Nickel(II) is a human carcinogen causing respiratory cancers. The purpose of this study was to determine whether Ni(II) may induce microsatellite mutations in human cells. We transfected the three human lung tumor cell lines A427, HCC15 and NCI-H2009 with a mammalian expression vector containing a (CA) 13 repeat in the coding sequences of the reporter hygromycin gene (hyg). A total of...
Hepatitis B virus (HBV) is a major etiological factor associated with hepatocarcinogenesis, but its role in the transformation process remains unclear. We previously documented the accumulation of genetic alterations in a HBV-transfected cell line. In the present study, we addressed the effect of HBV and its replication on the genome and phenotype of the host cell. Parental HBV-free Hep G2 cells and...
Over 10,000 mutations in the TP53 suppressor gene have been recorded in the International Agency for Research on Cancer (IARC) tumor data base. About 4% of these mutations are silent. It is a question whether these mutations play a role in tumor development. In order to approach this question, we asked whether the reported silent mutations are randomly distributed throughout the TP53 gene. The p53...
