Bioinformatics reveals new gene regulation system

...kwards ?a common feature of DNA sequences that are recognized by regulatory molecules. They designated the sequence the NrdR-box. Because the signal was found in so many diverse groups of bacteria, the researchers thought it might represent a universal regulatory mechanism. The next question was whether the si...

Where Bacteria Get Their Genes

...sfer, unique to the bacterial world, has long been recognized as common. But until now scientists did not know which of a bacterium's genes came from lateral gene transfer and which had been inherited from its parent. In their study, the scientists focused on the best-studied group of bacteria, the Gamma-Prote...

Scientists discover global pattern of big fish diversity in open oceans

... though space and time. It reveals that some areas recognized today as good fishing are perhaps even more important than we realize ?which makes it all the more urgent to protect these last remaining bits, say the authors. Today the east coast of the U.S., just south of Cape Hatteras and along the east coast o...

Tamoxifen-like drug suggests new ways to selectively block estrogen

...llcome, hence the name GW5638. McDonnell, at Duke, recognized its potential and demonstrated efficacy in animal models of tamoxifen-resistant breast cancer. The drug has completed initial phase I clinical testing and has garnered significant interest from the pharmaceutical industry. ...

New vaccine means bye-bye to bacteria in the lung

...aeruginosa, called OprF, which had previously been recognized as a promising vaccine candidate. This region of the bacteria was expressed in the capsid area of the vector. Immunization of mice with this vaccine induced antibody production and protected the mice from exposure to a deadly dose of the bacteria. Im...

Alien woodwasp, threat to US pine trees, found in N.Y.

... stumbled across the specimen of S. noctilio . "I recognized it immediately," says Hoebeke, a taxonomic expert who has examined tens of thousands of insects sent to him from agencies and scholars over the past 25 years. "I'm always on the lookout for exotics -- for any species that are not yet established in t...

Second messenger NAADP shows fast, dose-related impact on satiety cycle

...e notes, Viagra is the world's most successful and recognized secondary messenger targeting drug to reach the market. Cholecystokinin, a first messenger, activates NAADP; so which is 'therapeutic?' Several earlier drugs designed for obesity treatment were chosen because they released a chemical ?the hormone s...

Disabling gene defuses rheumatoid arthritis in mice

Some Brain Cells Change Channels

...hough the cells' channel-changing ability has been recognized for a few years, the key players controlling it hadn't been identified. Now, by studying mice, the Hopkins team has identified two proteins, called PICK1 and NSF for short, that help replace channels that let charged calcium ions in with another kind...

Researchers test new therapy for advanced melanoma

...es the immune system formed a memory response that recognized the melanoma cells as foreign and prevented tumor regrowth. "We were very encouraged by the results of the preclinical studies." Dr. Heller said. "We're hoping this translates into a beneficial treatment for patients." The Phase 1 clinical trial by...

Embryonic Stem Cells Treated With Growth Factor Reverse Hemophilia In Mice: UNC Researchers

...lls robustly engraft within the liver and were not recognized by the immune system as foreign. "Within a few weeks, PEPs became hepatocytes," Fair added. "They went from something that is a very early grandparent of the hepatocyte to becoming hepatocytes. After 115 days, nearly four months after injection, mic...
