Sudden change in social status triggers genetic response in male fish, study finds

...Our study shows that the male cichlid is obviously interacting with the world around it," says Burmeister, a former postdoctoral fellow in the Fernald lab, now assistant professor of biology at the University of North Carolina-Chapel Hill. "The subordinate male is responding to the absence of another individual,...

Flip-flopped chromosome reveals a first clue to Tourette syndrome

...d to be involved in regulating SLITRK1 activity by interacting with molecules called microRNAs. In further studies, the researchers found that a specific microRNA that regulates SLITRK1 binds to the genetic site of variant 321. They also found that SLITRK1 and the regulatory microRNA are both expressed in region...

Electrical engineer works on personalizing medical treatment

... cell can contain one billion molecules capable of interacting with each other. These numbers produce "vast amounts of data that need to be interpreted and analyzed so that the components involved with diseases can be isolated and identified," Wang explains. This data processing and manipulation typically falls ...

New Columbia University center aims to advance next generation of genomics, proteomics research

...s of systems biology to predict which proteins are interacting with each other and with DNA, and how these interactions change in disease. Eventually, this will have a major impact on how we understand a variety of human diseases, including cancer." C2B2 MAGNet will be housed on the Columbia University Medical...

Hebrew U. / Johns Hopkins study provides clues to dealing with human disease

...ng with removal of the worm's lamin protein or its interacting protein partners emerin, MAN1 or BAF, the researchers have described "down-the-line" consequences, including the disruption of various proteins necessary for normal cell reproduction. Even though the C. elegans worm has only one lamin protein and few...

Spiders help scientists discover how muscles relax

...e heads of each myosin molecule are inhibited from interacting with actin by interacting with each other instead. When muscle is activated, they suggest, the bonds between the myosin heads ...

UCLA researchers identify key enzyme linked to childhood blindness

...sely with Rpe65. Mutations in the genes for these interacting proteins are linked to other forms of human blindness. "These results settle the long standing mystery about the identity of the retinoid isomerase," Travis said. "Scientists have been searching for this enzyme for almost 20 years. Our results also e...

New DOE program funds $20 million for multiscale mathematics research

...x physical processes that occur on a wide range of interacting length and time scales. The current state-of-the-art in the theory and modeling of complex physical systems generally requires that the physical phenomena being modeled either occur at a single scale, or widely separated scales with little or no int...

Random gene expression may drive HIV into hiding

... Commonly, it's only when just a few molecules are interacting with each other that random fluctuations can have such a large effect on eventual outcome, he explained. The researchers hope that understanding the molecular basis of HIV latency will lead to new treatments to slow or stop progression to AIDS. For e...

Critical step traced in anthrax infection

...channel. The clamp appears to work as a chaperone, interacting with the hydrophobic sequences on the two factors as they unfold during translocation. The researchers demonstrated that the phi-clamp was critical to infection by mutating the region and thereby blocking translocation of the toxin proteins. These r...

Primate virus jumps species barrier to humans for first time in Asia

...hey do urge people to be cautious and careful when interacting with monkeys. Feeding the animals, or even carrying food into a temple, can greatly increase the risk of a bite or scratch, which can lead to transmission of infection. Visitors occasionally engage in other risky behavior, such as touching animals or...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

...irst author Kurt Krummel. "You have to look at all interacting partners because after all, modifications of p53 itself might not be so important as modifications of negative regulators and co-activators." Many chemotherapeutical drugs used to treat cancer exert their biological effects on tumor cells through a...

...-protein interactions because the distance between interacting proteins could be controlled with nanometer accuracy," said Yan. Also, by attaching different proteins onto the DNA scaffold, Yan could directly visualize the binding of a drug to its target molecule or recreate metabolic pathways on a single array ...

Inner structure of cells behaves much as molten glass

... This is a collective phenomenon of many molecules interacting in concert, and would disappear altogether in the study of one molecule interacting with another in isolation," said Fredberg. He continued, "The laws governing cell behavior bring tog...

UQ among world leaders in schizophrenia research

...zophrenia is likely to be the result of many genes interacting with each other and with environmental risk factors." Dr Mowry said identifying and understanding these genes may lead to better drug treatment. "Around 70 percent of people with schizophrenia respond to medication but current drugs have some unple...
