The corrinoid metabolism in desulfitobacterium hafniense - genetic and regulatory aspects

Christof Holliger, Julien Maillard, Emmanuelle Rohrbach, Aurélie Duret

Corrinoids (e.g. vitamin B12, cobalamin) represent a family of complex organometallic cofactors essential to the metabolism of microorganisms, animal and humans, and are involved in several enzymes such as isomerases, methyltransferases and reductive dehal ...

Impact of copy number variations (CNVs) on long-range gene regulation at the HoxD locus

Denis Duboule

Copy number variations are genomic structural variants that are frequently associated with human diseases. Among these copy number variations, duplications of DNA segments are often assumed to lead to dosage effects by increasing the copy number of either ...

A function for all posterior Hoxd genes during digit development?

Denis Duboule, Saskia Joëlle Delpretti Anex, Jozsef Zakany

Background: Four posterior Hoxd genes, from Hoxd13 to Hoxd10, are collectively regulated during the development of tetrapod digits. Besides the well-documented role of Hoxd13, the function of the neighboring genes has been difficult to evaluate due to the ...

Widespread occurrence of non-canonical transcription termination by human RNA polymerase III

Human RNA polymerase (Pol) III-transcribed genes are thought to share a simple termination signal constituted by four or more consecutive thymidine residues in the coding DNA strand, just downstream of the RNA 3'-end sequence. We found that a large set of ...

Chromosome Conformation Capture Uncovers Potential Genome-Wide Interactions between Human Conserved Non-Coding Sequences

Didier Trono, Isabelle Barde, Sonia Verp, Marc Samuel Friedli

Comparative analyses of various mammalian genomes have identified numerous conserved non-coding (CNC) DNA elements that display striking conservation among species, suggesting that they have maintained specific functions throughout evolution. CNC function ...

Epigenetic Modification of the FMR1 Gene in Fragile X Syndrome Is Associated with Differential Response to the mGluR5 Antagonist AFQ056

Nouchine Hadjikhani, Fei Chen

Fragile X syndrome (FXS) is an X-linked condition associated with intellectual disability and behavioral problems. It is caused by expansion of a CGG repeat in the 5' untranslated region of the fragile X mental retardation 1 (FMR1) gene. This mutation is a ...

A gene-rich, transcriptionally active environment and the pre-deposition of repressive marks are predictive of susceptibility to KRAB/KAP1-mediated silencing

Didier Trono, Jacques Rougemont, Giovanna Ambrosini, Nadine Fournier, Philipp Bucher, Adamantia Kapopoulou, Annamaria Kauzlaric, Anna Claire Groner, Sylvain Meylan

ABSTRACT: BACKGROUND: KRAB-ZFPs (Kruppel-associated box domain-zinc finger proteins) are vertebrate-restricted transcriptional repressors encoded in the hundreds by the mouse and human genomes. They act via an essential cofactor, KAP1, which recruits effec ...

Estimating the net contribution of IL28B variation to spontaneous hepatitis C virus clearance

Jacques Fellay, Amalio Telenti, Julia di Iulio

The identification of associations between IL28B variants and spontaneous clearance of hepatitis C virus (HCV) raises the issues of causality and of the net contribution of host genetics to the trait. To estimate more precisely the net effect of IL28B gene ...

Unique Cell-Type-Specific Distributions and Functions of Brain MicroRNAs

Ana Jovicic

MicroRNAs (miRNAs) are small non-coding RNAs involved in post-transcriptional regulation of gene expression. The first miRNA was discovered less than 20 years ago in the context of studying Caenorabditis elegans development. The discovery of the second miR ...

Structural and functional differences in the long non-coding RNA hotair in mouse and human

Denis Duboule, Patrick Schorderet

Long non-coding RNAs regulate various biological processes such as dosage compensation, imprinting, and chromatin organization. HOTAIR, a paradigm of this new class of RNAs, is localized within the human HOXC gene cluster and was shown, in human cells, to ...
