Identification of specific genes predicts which patients will respond to Hepatitis C treatment

...tment. He is now clear of the virus. "Knowing that you are a responder gives you the courage and the fight to go on. It was devastating, but having the support of my friends and hos...

Researchers feed tiny pills of RNA to planarians to identify genes essential for regeneration

...ian biology has much in common to the biology that you and I share," said Sánchez Alvarado, who last month was appointed a Howard Hughes Medical Institute investigator. "This work opens a whole new window to study aspects of human biology that are barely accessible today." The planarians used in these s...

Study shows how retinoic acid enters a cell's nucleus

...ed to the toxic doses currently administered. "If you can provide a bus to get retinoic acid into the nucleus more efficiently, then you enhance its ability to act as an anti-carcinogen," says Noy. "It's a rapid transport advantage." He...

Gene expands malaria's invasion options

Say what? Bacterial conversation stoppers

...associate with humans," Bassler said. "In the gut, you can imagine how the normal microflora might interfere with cell-cell communication to thwart bacterial invaders." Using a chemical communication process called quorum sensing, bacteria converse among themselves to count their numbers and to get the...

Micro-molecule plays big role in birth defects

...ncer to AIDS. "There is indirect evidence that if you remove two microRNAs from the human genome, leukemia develops," Harfe said. "We envision our mouse model may be a tool to directly test how microRNAs are involved in human cancers." ...

Gene therapy advance treats hemophilia in mouse models

...didate for correction with gene therapy because if you could just raise the factor VIII activity from less than 1 percent of normal to within 5 to 10 percent of normal, the tendency for spontaneous bleeding and need for hospitalization would diminish dramatically," McCray said. "In the mouse model in o...

New Scripps Oceanography project to study sediments and ecosystem restoration in Venice lagoon

...ries back in time. Because the sediment is so old, you could expect metals and organic contaminants to be present," said Deheyn, whose experience includes using biological indicators to test for toxins and pollutants in San Diego Bay. As in San Diego's waters, when studying Venice's lagoon Deheyn will u...

Virologist finds contagious equine flu in dogs

..."With 50 million pet dogs in this country, even if you have 1 percent mortality, this is going to result in a number of dogs dying from it." The Centers for Disease Control and Prevention (CDC) in Atlanta sequenced the virus' entire genome and found all the segments were from the equine virus. This is...

Slipping past the blood brain barrier: Research shows potential treatment for brain cancer

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 Progra...
