摘要
Aflatoxin exposure is a crucial factor in promoting the development of primary hepatocellular carcinoma(HCC)in individuals infected with the hepatitis virus.However,the molecular pathways leading to its bioactivation and subsequent toxicity in hepatocytes have not been well-defined.Here,we carried out a genome-wide CRISPR-Cas9 genetic screen to identify aflatoxin B1(AFB1)targets.Among the most significant hits was the aryl hydrocarbon receptor(AHR),a ligand-binding transcription factor regulating cell metabolism,differentiation,and immunity.
