Marine origin of retroviruses in the early Palaeozoic Era

open access: yesNature Communications, 2017
Endogenous retroviruses are viruses that have become integrated into the genomes of their hosts. Here, the authors investigate the evolution of foamy-like endogenous retroviruses, and, by taking into account the temporal dynamics of the rate of viral ...

Endogenous viral sequences from the Cape golden mole (Chrysochloris asiatica) reveal the presence of foamy viruses in all major placental mammal clades. [PDF]

open access: yesPLoS ONE, 2014
Endogenous retroviruses provide important insights into the deep history of this viral lineage. Endogenous foamy viruses are thought to be very rare and only a few cases have been identified to date.

Defending the genome from the enemy within:mechanisms of retrotransposon suppression in the mouse germline [PDF]

open access: yes, 2013
The viability of any species requires that the genome is kept stable as it is transmitted from generation to generation by the germ cells. One of the challenges to transgenerational genome stability is the potential mutagenic activity of transposable ...

Porcine Endogenous Retroviruses and Xenotransplantation, 2021

open access: yesViruses, 2021
Porcine endogenous retroviruses (PERVs) are integrated in the genome of all pigs, and some of them are able to infect human cells. Therefore, PERVs pose a risk for xenotransplantation, the transplantation of pig cells, tissues, or organ to humans in ...

Domestic chickens activate a piRNA defense against avian leukosis virus [PDF]

open access: yes, 2017
PIWI-interacting RNAs (piRNAs) protect the germ line by targeting transposable elements (TEs) through the base-pair complementarity. We do not know how piRNAs co-evolve with TEs in chickens.

Sensitive detection systems for infectious agents in xenotransplantation*

open access: yesXenotransplantation, EarlyView., 2020
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

Parvovirus-derived endogenous viral elements in two South American rodent genomes [PDF]

open access: yes, 2014
We describe endogenous viral elements (EVEs) derived from parvoviruses (family <i>Parvoviridae</i>) in the long-tailed chinchilla (<i>Chinchilla lanigera</i>) and degu (<i>Octodon degus</i>) genomes.

A paradigm for virus-host coevolution: sequential counter-adaptations between endogenous and exogenous retroviruses.

open access: yesPLoS Pathogens, 2007
Endogenous retroviruses (ERVs) are remnants of ancient retroviral infections of the host germline transmitted vertically from generation to generation. It is hypothesized that some ERVs are used by the host as restriction factors to block the infection ...

Complete genome sequences of two feline Leukemia virus subgroup B isolates with novel recombination sites [PDF]

open access: yes, 2013
It is generally accepted that all primary isolates of feline leukemia virus (FeLV) contain a subgroup A virus (FeLV-A) that is essential for transmission.
