Figure 6. NF2 knockdown causes increased VSMC proliferation and migration induced by PDGF-BB via inducing YAP-TEAD1 interaction. (A) VSMC isolated from WT or Nf2-/- mice after 48 h of physiological saline or PDGF-BB (30 ng/mL) treatment was subjected to immunoprecipitation using anti-YAP antibody or control IgG. Inputs and immunocomplexes were analyzed by immunoblotting. VSMC isolated from WT and Nf2-/- mice was transfected with control siRNA, Teadi or Ad-Con, Ad-Yap and then treated by physiological saline or PDGF-BB (30 ng/mL) for 48 h. (B) VSMC treated as above mentioned was stained with SM α-actin (red), Ki-67 (green) and DAPI (blue). Representative images (left) and corresponding quantification of Ki-67-positive VSMC (right) were shown (n=5). Magnification 400×. (C) VSMC treated as above mentioned was assessed by transwell assay. Representative images (left) and corresponding quantification of migration cells (right) were shown (n=5). Magnification 100×. Data are shown as mean ± S.D. *P<0.05, **P<0.01 and ***P<0.001 denote statistical comparison between the two marked groups, respectively.
