Figure Legend Snippet: Inhibition of MNK1 phosphorylation in GGNNV-infected GB cells reduces p-MNK1 and p-eIF4E production as well as coat protein translation. A GB cells were infected with GGNNV (MOI = 100). Cells were fixed at 0, 12 and 24 hpi and immunostained for p-MNK1 (green) and coat protein (red). B The cytotoxic effect of MNK1 phosphorylation inhibitor, CGP57380 on GB cells was evaluated by MTT assay. GB cells cultured in a 96-well plate were treated with different concentrations of CGP57380 for 24 h. The cell viabilities were detected with a MTT kit. Values are presented as mean ± SD ( n = 3).

Figure Legend Snippet: Schematic illustration of how NNV hijacks host machinery for virus protein synthesis and particle assembly. After several rounds of RNA replication/transcription near the mitochondria outer membrane, NNV RNAs are transported from mitochondrial spherules (site of replication) to translation factories. These factories are fused together and later concentrated in perinuclear area at a reorganized MTOC. The resulting viral factories (VFs) are architecturally supported by cytoskeleton proteins. Nuclear movement and reshaping may occur due to LINC complexes connecting nucleus to cytoskeletal elements. The VFs and remodeled MTOC act as a microenvironment to divert host proteins like p-p38, p-ERK, p-MNK1, p-eIF4E, p-eIF4E-BP, RPS6 and other translation factors important for NNV coat protein translation. Outside the VFs and remodeled MTOC, NNV downregulates p-p70S6k/p-RPS6 pathway which phosphorylates RPS6 crucial for host translation. Moreover, NNV inhibits host translation by inducing translocalization and sequestration of PABP in nucleus. These events are followed by degradation of PABP via the 26 S proteasome system .
