A RNA interference (RNAi) mini-screening of RNA-binding proteins to identify host factors involved in dengue virus (DENV) and Zika virus (ZIKV) replications.

Huh7.5 were transduced with short-hairpin RNA (shRNA)-expressing lentiviruses at an MOI of 5–10. (A) Four days post-transduction, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays were performed to evaluate cytotoxicity effect of the knockdown (KD). Two days post-transduction cells were infected with either (B) ZIKV H/PF/2013, (C) ZIKV MR766, or (D) DENV2 16681s at an MOI of 0.01. 48 hr post-infection, the production of infectious viral particles was evaluated by plaque assays. (E) Schematic of the Renilla luciferase (Rluc)-expressing ZIKV reporter virus (ZIKV-R2A) based on the FSS13025 isolate (Asian lineage). (F) Cells were prepared, exactly as in B–D but infected with ZIKV-R2A at an MOI of 0.001. 48 hr post-infection, cells were lysed and bioluminescence was measured and normalized to the control cells expressing a non-target shRNA (shNT). Means ± SEM are shown based on three to five independent experiments for each shRNA. p<0.0001; ***: p<0.001; **: p<0.01; *p<0.05 (one-way ANOVA test).

IGF2BP2 positively regulates Zika virus (ZIKV) replication in multiple cell lines.

Liver Huh7.5 (A–C), astrocytic NHA-hTERT (D), and placental JEG-3 (E) cells were transduced with non-target shRNA (shNT) or shIGF2BP2 lentiviruses at an MOI of 10. Two days post-transduction, cells were infected with ZIKV H/PF/2013 at an MOI between 0.01 and 1 depending on the cell line. Two days post-infection, supernatant and cells were collected. IGF2BP2 expression at the protein level (A, D, E; all cell lines) and mRNA level (B; Huh7.5 cells) were evaluated by western blotting (WB) and RT-qPCR, respectively. Cell supernatants were used for plaque assays (C–E). For NHA-hTERT and JEG-3, the supernatant and cells are collected for titration and WB, respectively (E–F). 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays were performed to assess the cell viability in transduced NHA-hTERT and JEG-3 cells (D–E). Means ± SEM are shown based on five (D), three (C), and four (D–E) independent experiments. ****: p<0.0001; ***: p<0.001; **: p<0.01 (unpaired t-test).

IGF2BP2 regulates the biogenesis of Zika virus (ZIKV) replication organelles.

(A) Schematic representation of the pIRO system. Upon transfection in cells expressing the T7 RNA polymerase, this plasmid allows the cytoplasmic transcription of NS1-NS5 polyprotein under the control of T7 promoter, in a ZIKV replication-independent manner. NS1-5 polyprotein synthesis is under the control of ECMV IRES. The presence of both ZIKV 3’ NTR and 5’ cyclization sequence (5’ CS) is required for efficient vesicle packet (VP) induction. Finally, the activity of HDV ribozyme ensures that the 3’ terminus of the RNA is similar to that of viral RNA (vRNA) genome. Huh7-Lunet-T7 were transduced with short-hairpin RNA (shRNA)-expressing lentiviruses at an MOI of 5–10. Two days later, transduced cells were transfected with pIRO-Z plasmid. Sixteen hours later, cells were analyzed for (B) IGF2BP2 mRNA levels by RT-qPCR to measure knockdown efficiency, (C–D) transfection efficiency by confocal imaging of NS3-labeled cells, and (E) for VP content by transmission electron microscopy. Electron micrographs were used to measure (F) the percentage of cells with VPs and (G) the diameter of VPs in each condition. ***: p<0.001; NS: not significant (unpaired t-test).

A model for IGF2BP2 involvement in Zika virus (ZIKV) life cycle.

Step 1: After NS protein synthesis early after virus entry, IGF2BP2 associates with NS5 and vRNA, thus excluding PUM2 and TNRC6A mRNA from the ribonucleprotein (RNP). Step 2: The infection-induced association between IGF2BP2 RNP and ATL2 allows the targeting of vRNA/NS5 to the endoplasmic reticulum (ER). Step 3: Viral factors and ATL2 induce the bending of the ER membrane and the formation of vesicle packets (VPs) allowing highly processive vRNA synthesis. Step 4: IGF2BP2 might be involved in the packaging of vRNA into assembling viruses by targeting the genome to the VP pore. The recruitment of IGF2BP2 to the replication compartment might be dependent on its mTOR complex 1 (mTORC1)-dependent phosphorylation status.

Quantitative mass spectrometry-based analysis of changes in the IGF2BP2 interactome during Zika virus (ZIKV) and dengue virus (DENV) infections.

This searchable spreadsheet indicates the specific IGF2BP2 protein partners whose association is decreased or increased during ZIKV and/or DENV infection, or remained unchanged. Hits for each category are indicated with a (+). All conditions were compared to the uninfected IGF2BP2-HA condition. Protein LFQ intensity values for each biological replicate are also included in the table. This spreadsheet relates to Figure 9.
