From: The deubiquitinase USP22 regulates PD-L1 degradation in human cancer cells
USP22 is a potential partner and regulator of PD-L1. a Interaction network of PD-L1 analyzed in BioGrid database. b H1792, H1299 cells were transfected with control (CTRL) or USP4, USP7, USP22 siRNA for 24 h and then subjected to western blot analysis. c Western blot analysis of USP22 and PD-L1 expression in seven NSCLC cell lines. Relative intensity of USP22 and PD-L1 were normalized to ACTB. The pearson correlation coefficient for the protein expression were presented
