A new mechanism of regulating RNA degradation

... Upf1 and Staufen1 can be phosphorylated, so their activities could be regulated by cell signaling pathways, such as those mediated by changes in growth conditions." That would allow the cell to differentially control the level of SMD-target RNAs, while leaving the NMD-regulated RNAs untouched. This is likely ...

FDA Approves Human Hookworm Vaccine for Phase I Safety Trials

... Upf1 and Staufen1 can be phosphorylated, so their activities could be regulated by cell signaling pathways, such as those mediated by changes in growth conditions."

The secret lives of whales

...tracking how whales move away or go quiet as human activities enter an area. Every decade the amount of noise is doubling. “Whales have very traditional feeding grounds and their migratory routes along coastlines have become incredibly noisy, urbanized habitats,?Clark explains. “Acoustic smog is shrinking their...

Gene therapy converts dead bone graft to new, living tissue

...however, when the bone wears over time. "Everyday activities cause microscopic fractures in our bones," explains Schwarz. "Those fractures are normal and healthy, and our bones re-knit them constantly. But when the bone is dead, there is no healing, and those tiny fractures begin to accumulate until finally, p...

DNA Recombination and Repair—A New Twist to RecA Function

...es within a filament coordinate 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...

South America's vast pantanal wetland may become next everglades, UNU experts warn

Artifical cornea lets woman blind 20 years see

...upon family and friends to help her do many of the activities people with normal vision sometimes take for granted. Now, twenty years and several life milestones later, Elma is able to see again, thanks to advances in ophthalmology research. Physicians at Duke University Eye Center and Harvard have been monito...

Potential treatments for neurofibromatosis

...lf," said Dr. Clapp. That's because the biological activities of non-malignant cells are stable, while malignant cells are constantly changing due to the genetic instability common to tumors. By using drugs that target the mast cells' ability to promote blood vessel growth, Clapp and his colleagues hope to pre...

How the environment could be damaging men's reproductive health

...ontamination for POPs are closely related to human activities such as domestic and industrial discharge, automobile exhausts, street run-off, slum sewage and agricultural chemicals. POPs from polluted soils are washed off the land into the sea. Additionally, the atmosphere plays an important role in their trans...

UCLA launches $20 million stem cell institute to investigate HIV, cancer and neurological disorders

...ged in adult and embryonic stem cell research with activities in areas ranging from the AIDS Institute to the Brain Research Institute to the UCLA College," said UCLA Chancellor Albert Carnesale. "The new UCLA Institute for Stem Cell Biology and Medicine will enable us to continue fostering such interdisciplina...

"These results suggest the possibility that interferon lambda may be therapeutically useful in the treatment of chronic HBV or HCV infection." (M.D. Robek, B.S. Boyd, F.V. Chisari. 2005. Lambda interferon ...

Not-for-profit publishers call NIH public access rule a missed opportunity

Alaskan puzzles, monitoring provide insight about North Pacific salmon runs

...the Alaska Salmon Program are not subject to human activities such as dam building, logging or development. The money will help expand the scope of monitoring, fund new techniques for sampling and help make the UW database available through the Gordon and Betty Moore Foundation's Salmon Rivers Observatory Netw...

50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel

...ough ion channels are the basis for those cellular activities that give us thoughts, sights, tastes, sounds and our ability to move." "Consequently," he adds, "cells control these actions as carefully as we watch our finances, which is why so many of the most potent mediations we use to care for our patients' ...

WHO Warns Of Increased Risk Of Vector-borne Diseases In Tsunami-affected Areas

... strategy, WHO urgently requires US$67 million for activities through the next six months. Notes to editors The tsunami in Southeast Asia, has at least in some areas, led to environmental disturbance of the kind that would typically be associated with increased mosquito breeding. While pools of salt water wou...

Computational Method Speeds Mapping of Cell Signaling Networks

Information about the simultaneous activities of several signaling molecules in thousands of individual cells was analyzed using a powerful computational method called Bayesian network modeling. Bayesian analysis uses statistics to determine associations and dependencies between molecules in a n...
