ObjectiveTo investigate the K-ras mutation pattern in six pancreatic cancer cell lines from Chinese patients.MethodsAll six cell lines were analyzed for mutation in exon 1 of the K-ras gene by polymerase chain reaction (PCR) and direct sequencing.ResultsAll 6 pancreatic cancer cell lines had GGT --> GTT mutation at K-ras codon 12 but no mutations at codon 13.ConclusionThe unique GGT --> GTT mutation at codon 12 plays a potential role in the carcinogenesis of pancreatic cancers in Chinese.
