Fred Hutchinson announces 2005 Harold M. Weintraub Graduate Student Awardees

... among his many contributions, he identified genes responsible for instructing cells to differentiate, or develop, into specific tissues such as muscle and bone. "Hal was one of the most outstanding scientists of his generation, as well as one of the most unpretentious. Hal had the knack of identifying the impor...

NHGRI targets 12 more organisms for genome sequencing

... research community. Each of the working groups is responsible for developing a proposal for a set of genomes to sequence that would advance knowledge in one of two important scientific areas: understanding the human genome and understanding the evolutionary biology of genomes. A coordinating committee then revi...

Secrets of the cilia: Kidney disease and blindness share common genetic defect

...PHP1, NPHP2, and NPHP3, mutated forms of which are responsible for three types of nephronophthisis. In 2002, they discovered a fourth gene, NPHP4, simultaneously with another research team in France. The most recently discovered gene, NPHP5, accounts for a small percentage of nephronophthisis cases, but it plays...

...ontin plays a central role in a feedback mechanism responsible for amplifying RA. The study increases our understanding of the role of osteopontin in inflammatory process in general and in the development of novel therapeutic strategies for RA and other inflammatory conditions. TITLE: Role of osteopontin in amp...

Researchers make surprise discovery that some neurons can transmit three signals at once

...unication network of brain cells, or neurons, each responsible for relaying one specific chemical message called a neurotransmitter. Either neurons release a neurotransmitter that excites a neighboring cell, thereby triggering an electrical discharge and enhancing brain activity, or they dispatch a signal that q...

Basis for DNA ejection from single phage particles

...uring packaging of the DNA in the phage capsid was responsible for DNA ejection. This pressure results from the condensation of the DNA during morphogenesis for example, another group recently showed that the pressure at the final stage of encapsulation for a particular bacteriophage reached a value of 60 atomo...

Genetic therapy reverses nervous system damage in animal model of inherited human disease

... "Through gene therapy, we replace a 'broken' gene responsible for alpha-mannosidase with the correct, functioning copy, to dramatic results," said John H. Wolfe, a professor of pathology and medical genetics at the Penn School of Veterinary Medicine and a neurology researcher at Children's Hospital. "The treat...

New class of tuberculosis-fighting antibiotics suggested by biochemical-pathway study

...p in a common biochemical pathway. This pathway is responsible for making the energy molecules all cells need to survive. First author Edward Weinstein, an MD/PhD student, Rubin, and colleagues characterized the pathway and showed that an important enzyme in it is a key target for anti-TB agents. The pathway, ex...

Gene variation could be responsible for age-related macular degeneration

...ital of Dallas. "Once we determine which genes are responsible for macular degeneration, we can screen the population and manipulate biological pathways to develop treatments." Also involved in the study were researchers from Boston University School of Medicine and Sequenom, Inc....

Gene variant increases risk of age-related macular degeneration

... researchers estimated that the CFH variant may be responsible for up to 43 percent of all cases of AMD. Earlier studies had suggested that CFH may play a role in protecting blood vessels from inflammation and damage, a function which might explain its role in AMD, the researchers said. "We knew that chronic i...

Researchers report new pro-inflammatory role for anti-inflammatory enzyme

... inducible nitric oxide synthase (iNOS), an enzyme responsible for the manufacture of nitric oxide (NO). This results in an increase in cellular NO which contributes to inflammation and host defense. "NO acts as a cytotoxic/cytostatic effector molecule released (predominantly) by immune cells," explains Dr. Adr...

Discovery may lead to better Candidiasis drug

...lls the oral pathogen Candida albicans, the fungus responsible for most HIV-related oral infections. Researchers led by Mira Edgerton, D.D.S., Ph.D., discovered that histatin binds to a specific membrane protein called TRK1p, which regulates potassium ion flow through the cell membrane of the pathogenic fungus ...

Chemical engineer Kao explores antibiotic synthesis with DNA chips

... similar study by Kao's group identified two genes responsible for overproduction of the antibiotic tylosin. Instead of increasing the length of time that a bacterium produces the antibiotic--the case with erythromycin--these two genes allow the bacterium to produce it faster. Again, the specific mutations elude...

Using molecular technique, researcher identify hospital pool bacterial pathogen

They found: when the bubble bursts, the bacteria disperse, and lifeguards get pneumonia-like symptoms. Lars Angenent, Ph.D., Washington University assistant professor of chemic...

Light therapy may combat fungal infections, new evidence suggests

...ormans. The Duke team has now identified two genes responsible for that light response. Loss of the same genes also reduces fungal virulence in mice, they reported. Earlier studies had linked the genes to light-sensing in another distantly related fungal lineage, an indication that the fungal light sensor arose ...

Determining the fate of cells in the human body

...Medicine, investigated the interaction of proteins responsible for Saethre-Chotzen Syndrome, a rare genetic disorder associated with limb abnormalities including webbed fingers and other developmental defects. In the study, Dr. Firulli and colleagues studied how two proteins, Twist1 and Hand2, which are antagoni...
