Q&A: Translation deCODEd

By | March 26, 2010

As far as buzz words go in the life science community, "translational research" has had a pretty long lifespan. Transforming laboratory-hatched ideas into lucrative commercial products has, is, and will be a holy grail sought by scientists and business types alike. But successes in the field of translational research are few and far between. One of the most notable burnouts befell Icelandic genetics company deCODE, which assembled an impressive genomic database, and identified several key diseas

New clue to how telomeres work

By | March 25, 2010

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
