U of MN researchers reverse memory loss in mice

...ssly around the pool would again concentrate their search on the area of the pool where the platform was located, thus showing memory recovery. Researchers from the Department of Neuroscience at Mayo Clinic Jacksonville, and the Department of Neurology at Massachusetts General Hospital contributed to the s...

MicroRNA tweaks protein that controls early heart development

...targets in mammals. He then used those criteria to search the entire mouse genome for potential microRNA targets. "If this method of predicting targets turns out to be correct and specific, I think it will go a long way to opening the field more broadly, providing scientists who study microRNAs with an eas...

Mass production of human papillomavirus could lead to gains against cervical cancer

...que to study the early process of infection and to search for vulnerabilities in that process, said Ahlquist. "The early stages of infection -- before the virus becomes established -- could be a very important phase for intervention," he said. Ahlquist also said that the production technique could offer a ...

Scientists at Galileo Pharmaceuticals confirm inflammatory response linked to glucose levels

Can our genes tell the story of our divergence?

...gy. One way to find such genetic signatures is to search for genes that reveal signs of positive natural selection. The assumption is that genes touched by positive selection will show more functionally significant molecular changes than unaffected regions. In the new study, Rasmus Nielsen, Michele Cargill...

New tool reveals secrets of migrating cells

... outer layer, or cortex, of the thymus, perhaps in search of that life-altering signal. Robey hopes to use ... Witt, suggest that this exploration probably is a search for a signal that will decide the cell's fate. In their experiments on one lobe of the mouse thymus,...

Newly discovered genetic disease sheds light on body's water balance

...blood samples from each baby boy and his mother to search for the cause of the unique disorder. They learned that Raymond Fenwick, a scientist with Quest Diagnostics Nichols Institute, was developing an assay that could be used to sequence the AVPR2 gene that codes for the V2 receptor. Fenwick sequenced th...

Researcher gets NSF grant to create mutant maize lines

...d library that allows researchers to do a database search for a DNA sequence and identify a single line of maize with a single disruption in the genome," says Brutnell, who notes that the project could expand the understanding of the functions of about 20 percent of the maize plant's entire genome. Once sc...

Achilles heel of the herpes virus possibly found

...tein for entry into cells." She explains that the search for the mechanisms by which HSV enters cells has been hindered by the fact that the virus is very good at entering so many kinds of cells. The many possibilities for virus binding to cells make deciphering the entry process a difficult problem to sol...

Bioinformatics reveals new gene regulation system

Improved statistical tools reveal many linked loci

...method can be applied to more complex organisms to search for even larger numbers of linked loci and to provide insights into the many interlocking pathways that make up the gene regulatory network. Citation: Storey JD, Akey JM, Kruglyak L (2005) Multiple locus linkage analysis of genomewide expression in ...

MicroRNAs play a big part in gene regulation - and evolution

...l Genomics tapped into the power of computation to search for microRNAs and their target genes in the entire genomes of seven Drosophila species. The authors then compared identified matches to matches they had found previously in vertebrates. The results provide the most extensive microRNA target gene pre...

High-powered gene profiles provide clues to genes involved in common form of lung cancer

...logical advances have brought new precision to the search for gene abnormalities associated with cancer. In ...ons, respectively. This enabled them to narrow the search for genes that were the targets of the irregular regions. Intriguingly, all of the genes already kno...

Natural tumor suppressor in body discovered by UCSD medical researchers

...off" position. The scientists conducted a database search of the human genome for a phosphatase, which is an enzyme that acts as a catalyst in regulating cellular processes by removing phosphate molecules. Based on the chemical components of Akt, they specifically looked for a phosphatase linked to the PH d...

In New Orleans, as the swirling, airborne masses of termites become more conspicuous, researchers with the Agricultural Research Service (ARS) are busy developing a biopesticide that could someday knock down large number...

Insects, viruses could hold key for better human teamwork in disasters
