The expression levels of CCR5 in the various malignancies. A Upregulated or downregulated CCR5 in human various malignancies from TCGA database were determined by TIMER 2.0 (*p < 0.05, **p < 0.01, ***p < 0.001). B-G For the type of DLBC, GBM, LGG, SKCM, TGCT, and THYM in the TCGA project, the corresponding normal tissues of the GTEx database were included as controls. The box plot data were supplied (*p < 0.05, **p < 0.01, ***p < 0.001). (H). Upregulated CCR5 expression in HNSC tissue specimens compared with the normal tissue specimens from TCGA database. I The mRNA level of CCR5 in pairs of HNSC tissue specimens and their paired normal adjacent tissue specimens. J The correlation analysis between CCR5 and PD1 (PDCD1) mRNA level. K The receiver-operating characteristic (ROC) curve analysis of CCR5 in HNSC patients
