factor (erythroid-derived 2)-like 2/kelch-like ECH-associated protein 1 (NRF2/ KEAP1) pathway, the nuclear factor kappa-light-chain-enhancer of activated B cells pathway (NF-κB), and various epigenetic pathways [35, 38]. Further experimental work is required to fully characterize and distinguish the molecular mechanisms of the pathways affected by chronic exposure to arsenic.
