The KEAP1–NRF2 System in Cancer
Cancer cells first adapt to the microenvironment and then propagate. Mutations in tumor suppressor genes or oncogenes are frequently found in cancer cells. Comprehensive genomic analyses have identified somatic mutations and other alterations in the KEAP1 or NRF2 genes and in well-known tumor suppressor genes or oncogenes, such as TP53, CDKN2A, PTEN, and PIK3CA, in various types of cancer. Aber...
متن کاملPhysical and Functional Interaction of Sequestosome 1 with Keap1 Regulates the Keap1-Nrf2 Cell Defense Pathway*
Nrf2 regulates the expression of numerous cytoprotective genes in mammalian cells. The activity of Nrf2 is regulated by the Cul3 adaptor Keap1, yet little is known regarding mechanisms of regulation of Keap1 itself. Here, we have used immunopurification of Keap1 and mass spectrometry, in addition to immunoblotting, to identify sequestosome 1 (SQSTM1) as a cellular binding partner of Keap1. SQST...
متن کاملA load of mice to hypergravity causes AMPKα repression with liver injury, which is overcome by preconditioning loads via Nrf2
An understanding of the effects of hypergravity on energy homeostasis is necessary in managing proper physiological countermeasures for aerospace missions. This study investigated whether a single or multiple load(s) of mice to hypergravity has an effect on molecules associated with energy metabolism. In the liver, AMPKα level and its signaling were repressed 6 h after a load to +9 Gz hypergrav...
متن کاملTargeting the KEAP1-NRF2 System to Prevent Kidney Disease Progression.
BACKGROUND Nuclear factor erythroid 2-related factor 2 (NRF2) is a critical transcription factor for the antioxidative stress response and it activates a variety of cytoprotective genes related to redox and detoxification. NRF2 activity is regulated by the oxidative-stress sensor molecule Kelch-like ECH-associated protein 1 (KEAP1) that induces proteasomal degradation of NRF2 through ubiquitina...
متن کاملThe antioxidant defense system Keap1-Nrf2 comprises a multiple sensing mechanism for responding to a wide range of chemical compounds.
Animals have evolved defense systems for surviving in a chemically diverse environment. Such systems should demonstrate plasticity, such as adaptive immunity, enabling a response to even unknown chemicals. The antioxidant transcription factor Nrf2 is activated in response to various electrophiles and induces cytoprotective enzymes that detoxify them. We report here the discovery of a multiple s...
