摘要:
Plasma levels of different sub-populations of microvesicles (endothelial, leukocyte, platelet and hepatocyte) were measured by flow cytometry or ELISA/filtration on blood samples from 125 patients with cirrhosis, for which 36 of them were diagnosed with HCC at inclusion. The inventors show that the levels of microvesicles of endothelial origin (CD62E+) could predict the occurrence of HCC in patients with cirrhosis. Therefore the present invention relates to a method for determining whether a patient suffering from cirrhosis is at risk of having or developing hepatocellular carcinoma comprising determining the level of endothelial-derived microvesicles (e.g. by flow cytometry) in a blood sample obtained from the patient.

The present invention relates to tetramolecular parallel G-quadruplex-forming oligonucleotides. If G-quadruplexes are of prime importance in biology, their use is hampered by the propensity of G4-prone DNA molecules, in particular G4-prone DNA molecules of long size, to adopt many different G4 topological conformations or other alternative foldings. By introducing a lipid modification at the end of the oligonucleotide, the inventors succeeded in obtaining long tetramolecular parallel G-quadruplexes (tpG4). The present invention thus concerns an oligonucleotide modified by substitution at the 5′ or the 3′ end by a lipid moiety, wherein said oligonucleotide comprises a nucleic acid sequence of at least 10 nucleotides, said nucleic acid sequence including a series of at least 4 consecutive guanine residues located in the middle of said sequence. A tetramolecular parallel G-quadruplex comprising 4 identical modified oligonucleotides as defined above, wherein each of the 4 consecutive guanine residues included in the middle of the nucleic acid sequence of each oligonucleotide respectively form G-quartets with the corresponding guanine residues of the other 3 oligonucleotides, said G-quartets being stabilized by π-π staking and Hoogsteen hydrogen bonding, is also contemplated. The modified oligonucleotides have preferably the general formula (I) or (II), wherein the oligonucleotides are modified by substitution at the 5′ or the 3′ end by a lipid moiety, and said oligonucleotides comprise a nucleic acid sequence of at least 10 nucleotides, said nucleic acid sequence including a series of at least 4 consecutive guanine residues located in the middle of said sequence.

The present invention relates to methods and pharmaceutical compositions for preventing or reducing metastatic dissemination (i.e. reducing motility of cancer cells). In particular, the present invention relates to a method for preventing or reducing metastatic dissemination (i.e. reducing motility of cancer cells) in a subject suffering from a cancer comprising the steps consisting of i) determining the expression level of at least one biomarker selected from the group consisting of soluble CD95L and EMT promoting factors in a sample obtained from the subject, ii) comparing the expression level determined at step i) with a predetermined reference value and iii) administering the subject with a therapeutically effective amount of C16-ceramide or derivatives such as C16-sphingomyelin and C16-glycosphingolipids when the expression level determined at step i) is higher than the predetermined reference value.

The present invention relates to methods and kits for diagnosing a postoperative pulmonary infection in a patient who underwent surgery. More particularly, the present invention relates to a method for diagnosing a postoperative pulmonary infection in a patient who underwent surgery, comprising a step consisting of measuring the concentration of endocan in a blood sample obtained from said patient, at a time point comprised between 3 h and 30 h after surgery.

This method for generating an indicator of the state of a patient in coma includes: generating at least one auditory stimulation by generating a sequence of auditory stimuli, the sequence producing evoked potentials in the patient; acquiring a first electroencephalographic signal produced by patient from at least one electrode; estimating at least one pair of values corresponding to a first parameter and a second parameter extracted from the first acquired signal, including estimating a first pair of values such that calculating the first parameter includes an estimation of the amplitude variance of the first signal within a predefined time window and the calculation of the second parameter includes an estimation of the correlation of two segments of the first signal; generating a state indicator for the or each pair of values of the first and second parameters, the values defining coordinates of a point in a reference base.
