Summary

In this keynote lecture, Masayuki Yamamoto presents the KEAP1-NRF2 pathway as a central sensor and effector of cellular stress responses. He traces the historical discovery of the pathway, from the identification of phase II detoxification enzymes and the antioxidant response element to the cloning of NRF2 and its partner sMaf. He explains the molecular mechanism of KEAP1 as a ubiquitin E3 ligase and stress sensor, highlighting the ‘hinge and latch’ model of NRF2 binding and the role of reactive cysteines in sensing electrophiles and reactive oxygen species. He introduces the concept of a ‘cysteine code’ and discusses the distinct sensors for electrophiles and ROS. The talk then shifts to the clinical relevance, showing that NRF2-activated cancers are highly malignant and resistant to therapy, with somatic mutations in the ETGE and DLG motifs. He also discusses the therapeutic potential of NRF2 inducers, such as dimethyl fumarate and omaveloxolone, and the need for new protein-protein interaction inhibitors. The lecture concludes with a comparison to the HIF-1α oxygen sensing system and emphasizes the importance of NRF2 in redox signaling and disease.

Critical Evaluation

The lecture provides a comprehensive and authoritative overview of the KEAP1-NRF2 pathway, delivered by a pioneer in the field. The scientific content is rigorous, with a clear logical progression from basic molecular mechanisms to clinical implications. The speaker effectively integrates historical context, experimental evidence, and translational relevance. The use of specific examples, such as the identification of cysteine sensors and the hinge-latch model, demonstrates a deep understanding of the subject. The sources cited are primarily the speaker’s own research and well-established literature, lending credibility to the presentation. However, the talk is a conference presentation, so it lacks the detailed methodological descriptions and peer-review scrutiny of a formal publication. Some concepts, such as the ‘cysteine code’, are introduced without extensive elaboration, which may leave non-specialists with questions. The adéquation between title and content is strong, as the talk directly addresses the role of oxidative stress in cancer therapy response. Overall, the lecture is a valuable resource for researchers and advanced students in redox biology and oncology.
