However the molecular networks regulating the stemness and differentiation of NSCs have not been fully understood. In this study, we show that Tweety-homolog 1 (Ttyh1), a five-pass transmembrane protein specifically expressed in mouse brain, is involved in maintaining stemness of murine NSCs. Blocking or activating Notch signal led to downregulation and upregulation of Ttyh1 in cultured NSCs, respectively, suggesting that Ttyh1 is under the control of Notch signaling. Knockdown of Ttyh1 in cultured NSCs resulted in a transient increase in the number and size of neurospheres, followed by a decrease of stemness as manifested by compromised neurosphere formation, downregulated stem cell markers, and increased neuronal differentiation. We generated Ttyh1 knockout mice by deleting its exon 4 using the CRISPR-Cas9 technology. Surprisingly, in contrast to a previous report, Ttyh1 knockout did not result in embryonic lethality. NSCs derived from Ttyh1 knockout mice phenocopied NSCs transfected with Ttyh1 siRNA. Immunofluorescence showed that loss of Ttyh1 leads to the increase of neurogenesis in adult mice. Taken together, these findings indicate that Ttyh1, which is likely downstream to Notch signaling, plays an important role in regulating NSCs."xsd:string |
