Research Abstract

S100A8/A9 proteins are known to be involved in inflammation and cancer immunity. We showed that exposure to arsenic induces expression of S100A9 in various types of cells and that transcription factor Nrf2 is involved in enhanced transcription of S100A9 gene. We also detected high concentrations of S100A8/A9 among the residents living in arsenic-endemic areas in Bangladesh, suggesting an important role of S100A8/A9 in arsenic intoxication.
