It is estimated that up to 90% of patients with AS could be HLA-B27-positive in most ethnic populations throughout the world; however, only 2% of HLA-B27-positive individuals in the general populations could be affected by AS, which might point to the role of other gen ...

Analyses of the E3 ubiquitin-ligase target adapter

... Ubiquitylation, the attachment of ubiquitin to proteins to mark for degradation by proteasomes, is crucial for proper organism function. One family of complexes that play a role in this process is the BTB/Cullin 3/RBX E3 ubiquitinprotein ligases. Three proteins; a BTB (Bric-a-Brac, Tramtrack, Broad ...

History of genetic engineering

Genetic modification caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973. Advances have allowed scientists to manipulate and add genes to a variety of different organism and induce a range of different effects. Since 1976 the technology has been commercialised, with companies producing and selling genetically modified food and medicine.
