    • The present invention is in the fields of cell biology, immunology and oncology. The invention relates to the discovery that there is a relationship between the expression levels of the tumor suppressor gene smad4 (also known as dpc4 ) and integrin α v β 6 , and the responsiveness of patient populations to α v β 6 -active compounds and compositions (e.g., antibodies and other ligands that bind α v β 6 ), particularly in cancer cells from such patient populations, more particularly on carcinomas such as pancreatic carcinomas. The invention thus provides methods for determining the responsiveness of tumor cells (particularly those from pancreatic tumors) to such α v β 6 -active compounds and compositions by examining the expression of α v β 6 and smad4 by the tumor cells, as well as methods of diagnosis and treatment/prevention of tumor progression using ligands, including antibodies and small molecule drugs, that bind to integrin α v β 6 on the surfaces of tumor cells and/or that block one or more components of the TGF-β pathway, particularly in 5/≤αrf4-deficient tumor cells.

    • The present invention is in the fields of cell biology, immunology and oncology. The invention relates to the discovery that there is a relationship between the expression levels of the tumor suppressor gene smad4 (also known as dpc4) and integrin avß6, and the responsiveness of patient populations to avß6-active compounds and compositions (e.g., antibodies and other ligands that bind avß6), particularly in cancer cells from such patient populations, more particularly on carcinomas such as pancreatic carcinomas. The invention thus provides methods for determining the responsiveness of tumor cells (particularly those from pancreatic tumors) to such avß6-active compounds and compositions by examining the expression of avß6 and smad4 by the tumor cells, as well as methods of diagnosis and treatment/prevention of tumor progression using ligands, including antibodies and small molecule drugs, that bind to integrin avß6 on the surfaces of tumor cells and/or that block one or more components of the TGF-ß pathway, particularly in 5/=arf4-deficient tumor cells.
    • 本发明涉及细胞生物学,免疫学和肿瘤学领域。 本发明涉及以下发现:肿瘤抑制基因smad4(也称为dpc4)和整联蛋白avβ6的表达水平与患者群体对avβ6活性化合物和组合物(例如,抗体和其他物质)的反应性之间存在关系 结合avß6)的配体,特别是在来自这样的患者群体的癌细胞中,更特别地涉及癌如胰腺癌。 因此,本发明提供了通过检查肿瘤细胞的avß6和smad4的表达以及诊断和治疗/预防的方法来确定肿瘤细胞(特别是来自胰腺肿瘤的细胞)对这种avβ6活性化合物和组合物的反应性的方法 使用与肿瘤细胞表面上的整联蛋白avβ6结合的配体(包括抗体和小分子药物)和/或阻断TGF-β途径的一个或多个成分,特别是在5 / arf4缺陷型肿瘤细胞中的配体 。
