Abstract excerpt
To investigate the molecular pathogenesis of human gastric cancers the p53 gene, a suppressor oncogene, was analyzed in 12 human gastric cell lines. Southern blot and Northern blot analysis revealed a total deletion of p53 gene in KATO-III cells but no major abnormality of p53 gene in other cell lines. By the use of the reverse-transcriptase polymerase chain reaction and direct sequencing 7 cell lines showed...
