Traduction de «gène de la protéine-prion » (Français → Anglais) :

The impossibility of distinguishing these proteins and bone spicules, which do not pose a TSE risk from proteins of ruminant origin which could contain BSE-carrying prions, resulted in a number of high-profile, extremely costly, wasteful and unnecessary withdrawals from shipments and, more controversially, beet-based animal feed, owing to this harmless and unavoidable adventitious presence of non-ruminant proteins.

The difference lies in the make-up of the gene responsible for the prion protein (the rogue form of which is responsible for causing scrapie).

The transfer of information from DNA (or a gene) to a protein is a complicated process involving several stages. Firstly, the genes are transcribed in the polynucleotides known as ribonucleic acid (RNA).

These tests can only detect the affected prion protein above a certain level.

36. Considers, bearing in mind that the number of genes seems far lower than previously thought, that much less importance should be attributed to the idea that genes are the sole or overriding contributory factor in given outcomes, which appear instead to result from complex interaction processes involving genes, proteins, and environment; once the emphasis on predictivity has been removed, the possibility of using genetic data to assess people’s prospects should not be permitted, since the decisive relationship with proteins and environment is disregarded, producing distorted or incomplete images of the person in question; takes the ...[+++]view that an individual does, however, have the right to have genetic tests carried out;

We have been eating scrapie-infected sheep for over two hundred years, with no ill effect, and that is because the structure of the shape of the prion, the non-infectious protein, in the sheep, is not compatible to that in the human brain, unlike the rendered cattle or beef prion, that replaces the protein necessary in our brains.
