Fig. 7

A Activation of NK1R by hHK-1 transactivated phosphorylation of EGFR (pY1068). Cells were treated by 1 μM hHK-1 in indicated time after starving 2 h. B Aprepitant inhibited the phosphorylation of EGFR stimulated by 1 μM hHK-1 or by 0.1 μg EGF treatment. Total EGFR protein was used as loading control. C Aprepitant inhibited ERK1/2 and AKT phosphorylation induced by EGF. Total ERK and Akt protein were used as loading control. D Total or phosphorylated EGFR and NK1R expression in cells transfected with lenti-CRISPR sgRNA target to EGFR by western blot. E Cell proliferation in EGFR knockout cells with or without hHK-1/EGF treatment for 72 h (Celltiter-Glo assay). F Transwell assay for cell migration in EGFR konckout cells with or without hHK-1/EGF treatment. Data were shown as mean ± SD from three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001.
