Vital step in cellular migration described by UCSD medical researchers

...medicine. "Since cell migration plays an important role in the immune response, as leukocytes move toward targets, a therapy that stops that movement could potentially help in autoimmune disorders where the body's immune system incorrectly attacks the body's own tissue." From the genesis of human life to...

Critical role in programmed cell death identified

... the February 17 issue of Nature, demonstrates the role of mitochondria, the cellular power plant, in prompting worm cells to self destruct. These results unify cell death models along the evolutionary spectrum, from simple animal systems to humans. In spite of its name, programmed cell death, or apoptos...

ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors

.... In addition, these pigments may play a valuable role in maintaining the health of parrots. McGraw cites an independent study on the parrot pigments that suggests that they can act as anti-oxidants to quench free radicals and potentially protect cells and tissues in the body from oxidative damage. Now,...

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

...mans. "Gene duplication is known to play a leading role in evolution for the creation of new genes," explained Francesca Ciccarelli, Ph.D., lead author on the study. The key to this, however, is that the duplicated copies of genes very quickly evolve functions that are significantly different than those o...

DNA Recombination and Repair—A New Twist to RecA Function
