KRAB zinc finger protein-mediated control of transposon-embedded regulatory sequences from human germline to early embryos

Transposable elements (TEs), also called jumping genes, are genetic elements capable of changing their position within the genome of their host. They make up large fractions of genomes, including 45% of human DNA content, according to current estimates. S ...

Endogenous retroviruses drive KRAB zinc-finger protein family expression for tumor suppression

Didier Trono, Priscilla Turelli, Alexandre Coudray

Gene expression aberration is a hallmark of cancers, but the mechanisms underlying such aberrations remain unclear. Human endogenous retroviruses (HERVs) are genomic repetitive elements that potentially function as enhancers. Since numerous HERVs are epige ...

Recent advances on sputtered films with Cu in ppm concentrations leading to an acceleration of the bacterial inactivation

Juan Kiwi, Sami Rtimi

This review focuses on the acceleration of the bactericidal and fungicidal effects by uniform, adhesive Cu-based nanocomposites on textile and thin polymer surfaces. The acceleration of the bacterial inactivation kinetics mediated by Cu, TiO2/Cu and ZrO2-T ...

A modeling approach to estimate the solar disinfection of viral indicator organisms in waste stabilization ponds and surface waters

Tamar Kohn, Michael Jon Mattle

Sunlight is known to be a pertinent factor governing the infectivity of waterborne viruses in the environment. Sunlight inactivates viruses via endogenous inactivation (promoted by absorption of UVB sunlight by the virus) and exogenous processes (promoted ...

Drawing a fine line on endogenous retroelement activity

Didier Trono, Marc Samuel Friedli

Endogenous retroelements (EREs) are essential motors of evolution yet require careful control to prevent genomic catastrophes, notably during the vulnerable phases of epigenetic reprogramming that occur immediately after fertilization and in germ cells. Ac ...

TRIM28 is a corepressor that mediates transcriptional silencing by establishing local heterochromatin. Here, we show that deletion of TRIM28 in neural progenitor cells (NPCs) results in high-level expression of two groups of endogenous retroviruses (ERVs): ...

Influence of Temperature, VFA and pH on the inactivation of pathogens in anaerobic digestion of faecel sludge

Livia Jost

On-site sanitation technologies such as septic tanks are widely used in low- and middle-income countries. A comprehensive management of the accumulating faecal sludge (FS) is however missing in most contexts and uncontrolled disposal of FS results in serio ...

Dynamics of HIV Latency and Reactivation in a Primary CD4+T Cell Model

Jacques Fellay, Christian Axel Wandall Thorball, Amalio Telenti, Istvan Bartha, Julia di Iulio

HIV latency is a major obstacle to curing infection. Current strategies to eradicate HIV aim at increasing transcription of the latent provirus. In the present study we observed that latently infected CD4+ T cells from HIV-infected individuals failed to pr ...

Interplay of TRIM28 and DNA methylation in controlling human endogenous retroelements

Didier Trono, Priscilla Turelli, Julien Léonard Duc, Charlène Mireille Raymonde Raclot, Adamantia Kapopoulou, Flavia Marzetta

Reverse transcription-derived sequences account for at least half of the human genome. Although these retroelements are formidable motors of evolution, they can occasionally cause disease, and accordingly are inactivated during early embryogenesis through ...

De novo DNA methylation of endogenous retroviruses is shaped by KRAB-ZFPs/KAP1 and ESET

Didier Trono, Sonia Verp, Marc Samuel Friedli, Sandra Eloise Kjeldsen, Helen Mary Rowe

Endogenous retroviruses (ERVs) undergo de novo DNA methylation during the first few days of mammalian embryogenesis, although the factors that control the targeting of this process are largely unknown. We asked whether KAP1 (KRAB-associated protein 1) is i ...
