Abstract: A method of providing a prognosis or diagnosis of prostate cancer in a subject is described. The method includes obtaining a urine or prostate sample from the subject; determining the level of expression of ABCA1 in the sample; and comparing the level of expression of ABCA1 in the sample to the level of a control sample, wherein a decreased level of ABCA1 expression compared to the control indicates the subject has prostate cancer or a more severe form of prostate cancer. Methods of treating subjects identified as having prostate cancer, and kits for carrying out the method of prognosis or diagnosis are also described.
Abstract: The present invention is based on the discovery of a unique 14-gene molecular prognostic signature that is useful for predicting breast cancer metastasis. In particular, the present invention relates to methods and reagents for detecting and profiling the expression levels of these genes, and methods of using the expression level information in predicting risk of breast cancer metastasis.
Abstract: It is intended to provide an antitumor drug having an excellent therapeutic effect, which is excellent in terms of antitumor effect and safety. There is provided an antibody-drug conjugate in which an antitumor compound represented by the following formula is conjugated to an anti-TROP2 antibody via a linker having a structure represented by the following formula: -L1-L2-LP-NH—(CH2)n1-La-(CH2)n2-C(?O)— wherein the anti-TROP2 antibody is connected to the terminal of L1, and the antitumor compound is connected to the carbonyl group of the —(CH2)n2-C(?O)— moiety with the nitrogen atom of the amino group at position 1 as a connecting position.

Abstract: Recent large-scale analyses have demonstrated that the genomic landscape of human cancer is complex and variable among individuals of the same tumor type. Such underlying genetic differences may in part be responsible for the varying therapeutic responses observed in cancer patients. To examine the effect of somatic genetic changes in colorectal cancer on sensitivity to a common targeted therapy, we performed complete exome sequence and copy number analyses of 129 tumors that were KRAS wild-type and analyzed their response to anti-EGFR antibody blockade in patient-derived tumorgraft models. In addition to previously identified genes, we detected mutations in ERBB2, EGFR, FGFR1, PDGFRA, and MAP2K1 as potential mechanisms of primary resistance to this therapy. Alterations in the ectodomain of EGFR were identified in patients with acquired resistance to EGFR blockade.

Abstract: The present inventors show that cannibal cells can undergo senescence after entosis in vivo and that the tumor suppressive protein p53 act as a repressor of this phenomenon. They therefore propose new tools to study the molecular pathways involved in the cannibalism process, for example by measuring the expression levels of p53 or splice variants thereof (such as ?133TP53, TP53?, TP53? or ?40TP53), the release of extracellular ATP or purinergic P2Y2 receptor activity. The present inventors also demonstrated that the detection of senescent cannibal cells in breast adenocarcinoma obtained from patients treated with neo-adjuvant therapy positively correlates with good patient's response to treatment. Altogether, these results provide the first evidence that detection of cellular cannibalism and senescence simultaneously in tumors helps for the diagnosis of disease outcomes and for the prediction of treatment efficiency against cancer diseases.
