[A molecular genetic analysis of the 12th codon of the Ha-ras-1 proto-oncogene in human carcinoma and stomach ulcer cells].

Abstract

A method of the restriction analysis by Msp I enzyme has been used to analyze the 12th codon of Ha-ras-1 protooncogene in 10 human carcinomas and in the stomach mucosa adjacent to them their 5 metastases into the regional lymph nodes and in 2 ulcers. No point mutation was found.
