DNA sequence controls expression of gene involved in cancer
...mally, bcl-2 produces a protein that inhibits cell death
or apoptosis. This protein keeps death-promoting factors from producing holes in the mitochondria which can result in calcium and destructive proteins leaking out into the cell. However, the overexpression of bcl-2 in damaged cells can lead to the co...
An embryonic stem cell model for Parkinson's disease
...stress has long been associated with neuronal cell death
and neurodegenerative diseases like Parkinson's. Proving a causal relationship between oxidative stress and neurodegeneration, however, requires establishing a molecular mechanism. These results support a link between oxidative damage and disease, an...

usually occurred within six days of inoculation. Similar results were seen in monkeys that received the same dose of either virus by the intravenous route alone. Having demonstrated that it was possible to achieve lethal infection of primates using ...
Use of aspirin or other NSAIDs increases survival
... COX-2 enzymes, NSAIDs may enhance programmed cell death
(apoptosis) and inhibit the development of blood vessels (angiogenesis) that feed a tumor. The Fox Chase researchers concluded that inhibiting these COX enzymes holds promise in prostate cancer treatment and warrants further studies. In addition to ...

New study on smallpox in monkeys reveals tactics of a killer
...e findings shed light on how the virus caused mass death
and suffering, and will help point the way to new diagnostics, vaccines and drugs that would be needed in the event of a smallpox bioterror incident. The study, led by David Relman, M.D., of Stanford University, is now online in the Proceedings of th...
Gladstone researchers resolve key Huntington's disease mystery in Nature cover story

and might be pathogenic, or predicted longer survival and might be beneficial. The findings suggest, says Finkbeiner, that inclusion bodies lock up mutant huntingtin in other parts of a cell and keep it from interfering with the rest of the neuron in...
Study using robotic microscope shows how mutant Huntington's protein affects neurons
