Narrative review reveals oxidative stress and electron transfer groups drive carcinogenesis across cancer models, suggesting unifying mechanisms for prevention.

Key Points

To synthesize evidence on how oxidative stress and electron transfer functionalities drive chemical carcinogenesis and unify disparate cancer mechanisms.
Literature review analyzing diverse mechanisms of carcinogen action, redox cycling, and cellular transformation.
Evaluation of reactive oxygen species generation, oncogene activation, DNA binding, and the protective roles of antioxidants across endogenous and exogenous exposures.
Carcinogens and their metabolites frequently contain electron transfer moieties—including quinones, metal complexes, aromatic nitro compounds, and conjugated imines—that generate reactive oxygen species via redox cycling.
Oxidative stress provides a unifying mechanistic framework linking DNA mutations, oncogene activation, aging, and diet to cancer initiation and progression.
The electron transfer–oxidative stress framework generalizes beyond carcinogenesis to explain the bioactivity of multiple drug classes, environmental toxins, enzymes, and hormones.
