    • PROBLEM TO BE SOLVED: To provide a method for predicting the carcinogenicity of a tested material. SOLUTION: The method for predicting the carcinogenicity of the tested material includes the following first to third steps at the prediction of the carcinogenicity of the tested material, after previously preparing expression patterns by administering a carcinogen (C+M+) positive to the Ames test and a carcinogen (C+M-) negative to the Ames test to test animals, and collecting mRNAs from the test animals after a prescribed time passes: the first step for subjecting the test material to the Ames test and determining whether the test material belongs to the positive or negative in the Ames test; the second step for obtaining the expression pattern by collecting the mRNA from a test animal to which the tested material is administered; and the third step for predicting the carcinogenicity of the tested material by calculating the identity frequency with the expression pattern of the mRNA of the carcinogen positive to the Ames test when the tested material is positive to the Ames test at the first step, and with the expression pattern of the mRNA of the carcinogen negative to the Ames test when the tested material is negative to the Ames test at the first step.

    • 要解决的问题:提供一种预测被测材料的致癌性的方法。

      解决方案:预测测试材料的致癌性的方法包括以下第一至第三步骤,在预测测试材料的致癌性之前,先前通过将致癌物(C + M +)施用于 Ames测试和对Ames测试阴性的致癌物(C + M-)进行测试,并在规定的时间过后从测试动物收集mRNA:第一步,将测试材料进行Ames测试,并确定测试 材料属于Ames测试中的正或负值; 通过从施用被测试材料的测试动物中收集mRNA获得表达模式的第二步骤; 以及第三步,通过在第一步对Ames测试测试材料为阳性时,通过计算与Ames测试阳性的致癌物质mRNA表达模式的身份频率来预测测试材料的致癌性,并与 当测试材料在第一步对Ames测试为阴性时,对Ames测试阴性的致癌物的mRNA的表达模式。 版权所有(C)2008,JPO&INPIT
