Mitochondria are the body's energy producers, the power stations inside our cells. Researchers at the University of Gothenburg, Sweden, have now identified a group of mitochondrial proteins, the absence of which allows other protein groups to stabilise the genome. This could delay the onset of age-related diseases and increase lifespan. Some theories of human ageing suggest that the power generators of the cell, the mitochondria, play a part in the process. In addition to supplying us with...

Scientists have discovered a new component of mitochondria that plays a key part in their function. The discovery, which is presented in the journal Cell Metabolism, is of potential significance to our understanding of both inherited and age-related diseases. Mitochondria are normally called the cell's power plants since they convert the energy in our food into a form that the body can use. To work properly, the mitochondria have to form new proteins, which they do in their ribosomes. A group...

FINDINGS: Whitehead Institute scientists report that two proteins once thought to have only supporting roles, are the true "stars" of the kinetochore assembly process in human cells. RELEVANCE: The kinetochore is vital to proper DNA distribution during cell division. This finding suggests that scientists may be able to stimulate kinetochore assembly in a process that could lead to new genetic research tools, such as efficient creation of artificial human chromosomes. Widespread use of...

Laboratory reports success in blocking the lethal effects of ALS Brandeis researchers have made a significant advance in the effort to understand amyotrophic lateral sclerosis (ALS) by successfully reversing the toxicity of the mutated protein in the familial type of the disease. Currently there is no cure or prevention for the disease, which affects nerve cells in the brain and the spinal cord. Most frequently referred to as Lou Gehrig's disease, after its most famous victim, ALS typically...

Research in the worm is shedding light on a protein associated with a number of different human cancers, and may point to a highly targeted way to treat them.University of Wisconsin-Madison scientists were studying a worm protein called TFG-1, which is present in many cell types but whose exact role had never been understood. The scientists discovered that the protein controls key aspects of the movement, or secretion, of growth factors out of cells."TFG-1 has never been implicated in the...

In two new studies, researchers provide the first detailed view of the elaborate chemical and mechanical interactions that allow the ribosome "“ the cell's protein-building machinery "“ to insert a growing protein into the cellular membrane. The first study, in Nature Structural and Molecular Biology, gives an atom-by-atom snapshot of a pivotal stage in the insertion process: the moment just after the ribosome docks to a channel in the membrane and the newly forming protein winds...

Discovery points to a potential co-contributor to cilia-related diseases Researchers at the University of Massachusetts Medical School have described a previously unknown role for the cilia protein IFT88 in mitosis, the process by which a dividing cell separates its chromosomes containing the cell's DNA into two identical sets of new daughter cells. Published in advance online by Nature Cell Biology, this newly discovered function for IFT88 suggests a possible alternative or contributory...

Research by University of Warwick's School of Life Sciences has opened up a new path to produce water efficient seeds that will be a significant tool to help create drought resistance, and ensure global food security.  The research not only provides the best map to date of the key protein that appears to be the principal gateway for water intake during seed germination - it also actually provides the right map as it appears much of the research to date was focussed on a much less...

One bad apple is all it takes to spoil the barrel. And one misfolded protein may be all that's necessary to corrupt other proteins, forming large aggregations linked to several incurable neurodegenerative diseases such as Huntington's, Parkinson's and Alzheimer's. Stanford biology Professor Ron Kopito has shown that the mutant, misfolded protein responsible for Huntington's disease can move from cell to cell, recruiting normal proteins and forming aggregations in each cell it visits. Knowing...
