Scientists discover a new risk factor for Alzheimer's

...ally pinpoint the precise changes in the gene that contribute to disease. "Now we need to go back and look in the regions around the clusters of SNPs that we tracked and see if we can find additional genetic changes that are either unique or enriched in the individuals with Alzheimer's," said St George-Hyslop. ...

Freeze! Scientists film proteins at work by freezing them at different states

...n and on the other hand there are the results that contribute to the knowledge of how this enzyme works? explains Dominique Bourgeois, corresponding author for the paper. The enzyme filmed in action is called “superoxide reductase? its role is to eliminate a toxic molecule called “superoxide radical? In orde...

Discovery of an HIV inhibitor in human blood points to new drug class

... "Our data support the possibility that VIRIP may contribute to controlling HIV-1 replication in infected individuals and that derivates thereof are highly suitable for development of a new class of HIV-1 inhibitors targeting the highly conserved gp41 fusion protein," the researchers concluded. There are no...

Study uncovers a lethal secret of 1918 influenza virus

...nd victims, in essence, drown. The mechanisms that contribute to the lethality of the virus were uncovered by University of Washington researchers using functional genomics, a technique in which researchers analyze the gene functions and interactions. Learning more about the virulence mechanisms of the 1918 flu...

Largest genomic search finds genes that may contribute to autism

...hromosome as the location of another gene that may contribute to a child's chances of having autism. The findings, based on genetic samples from nearly 1,200 families with two or more children who have autism, were published today in Nature Genetics by more than 120 scientists from Europe and North America who...

Brain networks strengthened by closing ion channels

...tion of cAMP. The dysregulation of the pathway may contribute to increased forgetfulness and susceptibility to distraction as we grow older. The research is also relevant to common disorders such as ADHD, which is associated with weaker regulation of attention and behavior. ADHD is highly heritable, and some...

Experience affects new neuron survival in adult brain; study sheds light on learning, memory

... way in which new neurons in the adult brain could contribute to learning and memory by storing the information of one’s previous experiences," Gage says. Future research, he says, should focus on understanding when new neurons are active during memory-related behavior, how experience affects this activity, and...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...rent web service layer for data access. USM will contribute its natural compound database for use in virtual screening for new inhibitors and drug discovery. CNIC will also become the central repository for the project’s research data. The database will be distributed through the computational data gri...

Cells use 'noise' to make cell-fate decisions

...ed of a distinct set of biochemical reactions that contribute to some biological process. Randomness in those reactions contributes to biological noise, technically referred to as stochastic fluctuations. "Noise in biological systems is a fact of life," said Dr. Süel, a member of the systems biology division...

Liposuctioned fat stem cells to repair bodies

...its surrounding histone proteins. Epigenetic marks contribute to switching genes on and off, and stem cells rely on them heavily as they divide and mature. The Oslo team has found that low rates of DNA methylation, for instance, boost the chances of transforming fat stem cells from one cell type into another. "...

Blocking immune cell action increases Alzheimer's-associated protein deposits

...eta, but the cells also release factors that could contribute to neurodegeneration. The current study was designed to clarify the role of microglia in Alzheimer's and identify factors involved in the immune cells' accumulation at amyloid plaques. The research team focused on a molecule called CCR2, a recep...
