Boffin Identifies Gene Causing Otosclerosis

A new study has identified a gene responsible for otosclerosis - the single most com...the genetic components has been identified. "The gene in which the variant is located points to a pathway that contributes to the disease. This may be a l...

Genome Annotation by Mutation

... Capecchi says. Capecchi is known for developing gene targeting, in which mice are bred with a gene disabled or knocked out to see what goes wrong, thus revealing the genes normal function and how dis...

Boffins Develop New Technique to Hunt Illness-causing Mutants in Non-gene DNA

...that technology is very good at changing any given gene in a designed manner. The negative side is, it tak...The new method is "a cheaper way of knocking out a gene as well as regulatory sequences," he adds. He, however, admits that the savings are not proportionat...

Genetic Variations Leads to Fever After Smallpox Vaccination

...he research team found that variations in the IL-1 gene complex on chromosome 2 were most closely linked t...n. Additionally, several variations in the IL-18 gene on chromosome 11 increased fever risk, while one decreased the likelihood of fever. That gene is inv...

Parkinsons Disease Protein Pathway Identified

...n disease to mutations in both copies of the PINK1 gene (one from each parent). They also have evidence that single-copy mutations in PINK1 are a significant risk factor for the development of later-onset Parkinson disease. "We now know much more about the effect of PINK1 mutations on the mitochondria a...

Weizmann Researchers Developed Control Switch for Protein Activity

... In addition, the method could be used one day in gene therapy. It may be possible to replace damaged proteins that cause severe diseases with genetically engineered proteins, and to control these proteins activity levels in a precise manner by giving appropriate doses of the drug. Another potential futu...

Genetic Tests Could Help Decide the Right Anti-depressants

...rted into a mouse a defective variant of the human gene for brain-derived neurotrophic factor, a protein that is increased in the brain with SSRI treatment and is critical to the health of neurons. Then he subjected these humanized mice to stress and found that they did not respond to Prozac with decrease...

Key Signaling Molecules in New Teeth Formation Identified

...e mutant analyses , organ culture experiments, and gene expression studies, although mammals have a limited capacity to regenerate teeth, mouse incisors contain stem cells and grow continuously throughout life. The researchers show that signals from the adjacent mesenchymal tissue regulate epithelial st...

Women With Few Older Female Relatives Face Cancer Threat

Protein Pathway Involved in Parkinson Disease Development Identified

... in both copies of the mitochondrial protein PINK1 gene (one from each parent) that normally protects cells from oxidative stress and promotes cell survival by regulating function of the protein TRAP1. The Emory researchers found that when PINK1 is mutated, however, the protective TRAP1 pathway is disru...

Of these, 10 turned out to affect the prostaglandin pathway: five increased the formation of blood stem cells, and five decreased it. We werent specifically looking for prostaglandins, says Zon, a Howard Hughes Medical Institute investigato...
