Lab mice rescued from Type 1 diabetes via dendritic cell-assisted therapy
...0,000) of regulatory T cells where they are needed arrests
the onset of Type 1 diabetes in the animals. This research used a special source of T cells from mice genetically altered to have a majority of cells directed to the islets. Now Tarbell will extend the strategy into mice with a normal repertoire to s...
Study sheds light on critical relay in visual circuit of the brain
...s do not form. "Basically, taking out the subplate arrests
cortical development," says Patrick Kanold, a research fellow in neurobiology at HMS and lead author of the study. Kanold showed that neurons in the visual cortex with a disrupted subplate could not distinguish light bars of different orientations--w...
New findings suggest colorectal cancer origins are different than previously thought
...ntly, artificial interruption of protein synthesis arrests
cellular proliferation. Besides other proteins, the increased protein synthetic rate in proliferating cells occurs in proteins that control the growth process. In malignant cells, these proteins are coded by protooncogenes. The authors of "Effect of...
Researchers identify gene for most common paediatric malignant brain tumour
...tion to medulloblastoma cells to determine if this arrests
tumour growth. We will also look at small molecule compounds that are known to work in the Hedgehog signaling pathway that could potentially be used as a therapy for medulloblastoma," added Dr. Rutka, holder of the Dan Family Chair in Neurosurgery an...
UCSF finding offers provocative insight into what drives cancer
...ll, oncogenes have some form of default valve that arrests
further cell growth and limits their potential to form tumors. A next step, says Evan, will be to determine whether other proteins that make cells proliferate and that get mutated in cancer, such as the cyclin dependent kinases and the E2F transcript...
Rockefeller researchers identify defense system in plants
...BAa plant hormone known to inhibit germinationalso arrests
growth of newly germinated Arabidopsis plants for up to 30 days. Moreover, they provide evidence that ABA activates a recently isolated Arabidopsis protein called ABI5 and demonstrate that this protein is essential to the newborn plants ability to pr...
Report on dietary supplements containing ephedra makes urgent call for research to develop dose guidelines, safety warnings
...s effects among these people included five cardiac arrests
- two fatal and three resulting in permanent brain damage and disability; four strokes and ten cases of hypertension. When a second group was included in the analysis - those whose physical symptoms were "possibly" related to ephedrine products - the...
Unique study reveals new details on how genes are transcribed

in these bulk studies were artificially induced by solution conditions. "Ours is the first study in which pause dynamics of RNAP have been studied systematically at a single molecule level and on enzymes that were actively transcribing," says Bustam...

Notre Dame Paleontologist Finds Damage Done To T. rex Skull

have been announced. "This is about as bad as I could have imagined," Rigby said today. "We had a virtually complete skull and now I'm wondering what I can do to repair the damage." Rigby and a crew of volunteers from the Earthwatch Institute discove...
Newly Discovered Gene Halts Cell Division and May Have Cancer Link
...ng Cancer Center have identified a human gene that arrests
cell division in the laboratory and, when defective, may lead to the development of cancer. They reported the finding in the Oct. 11 issue of the journal Science . The study suggests that if the gene's activity is blocked, cell division continues...
