A new mechanism of regulating RNA degradation

...s a well-known RNA binding protein and some of its functions in the common fruit fly Drosophila are understood. "But no one knew what Staufen1 did in human cells," said Maquat, even though its presence in mammalian cells has been recognized for several years. "We were surprised to find that Staufen1 interacts...

Scientists seek answers on what activates deadly anthrax spores

...exploring the three-dimensional structures and the functions of the proteins involved. State-of-the-art facilities at the Center for Structural Biology will be used to determine how genetic information in the anthrax chromosome translates into a vast array of protein structures, Claiborne said. Once they know ...

Gene therapy converts dead bone graft to new, living tissue

... If calcium, which is necessary for such important functions as maintaining the brain and heart, runs low, cells called osteoclasts dig out the calcium from our bones. This is why doctors encourage post-menopausal women to take calcium supplements, so that the body doesn't raid their bones for the calcium it n...

Essential mangrove forest threatened by cryptic ecological degradation

...lationships, lagoon fisheries, and many additional functions provided by mangroves. The authors believe that the worrying aspect of the research is that a degradation of the most vulnerable, most socio-economically important and most aesthetic species is masked by the expansion of less important species. The ...

U-M scientists find genes that control growth of common skin cancer

...igan and the NationalCancer Institute examined the functions of the Hedgehog (Hh) signalingpathway in basal cell carcinoma ?the most common form of cancer ?anduncovered a subset of tumor cells that were resistant to inhibition ofthe Hedgehog pathway. The new finding has important implications forthe treatment ...

New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

... two critical and exciting questions: What are the functions of these previously unannotated transcripts and what are the regulation schemes that orchestrate such complex assemblies of transcription? It seems certain that this is not the genome we learned about while in school." In the "traditional" view of t...

Highly adaptable genome in gut bacterium key to intestinal health

...ng nutrient conditions but also helps maintain the functions and stability of the gut's highly complex microbial society, according to researchers at Washington University School of Medicine in St. Louis. Their findings are reported in the March 25, 2005 issue of the journal Science. "Bacterial cells in the ...

DNA Recombination and Repair—A New Twist to RecA Function

...e and organize their activities to carry out these functions has remained obscure. Cox et al. addressed this problem in the test tube, by examining RecA filaments grown from mixing RecA protein with DNA. Previous experiments have shown that filament assembly spreads rapidly in the 5'-to-3' direction once the ...

RNA project to create language for scientists worldwide

...scovery of new RNA molecules with novel biological functions is beginning to show that RNA plays far more roles than originally believed. For instance, while genomicists had previously determined that humans and chimpanzees share 99 percent of the same protein genes, it has now been discovered in the past two ...
