Additional file 3 of Sulforaphane enhances the antitumor response of chimeric antigen receptor T cells by regulating PD-1/PD-L1 pathway

Additional file 3: Figure S1. The quantitative analysis of Western blot data. A Relative expression of PD-1 protein level in control and SFN group. The quantitative analysis of PD-1, p-AKT, p-mTOR, p-S6, t-AKT, t-mTOR, t-S6 protein level in control group, SFN group, and PI3K/AKT inhibitor group. B Relative expression of PD-L1 protein level of control, IFN- γ and IFN- γ + SFN group in A549 and H322. C The quantitative analysis of β-TrCP protein level of control, IFN- γ and IFN- γ + SFN group in A549 and H322. D The quantitative analysis of β-TrCP protein level of siRNA transfection efficacy in A549 and H322 cells. E Relative expression of PD-L1 protein level was detected in the presence of IFN- γ or SFN after si-Scr or si-BTRC by western blot in A549 and H322 cells
