The sequencing of the bovine genome will also help medical researchers l...Genetics play role in response to most common asthma drug
...ild asthma. The trial paired 78 participants with matching levels of airway function but with different forms of the receptor gene. Researchers compared participants who have two arginine versions of the gene (the arginine genotype) to those with two glycine versions of the gene (the glycine genotype).

...ll. He explains that if cells between species have matching molecular fingerprints, then the cells are very likely to share a common ancestor cell. Scientist Kristin Tessmar-Raible provided the crucial evidence to support Arendt's hypothesis. With the help of EMBL researcher Heidi Snyman, she determined the m...Cell enzyme may help suppress cancer development

Fifty-one percent of the tumor samples were heavily methylated, while the gene in the adjacent normal tissue was essentially methylation-free.

...how extensively the sediments are mixed there, and matching that with data on each species' size, abundance and movement through the mud, it is possible to construct mathematical models to predict the ecological consequences of losing species, according to Cardinale. Running the models, the group found ...NIH makes award to UNC for Genome Fingerprint Scanning program
...rrect. By contrast, the GFS program is capable of matching mass spectrometry data from proteomic studies directly to raw, or even unfinished, genome sequences. The program has already been used to identify novel proteins in Francisella tularensis, the bacterium that causes the infectious disease tularemia, ...Spider silks, the ecological materials of tomorrow?
... The outcomes have been promising but are far from matching naturally produced silks. For the moment the fibers produced are too wide, with diameters ranging from 10 to 60mm, compared with diameters of 2.5 to 4.0mm in natural fibers....How the brain is wired for faces

...somewhat expensive process. Other methods, such as matching the pieces to their compliments on microarrays, are limited by the size of genome they can analyze. Dunn's team has come up with a technique to determine the positions of these 500-to-1,500-base-long pieces on an entire genome -- even one as large as...DNA movement linked to formation of antibody genes

...f DNA cut out of chromosomes during the mixing and matching of genes that are chosen to build a particular receptor. Each T cell uses the resulting combination of genes to make a receptor that lets the cell recognize a specific target. When stimulated to multiply, each of those cells produce an army of immune...New RNA polymerase discovered in plants

And finally, SCID may be treated through human gene therapy in which a normal copy of the defective gene may be inserted into the patient's own blood-forming cells.

...ound, and there is a lot of commercial interest in matching nematodes to pests, Stock says. "Yet these nematodes are so powerful and pathogenic not in and of themselves, but because they live in symbiosis with bacteria," Stock concludes. "Both the bacteria and the nematode need each other to survive, making t...Researchers identify gene that plays major role in age-related blindness disease

...lion letters of the human genome should find those matching sequences. But this didn't work. The homology searches yielded far fewer targets than expected and could not account for all known microRNAs. The reason, says Han, is that scientists were trying to predict the microRNA targets using the sequence hom...Silence the gene, save the cell: RNA interference as promising therapy for ALS
