First demonstration of new hair follicle generation in an animal model
...er can regenerate large portions, but it is not de novo
regeneration; some of the original liver has to remain so that it can regenerate.) In this study, researchers found that wound healing in a mouse model created an “embryonic window?of opportunity. Dormant embryonic molecular pathways were awakened...
Blood sugar's manufacture limited by building blocks' supply
...hortage, a condition known as hypoglycemia. The de novo
synthesis of glucose depends on the availability of a substrate molecule that comes from an amino acid. The researchers found that mice with a targeted deletion of KLF15 display severe hypoglycemia after an overnight fast. They further found evide...

Pathway toward gene silencing described in plants
... make the DNA accessible for methylation by the de novo
cytosine methyltransferase, DRM2. A paradoxical aspect of the pathway is that siRNAs direct DNA methylation but DNA methylation is also required for the production siRNAs. "It's a circular pathway. You have to produce the siRNA in order to have t...
Fat's fate depends on its source
...iet should include an adequate source of fat. "De novo
synthesis of fat is an energy-expensive process whose role in adult mammals is poorly understood," said study senior author Clay Semenkovich, of Washington University School of Medicine. "The current study supports the notion that the source of fats ...
