Fig. 3. WIP is a downstream molecule of PD-L1.
a PD-L1 was knocked down by siRNA in H460 and H358 cells. (b) Overlap of changed genes affected by PD-L1 siRNA silencing in H460 and H358 lung cancer cells. c Heatmap showing the subset of 12 genes identified in H460 and H358 NSCLC cells followed by PD-L1 silencing. d The regulation of gene expression by PD-L1 was analyzed by RT-PCR assay in H460 and H358 cells. e KEGG analysis showed that genes were enriched in the actin cytoskeleton pathway. f, g The expression of WIP was detected by RT-PCR and western blot.
