FGF18 and cancer: To determine FGF18 expression in different tumors, we investigated FGF18 expression in different paired normal and cancer tissues, namely BRCA (Figure 1A), BLCA (Figure 1B), COAD (Figure 1C), LUAD (Figure 1D), KIRC (Figure 1E), PAAD (Figure 1F), PRAD (Figure 1G), LIHC (Figure 1H), and STAD (Figure 1I), using the UALCAN database from TCGA database.
