Carnegie Mellon University research reveals how cells process large genes

... 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 promoting interactions between the splic...

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

...yellow fever virus have a protein called NS4B that prevents interferon from functioning properly. It was thoug...therapies, but the RML work shows otherwise. "NS5 prevents interferon from doing its sentry job and allows the virus to take over cells," says Dr. Bloom. "This...

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

Secrets to antibody's success against West Nile Virus surprise scientists

...ntists found evidence suggesting that the antibody prevents the virus from rearranging the protein envelope that surrounds its genetic material after it enters a host cell. To reproduce, a virus must alter its envelope in order to inject its genetic material inside the cell. After that injection, the virus...

Discovery of T-cell 'traffic control' boosts new drug promise

... called S1P and its receptor on T cells -- usually prevents T cells from launching harmful reactions. But when the S1P traffic cop reacts incorrectly, T cells can swamp healthy tissue. The new research explains how a promising experimental drug treats the autoimmune disease multiple sclerosis by blocking exce...

How cell suicide protects plants from infection

...a zone of dead cells around an infection site that prevents the infection from spreading. Savithramma Dinesh-Kumar, associate professor of Molecular, Cellular and Developmental Biology at Yale and his colleagues discovered how the plants keep from killing themselves after they turn on the cell-suicide PCD pro...

Once given 'no respect,' cells' tiny RNAS take driver's seat

...rence -- a biological phenomenon that specifically prevents RNA from being used to make proteins. Accompanying the Hopkins paper are two reports looking specifically at microRNAs in cancer -- one in humans, one in mice. One report shows that human tumors' microRNA "fingerprints" -- patterns showing which of ...

Hanging baskets of sex and death help fruit growers

Suppressing growth hormone in early adulthood may prevent cancer

... blood-borne factor that increases cell growth and prevents cell death and has been proposed to be a factor in the initiation of cancer. "Elevated IGF-1 levels in pre-menopausal women have been demonstrated to be a risk factor for breast cancer as well as numerous other cancers," said Sonntag, professor of p...

Virus uses tiny RNA to evade the immune system

...h larger messenger RNAs (mRNAs). That interference prevents mRNAs from making proteins. Scientists do not know which genes are hushed by the microRNAs in people, but the new study bolsters growing evidence that the little molecules can play important roles not only in normal human cells but in infected cells ...

New antibody shows promise as cure for anthrax

The other looks to innate immunity, theorizing that since the high-affinity antibody clears the body of the deadly toxin, it allows the body's initial immune response to successfully kill the anthrax bacteria on its own. ...
