Full textRNA splicing involves the processing of pre-messenger RNA molecules by the excision of introns and the precise joining of exons to form the mature messenger RNA that is exported from the nucleus for translation. Exon usage is often alternative, i. E. The cell decides whether to remove a part of the pre-mRNA as an intron or include this part in the mature mRNA as an alternative exon. Alternative splicing is therefore, a genetically economical process that enables a single gene to increase its coding capacity, allowing the synthesis of several structurally and functionally distinct protein isoforms. To avoid accumulation of aberrantly spliced mRNAs, several quality control processes determine the fate of mRNA in the cell. Among these processes, Nonsense-Mediated mRNA decay (NMD), is able to degrade mRNA containing premature termination codons (PTCs), preventing accumulation of truncated with deleterious effects for the cell. As central mechanisms controlling gene expression any disturbance of either splicing or NMD can lead to genetic diseases. Indeed, the numbers of diseases shown to be caused by a defect in pre-mRNA splicing or NMD is rapidly growing. For example, in ataxia telengectasia or type I neurofibromatosis, 54% of disease-inducing mutations affect mRNA splicing. Moreover, one third of acquired and inherited pathologies are due to nonsense creation that elicits NMD. Consequently, mRNA splicing and NMD represent a potential targets for new therapeutic strategies. During this thesis, we have screened a small chemical library to find splicing and NMD inhibitors. We have identified some molecules that modulate mRNA splicing efficiency by affecting SR proteins activity. We have also isolated the first specific inhibitor of NMD that blocks hUpf1 functions. These compounds allowed us to decipher splicing and NMD mechanisms and to propose a new model to describe the NMD-subjected mRNP transit trough the processing-Bodies. The next challenge will be to demonstrate the functional utility of these molecules in preclinical models of human disease

Full textTransition metal elements have d valence electrons and are characterized by a great variety of electronic configurations responsible for their specific reactivity. The elements of the second row in particular have 4d and 5s atomic orbitals of similar size and energy which can be both involved in chemical processes. We have been interested in the reactivity of a transition metal element, zirconium, combined with a simple organic functionalized molecule in a van der Waals complex formed in a supersonic molecular beam in the model reaction Zr + CH3F. In this context, one of the chemicals reactions that we are interested in leads to the formation of ZrF. The electronic spectroscopy of ZrF in the spectral domain 400 – 470 nm is extremely rich and surprising for a diatomic molecule. With this study, we have been able to identify the ground state of ZrF (X2) by simulating the observed rotational structures and obtain essential information on the electronic structure. These experimental results are in agreement with ab initio calculations. The excited states of the complex Zr. . . F-CH3 have been studied with a depopulation method. The spectral domain 615 – 700 nm is particularly interesting because it reveals a group of diffuse bands red-shifted and broadened with respect to the transition z3F←a3F in the metal. This transition is forbidden from the ground state a3F2 of zirconium but allowed from the a3F4 state. Complexation of the metal atom with a CH3F molecule allows coupling of these two states to occur which ensures the optical transition from the ground state of the complex

Full textAfter we found a new electrochemical way to synthesize thin films of polyethylenimine and polypropylenimine at electrode surfaces, we have realized a detailed electrochemical study of these reactions and we have characterized polymers obtained by electrochemical oxidation using various spectroscopies and microscopies (SEM, AFM, Raman, IR, XPS). Then we have determinated electropolymerization mechanisms using ab initio calculations. And finally, we have developed applications of these electrosynthesized polymers in the field of chemical sensors (pH sensors) and biochemical sensors (for the urea detection)
