Abstract: The present invention concerns a method to determine the gene expression profile on a sample previously obtained from a patient diagnosed for a liver tumor, comprising assaying the expression of a set of genes in this sample and determining the gene expression profile (signature). In a particular embodiment, said method enables to determine the grade of the liver tumor, such as hepatoblastoma (HB) or a hepatocellular carcinoma (HCC). The invention is also directed to kits comprising a plurality of pairs of primers or a plurality of probes specific for a set of genes, as well as to solid support or composition comprising a set of probes specific for a set of genes. These methods are useful to determine the grade of a liver tumor in a sample obtained from a patient, to determine the risk of developing metastasis and/or to define the therapeutic regimen to apply to a patient.

Abstract: The present invention describes that neurotrophins undergo post-translational modifications, and that these post-translational modifications mediate the pro-apoptotic and/or pro-neurite activity of neurotrophins. These post-translational modifications notably include nitration and the formation of conformationally-different dimers, as well as of abnormal oligomers, such as tetramers and octamers. The invention further relates to compounds that compete with such modified neurotrophins, as well as to compounds that bind to these modified neurotrophins. The invention thus provides useful agents for the treatment of the conditions or diseases involving chronic pain and/or neuron loss.

Abstract: The present invention relates a method to determine the presence of a photon producing biological marker in a cell, tissue or organism of interest. The method is based on Fluorescence by Unbound Excitation from Luminescence (FUEL) and comprises the steps of a) providing conditions suitable for the biological marker to produce at least one first photon by luminescence; b) providing a FUEL probe pair-upper (FPP-U) disposed in proximity to the cell, tissue or organism, wherein the at least one first photon of step a) excites the FPP-U, which emits at least one second photon. The FPP-U may be selected from the group of quantum dots, carbon nanotubes, fluorescent proteins, diamond nanocrystals and metalloporphyrins. This method is characterized in that said biological marker and said FPP-U are not bound and in that each of the at least one second photon(s) are of a longer wavelength than each of the at least one first photon(s).

Abstract: The invention relates to mutant CyaA/E570Q+K860 polypeptides suitable for use as proteinaceous vectors for delivering one or more molecules of interest into a cell, in particular into a cell expressing the CD11b receptor. The invention further relates to polypeptide derivatives suitable for eliciting an immune response in a host. The invention is more particularly directed to polypeptides derived from an adenylate cyclase protein (CyaA) either under the form of a toxin or of a toxoid, which are mutant polypeptides. Said mutant polypeptides are capable of retaining the binding activity of native CyaA to a target cell and preferably of also retaining the translocating activity of native CyaA through its N-terminal domain into target cells and furthermore have a pore-forming activity which is reduced or suppressed as compared to that of the native CyaA toxin.
