Abstract
Murine norovirus (MNV) infection results in a late translation shutoff that is proposed to contribute to the attenuated and delayed innate immune response observed both in vitro and in vivo. Recently, we further demonstrated the activation of the α subunit of eukaryotic initiation factor 2 (eIF2α) kinase GCN2 during MNV infection, which has been previously linked to immunomodulation and resistance to inflammatory signaling during metabolic stress. While viral infection is usually associated with activation of double-stranded RNA (dsRNA) binding pattern recognition receptor PKR, we hypothesized that the establishment of a metabolic stress in infected cells is a proviral event, exploited by MNV to promote replication through weakening the activation of the innate immune response. In this study, we used multi-omics approaches to characterize cellular responses during MNV replication. We demonstrate the activation of pathways related to the integrated stress response, a known driver of anti-inflammatory phenotypes in macrophages. In particular, MNV infection causes an amino acid imbalance that is associated with GCN2 and ATF2 signaling. Importantly, this reprogramming lacks the features of a typical innate immune response, with the ATF/CHOP target GDF15 contributing to the lack of antiviral responses. We propose that MNV-induced metabolic stress supports the establishment of host tolerance to viral replication and propagation. IMPORTANCE During viral infection, host defenses are typically characterized by the secretion of proinflammatory autocrine and paracrine cytokines, potentiation of the interferon (IFN) response, and induction of the antiviral response via activation of JAK and Stat signaling. To avoid these and propagate, viruses have evolved strategies to evade or counteract host sensing. In this study, we demonstrate that murine norovirus controls the antiviral response by activating a metabolic stress response that activates the amino acid response and impairs inflammatory signaling. This highlights novel tools in the viral countermeasures arsenal and demonstrates the importance of the currently poorly understood metabolic reprogramming occurring during viral infections.

Abstract
Response gene to complement-32 (RGC-32) activates cyclin-dependent kinase 1, regulates the cell cycle and is deregulated in many human tumours. We previously showed that RGC-32 expression is upregulated by the cancer-associated Epstein-Barr virus (EBV) in latently infected B cells through the relief of translational repression. We now show that EBV infection of naïve primary B cells also induces RGC-32 protein translation. In EBV-immortalised cell lines, we found that RGC-32 depletion resulted in cell death, indicating a key role in B cell survival. Studying RGC-32 translational control in EBV-infected cells, we found that the RGC-32 3′untranslated region (3′UTR) mediates translational repression. Repression was dependent on a single Pumilio binding element (PBE) adjacent to the polyadenylation signal. Mutation of this PBE did not affect mRNA cleavage, but resulted in increased polyA tail length. Consistent with Pumilio-dependent recruitment of deadenylases, we found that depletion of Pumilio in EBV-infected cells increased RGC-32 protein expression and polyA tail length. The extent of Pumilio binding to the endogenous RGC-32 mRNA in EBV-infected cell lines also correlated with RGC-32 protein expression. Our data demonstrate the importance of RGC-32 for the survival of EBV-immortalised B cells and identify Pumilio as a key regulator of RGC-32 translation.

Abstract
The role of m6A methylation of RNA has remained elusive for decades, but recent technological advances are now allowing the mapping of the m6A methylation landscape at nucleotide level. This has spurred an explosion in our understanding of the role played by RNA epigenetics in RNA biology. m6A modifications have been tied to almost every aspect of the mRNA life cycle and it is now clear that RNA virus genomes are subject to m6A methylation. These modifications play various roles in the viral replication cycle. This review will summarize recent breakthroughs concerning m6A RNA modification and their implications for cellular and viral RNAs.

Abstract
Viral proteins are frequently multifunctional to accommodate the high density of information encoded in viral genomes. Matrix (M) protein of negative-stranded RNA viruses such as Rhabdoviridae is one such example. Its primary function is virus assembly/budding but it is also involved in the switch from viral transcription to replication and the concomitant down regulation of host gene expression. In this study we undertook a search for potential rabies virus (RV) M protein's cellular partners. In a yeast two-hybrid screen the eIF3h subunit was identified as an M-interacting cellular factor, and the interaction was validated by co-immunoprecipitation and surface plasmon resonance assays. Upon expression in mammalian cell cultures, RV M protein was localized in early small ribosomal subunit fractions. Further, M protein added in trans inhibited in vitro translation on mRNA encompassing classical (Kozak-like) 5′-UTRs. Interestingly, translation of hepatitis C virus IRES-containing mRNA, which recruits eIF3 via a different noncanonical mechanism, was unaffected. Together, the data suggest that, as a complement to its functions in virus assembly/budding and regulation of viral transcription, RV M protein plays a role in inhibiting translation in virus-infected cells through a protein–protein interaction with the cellular translation machinery.

