    • A collision construct is provided that contains a first regulatory sequence containing a first promoter linked to a reporter gene which is also linked to a second regulatory sequence containing a second promoter such that the reporter gene is under regulatory control of the first promoter. The direction of transcription under the first promoter is opposite the direction of transcription under the second promoter and activation of the second promoter interferes with reporter gene activity. The collision construct is used to screen inhibitors of the second regulatory sequence and the second promoter whereby a functional inhibitor causes an enhanced signal of the reporter gene. Vectors, host cells and kits containing the collision construct are provided, as well as methods for producing the collision construct, the vectors and host cells, and methods for screening candidate inhibitors for their ability to inhibit target promoter activities.
    • 提供了一种碰撞构建体,其包含含有与报告基因连接的第一启动子的第一调控序列,其也与含有第二启动子的第二调控序列连接,使得报道基因处于第一启动子的调控下。 第一启动子下的转录方向与第二启动子下的转录方向相反,第二启动子的活化会干扰报告基因的活性。 碰撞构建体用于筛选第二调节序列和第二启动子的抑制剂,由此功能性抑制剂引起报告基因的增强的信号。 提供载体,宿主细胞和含有碰撞构建体的试剂盒,以及用于产生碰撞构建体,载体和宿主细胞的方法以及用于筛选候选抑制剂以抑制靶启动子活性的能力的方法。

    • Gene sequences as shown in SEQ ID NO:1-18 have been discovered and isolated, and found to be significantly associated with metastatic spread of breast and colon cancer cells to other organs. Methods are provided for determining the risk of metastasis of a breast or colon tumor, which involve determining whether a tissue sample from a tumor expresses a polypeptide encoded by a gene as shown in SEQ ID NOS:1-18, or a substantial portion thereof. One of the gene sequences encodes a novel aspartyl protease termed CSP56, which can be used to provide reagents and methods for determining which tumors are likely to metastasize and for suppressing metastases of these tumors. Clinicians can use this information to predict which tumors will metastasize to other organs and to provide relevant therapies to appropriate patients.
    • 已经发现和分离了SEQ ID NO:1-18所示的基因序列,并发现与乳腺癌和结肠癌细胞向其他器官的转移性扩散显着相关。 提供了用于确定乳腺或结肠肿瘤转移风险的方法,其涉及确定来自肿瘤的组织样品是否表达由SEQ ID NO:1-18所示基因编码的多肽,或其主要部分。 其中一个基因序列编码一种称为CSP56的新型天冬氨酰蛋白,可用于提供用于确定哪些肿瘤可能转移并抑制这些肿瘤转移的试剂和方法。 临床医生可以使用这些信息来预测哪些肿瘤会转移到其他器官,并为适当的患者提供相关的治疗。
