    <p>To identify cofactors of IGF2BPs, we ectopically expressed FLAG-IGF2BP2 in HEK293T cells, pulled down the IGF2BP2 complexes using FLAG antibody and conducted mass spectrometry analysis. Immunoprecipitaion with IgG control and the subsequent mass spectrometry analysis were perform in parallel as a negative control. Proteins identified with 4 or more unique peptides each at 99% confidence are listed in the "Processed data.xlsx" file.</p><p></p

    <p>(A) After transfection of vtRNA1-1, RBD or vtRNA1-1/RBD, sensitivity to DOX was measured in MCF-7 cells. (B) the expressing levels of GAGE6 and PSF after the DOX treatment were detected in MCF-7 transfected with vtRNA1-1, RBD or vtRNA1-1/RBD and the relative folds were qualified (C). (D) ChIP was performed to detect the binding of PSF to GAGE6 promoter in MCF-7 transfected with vtRNA1-1, RBD or vtRNA1-1/RBD after DOX exposure. CCK-8 assay (E) or PI staining (F) was performed to detect cell viability in MCF-7 transfected with vtRNA1-1 after DOX exposure. *P<0.05.</p

    <p>MDCK cells were infected at an MOI of 0.001 in the presence of 1 µg/ml TPCK-trypsin. After adsorption for 1 h at 37°C, the inocula were removed and the cultures were washed 3 times. The cells were incubated at 37°C for 6 h. At the indicated time, the cells were processed for immunofluorescence, and the infected cells were detected with polyclonal antisera to whole viruses. (A) Fluorescence images of the infected cells at 6 h p.i. Fluorescent photomicrographs showing the intracellular expression of virus protein in cell culture. The FITC-fluorescence signal was expressed as the infected cells. (B) Volocity Demo software analysis of the ratios of infected cells according to the Fig. 5A. *, statistical significance (<i>p</i><0.05) (C) Flow-cytometric analysis of virus-infected cells at 6 h p.i. MDCK cells (2×10<sup>6</sup>) in suspension were incubated with PBS or anti-PR8 antibodies on ice. Then the FITC-conjugated IgG secondary antibodies were added. After washing, the cells were fixed and the number of infected cells was determined by flow cytometric analysis. *, statistical significance (<i>p</i><0.05).</p
