POPSPrioNet Canada: prion network join in PrioNet Canada is a Network of Centres of Excellence for research on Bovine Spongiform Encephalopathy, commonly known as mad cow disease, and other Transmissible Spongiform Encephalopathies or prion diseases. The PrioNet Canada web site was built to serve as a portal for members and non-members alike, to access the latest findings in prion science and to discover the wealth of possibilities provided by the network concept. Prion Video Watch a short video on prions produced by the Alberta Prion Research Institute. PrioNews Read the Jan-March 2007 issue of PrioNet's newsletter.

POPSNews-Medical.Net 'Understanding how rogue prions kill cells is crucial to learning more about the prion diseases that remain a major concern for public and animal health following the BSE epidemic in UK cattle and the emergence of its human counterpart variant CJD. This work forms part of a major research strategy at the MRC Prion Unit to translate basic research findings into potential treatments in the years ahead. The underlying mechanism by which rogue prion proteins disrupt the UPS may be of wider relevance in understanding how misshaped proteins cause other disorders too, like Alzheimer's disease.''

POPSBeef eaters beware -- safety may be sent packing by Courtney Haden Creekstone sued the USDA in 2006, and in the case of David v. Goliath, the little guy unaccountably won. A decision handed down by a U.S. district judge in March decreed that Creekstone must be permitted to start its own testing June 1. However, thanks to its Hail Mersey call last week, the USDA can appeal the ruling and prevent Creekstone from testing indefinitely.

POPSBSE CASE CONFIRMED IN BC More recently (April 2007) was found that; Alzheimer's disease, Parkinson's disease, type II diabetes, the human version of mad cow disease and other degenerative diseases are more closely related at the molecular level. An international team of chemists and molecular biologists reported; „A mystery on which the new Nature paper sheds light is what causes different strains of prions (infectious proteins) in which the protein sequence is identical. Our research gives a strong hypothesis that the origin of prion strains is encoded in the packing of the molecules in the fibrils which we are seeing in the crystals…“

POPSColony Collapse Disorder Universal Prion 19 Aug 99 webmaster Could a bee sting cause scrapie? Yes, indeed -- there was an apparent near miss 23.6 million years ago in a common ancestor of sheep and cow -- a retrotransposon event that might have boosted prion protein production to levels fostering sporadic TSE. Ruminants contain a 1220 bp mariner retrotransposon in their 3' UTR portion of their mRNA. This element, with its terminal inverted repeats, are described by Lee as a fossil transposase pseudogene with homology to the Mellifera (bee) subfamily. It is probably an old insertion shared by all ruminants since it has 7-8 frameshifts and 5 stop condons -- figure 3 of the Lee paper shows a guided translation and the correct flanking human gene alignment. The insertion in cow/sheep occured between 27587 and 27588 in terms of human 3' UTR numbering, just downstream of the Bov-tA3, greatly increasing the length of ruminant mRNA.
