Genome-wide mouse study yields link to human leukemia

...but only in the mice with full-blown ALL. Further tests revealed that the methylation pattern in the mice with leukemia is strikingly similar to the pattern of methylation in human leukemia. In the process, the researchers also identified a new gene that when methylated, appears to interrupt normal cell ...

A similar approach might also prove useful for other conditions, such as Parkinson's disease and cancer, in which patients' drug dosage...

Poplar trees redirect resources in response to simulated attack

...es there," Ferrieri said. "We will have to do more tests to see what compounds are formed." Ferrieri believes there may be an increase in compounds that resist microbial attack after plants have soaked up atmospheric carbon dioxide, therefore countering the effects of fossil-fuel combustion. This is a str...

Scientists develop new color-coded test for protein folding

..., which works on the same principle as ordinary pH tests that measure the acidity of water, is described in the March 2005 issue of the journal Chemistry and Biology. "What we've developed is a simple and inexpensive sensor for determining when a protein changes its conformation," said study co-author Ric...
