New clue to how telomeres work
Jef Akst | Mar 24, 2010 | 3 min read
One protein appears to play an integral role in protecting telomeres, and possibly preventing cancerous growth, according to a study published this week in Science. Chromosomes with fluorescently tagged telomeres in cells that lack Rap1and Ku. The arrows point to examples of telomere-sister chromatid exchanges.Image: Titia de Lange laboratoryThe protein in question is part of a complex called shelterin, which prevents a potentially dangerous type of DNA repair that can shorten telomeres and

Sometimes it seems as if genome projects are cropping up everywhere.1 But until costs come down, limited resources are being largely concentrated into what Joseph Nadeau, professor of genetics at Case Western Reserve University School of Medicine, calls "the genome seven," an apples-and-oranges list of viruses, bacteria, fungi, Arabidopsis thaliana, Drosophila melanogaster, Caenorhabditis elegans, and mouse, with Homo sapiens in its own category.2 Researchers widely acknowledge that in the rod

Putting Polio to Good Use Add polio to a host of other viral and bacterial foes that, in modified forms, could prove therapeutically beneficial. Although Russian scientists attempted to use polio to treat cancer in the 1960s--unpublished experiments about which little is known--a recent brain cancer study in mice is the first modern-day attempt to harness the power of the virus (M. Gromeier et al., "Intergeneric poliovirus recombinants for the treatment of malignant glioma," Proceedings of the
