ATCC human embryo kidney hek293t cells

(A) WT, SPCS1 KO <t>HEK293T,</t> SPCS1 KO cells transfected with empty vector or FLAG-tagged SPCS1 were infected with RRV at an MOI of 3, and cells were collected for western blot analysis at 12 hpi using anti-FLAG and SPCS1 antibodies to confirm the protein level of SPCS1. (B) The lysates and supernatants were collected for FFU assays to determine the titers. (C) WT and SPCS1 KO HEK293T cells were infected with RRV, SA11 and UK strains at an MOI of 3. At 12 hpi, all the cell lysates and supernatants were collected for FFU assay to detect the titers. (D) WT and SPCS1 KO Huh7.5 cells were infected with RRV, SA11 and UK strains at an MOI of 3, respectively. At 12 hpi, all the cell lysates and supernatants were collected for FFU assay to detect the titers. (E) WT and SPCS1 KO HEK293T cells were transfected with siRNAs targeted against SPCS2 , SEC11A , SEC11C and a scrambled siRNA at the concentration of 20 nM. At 48 hpi, cells were infected with RRV at an MOI of 3. The cell lysates and supernatants were collected for FFU assay to detect the titers at 12 hpi. The results are the averages of data in three independent experiments and plotted as mean ± SD. Statistical significance was determined using two-way ANOVA with Sidak’s multiple comparisons test (**, P < 0.01; ***, P < 0.001, **** P < 0.0001).

(A) WT and SPCS1 KO HEK293T cells were infected with RRV at an MOI of 3. At 4, 8, 12 hpi, the cells were collected for qRT-PCR analysis of viral mRNA level by detecting NSP5. The NSP5 level was normalized to that of GAPDH. Results are the average of data in triplicates and plotted as mean ± SD. (B) WT and SPCS1 KO HEK293T cells were infected with RRV at an MOI of 3. At 4, 8, 12 hpi, the infected cells and mock cells were harvested for western blot analysis of viral protein level by detecting VP6 protein. (C) WT and SPCS1 KO HEK293T cells were infected with RRV at an MOI of 3. At 12 hpi, an immunofluorescence assay was performed to detect the viroplasms in the infected cells. Cells were fixed and probed with in-house polyclonal antibody against NSP5; the positive cells were shown as green fluorescence. Nuclei were counterstained with DAPI. Representative data from one of three independent experiments are shown. Scale bar, 50 μm.
