原始语种摘要: In addition to direct antioxidative effects, Maillard reaction products (MRPs) could increase the antioxidative capacity of cells through the induction of cytoprotective enzymes. Since many of those enzymes are regulated by the transcription factor Nrf2, the effect of MRPs on nuclear translocation of Nrf2 in macrophages and Caco-2 cells was investigated. Stimulation of both cell types by MRPs showed a concentration-dependent significant increase in nuclear translocation of Nrf2 up to fivefold after short-term (2 h) and up to 50-fold after long-term treatment (24 h). In intact human gut tissue, nuclear translocation of Nrf2 was significantly twofold increased after short-term incubation. To study the activation mechanisms, macrophages and Caco-2 cells were stimulated with MRPs in the...
