Programmed death-ligand 1 (PD-L1) and PD-L2 expression in endometrial cancer (EC). (A) The expression of PD-L1 and PD-L2 in EC patients. The mRNA expression (log2) of PD-L1 and PD-L2 in 506 EC samples, divided by 397 for type I and 109 for type II, from the TCGA database. ***p < 0.0001 PD-L2 vs PD-L1. (B) PD-L1 and PD-L2 protein expression was evaluated by Western blot in normal human uterus and six EC cell lines. PD-L1 and PD-L2 densitometry values were normalized to glyceraldehyde-3-phosphate dehydrogenase (GAPDH) used as loading control. Densitometric values shown are the mean ± SE of three separate experiments. *p < 0.05 vs normal control, #p < 0.05 vs type I primary EC cell line PCEM002.
