Fig. 2: PD-L1 is positively correlated with p-MerTK protein levels in human NSCLC tissues.

a Western blot assay of PD-L1 and p-MerTK protein levels in 24 paired NSCLC tissues and the corresponding adjacent tissues. b Relative quantification of PD-L1 and p-MerTK protein levels in 24 paired NSCLC tissues. The Y axis refers to the log10-transformed fold change of the T/N expression ratio. The X axis represents sample number. c The correlation between PD-L1 and p-MerTK protein levels in 24 paired NSCLC tissues. d IHC assay of PD-L1 and p-MerTK protein expression in NSCLC tissues (Scale bar: 100 μm, 50 μm).
