Timing is everything: First step in protein building revealed

...trophy remains a mystery, the newdiscovery reveals exactly how eIF1 regulates the ribosome's activity.The research team has demonstrated that eIF1's mere presence on theyeast ribosome prevents the machinery from getting started. Only afterits release from the complex can the ribosome start making proteins."N...

Genome-wide mouse study yields link to human leukemia

...tingly, that same range of methylated fragments is exactly what we find in human leukemia, too," says Caligiuri, "so that gives added merit to our mouse model as an investigative tool." Using data from the methylation studies, Caligiuri and Plass were able to identify a particular stretch of DNA, called Id4...

Found: Missing sequence of the human Y chromosome

...eexhibited between 95-99% homology to sequences on exactly half (11 of22) of the other chromosomes in the human genome, including thepericentromeric regions of autosomes (non-sex chromosomes) 1, 2, 3, 4,9, 10, 11, 14, 15, 16, and 22. This remarkable similarity can beattributed to segmental duplications, a ph...

Critical role in programmed cell death identified

...and harder to pinpoint. In worms, scientists know exactly which cells are dying, and when and where. During development, 1,090 cells form, but 131 of these cells die; the same cells always die at the same time and at the same place. This feature makes it possible to identify mutant worms, in which cells tha...

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

Studies reveal methods viruses use to sidestep immune system

...r. Gale said. "We're currently working to identify exactly what proteins the viral protease is attacking, which could help toward further developing the protease inhibitors and more effective therapies for hepatitis C and possibly other viral infections." A third paper, also appearing in PNAS, describes col...

Alcohol's effects on gene expression in the central nervous system

... regions of animal models. "All of our cells have exactly the same deoxyribonucleic acid (DNA), which means they all have the same genes," explained William J. McBride, symposium organizer and professor of neurobiology at the Indiana University School of Medicine. "The reason that different cells can appear...

MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks

...novative genomic research projects."Moleculizer is exactly the sort of development that one wants to seefrom multidisciplinary work," explained Dr. Brent. "The mathematicaland algorithmic skills that Dr. Lok brought to the problem could onlycome from one with his strengths, but the work is important because ...

NC State scientist finds soft tissue in T. rex bones

...Schweitzer hopes that further research will reveal exactly what the soft structures isolated from these bones are made of. Do they consist of the original cells, and if so, do the cells still contain genetic information? Her early studies of the material suggest that at least some fragments of the dinosaurs'...

Plants defy Mendel's inheritance laws, may prompt textbook changes

...is process works," Pruitt said. "Then we will know exactly what role this gene plays." Pruitt's team already knows that animals don't have hothead genes, either normal or mutated, so the scientists must investigate which genes might affect this novel inheritance in both plants and animals. "There are proba...

NJIT Presidential Award winner takes stem cell research another step

... turn into different cell types. Arinzeh is doing exactly that: developing signals, in the form of biomaterials, that will help adult stem cells turn into cells that, if injected into a diseased area of the human body, could regenerate damaged tissue. Her research has also led to two major stem-cell discov...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

...art multiplying entirely out of control. "This is exactly what we saw in mice that were genetically modified so their B lymphocytes were over-expressing MYC," Grosveld said. "When we forced over-expression of TEL2 in these mice, we curtailed apoptosis in the precancerous B lymphocytes that were being forced...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...ee, conserved," said Ideker. "The circuitry is not exactly the same. In fact, there are striking differences that warrant more investigation." The team included Roded Sharan, a computer scientist currently at the Tel-Aviv University in Israel; Tanja Kuhn and Peter Uetz, researchers at the Institute of Genet...

X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

Sequencing of marine bacterium will help study of cell communication

...elected by Drs. Ruby and Greenberg to be sequenced exactly because it is so well studied," said Stevens. "This was also the first time a non-pathogenic Vibrio species has been sequenced and there is the potential for valuable lessons as it is compared with the pathogenic species. I was particularly pleased w...

Vampire bats keep out of trouble by running

...swipe at the nocturnal visitor. It remains unclear exactly what the native prey were before the introduction of cattle, he adds. The Cornell zoologists plan to go a step further and compare the vampire bat to another species of bat endemic to New Zealand. Riskin explains, "The vampire bat is good on the gro...

Molecular models advance the fight against malaria

...ply computerized modeling techniques to illustrate exactly how the drug interacted with the cytochrome bc1 complex ?the respiratory enzyme the parasites need to live and multiply -- on a molecular level. With this new understanding of how the parasites were able to counter the effects of atovaquone, research...

Low level of extinction during ice age linked to adaptability

...be relatively immune. Though it's difficult to say exactly what the implications are for the world we live in, what I can say is that it is worrisome." Powell looked at extinctions during an age when glaciers reached to within 35 degrees of the equator, roughly as far south as a line between present-day Ral...

Buying Time Through Hibernation on Demand

...m warm-blooded to cold-blooded creatures, which is exactly the same thing that happens naturally when mammals hibernate," said lead investigator Mark Roth, Ph.D., whose findings will be published in the April 22 issue of Science. "We think this may be a latent ability that all mammals have -- potentially ev...
