Abstract: The present invention relates to a new biomarker for the medicine and the biology of reproduction, in particular for in vitro fertilization (IVF) outcome. It relates to methods for predicting IVF outcome and for selecting the subject for IVF.

Abstract: The invention concerns a method for selecting tumours expressing HLA-G, sensitive to an anticancer treatment, which inhibits or prevents the HLA-G activity of said tumours and the uses thereof. Said method enable to establish either the HLA-G, transcription profile of a solid tumour or the HLA-G expression profile of a solid tumour. The method for establishing the HLA-G transcription profile consists in: (i) drawing a tumoral sample; (ii) extracting the mRNA; (iii) reverse transcription (RT) of said RNA: (iv) successive or simultaneous amplification of the cDNA's obtained in (iii) in the presence of primers specific to each HLA-G isoform and analysing the resulting amplification products, by electrophoresis and/or specific hybridisation and(v) establishing said sample HLA-G transcription profile.

Abstract: The invention concerns the use of a eukaryotic cell coding for at least an HLA-G isoform, to obtain an immunomodulating medicine for inhibiting the activity of killer cells, in particular NK cells and/or for inhibiting the primary allogenic response, in parthologies or situations in which the killer cells are activated or for preparing a medicine to raise the inhibiting function of the isoform(s) expressed by said cells with respect to killer cells, in particular NK cells, in pathologies where these killer cells are inhibited by the molecule of the major histocompatibility complex of I HLA-G classes. The invention also concerns eukaryotic cells expressing at their surface at least an HLA-G isoform and their applications. The invention further concerns transgenic animals specifically expressing at least an HLA-G isoform.
