Figure Lengend Snippet: (A) PK-15 cells were transfected with siESCRTs or siCtrl and then inoculated with CSFV (MOI = 10), and the cells were harvested for RT-qPCR at 1 hpi. These data are presented as the mean + SD of data from three independent experiments. *, P< 0.05; **, P <0.01. (B) PK-15 cells were transfected with siESCRTs or siCtrl and then inoculated with CSFV (MOI = 0.1), then harvested the whole cell cultures at 24 hpi for RT-qPCR. These data are presented as the mean + SD of data from three independent experiments. *, P< 0.05; **, P <0.01. (C) PK-15 cells were transfected with siESCRTs or siCtrl and then inoculated with CSFV (MOI = 0.1), at 24 hpi, the cell supernatant were harvested and used for infected new PK-15 cells, and harvested the new cells at 24 hpi for RT-qPCR. These data are presented as the mean + SD of data from three independent experiments. *, P< 0.05; **, P <0.01. (D) PK-15 cells were treated as described in panel B. At 24 hpi, the cells were harvested and subjected to Western blotting by using the indicated antibodies as follows: rabbit anti-ESCRTs antibody, rabbit anti-Npro antibody, or mouse anti-β-actin antibody. These data are representative of three independent experiments. (E and F) PK-15 cells were transfected YFP-tagged ESCRT-III or vector plasmid and then inoculated with CSFV (MOI = 0.1). At 24 hpi, the cell culture was harvested, respectively, for RT-qPCR and Western blotting described above. These data are presented as the mean + SD of data from three independent experiments. *, P< 0.05; **, P <0.01. (G) PK-15 cells were infected with CSFV (MOI = 1) for indicated time points, then cells were harvested and subjected to Western blotting by using the indicated antibodies against ALIX, HRS, VPS25, CHMP1A, CHMP2B, CHMP4A, CHMP4B, CHMP7, VPS4A, Npro and β-actin. These data are representative of three independent experiments. (H) PK-15 cells were transfected doses of indicated plasmids (pFlag-NS3, -NS4B, -NS5A, -NS5B, -Core, -E2) or vector for 48 hpt, then harvested and subjected to Western blotting by using rabbit anti-ESCRTs antibody or mouse anti-Flag antibody, along with β-actin as a loading control. These data are representative of three independent experiments.
Article Snippet: The lysates were then treated with mouse anti-Flag antibody (Invitrogen, USA) or mouse anti-HRS/VPS28/VPS25/VPS4A antibody (Santa-cruz, USA), rabbit anti-CHMP2B/CHMP4B/ALIX antibody (Cell-signaling-technology, USA), rabbit anti-CHMP7 antibody (Proteintech, USA), then incubated with rotation for 4–6 h at 4°C.
