    • Compositions for the diagnosis and therapy of prostate and colon cancer, derived from or based on a novel prostate-specific, androgen-regulated, cell membrane associated and secreted serine protease termed 20P1F12/TMPRSS2 are described. A full length cDNA comprising the entire coding sequence of the 20P1F12/TMPRSS2 gene (also designated 20P1F12-GTC1 herein) is provided (FIG. 1). Among the compositions provided are antibodies that bind to 20P1F12/TMPRSS2 proteins and polypeptide fragments thereof, including antibodies labeled with a detectable marker or toxin or therapeutic composition. The invention also provides prognostic and diagnostic methods of examining a biological sample for evidence of disregulated cellular growth by comparing the status of 20P1F12/TMPRSS2 in the biological sample to the status of 20P1F12/TMPRSS2 in a corresponding normal sample, wherein alterations in the status of 20P1F12/TMPRSS2 in the biological sample are associated with disregulated cellular growth. The invention further provides various therapeutic compositions and strategies for treating prostate cancer, including particularly, 20P1F12/TMPRSS2 polypeptide and anti-20P1F12/TMPRSS2 antibody therapy methods and compositions, cancer vaccines, and small molecule therapy.
    • 描述了衍生自或基于称为20P1F12 / TMPRSS2的新型前列腺特异性,雄激素调节的细胞膜相关和分泌的丝氨酸蛋白酶的前列腺和结肠癌的诊断和治疗的组合物。 提供了包含20P1F12 / TMPRSS2基因(本文中也称为20P1F12-GTC1)的整个编码序列的全长cDNA(图1)。 所提供的组合物是结合20P1F12 / TMPRSS2蛋白和其多肽片段的抗体,包括用可检测标记或毒素或治疗组合物标记的抗体。 本发明还提供了通过将生物样品中20P1F12 / TMPRSS2的状态与对应的正常样品中的20P1F12 / TMPRSS2的状态进行比较来检查生物样品以检测细胞生长失调的证据的预后和诊断方法,其中, 生物样品中的20P1F12 / TMPRSS2与细胞生长失调有关。 本发明还提供了治疗前列腺癌的各种治疗组合物和策略,特别包括20P1F12 / TMPRSS2多肽和抗-20P1F12 / TMPRSS2抗体治疗方法和组合物,癌症疫苗和小分子治疗。
