    • PROBLEM TO BE SOLVED: To provide an easy and highly-versatile method for predicting developmental toxicity possessed by a chemical substance.SOLUTION: A method for predicting developmental toxicity possessed by a chemical substance comprises: (1) a first step of measuring an expression level of one or more genes selected from a gene including any one of specific base sequence groups or orthologue genes thereof in a specimen derived from a nonhuman mammal individual or mammalian cell having come into contact with a target chemical substance; and (2) a second step of comparing the measurement value of the expression level of the gene in the specimen obtained by the first step with the reference value of the expression level of the gene, and evaluating the level of developmental toxicity possessed by the target chemical substance in the specimen based on the compared difference. In the method for predicting the developmental toxicity possessed by the chemical substance, the gene is -mya1 gene and the expression level of the gene is measured by measuring an amount of transcription product or translation product.
    • 要解决的问题:提供一种用于预测化学物质所具有的发育毒性的简单和高度通用的方法。解决方案:用于预测化学物质具有的发育毒性的方法包括:(1)测量表达水平的第一步骤 在来源于与目标化学物质接触的非人类哺乳动物个体或哺乳动物细胞的样品中选自包括特定碱基序列组或直系同源基因中的任一种的基因的一种或多种基因; 和(2)将第一步骤获得的标本中的基因的表达水平的测定值与该基因的表达水平的基准值进行比较的第2工序,对该靶基因的发育毒性水平进行评价 基于化学物质的样本中的差异进行比较。 在用于预测化学物质所具有的发育毒性的方法中,该基因是-mya1基因,并且通过测量转录产物或翻译产物的量来测量该基因的表达水平。
