The Nrf2/Keap1/ARE signaling pathway coordinates redox homeostasis and modulates anti-inflammatory and anticancer outcomes through multiple downstream routes. Nrf2 can act in opposing ways: as a tumor-suppressing cytoprotective factor under basal insult, yet when hyperactivated it supports survival of both normal and malignant cells and protects them from oxidative stress and therapy.

Oxidative stress acts to derange normal brain homeostasis, thus is involved in carcinogenesis in brain. The Nrf2/Keap1/ARE pathway isan important signaling cascade responsible for the maintenance of redox homeostasis, and regulation of antiinflammatory and anticancer activities by multiple downstream pathways. Interestingly, Nrf2 plays a somewhat, contradictory role in cancers, including brain cancer. Nrf2 has traditionally been regarded as a tumor suppressor since its cytoprotective functions are considered to be the principle cellular defense mechanism against exogenous and endogenous insults, such as xenobiotics and oxidative stress. However, hyperactivation of the Nrf2 pathway supports the survival of normal as well as malignant cells, protecting them against oxidative stress, and therapeutic agents. Plants possess a pool of secondary metabolites with potential chemotherapeutic/chemopreventive actions. Modulation of Nrf2/ARE and downstream activities in a Keap1-dependant manner, with the aid of plant-derived secondary metabolites exhibits promise in the management of brain tumors. Current article highlights the effects of Nrf2/Keap1/ARE cascade on brain tumors, and the potential role of secondary metabolites regarding the management of the same.  \nKeywords Antioxidants, ARE, Brain cancer, Keap1, Nrf2, Oxidative stress, Secondary metabolites  \n*Correspondence:  \nSaikat Dewanjee[saikat.dewanjee@jadavpuruniversity.in](saikat.dewanjee@jadavpuruniversity.in)[ ](saikat.dewanjee@jadavpuruniversity.in)Marios Papadakis [drmariospapadakis@gmail.com](drmariospapadakis@gmail.com)[ ](drmariospapadakis@gmail.com)Saurabh Kumar Jha[jhasaurabh017@gmail.com](jhasaurabh017@gmail.com)  \n1Advanced Pharmacognosy Research Laboratory, Department of Pharmaceutical Technology, Jadavpur University, Kolkata 700032, West Bengal, India  \n2Department of Pharmaceutical Sciences, College of Pharmacy and Health Sciences, St. John’s University, New York, NY 11439, USA  \n3University Centre for Research & Development, Chandigarh University, Chandigarh-Ludhiana Highway, Mohali, Punjab, India  \n4Department of Research & Development, Funogen, Athens  \n11741, Greece  \n5Department of Research & Development, AFNP Med, Wien 1030, Austria 6Department of Science and Engineering, Novel Global Community Educational Foundation, Hebersham, NSW 2770, Australia 7Department of Surgery II, University Hospital Witten-Herdecke, University of Witten-Herdecke, Heusnerstrasse 40, 42283 Wuppertal, Germany 8Department of Zoology, Kalindi College, University of Delhi,  \nDelhi 110008, India  \n© The Author(s) 2024.
