Wisconsin scientists grow critical nerve cells

...k by an idea: Why not apply a chemical known to be necessary for a later stage of neuron development to a much earlier step in the process? The hunch paid off and turned out to be the final piece of the puzzle. The discovery, says Zhang, demonstrates that human stem cells do not necessarily differentiate in ...

Genes In The Interferon System Important In Systemic Lupus Erythematosus

Novel technology detects human DNA mutations

...terest. Once that base pair is located, it is then necessary to determine if either of the bases is mutated (i.e., has SNPs). Nanosphere's technology can rapidly, easily, and accurately interrogate both bases in the pair to determine if they are homozygous (i.e., both are mutant or normal) or heterozygous (i.e...

Plants, animals share molecular growth mechanisms

... protein strings, called actin filaments, that are necessary for cellular growth, said Dan Szymanski, agronomy associate professor and lead author of the study. Knowledge of the biochemical reactions involved in this process eventually may allow researchers to design plants better able to protect themselves fr...

Transplantation Of Monkey Embryonic Stem Cells Reverses Parkinson Disease In Primates

Gene therapy converts dead bone graft to new, living tissue

... as a kind of "calcium bank." 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 the...

Gene variations explain drug dose required to control seizures

Patients often undergo a lengthy process of trial and error to find the dose ...

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

...archers found that sustained expression of Gli2 is necessary forthe continued growth of these tumors. When Dlugosz and colleaguesturned Gli2 off, the BCC tumor cells stopped growing and wereeliminated by a programmed cell death process. These results areconsistent with previous work from other labs studying di...

Highly adaptable genome in gut bacterium key to intestinal health

"Untilrecently, we thought it was necessary to use visible light to produceoxygen through photosynthesis, but now we know there are at least threeorganisms that can do this using infrared radiation as well."All three of these organisms are closely related species ofAcaryochloris, but the other...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

"The presence of growth hormone and IGF-1 is necessary for maintenance of cognitive function and prevention of cartilage degeneration," Sonntag and his colleagues reported in an article in Endocrinology, published on-line today. But the hormones also increase cancer and other diseases that limit lifespan...

Bird Brains Show How Trial and Error May Contribute to Learning

"It means this part of the brain is important for instructing or allowing changes in the song," said Mimi Kao, first author of a paper in the February 10,...

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

...iscovery. "Maybe the target protein has a good and necessary role in 10 interactions, but the 11th is the only one we would need to eliminate," said Ideker. "What we really want are drugs that interfere with just that one disease-causing interaction." Systems biologists such as Ideker say their ultimate goal ...

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