WebFeb 22, 2024 · Among the 77 NRF2-positive cases, NRF2 staining were localized in cytoplasm in 46 (59.7%) cases, in nucleus in 14 cases (18.2%), and in both cytoplasm and nucleus in 17 cases (22.1%) (Fig. 1A–E). WebUnder normal conditions, Nrf2 is maintained at low basal levels in the cytoplasm because of its degradation by the UPS. In a normal state, Kelch-like ECH-associated protein 1 (Keap1), an adaptor protein for a cullin 3 (Cul3)-based ubiquitin E3 ligase, tightly binds to Nrf2, targeting Nrf2 for degradation by the proteasome [ 158 , 159 , 160 ].

WebDec 6, 2016 · In the normal hippocampus, Nrf2 is expressed in neurons and predominantly localised in the nucleus. In the AD brain, Nrf2 predominantly localises in the cytoplasm of hippocampal neurons and not a component of Aβ plaques or NFTs. Immunoblotting studies suggested that the Nrf2 levels were reduced in AD cases (Ramsey et al. 2007).
WebApr 21, 2016 · Under normal conditions, Nrf2 is sequestered in cytoplasm by Keap1. In stressful conditions the modification of –SH groups in Keap1 or phosphorylation of Nrf2 facilitate the dissociation of Nrf2 from Keap1 as well as translocation of Nrf2 into the nucleus. After binding Maf proteins, Nrf2 activates antioxidant response element (ARE) … WebUnder normal conditions, Nrf2 is located in the cytoplasm and binds to Kelch-like ECHassociated protein (Keap1), which blocks Nrf2 from entering the nucleus (6)(7)(8).
