Abstract: The present invention concerns the treatment of prostate cancer and particularly castration resistant prostate cancer (CRPC). The Heat Shock Protein Hsp27, a chaperone protein, has been long demonstrated as a driver of Castration Resistance Prostate Cancer (CRPC). In the light of identification of the molecular mechanisms, the inventor determined that the Probable ATP-dependent RNA helicase DDX5 is an interactor of Hsp27 and DDX5's expression is modulated by Hsp27. They confirmed that DDX5 overexpression is correlated to the aggressiveness of the tumor, to the CRPC emergency and to the biochemical recurrence risk. They also developed DDX5-targeting antisense oligonucleotides for research purpose and clinical application. Thus, the invention relates to an inhibitor of DDX5 wherein said inhibitor reduces the expression and/or activity of DDX5 in a subject in need thereof and targets the gene or the mRNA of DDX5.

Abstract: The present invention relates to methods and pharmaceutical compositions for treating breast cancers. In particular, the present invention relates to a method for predicting the survival of a patient suffering from a breast cancer comprising i) determining the expression level of Vangl2 in a tumor sample obtained from the patient, ii) comparing the expression level determined at step i) with a predetermined reference value and iii) providing a poor prognosis when the expression level determined at step i) is higher than the predetermined reference value. The present invention also relates to a method for treating a patient suffering from a breast cancer comprising the steps consisting of i) predicting the survival of the patient according to claim 1 and ii) administering the patient with an anti-Vangl2 antibody or an inhibitor of Vangl2 expression or an inhibitor of the Vangl2-p62 interaction when it is concluded that the patient has a poor prognosis at step i).

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: 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: A method for analyzing differential gene expression associated with breast tumor is based on the analysis of the over-expression or under-expression of polynucleotide sequences in a biological sample. The analysis includes the detection of the over-expression of at least one polynucleotide sequence(s), subsequence(s) or complement(s) thereof selected from predefined polynucleotide sequence sets.

Abstract: Differential gene expression associated with histopathologic features of colorectal disease can be performed with nucleic acid arrays. Such arrays can comprise a pool of polynucleotide sequences from colon tissues, and the detection of the overexpression or underexpression of polynucleotide sequences (or subsequences or complements thereof) from this pool can provide information relating to the detection, diagnosis, stage, classification, monitoring, prediction, prevention or treatment of colorectal disease.
