Full textThe functional organisation of the nucleus depends on machineries that are distributed in domains named nuclear bodies. To understand how this distribution is regulated we have chosen the nucleolus as example. We have focused our attention on traffic and compartmentation of the rRNA processing machinery during interphase and mitosis. To follow proteins in living cells we have used microscopy technologies such as: FRAP, videomicroscopy and tdFLIM-FRET. A reversible system capable of disconnecting the processing from the transcription machineries during interphase permitted us to show that the processing machinery can be disconnected from the transcription sites and accumulates in nuclear masses originating from the nucleolar granular component. We named these granular masses. This reversible process permitted us to study reformation of the nucleolus. In control cells and in an assay using permeabilized cells set up in the laboratory, we have shown that nucleolar reformation depends on ATP hydrolysis and that CK2 is involved in nucleolar compartmentation. At the exit of mitosis, we have shown that early and late processing machineries pass through the same PNB. The convergence of the machineries in a single site could be at the origin of PNB formation. Furthermore, we have demonstrated that Nop52 and B23 interact in the same PNB. For this reason, we propose that PNB are preassembly platforms for rRNA processing complexes

Full textA kissing-complex is made of two hairpins with complementary loops. This kind of structure is known to participate in molecular recognition and is involved in a lot of gene regulation but also in all retrovirus dimerization process (for a review, see Brunel et al. , 2002). Some of the factors which determine the kissing-complex stability have already been studied (Gregorian & Crothers, 1995). Here after a preliminary reflexion about the kissing-complex topology, a study based on MD and UV monitored thermal denaturation experiments gets a deep insight into the kissing-complex structure and stability and brings a new way to aprehend this family of structures. Then, a MD study of the two DIS/DIS (Dimerization Initiating Site of HIV-1) kissing-complex structure helps to understand the dynamics and the topology of both duplexes. This study results in a proposal of a new and simple dimerization process

Full textRNA does not only play a role in the genetic information transfer between a gene and his protein. As mRNA, tRNA and rRNA are involved in protein synthesis. MiRNA, snRNA, snoRNA and other ncRNA are involved in the regulation of numerous biological processes such as plasmid replication, conjugation, transcription, translation, splicing and posttranscriptional modifications. RNA are able to form stem-loop structures, to interact via their loops with nucleic partners and to form loop-loop complexes so called kissing complexes. RNAI/RNAII kissing complexes enables the regulation of ColE1 plasmid replication in E. Coli. An RNA hairpin (aptamer R-0624) has been selected against the TAR element located at the end of the 5' UTR of the human immunodeficiency virus HIV-1 RNA. The artificial R-0624/TAR kissing complex inhibits the transactivation of the viral transcription. We identified RNA hairpins derived from the human genome which are able to generate kissing complexes with TAR or RNA hairpins targets containing RNGG, RYRY or YUNR loop sequences. Those kissing complexes could be responsible for natural or artificial regulations of human genes. In this work, genomic SELEX (Systematic Evolution of Liganfs by Exponential enrichment) has been carried for the 1rst time for fishing RNA/RNA interactions and directed against target RNA libraries

Full textIn contrast to proteins, there are relatively few experimental and computational studies on RNAs. This is likely to change, however, due to the discovery that RNA molecules fulfil a considerable diversity of biological tasks, including, aside from its encoding and translational activity, also enzymatic and regulatory functions. Despite the simplicity of its four-letter alphabet, RNAs are able to fold into a wide variety of tertiary structures where dynamic conformational ensembles appear also to be essential for understanding their functions. In spite of constant experimental efforts and theoretical developments, the gap between sequences and 3D structures is increasing, and our lmowledge of RNA flexibility is still limited at an atomic level of detail. In this thesis, I present improvements to the HiRE-RNA model, and folding simulations that were performed with it. After presenting the computational methods used to sample the energy landscapes of RNA and the experimental methods providing information about RNA structures, I present the RNA topologies and the structural data I used to improve the model, and to study RNA folding. The improvements of HiRE-RNA in version 2 and version 3 are then described, as well as the simulations performed with each version of the model

Full textH/ACA RNAs are small nuclear RNAs that have many different functions in the cell. They are guide RNAs for the conversion of the uridine into pseudouridine of ribosomal RNAs and spliceosomal snRNAs. We showed that box H/ACA RNAs directing modifications of spliceosomal snRNAs carry a special signal that direct these box H/ACA RNAs into Cajal bodies. This signal is also present in the telomerase RNA that accumulates in Cajal bodies. With fluorescent microscopy, we were able to propose that Cajal bodies may deliver telomerase RNA at a subset of telomeres in S phase cells. Finally, our work on the expression and processing of box H/ACA RNAs revealed that splicing and assembly of box H/ACA RNP particles are two independent molecular events in human cells

Full textA fluctuating environment is a powerful mean of selection for living organisms, which evolved complex signaling networks to integrate these variations and direct swift and efficient cellular responses. The aim of my work is the identification and characterization of molecular mechanisms involved in the tolerance of replicative stress and DNA damage. First, we show that changes in dNTP pools affect several aspects of replication dynamics in budding yeast. dNTP levels are limiting for normal S-phase progression and determine the temporal program of replication during a replicative stress. Interestingly, we also observed that chromosomal instability (CIN) mutants display expanded dNTP pools due to the constitutive activation of the DNA damage checkpoint. Since increased dNTP levels promote forks progression in the presence of DNA lesions, we propose that CIN mutants adapt to chronic replicative stress by upregulating dNTP pools. Secondly, we bring new lights on the role of Crt10 in vivo, which has been initially identified as a negative regulator of Ribonucleotide Reductase (RNR) genes expression. Deletion of CRT10 neither leads to expanded dNTP pools, nor to a massive deregulation of RNR genes, although crt10Δ cells exhibit faster fork progression. The crt10Δ mutant accumulates at the G1/S transition and exhibits a strong defect of origin firing that could account for its replication phenotype. Moreover, we observed a global decrease in ribosome biogenesis in crt10Δ. The physical interaction of Crt10 with several members of the ribosome biogenesis pathway and its role in the Rtt101-Mms1 complex suggest that Crt10 may regulate ribosome levels in vivo. At last, we identified MRX (Mre11-Rad50-Xrs2) as a bona fide member of the transcription termination of non-coding RNA (ncRNA). ChIP-seq reveals that MRX localized at the same loci than the Nrd1-Nab3-Sen1 complex in vegetative growth. rad50Δ cells exhibit transcriptional read-through and upregulation of unstable cryptic transcripts (CUTs) leading to a misregulation of their associated gene. Finally, MRX seems to be involved in the resolution of branched structures emanating from collision between transcription and replication machineries, as it is the case for Sen1
