Scientists demonstrated that in various cancers—including breast, head and neck, lung, colorectal, and stomach—there is a positive correlation between the expression of proinflammatory cytokines (such as IL‐1α, IL‐1β, IL‐6, IL‐8, and TNF‐α) and Fn14, the receptor for TWEAK.2, 301, 302. This evidence concerns the gene IL1B and cancer.
