Nuclear factor-erythroid 2-related factor 2 (Nrf2) is an important factor for cells to resist oxidative stress and electrophilic attack. It is involved in the formation and control of oxidative stress defense pathways. It is associated with oxidative stress-related diseases, including cancer, neurodegenerative diseases, cardiovascular diseases and aging, and is a potential pharmacological target for the treatment of chronic diseases. This article will review the important role of Nrf2 in the regulation of cell proliferation, including direct regulation of cell proliferation, regulation of reactive oxygen species, intracellular metabolism, regulation of mitochondrial function, cell lifespan and inflammatory response. The aim is to provide a theoretical basis for further research on how to use Nrf2 to regulate cell proliferation.
