A query of human tumor transcriptomic data for 471 melanoma patients from The Cancer Genome Atlas (TCGA) dataset revealed a positive correlation of IGF1 and ABCC9, ABCG1, ABCB1, and ABCC4 with GHR expression, and ABCC1 with both GHR and IGF1R expression (Figure 3E), supporting our observations. Here, IGF1 is linked to melanoma.
