Figure Lengend Snippet: ( a ) Characteristics of the average tandem 3′ UTR length during the anti-VSV immune response. Human and mouse showed similar patterns. ( b ) The number of poly(A) site-switched genes at consecutive time points in human MDMs upon VSV infection. ( c ) Poly(A) site switching at consecutive time points in human MDMs upon VSV infection. The x axis denotes TSI, and a larger positive value indicates that longer tandem 3′ UTRs were observed at later time points. Genes with significant switching to longer (blue) or shorter (red) tandem 3′ UTRs at later time points (FDR=0.01) are coloured accordingly. The y axis denotes the logarithm of the expression level of genes from later time points relative to earlier samples. ( d ) Venn diagram showing the overlap of DEGs and poly(A) site-switched genes.

Article Snippet: MDMs and mouse peritoneal macrophages were infected with VSV (strain Indiana, ATCC) at 0.5 MOI in serum-free DMEM for 1 h, washed by 1 × PBS, and incubated with fresh complete medium for various periods of time (0, 2, 4, 8, 16 and 24 h).

Figure Lengend Snippet: ( a ) siRNAs were transfected into A549 cells, and the interference efficiency was determined with qRT-PCR at 48 h. ( b ) We transfected A549 cells with individual siRNAs for 48 h and infected them with VSV-eGFP at an MOI of 1 for 6 h or 12 h. Then, qRT-PCR was performed to detect VSV replication at the mRNA level. Data are mean±s.d. * P <0.05; ** P <0.01. ( c ) FACS analysis of A549 cells transfected with control siRNA (siCon) or the indicated siRNAs and then infected with VSV-eGFP at an MOI of 2 for 6 h. FACS gating strategies from one representative experiment have been provided as . ( d ) A549 cells were transfected with individual siRNAs for 48 h and infected with VSV at an MOI of 1 for 12 h. Then, western blotting was performed to detect VSV replication at the protein level. The uncropped scans of western blots have been provided as . ( e ) Relative mRNA expression of the core 3′ processing factors in VSV-infected MDMs. Data were obtained from two biological duplicates of IVT-SAPAS. The x axis denotes six time points post infection and the y axis denotes relative expression. ( f ) Relative 3′ UTR length of the core 3′ processing genes with switched poly(A) sites during the antiviral immune response. Data were obtained from IVT-SAPAS. The x axis denotes six infection time points and the y axis denotes e UTR/c UTR, which represents the ratio of longer 3′ UTR isoforms to total mRNA isoforms.
