HLA-C and cutaneous melanoma: Using the “starbase” web tool (http://starbase.sysu.edu.cn/) and several available datasets including the “TCGA Skin Cutaneous Melanoma (SKCM)” dataset [70,81], the correlation between the expression of TAP1 and HLA class I loci was re-evaluated in order to determine the prognostic relevance of TAP1 (Table 1a), HLA-A (Table 1b), HLA-B (Table 1c) and HLA-C (Table 1d) expression patterns in different cancer types including skin cutaneous melanoma.
