To further study the relationship between PD-L1 and ezrin/radixin in human colorectal tissue, we finally examined whether the gene expression of PD-L1 was correlated with that of ezrin and radixin in colon adenocarcinoma samples from The Cancer Genome Atlas (TGCA) database [48] using UALCAN, a comprehensive and an interactive web resource for in-depth analysis of cancer OMICS data [49]. Here, EZR is linked to cancer.
