Transcriptome mining reveals diversity and evolution of circulating and endogenous amphibian retroviruses

Retrovirology
Background The evolutionary history of retroviruses and their impact on vertebrate evolution remains poorly understood, particularly in non-mammalian hosts.

Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

Cancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.

Vaccination directed against the human endogenous retrovirus-K envelope protein inhibits tumor growth in a murine model system [PDF]

, 2013
Human endogenous retrovirus (HERV) genomes are chromosomally integrated in all cells of an individual. They are normally transcriptionally silenced and transmitted only vertically. Enhanced expression of HERV-K accompanied by the emergence of anti-HERV-K-

Endogenous retroviruses of non-avian/mammalian vertebrates illuminate diversity and deep history of retroviruses. [PDF]

PLoS Pathogens, 2018
The deep history and early diversification of retroviruses remains elusive, largely because few retroviruses have been characterized in vertebrates other than mammals and birds.

Human APOBEC3G suppresses homologous recombination and LIG4‐independent end joining in DNA double‐strand break repair

The FEBS Journal, EarlyView.
Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.

The evolutionary dynamics of endogenous retroviruses

Trends in Microbiology, 2005
Endogenous retroviruses (ERVs) are vertically transmitted intragenomic elements derived from integrated retroviruses. ERVs can proliferate within the genome of their host until they either acquire inactivating mutations or are lost by recombinational deletion.

An Integrated Analysis of Manganese Metabolism‐Related Genes and Their Association With Biomarkers, Immune Infiltration, and Clinical Subtypes in Alzheimer's Disease

Genes, Brain and Behavior, Volume 25, Issue 5, October 2026.
This study investigates the role of manganese metabolism in Alzheimer's disease (AD) pathogenesis. Using integrated bioinformatics and machine learning, four core manganese‐related diagnostic genes (TSPO, PTBP1, GLO1, ACACB) were identified, showing high diagnostic accuracy. The analysis also revealed significant immune microenvironment alterations and

Host Control of Insect Endogenous Retroviruses: Small RNA Silencing and Immune Response

Viruses, 2014
Endogenous retroviruses are relics of ancient infections from retroviruses that managed to integrate into the genome of germline cells and remained vertically transmitted from parent to progeny.

Expanding the Fish‐Brain Invitrome With the Senegalese Sole SsB‐1 Cell Line—A Versatile Model for Neurotropic Virus Research

Journal of Fish Diseases, Volume 49, Issue 10, October 2026.
ABSTRACT Cell lines are essential tools for studying animal physiology and immunopathology, reducing the use of live animals and supporting the 3Rs principle of reduction, refinement, and replacement. The Senegalese sole (Solea senegalensis), a relevant species for Spanish aquaculture diversification, lacks established in vitro models. We developed SsB‐

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, Volume 20, Issue 9, Page 2220-2242, September 2026.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
