Natural Dietary Compounds Targeting NF‐κB Signaling in Cancer: Implications for Nutrition‐Based Prevention and Therapy

open access: yesFood Frontiers, Volume 7, Issue 1, January 2026.
ABSTRACT Dysregulation of the nuclear factor kappa B (NF‐κB) signaling pathway is closely associated with inflammation‐driven carcinogenesis, tumor progression and resistance to conventional therapies. Sustained NF‐κB activation enhances malignant cell survival, proliferation and immune evasion by promoting proinflammatory and antiapoptotic gene ...
