GP1BA and neoplasm: We carried out a stromal/immune analysis comparing metastases of SKCM stratified according to their GP1BA expression (high/low by median), which showed that the expression of this gene is linked to a more stromal (p = 9.70 × 10−7) and inflammatory/immune-infiltrated (p = 2.25 × 10−24) tumor microenvironment (Figure S2A).
