Abstract

C1q-like is a significant maternal factor of TNF/C1q super-family, and the abundant protein has been observed in both mature eggs of Carassius auratus and Carassius auratus gibelio, but its biological function in early embryo development has remained unclear. In this study, we firstly revealed a high level of maternal C1q-like transcript existence only in mature eggs of Carassius auratus, whereas no any maternal C1q-like transcript was observed in that of Carassius auratus gibelio. During embryonic development, the C1q-like zygotic expression begins around cardiopalmus stage in embryos of both Carassius auratus and Carassius auratus gibelio. Then, we examined the biological role of C1q-like by morpholino-mediated knockdown in early embryo development. Knockdown of CaOC1q resulted in a significant reduction of primordial germ cells (PGCs) in Carassius auratus, as shown by whole mount in situ hybridization with vasa-specific RNA probe, fluorescence immunostaining of vasa protein, and GFP imaging of the GFP-nanos1-3'UTR mRNA reporter. In vitro and in vivo evidence indicated that a microRNA, miR-430 could repress the C1q-like expression and PGC development. These data suggest that C1q-like should be a direct target of miR-430 and play an essential role in PGC development of Carassius auratus.
