:On second thought, we actually have a lot of active proviruses ( active for our species, I mean, not in adults ).
22.
PVCV can exist as an endogenous provirus within the " P . hybrida " genome and may be induced by environmental stress or wounding.
23.
Transcription from an integrated HIV-1 provirus generates a single 9 kilobase ( kb ) pre-mRNA containing multiple splice sites and nuclear retention signals.
24.
Mechanisms such as DNA methylation and histone modification seem to play important roles in the suppression provirus transcription, such that proviral activity can be finally silenced.
25.
Endogenous viral elements ( EVEs ) are proviruses ), can persist in the germline, being passed on from one generation to the next as host alleles.
26.
The researchers described these provirus reservoirs as the " Trojan horse " of AIDS, and said they may lurk in the brain and retina cells, too.
27.
Human endogenous retroviruses ( HERV ) proviruses comprise a significant part of the human genome, with approximately 98, 000 ERV elements and fragments making up 5-8 %.
28.
A latent infection may become productive in response to changes in the host's environmental conditions or health; the provirus may be activated and begin transcription of its viral genome.
29.
In test-tube experiments, the scientists were able to grow the AIDS virus when they combined tiny provirus samples from the men with blood from individuals who had never been infected.
