Scientists Resuscitate A 5 Million-Year-Old Retrovirus inside our DNA!
A team of scientists has reconstructed the DNA sequence of a 5-million-year-old retrovirus and shown that it is able to produce infectious particles. The retrovirus--named Phoenix--is the ancestor of a large family of mobile DNA elements, some of which may play a role in cancer.The study, which is the first to generate an infectious retrovirus from a mobile element in the human genome, is considered a breakthrough for the field of retrovirus research. The findings are reported in Genome Research. "Phoenix became frozen in time after it integrated into the human genome about 5 million years ago," explains Dr. Thierry Heidmann, lead investigator on the project. "In our study, we've recovered this ancestral state and shown that it has the potential for infectivity." Posted by: 3dc 2006-11-07 |
