Association of herpesvirus with lung disorder questioned

...n at a Tokyo hospital from 1981 to 2003. They also examined samples of lung tissue from 12 patients with other forms of pulmonary hypertension. All 22 were Japanese. For a control group, the scientists studied Kaposi's sarcoma tissue samples obtained from unrelated patients. Like the authors of the earlier s...

Quantum Dots Research Leads to New Knowledge about Protein Binding in Plants

... the molecules togerminated lily pollen grains and examined them under a confocalmicroscope.This is the very first time that Quantum Dots have been utilized forlive imaging in plant systems.

Neuronal 'traffic jam' marks early Alzheimer's disease

...lular proteins. Goldstein and his colleagues also examined brain sections taken at autopsy from humans with different stages of Alzheimer's disease. They detected the same kinds of swelling in those samples that they had seen in the mice. "This was a small, initial neuropathological study, but we believe tha...

Timing is everything: First step in protein building revealed

Combination therapy boosts effectiveness of telomere-directed cancer cell death

...ndation for Cancer Researchin Tokyo and colleagues examined what happens to cancer cells whentelomerase inhibition is combined with inhibition of an enzyme calledtankyrase 1 that is involved in making telomeres accessible totelomerase. The researchers found that both tankyrase 1 activity andtelomere shortenin...

Genome-wide mouse study yields link to human leukemia

...ature.com/ng/. "This is the first time anyone has examined methylation in leukemia on a genome-wide basis in a mouse, and the findings offer important implications for patient care, since we know that methylation, which alters gene function, can be reversed," says Christoph Plass, senior co-author and a memb...

NYU Study Reveals How Brain's Immune System Fights Viral Encephalitis

...y can fight viral encephalitis. Specifically, they examined how type I interferons--proteins made by the body that are released in response to stimuli, notably infection--work in neurons and to determine if nerve cells' response to interferons is similar to that of other cells. Examining the effect of the vi...

Scientists document complex genomic events leading to the birth of new genes

...gent from those of RanBP2, Bork and his co-workers examined the subcellular localization of one of the RGP-family isoforms. In contrast to RanBP2, which is found exclusively at the nuclear envelope, this RGP-family protein was detected in discrete cytoplasmic locations, thereby confirming its functional diver...
