Cancer: 'Primitive' gene discovered (2/15/2010)

Cancer: 'Primitive' gene discoveredTo find the causes for cancer, biochemists and developmental biologists at the University of Innsbruck, Austria, retraced the function of an important human cancer gene 600 million years back in time. For the first time, they have identified the oncogene myc in a fresh water polyp and they have shown that this oncogene has similar biochemical functions in ancestral metazoan and in humans. The scientists published their findings in PNAS. ...> Full Article

Gene switch sites found mainly on 'shores,' not just 'islands' of the human genome (1/21/2009)

Scientists who study how human chemistry can permanently turn off genes have typically focused on small islands of DNA believed to contain most of the chemical alterations involved in those switches. But after an epic tour of so-called DNA methylation sites across the human genome in normal and cancer cells, Johns Hopkins scientists have found that the vast majority of the sites aren't grouped in those islands at all, but on nearby regions that they've named "shores." ...> Full Article

It commands a signaling network more elaborate and diverse than found in any multicellular organism higher up on the evolutionary tree ...> Full Article


Evolution Of Human Genome's 'Guardian' Gives People Unique Protections From DNA Damage (1/21/2008)

Evolution Of Human Genome's 'Guardian' Gives People Unique Protections From DNA DamageHuman evolution has created enhancements in key genes connected to the p53 regulatory network -- the so-called guardian of the genome -- by creating additional safeguards in human genes to boost the network's ability to guard against DNA damage that could cause cancer or a variety of genetic diseases, an international team of scientists led by Cincinnati Children's Hospital Medical Center writes in the Jan. 22 Proceedings of the National Academy of Sciences. Because genetically engineered mouse models are increasingly powerful tools in understanding the risks and mechanisms of human diseases -- and rodents do not have the same evolution-based safeguards in p53 function as humans -- the study also underscores the need for additional considerations in the interpretation of research using rodent models. ...> Full Article

Unscrambling the Gibbon Genome (3/9/2007)

Unscrambling the Gibbon GenomeThe arboreal, branch-swinging antics of the gibbon are nothing compared to the acrobatics its genome has undergone during evolution. While the genomes of humans and other primates still resemble that of their common ancestor, the massive genomic scrambling of the gibbon genome has rendered it a complex puzzle. Solving that puzzle, scientists believe, could help reveal how evolution experiments with genomic rearrangement, as well as how chromosomes can become unstable in cancer and other genetic diseases. ...> Full Article
