How One Virus Uses Mimicry To Replicate Successfully: Related Mechanis
Both viruses and cancers subvert the growth-control machinery in a cell to serve their own needs. According to a new study, at least one virus uses mimicry to gain access to that machinery. A common target for both is a cell protein called the retinoblastoma protein, or pRb, which serves to block cell division when potentially cancer-causing gene mutations are present. The Ruminant: A Daily Update on the Debates Shaping the 2007 Farm Bill

A research team analyzed the differences and relevance of Yes-associated protein and survivin, and explored the correlation and significance of their expression in gastric carcinoma and precancerous lesions. It was found that YAP might play an important role as a carcinogenic factor and might induce survivin expression. Detecting both markers together might help in early diagnosis of gastric carcinoma.
