Full textSingle-molecule-like spectroscopy plays a major role in many domains, from fundamental physics to biology. In this framework, my dissertation focuses on instrumental and theoretical developments of two biological-related applications. The first experiment aims at characterizing the dynamics of calcium binding by the fluorescent calcium probe Oregon-green Bapta5N commonly employed in cell signaling analysis. To achieve it, I have developed an experimental set-up of fluorescence correlation spectroscopy that exhibits sensitivity close to that of single-molecule detection. Either monophotonic or biphotonic excitations can be used. I have investigated the several aspects of the photophysics of the probe and evaluated the interest and limitations of such an approach for future in-vivo measurements. The second one is devoted to the development of a semi-quantitative Fluorescent In-Situ Hybridization (FISH) technique for mapping gene expression in the adult drosophila brain. Two difficulties have to be solved. First, we succeeded in obtaining reproducible results with drosophila adult brain. Secondly, while most of the FISH protocols are not quantitative since they need a strong enzymatic, we achieved semi-quantitative detection of RNA probes. I will present results on a new approach for which enzymatic detection is replaced by a sensitive detection and a protocol which reduces autofluorescence contribution. Results will be presented for several genes in adult drosophila brain to validate the methods as well as an interesting application on a mental retardation disease. To conclude, I show that the method exhibits a single RNA sensitivity which opens the way to new applications

Full textInversions are structural chromosomal rearrangements formed when a chromosome breaks in two places and the fragments reverses orientation. The inversion is pericentric if the breaks occur on either side of the centromere, paracentric in other cases. Prevalence estimates in human population range from 0. 012% to 0. 07% for pericentrics and from 0,01% to 0,05% for paracentrics (McKinlay-Gardner et Sutherland, 2004). Usually, both para- and pericentric inversions are phenotypically harmless, but the presence of an inversion can occasionally lead to severe reproductive disorders due to spermatogenesis impairements and the production of genetically unbalanced gametes. Many cases of inversions have been described in humans as well as in other animal species. However, relatively few studies have reported meiotic segregation pattern analyses of inversions in males (for example Morel et al. 2007), and none were reported on domestic animals. Meiotic analyses of various inversions identified in the pig species, thanks to the national program of chromosomic control, have a double interest. The first is zootechnical. When an inversion is detected in a boar, the breeders are always advised to sacrifice the animal. However, it can be difficult to eliminate individuals with a high genetic value and then induce a lowering in the efficiency of selection programms. Using a prediction of the potential effects of rearrangements to advise the breeders seem to be a good alternative. One of the thesis purpose is then to create a predictive method based on the percentage of unbalanced gametes in semen samples. The second interest is more linked to basic research. Indeed, it can be difficult to acquire knowledge on meiotic behaviour of chromosomal rearrangements in Man due to technical and/or ethical reasons. For example, little is known on an " sex " effect on meitoic behaviour during meiosis for inversion carriers. The use of an animal model (like the pig species) is a great opportunity to analyze the meiotic behaviour of chromosomes in inversion carriers, and then to have a better understanding on not well documented domains. That is why an other purpose of this thesis was to carried a comparative study of meotic segregations in males and females carriers of the same anomaly, and then determine a potential " sex " effect. Meotic segregation pattern analyses were carried out using the SpermFISH technique (fluorescent in situ hybridization on decondensed sperm nuclei) for males, and FISH on metaphase II oocytes matured in vitro for females. In both cases, molecular probes (Bacterial Artificial Chromosome) were used. Studies of pairing behaviour were carried out on testicular samples of an inversion of chromosome 4 carrier, using immunocytological techniques (use of specific antibodies against proteins of interest). Meotic segregation pattern analyses were carried out for 7 inversions (different length of the inverted fragment and different type) : percentage of unbalanced gametes ranged from 0,6% to 4%, suggesting a limited impact on reproduction. Surprisingly, the length of the inverted fragment is not correlated to the proportion of unbalanced gametes (unlike in Man). Comparison of " male " and " female " segregation profiles for an inversion of chromosome 4 did not show either any difference concerning the production of unbalanced gametes (4% and 3,6% respectively). The gender of the carriers do not seem to be a major factor for the production of unbalanced gametes. Analyses of early stages of meiosis for a carrier of the same pericentric inversion showed a specific meiotic behaviour of the bivalent : a non homologous pairing of the inverted region was seen in more than 90% of the cells analysed. Moreover, crossing overs in the inverted region were relatively rare (5 % of the cells). This chromosomal behaviour explains the low recombination rate in the inverted region, and then the low proportion of unbalanced gametes produced (mean of 4%). These results have to be confirmed by other analyses. Studies of the early stages of meiosis in two carriers of pericentric inversions of chromosome 8 should allow in the future a better understanding of the meiotic behaviour for inversion carriers. Moreover, the use of new techniques, such as production of induced pluripotent stem cells (iPS), could allow, in the future, analyses of the whole male meiotic process in inversion carriers