Abstract
It is now well established that Hepatitis C Virus (HCV) translation is driven by an Internal Ribosome Entry Site (IRES) resulting in cap-independent translation. Such a mechanism usually occurs with the help of IRES Associated Factors (ITAFs). Moreover, an important translational feature is likely conserved from the model of classical mRNA circularisation (5'-3' cross-talk), involving the HCV RNA highly structured 3' extremity called the 3'X region. This could bind several cellular factors and modulate the translation efficacy, at least in Rabbit Reticulocyte Lysate (RRL). In particular, polypyrimidine-binding proteins have been proposed to be potential HCV ITAFs, such as Polypyrimidine Tract Binding protein (PTB). However, contradictions still exist as to the role of PTB: its ability to bind both the HCV IRES and the 3'X region leads to the hypothesis that it could positively modulate IRES-driven translation in the presence of the X structure. Results of translational and PTB-binding studies of X mutant sequences led us to discredit PTB as protagonist of 3'X region stimulation on HCV IRES-driven translation. Moreover, competition assays of X RNA in trans on IRES-driven translation demonstrate the involvement of at least two stimulating factors and led to the conclusion that this mechanism is more complex than initially thought. Although we did not identify these factors, it is no longer doubtful that there is effectively a stimulating functional interaction between the HCV IRES and the 3'X region in RRL.

Abstract
The domain V within the internal ribosome entry segment (IRES) of poliovirus (PV) is expected to be important in its own neurovirulence because it contains an attenuating mutation in each of the Sabin vaccine strains. In this study, we try to find out if the results observed in the case of Sabin vaccine strains of PV can be extrapolated to another virus belonging to the same genus of enteroviruses but with a different tropism. To test this hypothesis, we used the coxsackievirus B3 (CVB3), known to be the most common causal agent of viral myocarditis. The introduction of the three PV Sabin-like mutations in the equivalent positions (nucleotides 484, 485, and 473) to the domain V of the CVB3 IRES results in significant reduced viral titer of the Sabin3-like mutant (Sab3-like) but not on those of Sab1- and Sab2-like mutants. This low titer was correlated with poor translation efficiency in vitro when all mutants were translated in rabbit reticulocyte lysates. However, elucidation by biochemical probing of the secondary structure of the entire domain V of the IRES of Sabin-like mutants reveals no distinct profiles in comparison with the wild-type counterpart. Prediction of secondary structure by MFOLD program indicates a structural perturbation of the stem containing the Sab3-like mutation, suggesting that specific protein-viral RNA interactions are disrupted, preventing efficient viral translation.

Abstract
In this work, we have investigated the role of CRM1/XPO1, a protein involved in specific export of proteins and RNA from the nucleus, in early Xenopus embryogenesis. The cloning of the Xenopus laevis CRM1, XCRM1, revealed remarkable conservation of the protein during evolution (96.7% amino acid identity between Xenopus and human). The protein and mRNA are maternally expressed and are present during early embryogenesis. However, our data show that the activity of the protein is developmentally regulated. Embryonic development is insensitive to leptomycin B, a specific inhibitor of CRM1, until the neurula stage. Moreover, the nuclear localization of CRM1 changes concomitantly with the appearance of the leptomycin B sensitivity. These data suggest that CRM1, present initially in an inactive form, becomes functional before the initiation of the neurula stage during gastrula-neurula transition, a period known to correspond to a critical transition in the pattern of gene expression. Finally, we confirmed the gastrula-neurula transition-dependent activation of CRM1 by pull-down experiments as well as by the study of the intracellular localization of a green fluorescent protein tagged with a nuclear export signal motif during early development. This work showed that the regulated activity of CRM1 controls specific transitions during normal development and thus might be a key regulator of early embryogenesis.

Abstract
We studied the p53 expression in the F4NW0 cell line. We found that this mutated p53 has a deletion of eight amino acids, between the conserved domains IV and V. Only one of the two alleles is expressed. It contains a single base mutation, which seems to promote the use of a cryptic splicing acceptor site, resulting in the observed deletion. The protein shows a cell cycle-dependent nuclear translocation: in G(1), it is exclusively cytoplasmic, and during the G(1)/S transition, it translocates into the nucleus. Nevertheless, different antibodies assayed revealed different patterns of localization.
