Abstract
As a novel IGF system member, igf3 plays an important role in gonadal development of teleost fish. Although studies have reported the unusual expression of igf3 in fish gonad, whether the igf3 affects the expression of long noncoding RNAs (lncRNAs) in gonad remains unknown. In this study, an igf3 knockdown common carp (Cyprinus carpio) model was established by RNA interference. Then RNA sequencing of C. carpio gonad after igf3 knockdown was performed. A total of 327,169,410 and 306,305,018 clean reads were identified from control and igf3-dsRNA interference group, respectively. After a stringent filtering, RNA-seq yielded 14199 lncRNA and 106932 mRNA transcripts with 124 and 353 differentially expressed lncRNAs and mRNAs. Our dataset provides an extensive resource for understanding the potential regulatory molecular mechanism of igf3 in early stage of gonadal development in C. carpio.
