Measuring Enzymes At End Of Cancer Pathway Predicts Outcome Of Tarceva, Taxol

...ll division, Ueno and his colleagues have recently reported that increased activity of CDK1 correlated with a cell's sensitivity to Taxol. The CDK enzyme plays a role in cell division, and researchers believe that it functions in part as a monitor of cell cycle activity. Ueno theorizes that if something goes...

Activation of thermoreceptors mediates raw garlic's burning pungency

The findings are reported in the May 24 issue of Current Biology by a team led by Ardem Patapoutian of The Scripps Research Institute and the Genomics Institute of the Novartis Research Foundation. Despite garlic's popularity, the compounds responsible for its pungency, as w...

Study reveals candidate targets for anti-retroviral therapeutics

...plication of a model retrovirus. Their results are reported in the May issue of Genome Research. Many organisms harbor mobile genetic elements that are non-pathogenic molecular relatives of retroviruses. In budding yeast, these mobile elements (called Ty ?or transposable yeast ?elements) encode proteins that...

Signs of aging: Scientists evaluate genes associated with longevity

... as their wild-type counterparts. Daf-2 was first reported as a critical aging-associated gene in 1993, but since that time, scientists have identified dozens of additional genes that are crucial for longevity. "Aging is a complex process," explains Dr. Brooks-Wilson. "It is commonly believed that a variety ...

The most recently reported of these simulations is in an article by Julie Schames, Richard Henchman, Jay Siegel, Christoph Sotriffer, Haihong Ni, and McCammon in the Journal of Medicinal Chemistry of April 8, 2004. These simulations revealed that a "trench" opens intermittentl...

Basis for DNA ejection from single phage particles

In the new work reported this week, researchers have evaluated whether the energy thus stored is sufficient to permit phage DNA ejection, or only to initiate that process. The researchers used fluorescently labeled phage DNA to investigate in real time (and with a resolutio...
