Abstract: A method for predicting the sensitivity of tumor cells to an anthracycline-based chemotherapy includes determining the differential expression level of a MYBL2 gene in tumors cells. A polynucleotide library is useful to predict the sensitivity of tumor cells to an anthracycline-based chemotherapy and includes a pool of polynucleotide sequences or subsequences thereof wherein the sequences or subsequences correspond substantially to any of the polynucleotide sequences SEQ ID No: 308, SEQ ID No: 309 and/or SEQ ID No: 310 or the complements thereof.

Abstract: A method for diagnosing a myeloid cancer in a subject, includes the step of analyzing a biological sample from the subject by determining the presence or the absence of a mutation in the ASXL1 (additional sex combs like 1) gene coding for the polypeptide having the sequence SEQ ID N°2. A kit for diagnosing myeloid cancer in a subject including at least one nucleic acid probe or oligonucleotide or at least one antibody, which can be used in a such a method is also described.

Abstract: Methods for identifying ERBB2 (also named HER2) alteration in tumors, in particular cancer, based on the analysis of the expression of at least three genes of the ERBB2 amplicon located within less than one megabase on either side of ERBB2, and eventually of the gene corresponding to the Affymetrix probeset 234046_at (SEQ ID NO: 31), as well as a poynucleotide library useful for the molecular characterization of a cancer including polynucleotide sequences for detecting the genes, and a kit including the library.

Abstract: Method for molecular characterization of a carcinoma including: (i) detecting in tumor cells corresponding to breast tumor cells at least one polynucleotide selected from a first group determining expression level of the polynucleotide from the first group to differentiate a tumor in which a lymph node has been invaded by a tumor cell from a tumor in which a lymph node has not been invaded by a tumor cell; (ii) detecting in tumor cells corresponding to breast tumor cells at least one polynucleotide selected from a second group determining expression level of the polynucleotide from the second group to distinguish tumors sensitive to anthracycline from tumors insensitive to anthracycline; (iii) detecting in tumor cells corresponding to breast tumor cells at least one polynucleotide selected from a third group determining expression levels of the polynucleotide from the third group to classify good and poor prognosis primary breast tumors.

Abstract: The present invention relates to a method for analyzing cancer. e.g., breast cancer including detection of differential expression of at least one of the 16 genes encoding serine/threonine kinases listed in Table 1, or of the 16 genes, and to a polynucleotide library including at least one the 16 genes. This finds use in the development of novel applications, in particular in the development of prognosis or diagnostic of breast cancer or for monitoring the treatment of a patient with a breast cancer.

Abstract: The present invention relates to a method of assessing a propensity of clinical outcome for a female mammal suffering from breast cancer in view of the expression of specific nucleic acid sequences in a biological sample.

Abstract: The present invention concerns the V617F variant of the protein-tyrosine kinase JAK2, said variant being responsible for Vaquez Polyglobulia. The invention also relates to a first intention diagnostic method for erythrocytosis and thrombocytosis allowing their association with myeloproliferative disorders, or to the detection of the JAK2 V617F variant in myeloproliferative disorders allowing their reclassification in a new nosological group.

Abstract: A process for analyzing a complex biological state of a biosystem from a sample of nucleic acids isolated from the biosystem including hybridization of the nucleic acids with probes fixed on a support, including: (a) contacting marked polynucleotide sequences prepared from nucleic acids of the sample with a first set of specific polynucleotide probes (E1) of a biological state and at least a second set of reference polynucleotide probes (E2) prepared from a molecule of reference nucleic acid for the biological state under conditions permitting the formation of hybridization products, and (b) detecting the hybridization products formed in step (a), wherein the first and second sets (E1, E2) are fixed on a support and the first set of probes includes n groups of probes, each group being characteristic of a different genetic profile that influences the biological state and can therefore alter it, and each group being assembled on the support in separate positions that are also separated from that (those) of the

Abstract: A method for analyzing differential protein expression associated with histopathologic features of breast disease including detecting overexpression or underexpression of a pool of proteins in breast tissues or cells, the pool including at lease one of a protein set including Afadin, Aurora A, a-Catenin, b-Catenin, BCL2, Cyclin D1, Cyclin E, Cytokeratin 5/6, Cytokeratin 8/18, E-Cadherin, EGFR, ERBB2, ERBB3, ERBB4, Estrogen receptor, FGFR1, FHIT, GATA3, Ki67, Mucin 1, P53, P-Cadherin, Progesterone receptor, TACC1, TACC2, TACC3, Cytokeratin 6, Cytokeratin 18, Ang1, AuroraB, BCRP1, CathepsinD, CD10, CD44, CK14, Cox2, FGF2, GATA4, Hif1a, MMP9, MTA1, NM23, NRG1a, NRG1beta, P27, Parkin, PLAU, S100, SCRIBBLE, Smooth Muscle Actin, THBS1 and TIMP1.
