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

...wasn't enough to turn these overactive lymphocytes into lymphoma cells. "The coup de grace consisted of a complete elimination of the apoptotic response through loss of p53 function," Grosveld said. "In fact, all TEL2/MYC B-cell lymphomas had lost their p53 function." Grosveld's team found that this seq...

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

...most functionally important proteins are assembled into machinery from one species to another is also, to a certain degree, 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...

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

.... The flight simulator, which fools a tethered fly into thinking it is flying freely through the air, is necessary to produce a stable pattern of wing motion and enabled the team to capture X-ray images at different stages of muscle contraction. By combining the technologies, the researchers could reconst...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

...evelopmental events. They injected individual CNEs into embryos, along with a green fluorescent protein (GFP) reporter. By day two of development, 23 out of 25 CNEs injected had upregulated GFP expression, indicating interaction of these sequences with endogenous transcription factors. Different CNEs caus...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...to people. The spectrometry measurements were fed into a computer database to create a computational model of the P. gingivalis proteome, resulting in a surprising find. “Some of the proteins we previously thought were important when they were expressed in the lab proved not to be when the organism is i...

Scientists solve structure of key protein in innate immune response

...stal structure of CD14, providing crucial insights into how the receptor binds to its ligands. "Our structure shows that CD14 has a large hydrophobic pocket near its amino terminus," says Dr. Lee. "We propose that this pocket is the main binding site for LPS because previous biochemical studies demonstrat...

New Treatment Rivals Chemotherapy For Lymphoma, Study Finds

...erapeutic regimen, a radioactive antibody injected into the bloodstream that targets and kills cancer cells. Of the 76 patients enrolled in the study, 95 percent responded to the treatment and 75 percent had a complete response, meaning no evidence of cancer remained. More than three-quarters of patients ...

World's largest rainforest drying experiment completes first phase

... "This experiment provides researchers with a peek into the future of this majestic forest, a future that will most likely be drier because of global warming, El Niño episodes, and even the drying effects of rainforest clearing and burning itself." First, the biggest surprise noted thus far has been the ...
