Chronic exposure to aflatoxin B1 (AFB1) is linked to the development of hepatocellular carcinoma (HCC). To identify differentially methylated genes involved in AFB1-induced cell transformation, we analyzed DNA methylation patterns in immortal human hepatocyte L02 cells expressing an oncogenic H-Ras allele (L02R cells) and AFB1-transformed L02R (L02RT-AFB1) cells by performing genome-wide methylation...
Aflatoxin B1 (AFB1) is a well-known human hepatotoxicant and genotoxicant. Recent studies demonstrated that aberrant miRNA expression patterns were correlated with the cellular and genetic lesions induced by chemicals. To explore the role of miRNAs in AFB1-induced hepatotoxicity and genotoxicity, we examined alterations in miRNA expression patterns in F334 rat livers after exposure to 100 μg/kg or...
