WebApr 5, 2024 · Nrf2-specific short interfering RNA (siRNA) molecules were synthesized by the Shanghai Genechem Company. The transfection was performed using Lipofectamine 2000, and cells were transfected for 48 h at 37°C. The transfection efficiency was confirmed by Western blotting. 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 ].
