Title: Induction of pro-viral grass carp Ctenopharyngodon idella Hsp70 instead of Hsc70 during infection of grass carp reovirus
Abstract: Grass carp Ctenopharyngodon idella Hsp70 has been identified to play a functional role in viral attachment of type III grass carp reovirus, GCRV-104. However, it remains to be clarified whether Hsc70, sharing 86% identity with Hsp70, plays a similar role during viral infection. In this study, grass carp Hsp70 was shown to be induced by GCRV-104 in different grass carp cell lines, whereas Hsc70 was expressed in a relatively constant level during the infection. The expression patterns of Hsc70 and Hsp70 were similar to their homologs in mammals. Notably, both inhibitor and over-expression assays indicated that Hsp70 was required for efficient viral replication. Thus, our study supported a novel pro-viral property of Hsp70 besides its reported role in the viral attachment. Results herein presented also suggested that the heat shock response of grass carp might be manipulated by aquareovirus to facilitate its replication in fish cells.
