Full textThe 70 kDa Heat Shock Proteins (HSP70) are considered the most conserved members of the HSP family. These molecular chaperones are primordial to living beings, because of their implications in many cellular pathways and the management of multiple environmental stress factors (e. g., temperature, pollutants, salinity, radiations). Widely used in ecology as a biomarker of environmental stress, the HSP70 family is also a privileged therapeutic target for neurodegenerative diseases and cancers. In the cytosol, a wide variety of HSP70 is observed in few model species (Drosophila, human, yeast). Nevertheless, the diversity of cytosolic HSP70 remains unclear amongst the Arthropoda phylum, especially within decapods. The diversity studies of cytosolic HSP70 were based on 735 sequences from 198 arthropod species, including 142 sequences from decapods obtained during this work. Molecular phylogeny analyses revealed at least three distinct groups of HSP70 within arthropods, comprising several unrecognised subdivisions. This study proposes a new classification and an evolutionary model of cytosolic HSP70 amongst the Arthropoda phylum. The expression profiles observed in each group lead to reconsider the HSP70 classification according to their constitutive (HSC70) or inducible (HSP70) features. The observed structural specificities of genes and proteins, relative to each form of HSP70, will probably have to be linked to distinct interactions with cochaperones or other co-factors

Full textWolbachia are intracellular Gram(-) bacteria that are reproductive manipulators of many arthropods. In the isopod Armadillidium vulgare, the Wolbachia wVulC strain induces male feminization. Here, we characterized two vir operons which are expressed in all host tissues and which encode a type IV secretion system (T4SS) used to translocate bacterial effectors into host cytoplasm. Gene organization and sequence comparison in 37 Wolbachia strains highlighted the high conservation of both vir operons and their importance for the biology of the bacteria. We also identified in the on-going assembly of the wVulC genome, 66 ankyrin domain-encoding genes. Ankyrin motifs are known to mediate protein-protein interactions in eukaryotic organisms and thus are suggested to mediate in Wolbachia the interaction with host molecules. We showed that one of the three copies of the wVulC pk2 gene is only expressed in feminizing strains but not in the three strains inducing cytoplasmic incompatibility in terrestrial isopods. The associated Pk2 protein could be involved in male feminization. We thus tested the interaction between three T4SS proteins and five ankyrins (including Pk2) via the yeast twohybrid and CRAfT (Cre-recombinase Reporter Assay for Translocation) methods. None of the five ankyrin proteins were revealed to be secreted by the wVulC strain. Nevertheless, this promising approach may enable us to identify Wolbachia effectors

Full textSpirulina is a high nutritive foodstuff which contains 55% to 65% of proteins. The quality of the dry product depends on drying methods. Thus, in this work, the convective drying method was investigated as concern process parameters influence and the influence of several drying methods on the biochemical quality of dried product. An air-lift photobioreactor of 40 L volume was built in order to obtain an important production of fresh biomass for the drying experiments. It was possible characterize its productivity and the spirulina cultures growth rate. The shrinkage behaviour of the biomass with convective drying was characterized for the initial samples shaped as cylinders and thin layers. The drying rate was corrected by taking of account the shrinkage. This revealed the existence of a constant drying rate periods for cylinders of various initial diameters. The Characteristic Drying Curve (CDC) and the values of the water mean diffusion coefficient were estimated for the cylinders. The proteins and total sugars contents on dried samples were analyzed after different drying methods by convective, infra-red, atomization, and freeze-drying. The best drying method for the recovery of proteins and total sugars contents was freeze-drying

Full textHematophagous arthropods such as mosquitoes, ticks, and fleas are of significant importance in public health because of their ability to transmit major diseases to humans and animals. Vector control and epidemiological vector surveillance are essential in the strategy of combating vector-borne diseases. The latter is successful only by a correct and precise identification of the vectors. Thus in this work, we have developed and improved the protocols of samples preparation for the identification of adult mosquitoes and their aquatic stages, ticks, and fleas by MALDI-TOF MS. This tool has been already distinguished as being reliable for the arthropods identification. The second part of our work consisted in the application of these protocols on mosquito larvae collected in the field during an entomological investigation carried out in the city of Marseille. In this study, the relevance and reliability of MALDI-TOF MS for the identification of mosquito larvae collected in the field were verified. Finally, we carried out the inventory of the viral communities of three mosquito species collected in Marseille by metagenomics, which revealed the presence of numerous new viruses. All the results presented in this thesis emphasize that the use of innovative tools such as MALDI-TOF MS and metagenomics to study vectors and the agents they carry is a promising strategy that will contribute to the knowledge of zoonotic transmission cycles and the potential risks of the emergence of vector-borne diseases in human populations
Kossinova, Olga. "Insights into the selenocysteine incorporation mechanism in mammals." Strasbourg, 2011. http://www.theses.fr/2011STRA6221.
Full textThe amino acid selenocysteine is encoded by a UGA triplet which acts generally as a stop codon. A specialized machinery is used to incorporate this amino acid into selenoproteins, involving a specific stem-loop, termed SelenoCysteine Insertion Sequence (SECIS), and some protein factors. One of those is the SECIS Binding Protein 2 (SBP2), which is necessary for ribosome recognition of the UGA as the Sec codon. Using synthetic selenocysteine mRNAs and translational inhibitors, several steps of mRNA translation were analyzed. The data obtained allowed us to propose the following mechanism for selenocysteine insertion : during the transpeptidation step of elongation, SBP2 is bound to the ribosome; however, after transpeptidation, SBP2 leaves the ribosome and binds the SECIS in the pre-translocation step. We showed earlier that SBP2 binds specifically to the purified human 60S but not to the 40S ribosome subunits but the actual location was unknown. The SBP2•40S, SBP2•60S and SBP2•80S complexes were thus studied using crosslinking reagents. SBP2 did not crosslink to the 40S subunit in either the 40S•SBP2 or 80S•SBP2 complexes, correlating with the binding data. However, SBP2 crosslinks to the 60S subunit in either the free state or in the 80S ribosome. I next showed that the 28S rRNA contributes more to the crosslink than ribosomal proteins. This led us to use hydroxyl radical footprinting to study the molecular environment of SBP2 on the ribosome. According to the probing data, the binding of SBP2 to the human 60S subunit protects 2 helices in expansion segment 7 of the 28S rRNA. I proposed that the SBP2 binding site is located in the vicinity of the L7/L12 stalk
