The insect vector always bites twice

...ansmission of the associated diseases. It contains numerous proteins, including immunogenic ones that can modulate or induce a human immune response. Working for the EpiVect programme initiated in 2003 (1), scientists from IRD research unit UR 024 studied this still little known response with the aim of ident...

Brain holds clues to bipolar disorder

...lex machinery inside of nerve cells that regulates numerous processes inside the body. Using animal and cellular models, Dr. Manji and colleagues at NIMH showed that disruptions in these pathways resulted in many of the core symptoms of bipolar disorder and explained many other observations about the disease....

Researchers shed light on mechanism of action used by anti-cancer drug

... the oncogene, Raf, which is frequently mutated in numerous cancers, including leukemia. Oncogenes are typically responsible for promoting tumor growth. Previous findings by Grant’s team, reported in the Journal of Biologic Chemistry, showed that in human leukemia cells, sorafenib lethality was less a cons...

New findings challenge established views on human genome

...of the ENCODE work include: Identification of numerous previously unrecognized start sites for DNA transcription. Evidence that, contrary to traditional views, regulatory sequences are just as likely to be located downstream of a transcription start site on a DNA strand as upstream. Identificatio...

Exploring the dark matter of the genome

... and single-copy genes were assembled by comparing numerous copies with unique or sufficiently distinctive sequences. The assembly was checked by matching it to clones of longer sequences. With the painstaking manual assembly taken as far as practical, the researchers mapped the sequences to their physical lo...

Revealed -- Mosquito genes that could be controlling the spread of killer viruses

...trolling their respective immune systems, but also numerous differences. The team aims to discover which of these genetic differences could explain why one type of mosquito transmits dengue and yellow fevers, while the other transmits malaria. Beyond the present descriptive work, functional studies will be ne...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

Global survey of lizards reveals greater abundance of animals on islands than on mainland ecosystems

...ace, they contain many of the earth’s species with numerous species restricted to single islands,?says Buckley. ?00 million people depend on island ecosystems for their food and livelihoods.? The study suggests that islands are particularly sensitive to the loss and gain of species. Species introductions ...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...enaline for asthma, and is further associated with numerous diseases including those of the cardiovascular and pulmonary systems. If activated for a long period of time the receptors are carried into the cell and are "turned off." In animal, cellular and biochemical experiments, the researchers found that ...

World's leading scientists announce creation of 'Encyclopedia of Life'

.... It will enable us to map and discover things so numerous or vast they overwhelm our normal vision." Scientists began creating individual web pages for species in the 1990s. However, Internet technology needed to mature to allow fast and efficient creation of a comprehensive Encyclopedia. While specifi...

Dealing deadly cancers a knockout punch

...reovirus formulation, Reolysin®, is active against numerous cancers, including intractable sarcomas and melanomas. Recent studies also indicate that Reolysin works synergistically with standard anti-cancer drugs, providing significantly stronger responses than either agent alone. In addition, other s...

Researchers attach genes to minichromosomes in maize

...ularly useful because they allow scientists to add numerous genes onto one minichromosome and manipulate those genes easily because they are all in one place, Birchler said. Genetic modification with traditional methods is more complicated because scientists have little control over where the genes are locate...
