Symposium Title: Bench to Bedside Translation for Pharmacological Regulation of NRF2 

Symposia Summary: NRF2 (Nuclear factor erythroid 2-related factor 2) is a key transcription factor for  regulation of cellular homeostatic. Its mode of action involves heterodimerization with other bZip transcription factors, of which the small MAF proteins F, G and K are the best characterized. The  heterodimer activates the expression of genes that contain an Antioxidant Response Element (ARE),  and these genes participate in protection against oxidative, inflammatory, metabolic or proteotoxic  stress. Given the tremendous impact of this protein in physiology and pathology, it is not surprising  that it has attracted a great deal of attention by the biomedical community. Moreover, contrary to  most transcription factors, NRF2 is amenable to pharmacological activation by selectively inhibiting its  degradation. The main repressor of NRF2 is the druggable E3 ligase adapter Kelch-likeECH-associated  protein1 (KEAP1). Under unstressed conditions, KEAP1 targets NRF2 for Rbx1/Cullin 3-dependent  ubiquitination and proteasomal degradation, but this repressor activity is blocked when specific  cysteine residues in this protein are oxidized, or form adducts with electrophilic molecules. A much less  explored mechanism of NRF2 repression is its glycogen synthase kinase (GSK-3)- mediated phosphorylation, which creates a phosphorylation-dependent site for interaction with the E3-ligase  adapter β-transducin repeat-containing protein (β-TrCP). Binding of beta- TrCP to GSK-3- phosphorylated NRF2 leads to Rbx1/Cullin1-mediated ubiquitination and proteasomal degradation of  NRF2. Therefore, KEAP1 and β-TrCP complement each other in NRF2 regulation under oxidative stress  and cell signaling, respectively.
