  Glutathione Adduct of Methylmercury Activates the Keap1–Nrf2 Pathway in SH-SY5Y Cells

  摘要：

  Methylmercury (MeHg) reacts readily, with GS leading to the formation of a MeHg SG adduct that is excreted into extracellular space through rnultidnig-resistance-associated protein (), which is regulated by the transcription factor Nrf2. We, previously reported that MeHg covalently modifies Keapl and activates Nrf2 in human neuroblastoma SH-SYSY cells. In the,study presented here, we examined whether the MeHg SG adduct could also modulate the Keapl Nrf2 pathway because the formation Of the Hg-S bond is believed to be reversible in the presence of a nucleophile SH-SYSY cells exposed to the synthetic ethyl monoester of the MeHg SG adduct (which is hydrolyzed by cellular esterase(s) to give the MeHg-SG adduct) exhibited a concentration-dependent,e cellular toxicity that was enhanced by pretreatment with a specific MRP inhibitor. As expected, the MeHg SG adduct was able to modify cellular proteins in the SH-SYSY cells and purified Keap1. We also found that this prodrug, as well as MeHg, causes e cellular Keapl in the cells to be modified, resulting in Nrf2 activation and, thereby, the upreplation of the downstream genes. These results suggest that the MeHg-SG adduct is not electrophilic but that it modifies protein thiols (including Keapl) through S-transmercuration and that rapid Nrf2-dependent excretion of the:MeHg-SG adduct is essential in decreasing the cytotoxicity of MeHg.
