This invention relates to methods, agents and compositions for regulating the neoantigen landscape of cancer cells, based on the realisation that intron retention in a cancer cell can be manipulated. Agents that can modify retained intron neoantigen expression in cancer cells are described, and their use in drug discovery and therapy. One aspect provides an agent for use in a method of treating cancer by modifying the neoantigen profile of at least one cancer cell. The agent may typically be a protein arginine N-methyltransferase 5 (PRMT5) inhibitor, and/or may reduce methylation of an E2F protein, for example E2F1.

The present invention is intended to provide a method for determining the prognosis of a hormone receptor-positive cancer (for example, an ERα-positive breast cancer, an ERα-positive endometrial cancer, etc.) or a method for assisting the determination of the prognosis, and a method for evaluating the sensitivity of the cancer to antihormone therapy or a method for assisting the evaluation of the sensitivity of the cancer to antihormone therapy. Specifically, the present invention relates to a method for determining the prognosis of a hormone receptor-positive cancer, or a method for assisting the determination of the prognosis, which comprises the following steps (a) and (b): (a) a step of detecting Fbxo22-positive cancer cells in a sample derived from the cancer tissues; and (b) a step of calculating the percentage of the Fbxo22-positive cancer cells to the cells present in the sample.

Disclosed is a method for selecting a potential subject with benefiting from a pharmaceutical composition for treating or preventing cancer, comprising: determining the presence or absence of a mutation in tumor protein p53 (TP53) gene and/or BCL6 co-repressor (BCOR) gene by using a sample collected from the subject; and providing an indication that the subject is a potential subject with benefiting from the pharmaceutical composition in the case of TP53 wild type and/or BCOR wild type.

Methods and products for the identification and detection of new endometrial cancer biomarkers based on proteins in plasma and/or uterine lavage extracellular vesicles.

Methods for preparing ex vivo T cell cultures using IL-21 compositions for use in adoptive immunotherapy are described. Addition of IL-21 to cultures of non-terminally differentiated T cells population, either isolated or present in peripheral blood mononuclear cells are exposed to one or more tumor antigens, and in the presence of IL-21 compositions and antigen presenting cells (APCs), the resulting T cell population has an enhanced antigen-specificity, and can be reintroduced into the patient. Methods are also disclosed for identifying tumor antigens by culturing T cell populations exposed to IL-21 compositions and APCs in the presence of tumor material.

The present disclosure relates to methods for detecting brain tumors and assessing the recurrence of such tumors by administering a pharmaceutical composition comprising 5-aminolevulinic acid (5-ALA) and detecting the conversion of 5-ALA to protoporphyrin IX (PPIX) associated with brain-derived microparticles.

A magnetic separation device has a membrane having a plurality of pores, a magnetically soft material layer disposed on the membrane, and a passivation layer disposed on the magnetically soft material layer. The magnetic separation device may be part of a microfluidic device having a lateral flow channel and a vertical flow magnetic separation filter. The magnetic separation device may be used to separate magnetically tagged particles, such as cells.

Chemical entities that are kinase inhibitors, pharmaceutical compositions and methods of treatment of cancer are described.

A method is used for treating bone metastasis diseases in subjects. The method preferably depends on whether the subject shows certain specific proteins levels in one or more body fluids prior to or during treatment. The treatment includes the administration of at least one pan αv integrin inhibitor to a subject, a medicament for use in said new methods, and a method of predicting the outcome of a treatment with at least one pan αv integrin inhibitor based on the specific protein levels in one or more body fluids of the subject.

The invention relates to obtaining, isolating and detecting a new marker of epithelial cancers. A method comprises obtaining biological samples from patients with suspected malignant neoplasms of the epithelium and from a control group of healthy subjects. Next, a new marker of epithelial cancers that forms on the surface of cancer cells of epithelial origin is isolated. If the level of expression of the epithelial cancer marker in the samples obtained from the patients exceeds the level of expression of the marker in the samples obtained from healthy subjects, then the result indicates a high probability that epithelial cancer is present. The cancer antigen is a family of N-glycoproteins that have identical N-glycosylation and have a molecular mass of 55-85 kD. The detection method includes a capture reagent for the indicated cancer antigen, a detection reagent and a detection reagent.
