    • Objective methods for detecting and diagnosing bladder cancer (BLC) are described herein. In one embodiment, the diagnostic method involves determining the expression level of a BLC-associated gene that discriminates between BLC cells and normal cells. The present invention further provides means for predicting and preventing bladder cancer metastasis using BLC-associated genes having unique altered expression patterns in bladder cancer cells with lymph-node metastasis. Finally, the present invention provides methods of screening for therapeutic agents useful in the treatment of bladder cancer, methods of treating bladder cancer and method for vaccinating a subject against bladder cancer. In particular, the present application provides novel human genes C2093, B5860Ns and C6055s whose expression is markedly elevated in bladder cancers. The genes and polypeptides encoded by the genes can be used, for example, in the diagnosis of bladder cancers, as target molecules for developing drugs against the disease, and for attenuating cell growth of bladder cancer.
    • 本文描述了用于检测和诊断膀胱癌(BLC)的客观方法。 在一个实施方案中,诊断方法包括确定区分BLC细胞和正常细胞的BLC相关基因的表达水平。 本发明进一步提供了使用在具有淋巴结转移的膀胱癌细胞中具有独特改变的表达模式的BLC相关基因来预测和预防膀胱癌转移的手段。 最后,本发明提供了筛选可用于治疗膀胱癌的治疗剂的方法,治疗膀胱癌的方法以及针对膀胱癌接种受试者的方法。 具体而言,本申请提供了在膀胱癌中表达显着升高的新型人基因C2093,B5860N和C6055。 由基因编码的基因和多肽可以用于例如膀胱癌的诊断,作为开发针对该疾病的药物的靶分子,以及用于减弱膀胱癌的细胞生长。

    • The invention features a method for inhibiting growth of a cancer cell by contacting the cell with a composition of an siRNA that inhibits expression of REG4 or KIAA0101. Methods of treating cancer are also within the invention. The invention also features products, including nucleic acid sequences and vectors as well as to compositions comprising them, useful in the provided methods. The invention also provides a method for inhibiting of tumor cell, for example pancreatic cancer cell, prostatic cancer cell, breast cancer cell, and bladder cancer cell, particularly pancreatic ductal adenocarcinoma (PDAC) by inhibiting REG4 gene. The present invention also relates to methods of treating or preventing PDAC in a subject comprising the step of administering to said subject a pharmaceutically effective amount of an antibody or fragment thereof that binds to a protein encoded by REG4. The present invention also relates to methods of diagnosing chemo-radiation therapeutic resistance of a cancer. The present invention also provides therapeutic agents or methods for treating cancer using the polypeptides. The polypeptides of the present invention are composed of an amino acid sequence which comprises polypeptide which comprises QKGIGEFF/SEQ ID NO: 21. The polypeptides of the present invention can be introduced into cancer cells by modifying the polypeptides with transfection agents such as poly-arginine.
    • 本发明的特征在于通过使细胞与抑制REG4或KIAA0101表达的siRNA的组合物接触来抑制癌细胞生长的方法。 治疗癌症的方法也在本发明之内。 本发明的特征还在于提供的方法中有用的产品,包括核酸序列和载体以及包含它们的组合物。 本发明还提供了通过抑制REG4基因抑制肿瘤细胞,例如胰腺癌细胞,前列腺癌细胞,乳腺癌细胞和膀胱癌细胞,特别是胰腺导管腺癌(PDAC)的方法。 本发明还涉及在受试者中治疗或预防PDAC的方法,其包括向所述受试者施用药学有效量的与由REG4编码的蛋白质结合的抗体或其片段的步骤。 本发明还涉及诊断癌症的化学放射治疗抗性的方法。 本发明还提供了使用所述多肽治疗癌症的治疗剂或方法。 本发明的多肽由包含包含QKGIGEFF / SEQ ID NO:21的多肽的氨基酸序列组成。可以通过用转染剂如聚精氨酸修饰多肽将本发明的多肽引入癌细胞 。
