We assessed 122 immunomodulators, including MHC, receptors, chemokines, and immune stimulators, as reported by Charoentong et al.40 and found that most of these immunomodulators were significantly negatively related to TBX3 expression in several cancers, particularly in BLCA (Figure S2A). This evidence concerns the gene HLA-C and bladder transitional cell carcinoma.
