Could Our Own Proteins Be Used to Help Us Fight Cancer? [Scientific American Magazine]
Mercredi 02 Juillet 2008 - 06:33 - 6 mois, 1 semaine depuis - Presse spécialisée - Scientific American
In 1962 someone at the Genetics Institute in Pavia, Italy, turned up the temperature in an incubator holding fruit flies. When Ferruccio Ritossa, then a young geneticist, examined the cells of these “heat shocked” flies, he noticed that their chromosomes had puffed up at discrete locations. The puffy appearance was a known sign that genes were being activated in those regions to give rise to their encoded proteins, so those sites of activity became known as the heat shock loci.The effect was reproducible but initially considered to be unique to the fruit fly. It took another 15 years before the proteins generated when these chromosome puffs appear were detected in mammals and other forms of life. In what is certainly among the most absorbing stories in contemporary biology, heat shock proteins (HSPs) have since been recognized as occupying a central role in all life--not just at the level of cells but of organisms and whole populations.

Looking at Yesterday's Genes for Tomorrow's Cures [Scientific American Magazine]
Mercredi 02 Juillet 2008 - 06:31 - 6 mois, 1 semaine depuis - Presse spécialisée - Scientific American
If humans could reanimate one of our ancient ancestors, we could quickly learn much more about how people once went about their lives than any study of dusty bones and artifacts would reveal. Our forebear might even teach us a few old tricks that could be used to help the living.That is in essence what researchers in Germany and Hungary were after when they re-created Harbinger3_DR, a long-extinct precursor of at least two modern human genes: they wanted to watch it operate inside living cells. Not just any DNA relic, Harbinger3_DR is an ancient transposon--a so-called jumping gene, able to cut itself out of an organism’s genome and reinsert itself in a different location. Modern scientists would love to master its secrets so they could more precisely control where genes introduced for gene therapy incorporate themselves into a patient’s DNA strand. [More]
