Abstract
AIM: To investigate ras gene mutations and farnesyltransferase (FTase) β mRNA expression in Epstein-Barr virus(EBV)-associated gastric carcinoma (EBVaGC), EBV-negative gastric carcinoma (EBVnGC) with matched clinico-pathological parameters and corresponding adjacent tissues of gastric carcinoma.
METHODS: The mutations of ras gene were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and the expression of FTase β mRNA was tested by reverse transcription PCR (RT-PCR) in 13 EBVaGCs, 45 EBVnGCs with matched clinicopathological parameters and 58 corresponding adjacent tissues of gastric carcinoma.
RESULTS: H-ras mutation at codon 12 was detected in 2(3.45%) cases of gastric carcinomas, both of which were EBVnGCs. No K-ras mutations occurred at codon 12 and 13 in all cases. The level of FTase β mRNA expression was 0 ......
