Transgenic reporter system reveals alternative splicing expression profiles and regulatory mechanisms in mammalian organisms

摘要

An object of the present invention is to develop a new alternative splicing reporter system and to provide a method for detecting alternative splicing patterns in a mammalian multicellular organism more precisely, a method for identifying efficiently substances and gene regions that affect alternative splicing in a mammalian multicellular organism, and the like by utilizing the alternative splicing reporter system. Specifically, the present invention relates to a method for detecting alternative splicing in a mammalian multicellular organism, and a method for identifying substances and gene regions that affect alternative splicing in a mammalian multicellular organism, which use a DNA construct in which at least two different reporter genes are inserted into a specific gene that undergoes alternative splicing, or a combination of DNA constructs (a combination of at least two different DNA constructs) in which DNA construct a reporter gene is inserted into a specific gene that undergoes alternative splicing.
