Abstract
Both p53 and MDM2 genes are parts of a physiological pathway frequently impaired in human cancer. This is the report on the analysis of p53 and MDM2 genes in a group of four hepatocellular carcinoma cell-lines and one hepatoblastoma cell-line. Four cell-lines were screened for the presence of p53 mutations using the polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) method. Investigation of the MDM2 gene revealed neither gene amplification nor rearrangement in all cell-lines. However MDM2 mRNA in a hepatoblastoma cell line(HepG2) was elevated to about 2.4 times the level of normal human liver.
