摘要： c-Myc is a transcription factor and master regulator of cellular metabolism, and plays a critical role in virus replication by regulating glutamine metabolism. In this study, the open-reading frame (ORF) of c-Myc, designated as Sc-c-Myc, was cloned and sequenced. Multiple alignment of the amino acid sequence showed that the conserved domain of Sc-c-Myc, including the helix-loop-helix-zipper (bHLHzip) domain and Myc N-terminal region, shared high identities with other homologues from different species. Sc-c-Myc mRNA was widely expressed in the examined tissues of mandarin fish, and the higher mRNA levels was expressed in hind kidney. Moreover, mRNA and protein level of Sc-c-Myc was significantly increased in the Chinese perch brain (CPB) cells and spleen of mandarin fish post infection with infectious spleen and kidney necrosis virus (ISKNV) and Siniperca chuatsi rhabdovirus (SCRV). Sc-c-Myc overexpression promoted ISKNV and SCRV replication, on the contrary, knocking down Sc-c-Myc restrained ISKNV and SCRV replication. These results indicated that Sc-c-Myc involved in ISKNV and SCRV replication and proliferation, providing a potential target for the development of new therapic strategy against ISKNV and SCRV.
