Philadelphia Researchers Found A Novel Way To Fight Several Kind of Cancers
... both surprised and lucky," he says. "Velcade is a proteasome
inhibitor, but it also induces the lytic cycle thereby activating the TK in the Epstein-Barr virus. Once the TK is activated, we can image the tumors." To test their findings, the researchers used mice carrying human Burkitt's lymphoma, a cancer o...

'Mix and match' of proteins may have a significant role in immunity
...ieces, leads to the formation of peptides. "The proteasome
can splice peptides together," says Warren. “Every once in a while, new peptide bonds will be created, not just destroyed. It isn't clear why this happens, or what the newly spliced peptides do. But as the molecules end up on the cell's surface, they...
Cellular System Causing Destruction Of Faulty Proteins In Cystic Fibrosis Identified
...asome. This trash system is known as the ubiquitin proteasome
pathway. "We've identified the trash collectors that recognize misfolded proteins, decide if they might be toxic to the cell and mark them with ubiquitin. The ubiquitinated proteins, including faulty CFTR, are then degraded or shredded by the prot...
