Full textFish by-product valorization is an economic and environmental issue. For several years, scientific researches have shown that fish by-products contained active molecules for human health, as polyunsaturated fatty acids and peptides. The aim of this thesis was to evaluate the potential use of herring milt hydrolysates for human health, especially by evaluating their potential actions in physiological parameters involved in the metabolic syndrome and the effect of their separation by electrodialysis with ultrafiltration membrane (EDUF) for the production of bioactive fractions. First, we have demonstrated that the supplementation of three different herring milt hydrolysates in a high fat high sucrose diet in mice was able to modulate some physiological functions involved in the metabolic syndrome: improvement of glucose tolerance, increase of the total energy intake and protection against the Lactobacillus disappearance in the gut microbiota. Moreover, the hydrolysates decreased the inflammation induction in macrophages stimulated with LPS at 1ng/ml and 100pg/ml. Secondly, we have evaluated the separation of two herring milt hydrolysates by EDUF: the first one was more complex with a mix of different molecules (lipids, nucleic acids and peptides) while the second one was mainly composed of peptides. A new configuration using four ultrafiltration membranes (two of 50kDa and two of 20kDa) allowed a simultaneous double separation of anionic and cationic compounds. It has been shown that only charged peptides and free amino acids were fractionated in EDUF, while the lipids and nucleic acids didn’t migrate to the recovery fractions. Moreover, the use of membranes with different cut-off allowed a separation of the hydrolysates in different molecular weight ranges. Indeed, the use of 20kDa membranes allowed the concentration of peptides with small molecular weights (<800Da) and free amino acids, while the recovery fractions obtained with the 50kDa membranes were composed oh peptide with higher molecular weights.Thirdly, the potential bioactivities of the recovery fractions and the herring milthydrolysates were evaluated in vitro. Hence, the separation of the first hydrolysate allowed the production of a final fraction increasing the glucose uptake and an antioxidant anionicfraction. While the separation of the second hydrolysate allowed the production of two antiinflammatory cationic fractions as well as the identification of two bioactive peptides sequences. All these results showed that milt herring hydrolysate contained bioactive compounds such as polyunsaturated fatty acids and peptides, improving some physiological functions involved in the MetS and may decrease its occurrence. More over, the separation of the hydrolysates by EDUF allowed the production of bioactive fractions and the identification of two new anti-inflammatory peptide sequences. This work demonstrated the existence of a beneficial effect of herring milt hydrolysate and its fractions for the human health, allowing a better valorization of this by-product of the food industry for the health sector.

Full textHigh-milk protein concentrates (over 80% total protein on a dry weight basis) are typically produced by ultrafiltration (UF) with constant-volume diafiltration (DF). Polymeric spiral-wound UF membranes with a molecular weight cut-off (MWCO) of 10 kDa are mostly used at commercial scale in order to maximize protein retention. Flux decline and membrane fouling during UF have been studied extensively and the selection of an optimal UF-DF sequence is expected to have a considerable impact on both the process efficiency and the generated volumes of by-products. The objective of this work was to characterize performances of UF-DF process in terms of permeate flux decline, fouling resistance, energy and water consumption and retentate composition as a function of MWCO (10 and 50 kDa) and UF-DF sequence (3.5X – 2 diavolumes (DV) and 5X – 0.8DV). UF-DF experiments were performed on pasteurized skim milk by means of a pilot-scale filtration system operated at 50°C and under a constant transmembrane pressure (TMP) of 465 kPa. Results showed that MWCO had no impact (p>0.05) on permeate flux for a same UF-DF sequence. However, permeate flux values were significantly higher during DF for the 3.5X – 2DV sequence whatever MWCO (p<0.05). Experimental values were used as part of a simulation for the production of high milk protein concentrates in a model dairy plant processing 1500 m3 of skim milk in 20 hours. This work revealed that despite the severe total flux decline occurring during high solid concentration of milk (89% for the 5X – 0.8DV sequence vs. 58% for the 3.5X – 2DV sequence), reducing the DF step could still be of great interest in terms of energy and water consumption. The results generated by this project will benefit dairy processors producing high-milk protein concentrates with regards with their technological choices in a sustainable development perspective.

