“In addition, we demonstrate that As2O3 markedly alters nuclear levels of Nrf2 and Bach1, two redox‐sensitive regulators of stress genes, and represses expression of the transcription factor EGR2 which is involved in mouse macrophage differentiation; such effects are reduced by N‐acetylcysteine.”
“Notably, As2O3 alters neither activity of the redox‐sensitive transcription factor Sp1 nor that of AP‐1 or NF‐κB. In contrast, N‐acetylcysteine , a potent cysteine reductive compound, significantly prevents up‐regulation of HMOX1, GCLM, and CXCL2 genes, and repression of MMP9 and CCL22 genes induced by As2O3.”
