wherein R, R.sub.0, R.sub.1-R.sub.8, n, X, Y, Y, and E are as described herein, pharmaceutical compositions containing such compounds, and methods of treating or preventing a disease or condition for example, cancer, mediated by the ras gene.

A polynucleotide, which is a novel causative gene for cancer, is elucidated, and, based on this finding, provided are a method for detecting the polynucleotide, or a polypeptide encoded by the polynucleotide; a kit and a primer set for the detection; a method for screening an inhibitor of the polypeptide; and a pharmaceutical composition for treating a cancer containing the inhibitor. In the detection method of the present invention, an NTRK3 fusion protein, or a fusion gene encoding the fusion protein, or an ETV6 fusion protein, or a fusion gene encoding the fusion protein, in a sample derived from the digestive system obtained from a subject, is detected.

The purpose of the present invention is to provide a method for predicting the effectiveness of an angiogenesis inhibitor in a subject suffering from a tumor. Provided is a method comprising a step of testing for the presence or absence of an a mutation or loss of expression of B-Raf and PTEN in a sample of tumor tissue from the subject. By using the presence or absence of or a mutation or loss of expression of B-Raf and PTEN as an indicator, this method enables the antitumor effectiveness of the angiogenesis inhibitor to be predicted without administering the angiogenesis inhibitor to the subject.

The present invention relates to compositions and methods for the in vitro diagnosis of prostate cancer, wherein said compositions comprise an antibody binding to progastrin and said methods comprise the use of an antibody binding to progastrin.

The present invention relates to compositions and methods for-determining a treatment course of action. In particular, the present invention relates to compositions and methods for the prediction of a subject's response to cancer therapies and administration of appropriate treatments.

The invention provides to RAF1 gene fusions, RAF1 fusion proteins, and fragments of those genes and polypeptides. The invention further provides methods of diagnosing and treating diseases or disorders associated with RAF1 fusions, such as conditions mediated by aberrant RAF1 expression or activity, or overexpression of RAF1.

Provided is a means for detecting and quantifying a biological substance of interest with an improved accuracy by inhibiting non-specific adsorption of fluorescent nanoparticles and thereby reducing the background noise in immunostaining with fluorescent nanoparticles. Immunostaining is carried out upon diluting fluorescent nanoparticles with a fluorescent nanoparticle diluent which contains 1 to 5% (W/W) of a protein having a molecular weight of 40,000 or higher (e.g., BSA) and 1 to 3% (W/W) of a protein having a molecular weight of less than 40,000 (e.g., casein) and, when casein is used as a low-molecular-weight protein, it is preferred that the -casein content in the casein is 10% (W/W) or less and the ratio of -casein and -casein (-casein:-casein) contained in the casein is 40:60 to 60:40 (taking the total amount of -casein and -casein as 100).

One aspect of the present disclosure relates to an isolated mutant human estrogen receptor alpha (hER) that may be used in methods of drug discovery. The isolated mutant hER can include a DNA-binding domain (DBD), a ligand-binding domain (LBD), and an interface between the DBD and the LBD, wherein at least one tryptophan residue is mutated to a phenylalanine residue.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

Methods of reducing chemotherapy-induced metastasis, or chemotherapy-induced cancer cell dissemination, for patients subject to chemotherapy using Tie-2 inhibitors. Methods of reducing chemotherapy-induced metastasis, or chemotherapy-induced cancer cell dissemination, for patients subject to chemotherapy using inhibitors of Mena expression and/or function are also provided.
