Transcriptional Regulation of Endogenous Retroviruses and Their Misregulation in Human Diseases

open access: yesInternational Journal of Molecular Sciences, 2022
Endogenous retroviruses (ERVs), deriving from exogenous retroviral infections of germ line cells occurred millions of years ago, represent ~8% of human genome.

Endogenous Retroviruses and Placental Evolution, Development, and Diversity

open access: yesCells, 2022
The main roles of placentas include physical protection, nutrient and oxygen import, export of gasses and fetal waste products, and endocrinological regulation. In addition to physical protection of the fetus, the placentas must provide immune protection

Origin and Deep Evolution of Human Endogenous Retroviruses in Pan-Primates

open access: yesViruses, 2022
Human endogenous retroviruses (HERVs) are viral “fossils” in the human genome that originated from the ancient integration of exogenous retroviruses. Although HERVs have sporadically been reported in nonhuman primate genomes, their deep origination in ...

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 ...

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.

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 ...

Endogenous retroviruses shape pluripotency specification in mouse embryos

open access: yesScience Advances
The smooth and precise transition from totipotency to pluripotency is a key process in embryonic development, generating pluripotent stem cells capable of forming all cell types.

Multiple groups of endogenous epsilon-like retroviruses conserved across primates [PDF]

open access: yes, 2014
Several types of cancer in fish are caused by retroviruses, including those responsible for major outbreaks of disease, such as walleye dermal sarcoma virus and salmon swim bladder sarcoma virus. These viruses form a phylogenetic group often described as

Morc3 silences endogenous retroviruses by enabling Daxx-mediated histone H3.3 incorporation

open access: yesNature Communications, 2021
Endogenous retroviruses (ERVs) comprise a significant portion of mammalian genomes. Although specific ERV loci feature regulatory roles for host gene expression, most ERV integrations are transcriptionally repressed by Setdb1-mediated H3K9me3 and DNA ...

Potential benefits and risks of clinical xenotransplantation [PDF]

open access: yes, 2012
The transplantation of organs and cells from pigs into humans could overcome the critical and continuing problem of the lack of availability of deceased human organs and cells for clinical transplantation.
