Gene mutation causes lethally low-fat diet
...These vesicles connect with the Golgi apparatus, a labyrinth of membranes filled with enzymes that modify the fats, and then new vesicles transport the fats out of the cell and into the bloodstream. The researchers found that this process is disrupted in the fat free mutants, preventing fats from reaching the ...New roles for growth factors: Enticing nerve cells to muscles
...usions called axons that sniff their way through a labyrinth of attractive and repulsive chemical cues that guide them to their target. While several recent studies discovered molecules that repel motor neuron axons from incorrect targets in the limb, scientists at the Salk Institute for Biological Studies ha......ted flow patterns. "Pinching off one part of the labyrinth can have a good effect, but it can also have unexpected consequences, or even no effect because of redundancy built into metabolic systems," Palsson said. "The new tool we've created allows scientists to tinker with a virtual metabolic system in ways...
