Abstract excerpt
Activation of the ras oncogene in primary human esophageal carcinomas and cell lines established from such carcinomas was analyzed using the polymerase chain reaction (PCR)-direct sequencing method. This analysis revealed a GC----AT transition at the second base in the 12th codon of the c-Ki-ras gene in TE1 and TE2 esophageal carcinoma cell lines. In contrast, no point mutation was detected in the 12th, 13th, and...
