Outline of Final Research Achievements

Musashi1 (Msi1) is a RNA-binding, which is highly expressed in neural stem/progenitor cells and is responsible for stem cell maintenance and differentiation. The main function of Msi1 is to regulate the expression of its target mRNAs through translational up/down-regulation.
In search for novel Msi1 targets, in vitro SELEX selection was performed from a mouse embryonic brain mRNA library, and a 3’ UTR fragment of dcc was obtained. Dcc is a transmembrane receptor expressed on the growth cones of neurons, and it guides axons and cells in response to Netrin1.
In this project, in vitro and in cultured cell experiments clearly identified that the dcc mRNA is a direct target of Msi1, and is suppressed their translation through a canonical molecular machinery. Now, we are analyzing the connection between the molecular mechanism and neural development by using Msi1-KO mice.
