Exposure to aflatoxin B 1 (AFB 1 ) is one of the risk factors for developing hepatoma. In rats, activation of the ras gene is a prevalent event in AFB 1 -induced hepatocarcinogenesis. It is not clear whether a similar event occurs in humans. By analysis of codon 249 of the p53 gene, six of 36 human