Full textPCR1 and PRC2 are complexes that control gene expression via chromatin structure reorganization. This expression regulation is maintained by adding epigentics marks H2AK119ub1 by the PRC1 and adding of H3K27me3 by the PRC2. The study devotes to study the role of the protein Pcgf1 (part of the PRC1 complex) and of the Ezh2 protein (part of the PRC2 complex) during the zebrafish development. The PRC1 complex is formed by different proteins including Pcgf proteins. There are several Pcgf homologs that have different functions. The study reveals that some Pcgf proteins have a different expression during caudal fin regeneration and development. We are interested in Pcgf1 protein during the zebrafish development. The pcgf1 gene was inactivated by using TALEN. The fish pcgf1-/- are viable and fertile. However, the early development is delayed and adults show signs of accelerated aging. This mutant is the first vertebrate model showing the role of Pcgf1 in cells proliferation during development and aging. Ezh2 protein is involved in cell-fate decisions and differenciation. Inactivation of ezh2 gene by TALEN reveals the essential role of Ezh2 during development. Indeed, at the beginning embryos develop normally then larvae die at 12 days post-fertilization. Interestingly, zebrafish embryo can gastrulate without Ezh2. This contradicts with observations in mouse model. The organs are properly formed at 5 days postfertilization. Larvae show defects in the intestinal bulb wall. Ezh2 is important for exocrine pancreas maintenance. The absence of Ezh2 causes an increase in apoptic cells. Ezh2 is essential during caudale fin regeneration

Full textIn vertebrates, primary cilia are present in virtually every cell and are involved in several signaling pathways such as the Hedgehog and Wnt pathways. Cilium dysfunctions have been causally linked to a group of pleiotropic and genetically heterogeneous human diseases, the ciliopathies. The human RPGRIP1L gene is one of the causal genes in Meckel and Joubert type B syndromes, two ciliopathies characterized by polydactyly, kidney cysts, and central nervous system malformations. The Rpgrip1l protein is enriched in the ciliary transition zone that establishes the ciliary gate controlling entry and exit of proteins in and out of the cilium. During my PhD, I studied the function of the Rpgrip1l gene in differentiation and planar cell polarity events that participate in brain morphogenesis. The first study, based on the loss of function of rpgrip1l by morpholino injection in zebrafish embryo, highlights rpgrip1l function in planar cell polarity via dishevelled stabilization, a core protein of Wnt/PCP pathway. Then, I studied the later functions of rpgrip1l and its paralogue rpgrip1 in the retina, using hypomorphic zebrafish. This work, by the discovery of rpgrip1l variants and description of photoreceptors defects, provides leads for new extra-ciliary functions of rpgrip1l in retinal morphogenesis. Ultimately, this work should result in a better understanding of the developmental origin of cerebral and retinal defects found in ciliopathies

Full textSpray drying is a well-established process but certain aspects of droplet-particle transition are not yet fully understood, resulting in variability in terms of powder quality and performance. Therefore, understanding precisely how the particle is formed and how it can be controlled still remain a major challenge. This PhD project aims to break down the complexity of the drying phenomenon using an exploratory multi-scale approach. Particle formation of milk proteins (whey proteins and casein micelles) was investigated using different experimental systems (single pendant droplet, confined droplet, mono-dispersed droplets and spraying cone droplets) in controlled drying environments (drying temperature: 20°C to 190°C and relative humidity: 40% to 2%).The results showed that the drying of a single protein droplet included three distinct stages highlighted with the occurrence of specific morphological events (constant rate shrinkage, buckling instability, vacuole nucleation). According to the type of proteins, these drying stages differed in drying kinetics and droplet dynamics, leading to characteristic and reproducible particle shapes whatever the droplet configuration and the drying conditions. These different kinds of drying behaviour were related to specific skin formation conditions and different responses of the protein material to internal stress. Finally, by means of this multi-scale approach, this work highlighted the particular signature of milk proteins in a concentrated state and in general the impact of the matter in the droplet drying process

Full textZebrafish present the ability to faithfully regenerate organs and fins after an injury by a process called epimorphic regeneration. During caudal fin regeneration, the amputation triggers the recruitment of progenitor cells towards the lesion to form a mass of undifferentiated cells, the blastema, which gives rise to the lost part of the fin. Its formation and its fate involve a coordinated regulation of cell proliferation, morphogenesis and patterning. Previous studies highlight the crucial role of signalling pathways like Fgf, Wnt, Sdfl, Shh or Bmp for the blastemal cell formation and proliferation. During this study, we show that the chemokine Sdfl a has a dual role throughout the first steps of caudal fin regeneration. First, it relays the Fgf Signalling for the formation of the blastema and then it exerts, with the Wnt pathway, a negative feedback on the Fgf pathway through the inhibition of fgfZOa expression. This negative feedback permits the regulation of the blastema size in order to regenerate a fin with the same length that the original one. Another aspect of this work was the identification of novel signalling pathways involved in blastema formation. We demonstrate that thyroid hormones signalling and apoptosis are involved in this process. The amputation triggers the expression of Deiodinase 3. This enzyme regulates locally the thyroid hormones concentration and is essential for blastema formation. The analysis of apoptotic cell death shows that this process is highly regulated in time and in space. Its inhibition by caspases activation inhibitor or its induction by retinoic acid inhibits the regeneration
