New research by scientists at the University of Exeter has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide - a finding with potential links to the underlying causes of many cancers. The study, published today in Developmental Cell, describes a number of routes to the formation of a microtubule spindle – the tracks along which DNA moves when a cell divides in order to make two genetically identical cells. In order to understand the...

A new gene mutation which will help doctors give a more accurate diagnosis of a particular type of brain and muscle disease in children has been discovered for the first time by University of Leeds experts. Mitochondrial myopathy, as it is known, causes muscle weakness, movement problems and learning difficulties and affects more than 70,000 people in the UK. For the first time, mutations in a particular gene, MICU1, have been linked to myopathy. The discovery gives a better...

New England Peptide (NEP), a Massachusetts based biotech manufacturer, and The Atlantic Cancer Research Institute (ACRI), a leading cancer research center in Atlantic Canada, have launched a new biotech company. Excipio Technologies Inc. has a mandate to commercialize the Vn96 peptide developed by both NEP and ACRI for the isolation of exosomes and extracellular microvesicles. Gardner, MA (PRWEB) December 13, 2013 Vn96 is a synthetic peptide that was designed to specifically stick to...

Astronauts Diagnosed With Eye Problems After Returning From Space
2013-12-11 16:34:15

NASA Those who travel to space are rewarded with a beautiful sight – planet Earth. But the effects of space travel on the human sense of sight aren’t so beautiful. More than 30 percent of astronauts who returned from two-week space shuttle missions and 60 percent who spent six months aboard the International Space Station were diagnosed with eye problems. Two recent investigations examined mechanisms that may explain eye changes in spaceflight, help find ways to minimize this health...

Shifts in zinc's location could be exploited for early diagnosis of prostate cancer Zinc, an essential nutrient, is found in every tissue in the body. The vast majority of the metal ion is tightly bound to proteins, helping them to perform biological reactions. Tiny amounts of zinc, however, are only loosely bound, or "mobile," and thought to be critical for proper function in organs such as the brain, pancreas, and prostate gland. Yet the exact roles the ion plays in biological systems...

Intracellular ABC Transporters Allow Leaf Beetle Larvae To Accumulate Defensive Substances When Feeding

Max Planck Institute for Chemical Ecology Similar membrane proteins play a crucial role in the transport of toxic substances out of the cell Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by the insects to fend off predators: ABC transport proteins, which are found in large quantities in glandular cells of the larvae. The poplar leaf...

Tokyo, Nov 29, 2013 - (ACN Newswire) - Researchers at Waseda University in Japan have identified key information to help explain the formation of the "spindle apparatus", a structure required for cell division. Their findings shed light on the mechanisms behind "self-organization" - an essential characteristic of biological structures.Organisms are composed of a variety of structures including muscles, internal organs, and brains, all of which are created through a process known as...

[ Watch The Video: Capturing the Carboxysome in Motion ] DOE/Joint Genome Institute Cyanobacteria, found in just about every ecosystem on Earth, are one of the few bacteria that can create their own energy through photosynthesis and "fix" carbon – from carbon dioxide molecules – and convert it into fuel inside of miniscule compartments called carboxysomes. Using a pioneering visualization method, researchers from the University of California, Berkeley and the Department of Energy...

Study Sheds Light On Treatment For Parkinson's Disease
2013-11-25 07:02:43

NIH/National Institute of Neurological Disorders and Stroke Scientists at the National Institutes of Health have used RNA interference (RNAi) technology to reveal dozens of genes which may represent new therapeutic targets for treating Parkinson's disease. The findings also may be relevant to several diseases caused by damage to mitochondria, the biological power plants found in cells throughout the body. "We discovered a network of genes that may regulate the disposal of dysfunctional...
