  • Publication number: 20130011845
    Abstract: The present invention relates to a miRNA regulating the insulin signaling pathway, and to a method for screening a material for controlling the action of a target gene thereof, and particularly, to a method for screening a material for controlling the action of USH or FOG2, a target gene of miR-8 or miR-200 miRNA for promoting cell growth. The present inventors discovered miR-8, a conserved miRNA for regulating the body of a fruit fly by targeting u-shaped material (USH) in the fat cells of Drosophila. It was also confirmed that a target gene of miR-200, a human homologous gene of Drosophila miR-8 miRNA, is FOG2. It was found that Drosophila miR-8 and USH are also conserved in mammals, and FOG2, a human homologous gene of USH, directly binds to a regulating subunit of PI3K and functions. It was confirmed that when the expression of miR-200 is inhibited or FOG2 is expressed in a human cancer cell line, the activity of PI3K, which promotes cell growth, is decreased.
