Abstract

The disclosed forming device comprises a die (12) having an impact face (24) and an associated magnetic means (30) able to generate a transverse magnetic field outgoing relative to the orientation of the impact face. When the device exerts a pushing or repulsive force in a determined direction (A) on a sheet (2) or the like made of electrically conductive material, one portion (2a) of this sheet is deformed or bent in a die-receiving region by being projected at high speed toward the impact face. The magnetic means, which is placed on the side of the die (12) and generates the magnetic field, forms an eddy current braking system for decreasing the speed of the portion (2a) as the latter approaches the impact face (24) and enters into the zone of action of the magnetic field, thus improving the precision of the forming process.

Abstract

The present invention relates the treatment and prognostic of cancer like glioblastoma. Here, the inventors focused their study on the impact of presence of N6-adenosine methylation in miRNA-200b-3p in samples of patients suffering from glioblastoma multiforme (GBM). Their study was particularly focused on the impact of miRNA-200b-3p and its adenosine methylation on the expression of XIAP. XIAP acts as an anti-apoptotic protein via the inhibition of caspase-3 and -7 activation and high XIAP expression is associated with a poor survival in several solid tumors. Thus, the miR-200b-3p-mediated repression of XIAP mRNA expression appears as a mechanism governing the caspase-3 and -7 activity and the apoptosis. In theory, in the presence of miR-200b-3p, XIAP mRNA expression is repressed and caspase-3 and -7 can be activated to promote apoptosis. Thus, the present invention relates to an in vitro method for determining the prognosis of the survival time of a patient suffering from a cancer comprising the steps consisting of i) determining the expression level of the miR-200b-3p and/or the N6-adenosine methylated miRNA-200b-3p (miR-200b-3p m6A) in a sample from said patient and to the N6-adenosine methylated miRNA-200b-3p (miR-200b-3p m6A) for use in the treatment of a cancer in a subject in need thereof.
