Abstract
In vertebrates, neural stem/progenitor cells (NSPCs) maintenance is critical for nervous system development and homeostasis. However, the molecular mechanisms underlying the maintenance of NSPCs have not been fully elucidated. Here, we demonstrated that zebrafish ZDHHC16, a DHHC encoding protein, which was related to protein palmitoylation after translation, was expressed in the developing forebrain, and especially in the telencephalon. Loss- and gain-of-function studies showed that ZDHHC16 played a crucial role in the regualtion of NSPCs proliferation during zebrafish telencephalic development, via a mechanism dependent on its palmitoyltransferase activity. Further analyses showed that the inhibition of ZDHHC16 led to inactivation of the FGF/ERK signaling pathway during telencephalic NSPCs proliferation and maintenance. Taken together, our results suggest that ZDHHC16 activity is essential for early NSPCs proliferation where it acts to activate the FGF/ERK network, allowing for the initiation of proliferation -regulated gene expression programs.
