LCN2 and neoplasm: Data from the TCGA and GTEx database showed that LCN2 mRNA expression was significantly higher in ACC, BLCA, CESC, CHOL, COAD, ESCA, KIRP, LIHC, LUAD, PAAD, READ, STAD, THCA, UCEC, and UCS tumor tissues compared to that in normal tissues, indicating that it might function as an oncogenic molecule in the development of diverse tumors (Figure 1A).
