Full textCes proteines de 9 kda sont secretees par les racines et les feuilles de cet hybride mais ne sont jamais detectees chez le genotype non-embryogene. Cet extrait proteique est constitue de ltps basiques secretees uniquement au cours de la phase d'expression mais egalement de ltps acides presentes des la phase d'induction, l'identite de ces proteines ayant ete confirmee par microsequencage. Enfin, les tissus foliaires induits a l'embryogenese sont caracterises par une elevation du rapport stigmasterol/sitosterol. Les effets du miconazole, inhibiteur de la c-14 demethylase, enzyme impliquee dans la biosynthese des sterols, ont ete observes au cours de la culture des fragments foliaires. Ce fongicide induit un blocage des divisions embryogenes et de la formation des embryons et provoque des modifications du profil proteique tissulaire. Ces differents elements constitueraient donc de bons candidats au titre de marqueurs de l'embryogenese somatique, nous permettant de progresser dans la comprehension de ce phenomene

Full textExcessive consumption of fat has emerged as a major cause of increased prevalence of metabolic diseases. After their hydrolysis in the intestinal lumen, fatty acid (FA) and monoglycerides are absorbed by the enterocytes. Inside these cells FA are bound to small cytosolic proteins, the FABPs, before to be re-esterified into triglycerides then secreted as lipoproteins into the chyle. Enterocytes express I-FABP and L-FABP whose specific role in intracellular FA trafficking is still unknown. To clarify this point we have carried out an in vivo structure-function study by immunocytochemical characterization of transfected Cos-1 cells expressing large amounts of proteins. These proteins target a fluorescent FA to cellular sites of metabolism (mitochondria and endoplasmic reticulum / Golgi apparatus). When each protein is expressed within the cell, the fluorescent bound-FA is specifically distributed, suggesting a specific function. Conversely, when both proteins are present they cooperate for the distribution of the FA in similar areas than those targeted by the I-FABP expressed alone suggesting a sensor role for this protein. Another approach has been to show that the regulation of the expression of I-FABP and L-FABP differed in the rat model of metabolic syndrome induced by a fructose-enriched diet. To enlarge our knowledge of this model, the effects of polyunsaturated omega-3 FA intake on the expression of genes involved in energetic homeostasis and infammatory pathways were described. A specific role of PPAR delta in the liver and the heart was evidenced

Full textThe biointegration of bone implant involves a cascade of processes initiated by the adsorp-tion of surrounding molecules to the biomaterial surface. This step to end up at biofilm formation playing a central role in cell adhesion and bone regeneration upon contact with implant. Based on this observation, the surface modification research on biomaterial properties has been develo-ped to control and promote biomaterial-protein-cell interactions. To promote these interfacial processes, we propose to develop a novel titanium surface combining the grafting of a "bioac-tive" polymer, polystyrene sulfonate (polyNaSS) and the use of platelet rich plasma (PRP). The aims of this work are, firstly, to study the adsorption capacity of bioactivated titanium (titanium-polyNaSS) towards PRP proteins and secondly, to evaluate in vitro titanePolyNaSS/PRP model on the behavior of human mesenchymal stern cells (hMSCs). About biomaterial-PRP interactions, the results allowed to demonstrate an increase of the pro-tein adsorption capacity of titanium-polyNaSS and a selectivity of this adsorption, compa-red to ungrafted titanium. About cellular responses induced by the biomaterial, titanium-polyNaSS improves hMSCs spreading and stimulates osteoblast differentiation. Moreover, the use of PRP as nutritional supplement increases cell proliferation speed compared to fetal calf serum (FCS) cultures, enhances the titanium-polyNaSS effects on osteoblast differentiation. This work confirms the interest of titane-polyNaSS/PRP model for the development of new bio-logically active orthopedic prostheses promoting osteointegration

Full textUrothelial carcinoma is the most common solid malignancy ot the b\adder. Tumors can be classified into three categories: (i) tumors confined to the urothelium (pTa) which will recur at least once and progress to infiltrating or less differentiated neoplasms; (ii) muscle-invasive carcinomas (>pT2) and (iii) tumors confined to the lamina propria (pTl) that will progress to a poor prognosis muscle-invasive disease and are potentially lethal. The clinical outcome of stroma-invasive (pTl) bladder tumors is unpredictable, that is why novel prognostic factors, that would give information independently of classical predictors, are necessary to improve the biological assessment of the PTI tumors. Vascular Endothelial Growth Factor (VEGF or VEGF-A) is considered as one of the most important angiogenic regulator in tumor angiogenesis. Northern-blotting analysis and quantitative RT-PCR revealed that VEGF transcript levels were higher in PTI and pT2 bladder cancers than in pTa tumors, which suggested that VEGF mRNA level could serve as a prognostic indicator of progression in bladder cancer. In a previous study, we reported that in two different human bladder cancer cell lines, RT4 (derived from grade I papillary carcinoma) and T24 (derived from grade Ill undifferentiated carcinoma), VEGF was differentially up-regulated by the three PPAR isotypes. Its expression was increased by PPARa, p, and in RT4 cells and only by PPARß in T24 cells. We hypothesized that the loss of nuclear localization of a protein related to the FABP family in grade Ill undifferentiated carcinomaderived T24 cells could explain this difference because some isotypes of FABP could regulate the PPAR transcriptional activity through transport of P PAR agonists from cytoplasm to nucleus. We demonstrated that A-FABP is present in the cytoplasm and in the nucleus of RT4 cells and strictly in the cytoplasm ofT24 cells. We reported, from clinical samples of bladder tumors, that the decrease of A-FABP transcript level is significantly linked to tumor stage and to histologic grade. A loss of A-FABP expression is observed in poor prognosis high grade PTI tumors in comparaison to good prognosis tumors suggesting that A-FABP is a tumor suppressor gene. Thus, the re-expression of AFABP could be a putative therapeutic approach in early stage bladder cancer to prevent disease progression. We demonstrated that this marker is up-regulated by pharmacological molecules such as fibrates and thiazolidinediones (PPARa and y agonist). According to these results, these molecules could be used for bladder cancer treatment

Full textAfter an accidental overexposure, the assessment of the received dose in biological dosimetry is performed by a method based on the effects of irradiation on the DNA molecule. But this technique shows some limitations; therefore we tried to find new biosensors of radiation exposure. We have pointed out that membrane is a critical target of ionising radiation after an in vitro and in vivo overexposure. In vitro, these modifications were involved in the radio-induced apoptotic pathway. The measure of membrane fluidity allowed us to obtain an overall view of cellular membrane. Moreover, in vivo, by changing the lipid nutritional status of animals, our results displayed the important role played by membrane lipid composition in radio-induced membrane alterations. Besides, membrane effects were adjusted by the extracellular physiological control and in particular by the damages on membrane fatty acid pattern. Finally, we have tested the use of membrane fluidity index as a biosensor of radiation exposure on in vivo models and blood samples from medical total body irradiated patients. The results achieved on animal models suggested that the membrane fluidity index was a biosensor of radiation exposure. Nevertheless, the observations realised on patients highlight that the effect of the first dose fraction of the radiotherapy treatment had some difficulties to be noticed. Indeed, the combined treatment: chemotherapy and radiotherapy disturbed the membrane fluidity index measures. To conclude, whereas this parameter was not a biosensor of irradiation exposure usable in biological dosimetry, it may allow us to assess the radio-induced damages and their cellular but also tissue impacts
