Fig. 4. Nogo-B regulates NPC cell migration through NgR3.
A Lysates from HEK293T cells transfected with NgR3-myc and Nogo-B-flag were subjected to immunoprecipitation using beads with anti-flag antibody, and coimmunoprecipitated NgR3-myc was detected by Western blotting. The total protein expression levels were confirmed. B Lysates from HEK293T cells transfected with NgR3-myc and Nogo-B-flag were subjected to immunoprecipitation using beads with anti-myc antibody, and coimmunoprecipitated Nogo-B-flag was detected by Western blotting. The total protein expression levels were confirmed. C CNE2 cells were transfected with NgR3-myc and Nogo-B-flag. Immunofluorescence showed that NgR3 and Nogo-B were colocalized. D NgR3 siRNA or Nogo-B siRNA could not influence each other’s protein expression. E The average number of invaded CNE2 cells in three fields decreased by NgR3 siRNA even when Nogo-B was overexpressed.
