Increased Sirt1 expression protects against neurodegeneration in HD mouse model

Treatment that increases brain levels of an important regulatory enzyme may slow the loss of brain cells that characterizes Huntington's disease (HD) and other neurodegenerative disorders.

SIRT1 gene appears to delay onset of HD in mouse model

Working with genetically engineered mice, Johns Hopkins researchers have discovered that a gene (SIRT1) linked to slowing the aging process in cells also appears to dramatically delay the onset of Huntington's disease (HD) and slow the progression of the relentless neurodegenerative disorder.

Researchers identify gene that causes PKD/IC in infants

A large, international team of researchers led by scientists at the University of California, San Francisco has identified the gene that causes a rare childhood neurological disorder called PKD/IC, or "paroxysmal kinesigenic dyskinesia with infantile convulsions," a cause of epilepsy in babies and movement disorders in older children.

Researchers discover miR-520 blocks cancer-promoting signaling pathway

MicroRNAs or miRNAs are tiny RNA molecules that have only about 20 nucleotides and do not code for proteins. They regulate many important processes in cells by binding to target messenger RNAs - the instructions for protein production -, thus blocking production of the respective protein. In cancer, the production of some miRNAs is often reduced or amplified. This particularly affects miRNAs that regulate the activity of cancer-promoting genes.

Microvascular stamp stimulates, directs blood vessel growth on wound surface

Researchers have developed a bandage that stimulates and directs blood vessel growth on the surface of a wound. The bandage, called a "microvascular stamp," contains living cells that deliver growth factors to damaged tissues in a defined pattern. After a week, the pattern of the stamp "is written in blood vessels," the researchers report.

F. nucleatum alters endothelial integrity and allows other bacteria to invade human body

A common oral bacteria, Fusobacterium nucleatum, acts like a key to open a door in human blood vessels and leads the way for it and other bacteria like Escherichia coli to invade the body through the blood and make people sick, according to dental researchers at Case Western Reserve University.

Researchers discover how the brain merges sights and sounds

In order to get a better picture of our surroundings, the brain has to integrate information from different senses, but how does it know which signals to combine? New research involving scientists from the Max Planck Institute for Biological Cybernetics, the Bernstein Center for Computational Neuroscience T-bingen, the University of Oxford, and the University of Bielefeld has demonstrated that humans exploit the correlation between the temporal structures of signals to decide which of them to combine and which to keep segregated.

Short spiral-shaped proteins can efficiently deliver DNA segments to cells

Clinical gene therapy may be one step closer, thanks to a new twist on an old class of molecules. A group of University of Illinois researchers, led by professors Jianjun Cheng and Fei Wang, have demonstrated that short spiral-shaped proteins can efficiently deliver DNA segments to cells. The team published its work in the journal Angewandte Chemie.

Researchers identify gene responsible for EMT transformation

Researchers at the Institute for Research in Biomedicine (IRB Barcelona) have identified the gene GATA 6 as responsible for epithelial cells -which group together and are static- losing adhesion and moving towards a new site.

Gates Foundation, Grand Challenges to develop new diagnostics for tropical diseases

Grand Challenges Canada and the Bill & Melinda Gates Foundation have teamed up on an unprecedented global effort to discover and develop affordable, easy-to-use tools to help developing country health workers rapidly diagnose diseases in rural communities. The expected result: more timely and appropriate treatment of illnesses in poor countries, potentially saving countless lives.

Study unveils mechanisms behind neurological effects of penitrem A

The mould fungus Penicillium crustosum occurs relatively frequently in food and animal fodder stored in temperate conditions. This mould produces powerful neurotoxins, for example penitrem A, which causes symptoms that are difficult to distinguish from those of other neurological diseases.
