Bioinformatic analysis of GSE71729 dataset also evidenced that MRP4 is upregulated in 17 established pancreatic cancer cell lines compared to tumor and peritumor samples (p < 0.001), suggesting that elevated expression of MRP4 is associated with the process of carcinogenesis and may confer an adaptive phenotype to cells growing in culture. The gene discussed is ABCC4; the disease is neoplasm.
