cells 'hide' potentially dangerous DNA segments
The DNA in the 23 pairs of chromosomes in each of the billions of cells of the human body is so tightly packed that it would measure six feet in length if stretched end to end. A genome of this size can squeeze into a cell's ...
