| 摘要 |
The present invention provides a transgenic non-human mammal which has DNA encoding a foreign reporter protein for monitoring changes in intracellular calcium ion concentration and expresses the reporter protein in one or more types of non-neuronal cells; a method for producing the above transgenic non-human mammal; a method for detecting changes in intracellular calcium ion concentration using the above transgenic non-human mammal; DNA having promoter activity which is used for production of the transgenic non-human mammal; and the method of use of the DNA. The non-human mammal of the present invention expresses the DNA in one or more tissues or organs selected from the group consisting of epithelial tissue, connective tissue, adipose tissue, cartilage tissue, bone tissue, muscle tissue, intraoral tissue, blood tissue, bone marrow, cardiovascular organ, lymphatic organ, teeth, digestive tractl, liver, gallbladder, pancreas, respiratory organ, urinary organ, genital organ, endocrine organ, sense organ and nail, and can be used for evaluation of pharmacological effect and activity of physiologically active substances (for example, drug), novel gene products having unknown functions and the like in these tissues or organs. |
