MicroRNA-582-5p Contributes to the Maintenance of Neural Stem Cells Through Inhibiting Secretory Protein FAM19A1.

ABSTRACT: Epigenetic regulations on the maintenance of neural stem cells (NSCs) are complicated and far from been fully understood. Our previous findings have shown that after blocking Notch signaling in NSCs in vivo, the stemness of NSCs decreases, accompanied by the downregulated expression of miR-582-5p. In the current study, we further investigated the function and mechanism of miR-582-5p in the maintenance of NSCs in vitro and in vivo. After transfecting a mimic of miR-582-5p, the formation of neurospheres and proliferation of NSCs and intermediate progenitor cells (NS/PCs) were enhanced, and the expression of stemness markers such as Sox2, Nestin, and Pax6 also increased. The results were reversed after transfection of an inhibitor of miR-582-5p. We further generated miR-5
