Source of molecular triggers in cutaneous T cell lymphoma identified

...to CTCL receptors, stimulating the malignant cells rapidly divide. "This finding has broad implications for the understanding, diagnosis, and treatment of CTCL, as well as potentially contributing to the investigation of other types of lymphomas," said Edelson. "It may now be possible to identify specific a...

Mouse brain cells rapidly recover after Alzheimer's plaques are cleared

...wellings previously observedon nerve cell branches rapidly disappeared. "Theseswellings represent structural damage that seemed to be wellestablished and stable, but clearing out the plaques often led to rapidrecovery of normal structure over a few days," says senior author DavidH. Holtzman, M.D., the Charl...

Inexpensive, mass-produced genes core of synthetic biology advances at UH

...neurological diseases, we’ve often wished we could rapidly synthesizemany variations of large naturally occurring genes. The costs ofcurrent technology have prevented us from doing this, but Dr. Gao’sresearch will break down that barrier.?This technology offers tremendous potential benefits, as syntheticgene...

Genome-wide mouse study yields link to human leukemia

... first goes through a pre-leukemic stage marked by rapidly expanding T cells and natural killer cells, both major components of the immune system. In comparing the mice in the pre-leukemic stage and those with ALL with normal mice, researchers found that methylation, a chemical process that adds methyl mole...

Sea skate experiment sheds light on human cell transport

...ch water, diluting blood and other body fluids and rapidly causing death. So how do skates do it? Goldstein and Musch learned how cellular channels, or gates, spring into action when skate red blood cells become engorged with water. Vesicles, or tiny fluid-filled sacs, carry these gates up to the cell membr...

Color-blind method opens new doors in DNA sequencing

...the ability to sequence an individual's own genome rapidly and inexpensively. Metzker and the major developers of this technology filed a patent on PME in 2001, which has been exclusively licensed to LaserGen for commercial development. Others who participated in the research include Carter Kittrell, Bruce...

Gene variations explain drug dose required to control seizures

...her physicians can safely increase drug doses more rapidly for some patients. Such a trial might also allow physicians to identify patients who might safely take a smaller dose, thereby minimizing their risk for adverse side effects, he added. The findings in epilepsy set the stage for scientists to evaluat...

Scientists collaborate to assess health of global environment

...ch as food, clean air, potable water and fuel--are rapidly being degraded. "[The assessment] examines the state of the global environment, but it's more than that," said Harold A. Mooney, the Paul S. Achilles Professor of Environmental Biology at Stanford University and co-chair of the assessment's science ...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...ffymetrix, which makes so-called "gene chips" that rapidly scan millions of small sections of chromosomes to detect gene activity. But the scanning results left them with a huge amount of data, and the daunting task of deciphering what it means in terms of how genes function. For that part of the project, th...

Genetically modified natural killer immune cells attack, kill leukemia cells

...were the development of a laboratory technique for rapidly producing a large, pure population of NK cells from a small sample of blood; and developing a technique for genetically modifying NK cells so that they would become potent killers when they encountered leukemic cells. In order to grow large populati...

Highly adaptable genome in gut bacterium key to intestinal health

Their findings are reported in the Mar...

Researchers trace evolution to relatively simple genetic changes

...fferent locations." Because this trait evolves so rapidly after ocean fish colonize new environments, he added, "we wondered whether the genetic variant (the mutant gene) that controls this trait might still exist in the ocean fish. So we collected large numbers of ocean fish with complete armor, and we fou...

DNA Recombination and Repair—A New Twist to RecA Function

...eriments have shown that filament assembly spreads rapidly in the 5'-to-3' direction once the first RecA molecule is loaded onto DNA. At the same time, ATP hydrolysis causes the release of RecA from DNA, but the exact rate of RecA dissociation is not known. Experiments suggest, however, that RecA molecules o...
