HMOX1 and ovarian cancer: In xenograft models, NRF2 overexpression promoted tumor growth and increased the expression of antioxidant and angiogenic factors, including heme oxygenase-1 and vascular endothelial growth factor A. Collectively, these findings demonstrate that NRF2 regulates ovarian cancer aggressiveness and chemoresistance by coordinating stress response signaling, survival pathways, and tumor progression.
