Figure 5. The analysis of biological effects of key gene -IL18. (A) IL18 expression in different cancers and paired normal tissue in the TIMER2 database. (B) IL18 gene mutation types in different cancer species. (C) Subcellular localization of IL18 gene in different cancer cell lines. (D) The expression information of IL18 at single cell level was analyzed in model animal mouse single cell database. (E, F) DNA methylation database showed that methylation levels at different sites of IL18 were correlated with survival and prognosis.
