However, the mechanism by which they are quantitatively controlled is unknown. We show that the amount of mature miR-9, a key regulator of neuronal development, increases during zebrafish neurogenesis in a sharp stepwise manner. We characterize the spatiotemporal profile of seven distinct microRNA primary transcripts (pri-mir)-9s that produce the same mature miR-9 and show that they are sequentially expressed during hindbrain neurogenesis. Expression of late-onset pri-mir-9-1 is added on to, rather than replacing, the expression of early onset pri-mir-9-4 and -9-5 in single cells. CRISPR/Cas9 mutation of the late-onset pri-mir-9-1 prevents the developmental increase of mature miR-9, reduces late neuronal differentiation and fails to downregulate Her6 at late stages. Mathematical modelling shows that an adaptive network containing Her6 is insensitive to linear increases in miR-9 but responds to stepwise increases of miR-9. We suggest that a sharp stepwise increase of mature miR-9 is created by sequential and additive temporal activation of distinct loci. This may be a strategy to overcome adaptation and facilitate a transition of Her6 to a new dynamic regime or steady state.","lang":"eng"}],"type":"journal_article","file":[{"content_type":"application/pdf","file_name":"2022_Development_Soto.pdf","access_level":"open_access","creator":"dernst","relation":"main_file","checksum":"d7c29b74e9e4032308228cc704a30e88","file_id":"12438","success":1,"file_size":9348839,"date_created":"2023-01-30T08:35:44Z","date_updated":"2023-01-30T08:35:44Z"}],"day":"01","article_processing_charge":"No","month":"10","pmid":1,"date_updated":"2023-08-04T09:41:08Z","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"quality_controlled":"1","title":"Sequential and additive expression of miR-9 precursors control timing of neurogenesis","status":"public","related_material":{"link":[{"relation":"software","url":" https://github.com/burtonjosh/StepwiseMir9"}]},"oa_version":"Published Version","oa":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_created":"2023-01-16T09:53:17Z","publisher":"The Company of Biologists","scopus_import":"1"}
