Reversal of role for a viral protein associated with the development of lymphoma

...ic advantages for large introns," Lopez said. "One possibility is that recursive splicing prevents the generation of long RNA transcripts that could form structures that interfere with correct processing into mRNA. Another is that recursive splicing might help stimulate transcription through long introns by prom...

Public collections of DNA and RNA sequence reach 100 gigabases

... genetic code, several groups began to explore the possibility of developing a public repository for sequence information. In the early 1980s this led to the launch of two databases: the first was the EMBL Data Library, based at the European Molecular Biology Laboratory [EMBL] in Heidelberg, Germany [the Data Li...

Virologist finds contagious equine flu in dogs

...r equine influenza virus. Donis also ruled out the possibility that the sample had been contaminated with equine virus from another source. ...

Discovering an ecosystem beneath a collapsed Antarctic ice shelf

...never knew was there." Domack suggests the strong possibility that new species of marine life may be uncovered in continuing analyses of the area as ecosystem experts sample the site. The international expedition was there on a U.S. Antarctic Program cruise to study the sediment record in the area vacated by th...

U of MN researchers reverse memory loss in mice

...at shows how the disease progresses as well as the possibility that memory loss can be reversed. The research suggests that the same reversal may be possible in humans, and that people with Alzheimer's disease may be able to recover memory and improve in cognitive function if they can halt progression of the dis...

Nose odors and mouth odors: The brain distinguishes

Treatments have same target, different responses for lung cancer patients with genetic mutation

...d to cetuximab. "Overall, our results raise the possibility that NSCLC patients with EGFR mutations may derive the greatest benefit, in terms of tumor regression, if treated with gefitinib rather than with cetuximab," the authors conclude. "These findings clearly have important clinical implications becaus...

Brain size may depend upon how neural cells are cleaved

... the plane of division," said Tsai. "And with the possibility that neural stem cells may find therapeutic use, the role of G protein signaling in the differentiation of such progenitor cells is going to be a very exciting area to explore," she said. ...

One bacteria stops another on contact

...etition in the environments they grow in. "Another possibility is that the bacteria use the CDI system to shut themselves off inside a host, going into a dormant state where they may go undetected by the immune system," he said. Thousands of women in this country have chronic urinary tract infections, noted the...

Unweaving amyloid fibers to solve prion puzzles

...he core of nanoscale electrical wires, opening the possibility of one day incorporating them into integrated circuits. "These findings are quite relevant for the material sciences," says Lindquist. "The more we understand about how these fibers work, the more we can get them to self-assemble," a key advantage f...

The very defensive caterpillar

...to such control agents but these results raise the possibility that control with one pathogen may confer resistance to another. Most experiments on insect immunity are conducted in the laboratory on insects often fed on antibiotic containing diet so these results suggest that the immune response of insect consta...

Ancient DNA confirms single origin of Malagasy primates

...ted taxonomic success of our study leaves open the possibility that data from additional taxa will overturn this increasingly robust hypothesis." Yoder said the researchers' results support the close relationship of sloth lemurs (Palaeopropithecus) to living indriids, but Megaladapis does not show a sister-grou...

Mosquito study shows new, faster way West Nile can spread

...he spread of West Nile virus take into account the possibility that mammals such as horses may be involved in the proliferation of this virus. Direct transfer of virus from the infected mosquitoes that initially feed on them to others that feed on them afterwards, could significantly accelerate the spread of the...

Clearing jams in copy machinery

...for how the polymerase switch is controlled. "One possibility is that the beta clamp may sense when Pol III stalls, triggering a change in beta that pulls the polymerase from the primed site, allowing Pol IV to take over synthesis," O'Donnell says. Or, Pol III, upon stalling, may loosen its grip on the templat...

Learning how SARS spikes its quarry

...change, it gives you an opportunity to explore the possibility of antiviral therapeutics," said Harrison. "When you have two conformational structures, you can think about how to prevent infection by inhibiting the transition from one state to another." ...

Plants discriminate between self and non self

...genetically it was identical. "This eliminated the possibility that the mechanism was based on specific chemical recognition," says Falik. "The results prove that at least in the studied plants, self/non-self root discrimination is based on physiological coordination between roots belonging to the same plant. Su...

OHSU researchers discover potential mechanism to repair brain damage linked to Multiple Sclerosis

...t for therapies and opens the door to the exciting possibility that we may, one day, be able to not only stop disease progression but also repair damage that is already there. The future efforts of our three labs will be aimed at exactly that goal. " "The work of these investigators offers new hope to people wi...

Molecular Partners Required For Appropriate Neuronal Gene Repression

Human brain is still evolving

...may relate to cognition, Lahn emphasized that this possibility remains speculative. "What we can say is that our findings provide evidence that the human brain, the most important organ that distinguishes our species, is evolutionarily plastic," he said. Finding evidence of selection in two such genes is mutuall...
