Full textDNA replication is regulated by the location and timing of replication initiation. Therefore, much effort has been invested in identifying and analyzing the sites of human replication initiation. However, the heterogeneous nature of eukaryotic replication kinetics and the low efficiency of individual initiation site utilization in metazoans has made mapping the location and timing of replication initiation in human cells difficult. A potential solution to the problem of human replication mapping is single-molecule analysis. However, current approaches do not provide the throughput required for genome-wide experiments. To address this challenge, we have developed Optical Replication Mapping (ORM), a high-throughput single-molecule approach to map newly replicated DNA and used it to map early initiation events in human cells. The single-molecule nature of our data, and a total of more than 2000-fold coverage of the human genome on 27 million fibers averaging ~300 kb in length, allow us to identify initiation sites and their firing probability with high confidence. In particular, for the first time, we are able to measure genome-wide the absolute efficiency of human replication initiation. We find that the distribution of human replication initiation is consistent with inefficient, stochastic initiation of heterogeneously distributed potential initiation complexes enriched in accessible chromatin. In particular, we find sites of human replication initiation are not confined to well-defined replication origins but are instead distributed across broad initiation zones consisting of many initiation sites. Furthermore, we find no correlation of initiation events between neighboring initiation zones. Although most early initiation events occur in early-replicating regions of the genome, a significant number occur in late replicating regions. The fact that initiation sites in typically late-replicating regions. The fact that initiation sites in typically late-replicating regions have some probability of firing in early S phase suggests that the major difference between initiation events in early and late replicating regions is their intrinsic probability of firing, as opposed to a qualitative difference in their firing-time distributions. Moreover, modeling of replication kinetics demonstrates that measuring the efficiency of initiation-zone firing in early S phase suffices to predict the average firing time of such initiation zones throughout S phase, further suggesting that the differences between the firing times of early and late initiation zones are quantitative, rather than qualitative. These observations are consistent with stochastic models of initiation-timing regulation and suggest that stochastic regulation of replication kinetics is a fundamental feature of eukaryotic replication, conserved from yeast to humans

Full textMy PhD focused on the molecular mechanisms governing initiation of DNA replication in vertebrates. I participated in the identification and characterization of origins of replication (ori) on 1% of the human genome. These ori have been identified in HeLa cells by quantification of short nascent strands, which are specific of replication initiation. We showed that a strong link exists between ori and CpG islands and that the association of ori with open chromatin marks like histone acetylation is dispensable for origin specification. Furthermore, no clear link emerges between ori density and the moment at which a genomic region replicates. I have also been interested in the licensing step which consists in the binding on the initiation sites of the Pre-replication complex (Pre-RC), in first place ORC (Origin recognition complex). Licensing takes place in the Gl phase of the cell cycle and only Pre-RC binding sites can be used as initiation sites. We chose to work with the avian DT40 cell line, able to perform homologous recombination at high frequency. I thus constructed cell lines which express tagged versions of the Orcl and Orc2 proteins and from the endogenous locus. I realized chromatin immunoprecipitations (ChIP) to identify their binding sites. We obtain small but coherent enrichments of Orcl at well known chicken ori. As these small enrichments complicate genome-wide approaches, we plan to repeat these experiments with elutriated cells in Gl phase in order to increase the ChIP enrichments

Full textThe present study deals with the replication of multiscale and multifunctional natural structures. These natural structures are wings of Morpho rhetenor, Morpho menelaus and Papilio ulysse butterflies, and those of Cicada orni cicada. Such structures are composed of smaller structures at different scales, from centimetre to nanometre, and to each of these scales is associated a property or a function. This we call multifunctionality. This multifunctionality is expected to become a property of our future objects or materials, and can be achieved by two different ways: to make the material(s) chemical composition of the object more complex (composite, hybrid organic-inorganic materials) and/or to make its architecture more complex (structuration). Although it is possible to achieve the first (chemical composition), we have so far been unable to successfully make multiscale structures with our current structuration techniques (lithography for example). Therefore, to increase the properties of a system characterised by a multiscale structure seen in nature, we have made replicas of the natural structures previously presented in inorganic materials (TiO2 and SiO2). That is to say, very different materials in comparison with the natural chitin-protein complex. To do this, three methods were used: a sol-gel solution deposition in the natural structures, a physical vapor deposition and a direct mineralization of the wings structure, which is inspired by natural biomineralization processes

Full textHaloferax volcanii is an archaea belonging to the phylum euryarchaeota and the class Halobacteriales. The mechanisms related to replication and repair in archaea are very similar to those found in eukaryotes, making H. volcanii a relevant model organisms for the study of replication and archaeal biology, especially since many genetic tools are available. Interestingly, all replication origins can be removed from the chromosome of H. volcanii, raising many questions about the mechanisms involved. Several hypotheses have been proposed on how this strain initiates its replication, either relying on recombination-dependent replication initiation or an origin-independent mechanism. In order to study these replication-related mechanisms, I have constructed a strain of H. volcanii able to incorporate thymidine analogues into DNA during its synthesis by deleting genes involved in the thymidine biosynthesis pathway. A short-time cultures of the strain in the presence of an analogue allows its incorporation in nascent DNA. By immunodetection of the analog coupled to fluorescence microscopy observation of whole cells, it is possible to investigate the localization of neosynthesized DNA,which reflect the regions where replication is active. These analyses revealed mainly 2 to 3 active replication regions per cell, without any particular location. These regions had already been observed by studying the localization of a key replication protein (RPA2) fused to the fluorescent green protein GFP, confirming its location in active replication areas. A surprising variability in the number of replication foci from one cell to another was observed, suggesting a probabilistic initiation of replication. It is also surprising to observe so few active replication areas compared to the high polyploidy of this strain. This raises the question of what these replication areas correspond to. For further understanding, I developed for H. volcanii molecular combing, to isolate individual DNA molecules and specifically reveal incorporated analogues to determine the number of copies of the chromosome that are being replicated, as well as the number of active origins on each of the copies. I have also developed time-lapse approach to track these regions over time by monitoring cell proliferation directly under the microscope

Full textThis work aimed at studying the Marek's Disease virus (MDV) UL17 protein which is homologous to the capsid and tegument protein of HSV-1 virus. For this purpose, we used a bacterial artificial chromosome (BAC) of the highly pathogenic MDV strain RB-1b to generate mutant viruses in which the UL17 gene was either deleted or tagged with the HA peptide. The results showed that MDV pUL17 is a phosphoprotein (82 kDa) essential for viral replication. During the infection, pUL17 localizes in the nuclear compartment. This nuclear localization is not an intrinsic property of pUL17 and implies a viral factor. The co-localization of pUL17 with the major capsid protein VP5 and its influence on the cellular distribution of the tegument protein pUL14 favour the hypothesis that pUL17 participates in early tegumentation
