Extent and Patterns of MGMT Promoter Methylation in Glioblastoma- and Respective Glioblastoma-Derived Spheres

Purpose: Quantitative methylation-specific tests suggest that not all cells in a glioblastoma with detectable promoter methylation of the O6-methylguanine DNA methyltransferase (MGMT) gene carry a methylated MGMT allele. This observation may indicate cell ...

KRAB-Zinc Finger Proteins and KAP1 Can Mediate Long-Range Transcriptional Repression through Heterochromatin Spreading

Didier Trono, Giovanna Ambrosini, Nadine Fournier, Philipp Bucher, Anna Claire Groner, Nicolas Dénervaud, Sylvain Meylan

Krüppel-associated box domain-zinc finger proteins (KRAB-ZFPs) are tetrapod-specific transcriptional repressors encoded in the hundreds by the human genome. In order to explore their as yet ill-defined impact on gene expression, we developed an ectopic rep ...

Relationship between estrogen receptor alpha location and gene induction reveals the importance of downstream sites and cofactors

Felix Naef, Mauro Delorenzi

BACKGROUND: To understand cancer-related modifications to transcriptional programs requires detailed knowledge about the activation of signal-transduction pathways and gene expression programs. To investigate the mechanisms of target gene regulation by hum ...

Functional analysis and structural modeling of human APOBEC3G reveal the role of evolutionarily conserved elements in the inhibition of human immunodeficiency virus type 1 infection and Alu transposition

Didier Trono, Priscilla Turelli, Bastien Mangeat, Olivier Michielin

Retroelements are important evolutionary forces but can be deleterious if left uncontrolled. Members of the human APOBEC3 family of cytidine deaminases can inhibit a wide range of endogenous, as well as exogenous, retroelements. These enzymes are structura ...

Characterization of mouse Dactylaplasia mutations: a model for human ectrodactyly SHFM3

Denis Duboule, Marc Samuel Friedli

SHFM3 is a limb malformation characterized by the absence of central digits. It has been shown that this condition is associated with tandem duplications of about 500 kb at 10q24. The Dactylaplasia mice display equivalent limb defects and the two correspon ...

Contextual suppression and protection in schizophrenic patients

Michael Herzog, Maya Roinishvili

INTRODUCTION: Contextual processing is often strongly deteriorated in schizophrenic patients as found, for example, in higher cognitive as well as lower visual paradigms. In visual detection tasks, impoverished contextual facilitation was attributed to abe ...

In Drosophila melanogaster the COM Locus Directs the Somatic Silencing of Two Retrotransposons through both Piwi-Dependent and -Independent Pathways

Background. In the Drosophila germ line, repeat-associated small interfering RNAs (rasiRNAs) ensure genomic stability by silencing endogenous transposable elements. This RNA silencing involves small RNAs of 26-30 nucleotides that are mainly produced from t ...

Model Structure of Human APOBEC3G

Didier Trono, Bastien Mangeat, Amalio Telenti, Olivier Michielin

BACKGROUND: APOBEC3G (apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like 3G) has antiretroviral activity associated with the hypermutation of viral DNA through cytosine deamination. APOBEC3G has two cytosine deaminase (CDA) domains; the catal ...

A beta 42-driven cerebral amyloidosis in transgenic mice reveals early and robust pathology

Tristan Bolmont

We have generated a novel transgenic mouse model on a C57BL/ 6J genetic background that coexpresses KM670/ 671NL mutated amyloid precursor protein and L166P mutated presenilin 1 under the control of a neuron- specific Thy1 promoter element ( APPPS1 mice). ...

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 ...
