Gut protein found to protect against infection and intestinal breakdown

...e liver damage, Dr. Kliewer said. The researchers focused on a molecule ?FXR ?in the wall of the lining, which binds to bile acids. When FXR was activated by a synthetic binding chemical called GW4064, it was found to activate several genes that are known to protect the intestinal lining or attack bacteria....

MIT research holds promise for Huntington's treatment

...searchers looking for Huntington's treatments have focused on compounds that prevent or reverse the aggregation of huntingtin proteins. However, recent evidence suggests that the largest inclusions may not necessarily be harmful and could in fact be protective, said Bodner. So, the MIT and Harvard scientists...

Paleontologists learn how not to become a fossil

...ost reliable data," she said. The PNAS co-authors focused on bivalves (clams, scallops, oysters, cockles and their kin), because they serve paleontologists the way geneticists use mice or fruit flies as model systems. Jablonski called the clam "a real bellweather" for understanding many long-term changes in...

Invasive exotic plants helped by natural enemies

...ssments of this "natural enemies hypothesis," have focused on the effect that specialized insects have on plants. However, Parker notes that insects commonly reduce plant growth and biomass, but vertebrate herbivores are often larger and thus more commonly kill plants outright. Because of this, vertebrate he...

For the first time: Longevity modulated without disrupting life-sustaining function

... 20 to 40 days. Except the worms trade a trim life focused on reproduction for a long life with fewer progeny and a tendency to halt larval development and enter a dormant, hibernation-like stage in which they can hang on for months but don't reproduce. Unless Smk-1 is missing, that is. Without Smk-1 to p...

Bone and cartilage growth to blame for heart valve disease

...t up on the valves. Therefore, research has never focused on preventing the problem," says Dr. Rajamannan. ...t of people who have symptoms. Dr. Rajamannan has focused her research for the past seven years on advancing the knowledge of mechanisms of aortic and mitral ...

Not just the birds

... islands," say the authors. Previous studies have focused on trophic cascades in marine ecosystems, showing that top predators can indirectly alter plant productivity, with varying effects. Most studies on land-based ecosystems have been smaller in scale. These studies have not revealed the large communit...

Most human-chimp differences due to gene regulation ?not genes

...e adult males from each of the four species. They focused their search on expression levels of two sets of genes, those that remained largely unchanged across all four species, suggesting that there was little room -- or need -- for improvement, and those that changed most dramatically, usually in the human...

Tandem transcripts team together

...nome survey of splicing events, Guigó's laboratory focused on the ENCODE regions, a set of DNA sequences, representing 1% of the genome, that have been chosen by a large research consortium for more rigorous, in-depth analyses. When focusing on these regions, the researchers identified six TIC events (invol...

Gene variation increases SIDS risk in African Americans

...dults with no known health problems. Their search focused on abnormalities in a gene called SCN5A, which has been associated with abnormal heart rhythms. Overall, the team found common and rare changes in this gene in five percent of SIDS deaths in African Americans. One specific variation, known as Y1103,...

One fish, two fish: New MIT sensor improves fish counts

...st along the continental shelf, so the researchers focused their attention on the waters south of Long Island, New York. When they first started, they weren't looking for fish at all - they wanted to see if their device could locate ancient riverbeds under the ocean floor. But when their reconnaissance image...

Study may help slay 'Yellow Monster'

...e such partnerships in the nation and the only one focused on Native American issues. "The data on Native Americans for cancer evidence is very poor," Stearns said. "Navajo and Hopi may not get cancer to a greater extent, but the survival rate is lower than the general population." Stearns said the lower su...

Inflammation and drugs to control this activity studied in a variety of tumors sites

...or developing such high-grade tumors. He and Bondy focused on antihistamines because people who have allergies typically take antihistamines. "We knew that the different types of tumors have different etiologies and different genetic characteristics and we wanted to see if there were differences in risk," B...

APS lecturer shows rare video of 'teacher-student' immune cell interactions in live animal

Mayo Clinic researchers discover cancer cells may move via wave stimulation

Until now, no one has fully understood the function of these waves. The Mayo findings in the current edition of Cancer Research http://cancerres.aacr...

Value of services performed by insects tops $57 billion in US

... insects, Vaughan said. Losey and Vaughan's study focused on the economic value of four particular services -wildlife nutrition, pest control, pollination and dung burial - selected because robust data were available for an analysis. "A lot of value is added to the economy by insects, but most people just ...

Pigeons provide clue to solving common problem in heart patients

... vessel tissue-building process, so Wagner's group focused on "transcription factors," which regulate whether a gene is expressed and at what rate. The group's aim was to see if certain transcription factors might be found in altered amounts in the smooth muscle cells of pigeons that are prone to atheroscler...
