Abstract:
The present invention relates to CD31 shed agonists for use in the prevention and/or treatment of reperfusion injury. These CD31 shed agonists are peptides or peptidomimetics thereof that are able to restore CD31 signaling in cells bearing a truncated form of CD31 called CD31 shed . The CD31 shed agonists according to the invention particularly protect from organ damages caused by reperfusion used to treat ischemia.
Abstract:
This invention relates to the field of small size pH-responsive tools, especially for measuring a pH value in biological media. I-motif DNA structures have been extensively used in the art for the fabrication of nanodevices; however, it is still a challenge to assist the folding of multi-stranded i-motif, especially at physiological pH. The inventors have conceived a multi- stranded i-motif-based pH-responsive tool, which comprises a poly-nucleic acid complex, instead of the mono-nucleic acid complexes which were known in the art. The poly-nucleic acid complex according to the invention is far easier to design, and may be easily adapted depending on the pH- range of interest to be measured. The poly-nucleic complexes of the invention are useful for designing a variety of pH-responsive devices, and especially pH biosensors and pH-sensitive delivery systems, particularly in the pharmaceutical field.
Abstract:
The present invention relates to a novel use of total cellular iron, preferably under the form of ferrous iron (Fe 2+ ), as a marker of cancer stem cells (CSCs). The invention also relates to methods using said iron marker, in particular for metastatic cancer diagnosis or treatment, for screening for compounds of interest, as well as for killing CSCs.

Abstract:
The present invention relates to a method for determining responsiveness to vandetanib in a patient suffering from medullary thyroid carcinoma (MTC). The prediction of a therapeutic response to vandetanib, used in the treatment of MTC, is of great interest. By following studies on 62 MTC tissues taken from patients, the inventors showed that the over-expression of miRNA-375 and/or the down-regulation of the SEC23A gene is (are) associated with a decrease in the cancer cells proliferation and with an increase in the response to vandetanib. The present invention thus relates to a method for determining responsiveness to vandetanib in a patient suffering from MTC comprising a step of detecting the level of expression of the miRNA-375 (e.g. by RT-PCR) and/or precursors thereof and/or of the SEC23A gene (e.g. by immunoblotting and immunohistochemistry) in MTC cells of said patient. The invention also concerns an inhibitor of the SEC23A gene expression for use in the treatment of MTC, in combination with vandetanib.
Abstract:
The present invention relates to the use of a homeoprotein or a recombinant vector encoding said protein for treating or preventing DNA damage and/or cellular aging. In particular, the invention concerns the use of Engrailed for the treatment of Parkinson disease.
Abstract:
The present invention relates to gelling compositions, which changes from liquid state to gel state in function of temperature comprising: at least a poloxamer or mixture of poloxamers; at least a gelling agent; and at least an anticancer agent. Said compositions are advantageously used for local administration of an anticancer agent. Said compositions are useful for size-reduction of a tumour before surgical removal of said tumour, for preventing tumour recurrence after surgical removal of a tumour, and/or treating small tumours. They are therefore useful for the treatment of cancer, preferably a cancer of a wall of the digestive system or a gynaecologic cancer. The present invention also relates to a method for preparing said gelling compositions.
Abstract:
La présente invention concerne l'utilisation de l'Hydroxycarbamide (HC) pour atténuer et/ou retarder l'extension de la non-perfusion capillaire, cause de baisse visuelle irrémédiable chez les patients souffrant d'occlusion de veine centrale de la rétine (OVCR). Il s'agit ici du premier traitement systémique permettant de réduire les complications ischémiques rétiniennes chez des patients dont l'OVCR a été diagnostiquée récemment et est par conséquent dans une phase de progression rapide. Compte tenu de la faible toxicité de l'HC évaluée à grande échelle chez l'enfant et l'adulte dans le cadre d'autres maladies depuis des décennies, les résultats de la présente étude ouvrent une nouvelle voie thérapeutique dans le traitement de l'OVCR.
Abstract:
La présente invention a pour objet un procédé de greffe d'au moins une cellule cardiaque ou d'au moins d'une cellule capable de se différentier en une cellule cardiaque sur la membrane chorioallantoïde vascularisée d'un œuf fécondé. La présente invention a également pour objet un procédé de caractérisation de l'activité d'un composé vis-à-vis du tissu cardiaque mettant en œuvre un œuf fécondé sur la membrane chorioallantoïde duquel a été greffé au moins une cellule cardiaque ou au moins d'une cellule capable de se différentier en une cellule cardiaque. La présente invention a également pour objet un kit comprenant un œuf fécondé sur lequel a été greffé au moins une cellule cardiaque ou au moins une cellule capable de se différentier en une cellule cardiaque.
