BACKGROUND The Chinese sturgeon (Acipenser sinensis) is endangered through anthropogenic activities including over-fishing, damming, shipping, and pollution. Controlled reproduction has been adopted and successfully conducted for conservation. However, little information is available on the reproductive regulation of the species. In this study, we conducted(More)
C1q family proteins with C1q domain have been reported in vertebrates, but their biological roles are currently unknown. In this study, a C1q-like factor, designated Carassius auratus gibelio ovary-specific C1q-like factor (CagOC1q-like), was identified as a cortical granules component. Immunofluorescence localization revealed that the C1q family member was(More)
Dead end (dnd) encodes an RNA-binding protein that is essential for primordial germ cell (PGC) migration and gametogenesis in vertebrates. In this study, a Chinese sturgeon Acipenser sinensis dead end homologue, designated Asdnd, was identified and characterized. The full-length cDNA of Asdnd was 1630base pairs (bp) and encoded a peptide of 396 amino acid(More)
The Chinese sturgeon, Acipenser sinensis, is a rare and large-sized anadromous bony fish and understanding of its reproductive regulation is a precondition for controlled reproduction. In this study, two gonadotropin-releasing hormone (GnRH) precursor cDNAs, AsGnRH1 (mammalian type) and AsGnRH2 (chicken type 2), were sequenced in A. sinensis. The precursor(More)
