Body's Own Recycling System

Researchers discover "molecular emergency brake" in charge of regulating self-digestion Times of distress literally eat away at the core of starving cells: They start to digest their own parts and recycle them for metabolic purposes. This process — called autophagy — also plays a role in immune defense. In that context, however, the digestive machinery is switched on for an entirely different purpose: the elimination of pathogens that have invaded the body. Now, Prof. Ingo...

An international team of scientists have shown at an unprecedented level of detail how cells prioritize the repair of genes containing potentially dangerous damage. The research, published in the journal Nature and involving academics from the University of Bristol, the Institut Jacques-Monod in France and Rockefeller University in the US, studied the action of individual molecules in order to understand how cellular repair pathways are triggered. The genetic information that forms the...

'Promiscuous' Enzymes Still Prevalent In Metabolism Shown By New Study
2012-08-31 13:12:26

Challenges fundamental notion of enzyme specificity and efficiency Open an undergraduate biochemistry textbook and you will learn that enzymes are highly efficient and specific in catalyzing chemical reactions in living organisms, and that they evolved to this state from their “sloppy” and “promiscuous” ancestors to allow cells to grow more efficiently. This fundamental paradigm is being challenged in a new study by bioengineers at the University of California, San...

Why Cells And Organelles Don't Get Stuck

Researchers explain 'hydration repulsion' between biomembranes Biomembranes enclose biological cells like a skin. They also surround organelles that carry out important functions in metabolism and cell division. Scientists have long known in principle how biomembranes are built up, and also that water molecules play a role in maintaining the optimal distance between neighboring membranes–otherwise they could not fulfill their vital functions. Now, with the help of computer...

Numerous viruses are used in the service of science today. They serve as gene taxis to transfer therapeutic genes into body cells or as therapeutic viruses targeted to infect and destroy cancer cells. For such applications, the viruses are often equipped with additional genes, such as for immune mediators or for proteins inducing programmed cell death. However, these gene products can harm the body if they are released at the wrong moment or at excessive levels. "Ideally, we want to be able...

Pioneering mass spectrometry methods developed at the U.S. Department of Energy´s (DOE´s) Ames Laboratory are helping plant biologists get their first glimpses of never-before-seen plant tissue structures. The new method opens up new realms of study, ones that might have long-ranging implications for biofuels research and crop genetics. “The data we´re seeing are unprecedented,” said Basil Nikolau, the Ames Laboratory faculty scientist heading up the project,...

Cell (journal)
2012-06-04 14:15:36

Cell is a peer-reviewed scientific journal founded by Benjamin Lewin in January 1974 with the sponsorship of MIT Press. Lewin bought the rights to the journal in 1986 and published it under his own publishing arm Cell Press. Cell Press was sold to Elsevier in 1999, which currently publishes Cell twice monthly. Cell Press publishes several biomedical journals, including Cell, Neuron, Immunity, Molecular Cell, Developmental Cell, Cancer Cell, Current Biology, Structure, Chemistry &...
