Virophages of Giant Viruses: An Update at Eleven

open access: yesViruses, 2019
The last decade has been marked by two eminent discoveries that have changed our perception of the virology field: The discovery of giant viruses and a distinct new class of viral agents that parasitize their viral factories, the virophages.

Towards meta-evolution via embodiment in artificial chemistries [PDF]

open access: yes, 2012
Meta-evolution, the ability to generate novel ways of generating novelty, is one of the major goals of Artificial Life research. Biological systems can be seen to perform open-ended meta-evolution, but unfortunately this has proved very difficult to ...

A billion years arms-race between viruses, virophages, and eukaryotes

open access: yeseLife, 2023
Bamfordviruses are arguably the most diverse group of viruses infecting eukaryotes. They include the Nucleocytoplasmic Large DNA viruses (NCLDVs), virophages, adenoviruses, Mavericks and Polinton-like viruses.

Role of the R349 Gene and Its Repeats in the MIMIVIRE Defense System

open access: yesFrontiers in Microbiology, 2019
MIMIVIRE is a defense system described in lineage A Mimivirus (Mimiviridae family) that mediates resistance against Zamilon virophage. It is composed of putative helicase and nuclease associated with a gene of unknown function called R349, which contains

Virophages and Their Interactions with Giant Viruses and Host Cells

open access: yesProteomes, 2018
Virophages are small dsDNA viruses that were first isolated in association with some giant viruses (GVs), and then found in metagenomics samples. They encode about 20–34 proteins.

Polinton-like viruses are abundant in aquatic ecosystems

open access: yesMicrobiome, 2021
Background Polintons are large mobile genetic elements found in the genomes of eukaryotic organisms that are considered the ancient ancestors of most eukaryotic dsDNA viruses.

A systematic approach to cancer: evolution beyond selection

open access: yesClinical and Translational Medicine, Volume 6, Issue 1, December 2017., 2017
AbstractCancer is typically scrutinized as a pathological process characterized by chromosomal aberrations and clonal expansion subject to stochastic Darwinian selection within adaptive cellular ecosystems. Cognition based evolution is suggested as an alternative approach to cancer development and progression in which neoplastic cells of differing ...

Pantanal virophage: a new virophage species associated with a moumouvirus and a transpoviron, expanding the genus Sputnikvirus

open access: yesJournal of Virology
Amoeba-infecting giant viruses, such as mimiviruses, challenged paradigms of virology since their discovery. Their extensive and complex genomes and particle structures can interact with virophages and transpovirons, revealing unique aspects of the viral