Full textSince a few years, sensorial defects defined as earthy or musty odours have been detected in some wines of several French wine-producting regions like Beaujolais, Loire Valley and Bordeaux. All types of wines can be concerned. The molecule responsible for these defects is geosmin. It is produced very early in the vineyeards by micro-organisms present on the grapes. We also know that actinomycete bacteria, including the Streptomyces genus or fungi belonging to the Penicillium genus cans produce geosmin. We have developed methodological tools for an easy, quick, and early detection of the micro-organisms responsible for the production of the molecules causing the earthy defects in wines. The FISH method is used for the early detection of Streptomyces on grapes using the HGC probe. However, no Streptomyces has been detected with the FISH technique on our grapes'samples, even if they were probably there as they have been detected by classic mircrobiological methods. This Gan be caused by a large majority of fungal spores in the samples, masking the presence of these micro-organisms. Regarding the moulds, the detection of geosmin-producing species is not possible du to the lack of specific probes

Full textMultiple myeloma (MM) is a malignancy cf the terminally-differentiated B cells that accounts for 10% of ail hematological malignancies. Some chromosomal abnormalities are important prognostic factors. This study is a cytogenetic work on 94 MM patients between January 2000 and December 2005, using conventional and molecular cytognetics technics, like Fluorescence In Situ Hybridization (FISH) and 24 colours FISH. Thus, 65 patients revealed chromosome 1 abnormalities. These abnormalities were most frequently a loss of lp arm and a gain of lq arm; jumping translocations were observed in 6 patients. Moreover, twenty-two patients (39%) had an 1Gb! translocation, which were sometimes complex, 56% had 13q14 deletion and 99% had l7pl3 deletion. Finally, we compared two MM karyotypes with their plasma cell leukemia karytopes. Statisticai study was used on cytogenetic, clinical and biological data and revealed the importance of ploidy. Some patients presented very complex karyotypes, probably increasing the pathology. This study showed loci of interest and proposed genetic deregulations hypotheses. Setter mechanism knowledge about MM evolution will permit to propose better treatments for this fatal pathology

Full textMRNA localization was discovered in 1983 in ascidian oocytes and early embryos. Since then many examples of localized RNAs have been found in many organisms, including plants, yeast, fungi, insects, fish and mammals. Localized mRNAs contribute to many biological functions, such as embryonic patterning, asymmetric cell division, cell migration, signaling, neuronal plasticity and others…Until now, only few studies analyzed RNA localization in a systematic manner. Three of them were done in Drosophila, during embryogenesis, oogenesis or larval stage and analyzed around 16000 mRNAs in total. The two other studies were done in mammalian cells and analyzed nearly 1000 mRNAs each. These studies opened a door and raised questions regarding the importance of mRNA localization in human cells and its implication in different biological processes. The goal of my thesis was thus to increase the throughput of single molecule FISH techniques (smFISH) and to study mRNA localization in HeLa cells in a systematic manner.One limitation in smFISH is the cost of the fluorescent oligonucleotide probes, which limits the number of mRNAs that can be analyzed. Therefore, I developed an alternative protocol in which probes for many genes were synthesized as a pool of oligonucleotides (40 per gene in average, more than 12000 in total). Gene-specific probes were then amplified by PCR and converted into single strand by in vitro transcription. I generated a complete protocol, starting from probe design and up to image acquisition. I was interested in studying cell cycle genes. Indeed, cell cycle genes have been extensively studied at the protein level but little is known concerning the localization of their mRNAs. During mitosis, cells go through important morphological modifications and local translation could be a mean of achieving protein localization. This screen is ongoing.In parallel to these experiments, I performed a smFISH based screen on 100 randomly chosen genes and 50 regulators of the G2/M transition of the cell cycle, using a traditional smFISH protocol. In this set-up, I took advantage of a library of HeLa cell lines, in which each cell line contains a bacterial artificial chromosome with the gene of interest tagged with GFP. Therefore, using oligonucleotides hybridizing to the GFP sequence, I could use the same probe set to study the localization of all the tagged mRNAs. A further advantage is that protein localization could be assessed simultaneously. My results indicate that two mRNAs showed a specific localization when screening 100 random genes, and 16 mRNAs among the 50 regulators of the G2/M transition. These mRNAs belong to five localization classes: "blobs", which are cytoplasmic mRNA aggregates; "clusters", which are areas of high local mRNA concentration but where individual mRNA can still be resolved; "nuclear envelope", where mRNAs concentrate around the nuclear envelope; "spindle", which are mRNAs accumulating on the cell division apparatus during mitosis, “spots" which are cytoplasmic mRNA aggregates where individual mRNA can’t be resolved and are bigger than blobs. Interestingly, colocalization between mRNA and GFP, which suggests local translation, was only found for 1 mRNA.These random and targeted screens performed at small-scale show an unexpected frequency and diversity in mRNA localization patterns, therefore pointing to new functions related to this process. This will stimulate future studies aiming at performing screenings at a higher scale
