The KRAB repressor domain can trigger de novo promoter methylation during mouse early embryogenesis

Patrick Aebischer, Didier Trono, Friedrich Beermann, Johan Jakobsson, Shuangqing Liao

The Krüppel-associated box (KRAB) domain is a transcriptional repression module responsible for the DNA binding-dependent gene silencing activity of hundreds of vertebrate zinc finger proteins. We previously exploited KRAB-mediated repression within the co ...

Interfering residues narrow the spectrum of MLV restriction by human TRIM5alpha

Didier Trono, Priscilla Turelli, Pierre Maillard, Séverine Reynard

TRIM5alpha is a restriction factor that limits infection of human cells by so-called N- but not B- or NB-tropic strains of murine leukemia virus (MLV). Here, we performed a mutation-based functional analysis of TRIM5alpha-mediated MLV restriction. Our resu ...

KRAB can repress lentivirus proviral transcription independently of integration site

Didier Trono, Isabelle Barde

The KRAB transcriptional repressor domain, commonly found in zinc finger proteins, acts by inducing the formation of heterochromatin. We previously exploited this property to achieve drug-regulated transgenesis and knock down by combining doxycycline-contr ...

A versatile tool for conditional gene expression and knockdown

Patrick Aebischer, Didier Trono, Marc-Olivier Sauvain

Drug-inducible systems allowing the control of gene expression in mammalian cells are invaluable tools for genetic research, and could also fulfill essential roles in gene- and cell-based therapy. Currently available systems, however, often have limited in ...

Multipotential nestin and Isl-1 positive mesenchymal stem cells isolated from human pancreatic islets

Didier Trono

Mesenchymal cells in the developing pancreas express the neural stem cell marker nestin and the transcription factor islet-1 (Isl-1). Using defined culture conditions we isolated on a single cell basis nestin producing cells from human pancreatic islets. T ...

DNA damage sensors ATM, ATR, DNA-PKcs, and PARP-1 are dispensable for human immunodeficiency virus type 1 integration

Didier Trono, Priscilla Turelli

Integration of a DNA copy of the viral RNA genome is a crucial step in the life cycle of human immunodeficiency virus type 1 (HIV-1) and other retroviruses. While the virally encoded integrase is key to this process, cellular factors yet to be characterize ...

Editing at the crossroad of innate and adaptive immunity

Didier Trono, Priscilla Turelli

Genetic information can be altered through the enzymatic modification of nucleotide sequences. This process, known as editing, was originally identified in the mitochondrial RNA of trypanosomes and later found to condition events as diverse as neurotransmi ...

Deficiency of ribosomal protein S19 in CD34+ cells generated by siRNA blocks erythroid development and mimics defects seen in Diamond-Blackfan anemia

Didier Trono, Thomas Kiefer

Diamond-Blackfan anemia (DBA) is a congenital red cell aplasia in which 25% of the patients have a mutation in the ribosomal protein S19 (RPS19) gene. To study effects of RPS19 deficiency in hematopoiesis we transduced CD34(+) umbilical cord blood (CB) and ...

Oncogenesis Following Delivery of a Nonprimate Lentiviral Gene Therapy Vector to Fetal and Neonatal Mice

Didier Trono

Gene therapy by use of integrating vectors carrying therapeutic transgene sequences offers the potential for a permanent cure of genetic diseases by stable vector insertion into the patients' chromosomes. However, three cases of T cell lymphoproliferative ...

Lentiviral vectors and antiretroviral intrinsic immunity

Didier Trono, Bastien Mangeat

Multicellular organisms have evolved under relentless attacks from pathogens, and as a consequence have spiked their genomes with numerous genes that serve to thwart these threats, notably through the building of the innate and adaptive arms of the immune ...

Development of cellular models for ribosomal protein S19 (RPS19)-deficient diamond-blackfan anemia using inducible expression of siRNA against RPS19

Didier Trono, Thomas Kiefer

Diamond-Blackfan anemia (DBA) is a congenital red cell aplasia in which 25% of the patients have a mutation in the ribosomal protein S19 (RPS19) gene. No models exist for RPS19-deficient DBA and the molecular pathogenesis is unknown. To establish an in vit ...

Harnessing HIV for therapy, basic research and biotechnology

Didier Trono

First described about a decade ago, lentiviral vectors ('lentivectors') have emerged as potent and versatile tools of gene transfer for basic and applied research and offer exciting perspectives for the field of gene therapy. In the clinic, HIV-based vecto ...

Transduction of CpG DNA-stimulated primary human B cells with bicistronic lentivectors

Didier Trono

Recently, using HIV-1-derived lentivectors, we obtained efficient transduction of primary human B lymphocytes cocultured with murine EL-4 B5 thymoma cells, but not of isolated B cells activated by CD40 ligation. Coculture with a cell line is problematic fo ...

Novel lentiviral vectors displaying "early acting cytokines" selectively promote survival and transduction of NOD/SCID repopulating human hematopoietic stem cells

Didier Trono

A major limitation of current lentiviral vectors (LVs) is their inability to govern efficient gene transfer into quiescent cells, such as human CD34+ cells that reside into G0 phase of the cell cycle and that are highly enriched in hematopoietic stem cells ...

Activity analysis of housekeeping promoters using self-inactivating lentiviral vector delivery into the mouse retina

Patrick Aebischer, Nicole Déglon, Didier Trono

For most retinal degeneration disorders, no efficient treatment exists to preserve photoreceptors (PRs) and, consequently, to maintain vision. Gene transfer appears to be a promising approach to prevent PR loss. In order to design adequate vectors to targe ...
