Gut Microbe Strikes Again: Ulcer-Causing Bug May Also Prevent Cancer
Lundi 06 Octobre 2008 - 10:00 - 3 mois depuis - 5 lectures - Presse spécialisée - Scientific American
The common ulcer-causing bug linked this summer to reduced rates of childhood asthma and allergies may also help protect adults against one type of cancer, according to a new analysis. Researchers report today in the journal Cancer Prevention Research that they found the stomach microbe Helicobacter pylori (H. pylori) may help prevent a major form of cancer of the esophagus (the muscular tube that carries food and drink from the throat to the stomach).

Montagnier, Barre-Sinoussi and zur Hausen Share Nobel
Lundi 06 Octobre 2008 - 07:25 - 3 mois depuis - 5 lectures - Presse spécialisée - Scientific American
A pair of French scientists who isolated the AIDS-causing human immunodeficiency virus (HIV) and a German scientist who determined that human papillomavirus (HPV) causes cervical cancer were awarded the Nobel Prize in Physiology or Medicine today. The Nobel committee's decision to give the prize to Luc Montagnier and Francoise Barre-Sinoussi, who isolated HIV in 1983, caps a long, bitter dispute between the Pasteur Institute in Paris, where they made their discovery, and American scientist Robert Gallo, who linked HIV to AIDS separately but was snubbed by the Nobel committee.

Could Our Own Proteins Be Used to Help Us Fight Cancer?
Mercredi 02 Juillet 2008 - 06:33 - 6 mois, 1 semaine depuis - 5 lectures - Cancer - 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.

Molecular Machines That Control Genes
Vendredi 03 Octobre 2008 - 12:25 - 3 mois depuis - 5 lectures - Presse spécialisée - Scientific American
Editor's Note: This article was originally published in the February 1995 issue of Scientific American. We are reposting it this week because Robert Tijan has just been named president of the Howard Hughes Medical Institute.Asthma, cancer, heart disease, immune disorders and viral infections are seemingly disparate conditions. Yet they turn out to share a surprising feature. All arise to a great extent from overproduction or underproduction of one or more proteins, the molecules that carry out most reactions in the body. This realization has recently lent new urgency to research aimed at understanding, and ultimately manipulating, the fascinating biochemical machinery that regulates an essential step in protein synthesis: the transcription of genes. For a protein to be generated, the gene that specifies its composition must be transcribed, or copied, from DNA into strands of messenger RNA, which later serve as the templates from which the protein is manufactured.
