ABCC1 and neoplasm: 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.
