The transcription factor, nuclear factor erythroid 2 p45-related factor 2 Nrf2, acts as a sensor of oxidative or electrophilic stresses and plays a pivotal role in redox homeostasis. Oxidative or electrophilic agents cause a conformational change in the Nrf2 inhibitory protein Keap1 inducing the nuclear translocation of the transcription factor which, through its binding to the antioxidant-electrophilic response element ARE-EpRE, regulates the expression of antioxidant and detoxifying genes such as heme oxygenase 1 HO-1. Nrf2 and HO-1 are frequently upregulated in different types of tumours and correlate with tumour progression, aggressiveness, resistance to therapy, and poor prognosis. This review focuses on the Nrf2-HO-1 stress response mechanism as a promising target for anticancer treatment which is able to overcome resistance to therapies.
