Figure Lengend Snippet: KIF20A regulates PD-L1 expression via c-Myc (A and B) Huh7 and HCCLM3 cells were transfected with KIF20A small interfering RNAs (siRNAs) or KIF20A overexpression (OE) pcDNA3.1 plasmids, respectively. The protein levels of KIF20A, c-Myc, and PD-L1 were measured by WB in Huh7 and HCCLM3 cells. (C) ChIP-PCR was performed to assess the binding of c-Myc to the PD-L1 promoter region in Huh7 cells. (D) Huh7 cells were transfected with c-Myc siRNAs, and the knockdown efficiency of c-Myc was verified by RT-PCR. (E and F) Huh7 and HCCLM3 cells were co-transfected with KIF20A OE plasmids and c-Myc siRNAs. The protein levels of KIF20A, PD-L1, and c-Myc were determined by WB. (G) Huh7 cells were co-transfected with pGL3-PD-L1 or pGL3-basic plasmids, KIF20A OE pcDNA3.1 plasmids, c-Myc siRNAs, and pRL-TK plasmids, followed by luciferase activity assay. (H and I) KIF20A promotes HCC cell immune evasion by regulating PD-L1 expression via c-Myc. HCC cells from different groups were co-cultured with CD8 + T cells. Representative FC plots and quantitative analysis of GzMB and IFN-γ expression in CD8 + T cells co-cultured with Huh7 cells. (J and K) Representative images and quantitative analysis of colony formation in Huh7 cells with or without CD8 + T cell co-culture. Data are presented as mean ± SD. Statistical analyses were performed using Student’s t test (D), one-way ANOVA (C, I), or two-way ANOVA (G, K). ∗∗ p < 0.01 and ∗∗∗ p < 0.001. All experiments were repeated three times.
