Towards improving full-length ribosome density prediction by bridging sequence and graph-based representations

Pierre Vandergheynst, Felix Naef, Cédric Gobet, Francesco Craighero, Mohan Vamsi Nallapareddy

Translation elongation plays an important role in regulating protein concentrations in the cell, and dysregulation of this process has been linked to several human diseases. In this study, we use data from ribo-seq experiments to model ribosome densities, ...

Ribo-DT: An automated pipeline for inferring codon dwell times from ribosome profiling data

Felix Naef, Cédric Gobet

Protein synthesis is an energy consuming process characterised as a pivotal and highly regulated step in gene expression. The net protein output is dictated by a combination of translation initiation, elongation and termination rates that have remained dif ...

Wnt5a promotes hippocampal postsynaptic development and GluN2B-induced expression via the eIF2 alpha HRI kinase

Eva Ramos Fernandez

Wnt signaling plays a key role in neurodevelopment and neuronal maturation. Specifically, Wnt5a stimulates postsynaptic assemblies, increases glutamatergic neurotransmission and, through calcium signaling, generates nitric oxide (NO). Trying to unveil the ...

Robust landscapes of ribosome dwell times and aminoacyl-tRNAs in response to nutrient stress in liver

Felix Naef, Cédric Gobet, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Nagammal Neelagandan

Translation depends on messenger RNA (mRNA)-specific initiation, elongation, and termination rates. While translation elongation is well studied in bacteria and yeast, less is known in higher eukaryotes. Here we combined ribosome and transfer RNA (tRNA) pr ...

Multilevel regulation of the glass locus during Drosophila eye development

Bart Deplancke, Michael Vincent Frochaux, Abhishek Kumar Mishra

Development of eye tissue is initiated by a conserved set of transcription factors termed retinal determination network (RDN). In the fruit fly Drosophila melanogaster, the zinc-finger transcription factor Glass acts directly downstream of the RDN to contr ...

The fitness landscape of the codon space across environments

Jeffrey David Jensen, Claudia Bank, Sebastian Matuszewski

Fitness landscapes map the relationship between genotypes and fitness. However, most fitness landscape studies ignore the genetic architecture imposed by the codon table and thereby neglect the potential role of synonymous mutations. To quantify the fitnes ...

Role of Cnot6l in maternal mRNA turnover

Jun Ma, Radek Jankele

Removal of poly(A) tail is an important mechanism controlling eukaryotic mRNA turnover. The major eukaryotic deadenylase complex CCR4-NOT contains two deadenylase components, CCR4 and CAF1, for which mammalian CCR4 is encoded by Cnot6 or Cnot6l paralogs. W ...

Circadian clock- and feeding-dependent regulation of translation initiation and elongation in the liver

Cédric Gobet

Circadian rhythms allow organisms to anticipate and adapt to periodic environmental changes related to the day-night cycle. These rhythms originate from a genetic network ticking in almost every cell of our body and the coordination between different organ ...

Rae1/YacP, a new endoribonuclease involved in ribosome-dependent mRNA decay in Bacillus subtilis

Jérémie Piton

The PIN domain plays a central role in cellular RNA biology and is involved in processes as diverse as rRNA maturation, mRNA decay and telomerase function. Here, we solve the crystal structure of the Rae1 (YacP) protein of Bacillus subtilis, a founding mem ...

Olfactory receptor pseudo-pseudogenes

Matteo Dal Peraro, Benoîte Bargeton

Pseudogenes are generally considered to be non-functional DNA sequences that arise through nonsense or frame-shift mutations of protein-coding genes(1). Although certain pseudogene-derived RNAs have regulatory roles(2), and some pseudogene fragments are tr ...

Role of APOBEC3F Gene Variation in HIV-1 Disease Progression and Pneumocystis Pneumonia

Jacques Fellay, Istvan Bartha, Christian Axel Wandall Thorball

Human APOBEC3 cytidine deaminases are intrinsic resistance factors to HIV-1. However, HIV-1 encodes a viral infectivity factor (Vif) that degrades APOBEC3 proteins. In vitro APO-BEC3F (A3F) anti-HIV-1 activity is weaker than A3G but is partially resistant ...

Searching the coding region for microRNA targets

Jiri Vanicek, Ray Marcel Marin Florez, Miroslav Sulc

Finding microRNA targets in the coding region is difficult due to the overwhelming signal encoding the amino acid sequence. Here, we introduce an algorithm (called PACCMIT-CDS) that finds potential microRNA targets within coding sequences by searching for ...

Updating and curating metabolic pathways of TB

Jocelyne Lew

The sequencing of complete genomes has accelerated biomedical research by providing information about the overall coding capacity of bacterial chromosomes. The original TB annotation resulted in putative functional assignment of similar to 60% of the genes ...

Highly Specific Methods for the Prediction of Genes Regulated by MicroRNAs

Ray Marcel Marin Florez

MicroRNAs (miRNAs) comprise a large set of short noncoding RNAs that bind to messenger RNAs (mRNAs) to reduce their translation into functional proteins. Computational prediction of miRNA targets is the first stage in the discovery and validation of new re ...

WebPrInSeS: automated full-length clone sequence identification and verification using high-throughput sequencing data

Bart Deplancke, Andreas Massouras, Frederik Decouttere

High-throughput sequencing (HTS) is revolutionizing our ability to obtain cheap, fast and reliable sequence information. Many experimental approaches are expected to benefit from the incorporation of such sequencing features in their pipeline. Consequently ...

Conserved elements within open reading frames of mammalian Hox genes

Denis Duboule

A recent study in BMC Evolutionary Biology shows that many of the open reading frames in mammalian Hox genes are more conserved than expected on the basis of their protein sequence. The presence of highly conserved DNA elements is thus not confined to the ...

Synthesis of modified nucleosides for the incorporation into tRNAs

Sébastien Porcher

More than 100 modified nucleosides have been found in naturally occurring RNA sequences. These modifications are involved in the correct folding, in the maintenance of the reading frame during translation and in the proper interaction with enzymes and prot ...

Promoter trapping reveals significant differences in integration site selection between MLV and HIV vectors in primary hematopoietic cells

Michele De Palma

Recent reports have indicated that human immunodeficiency virus (HIV) and murine leukemia virus (MLV) vectors preferentially integrate into active genes. Here, we used a novel approach based on genetic trapping to rapidly score several thousand integration ...
