Abstract :
The BRAF gene is mutated in 66% of melanomas and less frequently in various human cancers. More than 80% of these mutations are T to A transversions at nucleotide 1796 (T1796A), leading to a substitution of glutamic acid for valine at amino acid 599 (V599E). We established a new method for rapidly detecting V599E mutations using real-time polymerase chain reaction and melting curve analysis. Furthermore, we examined mutations in gastrointestinal cancer cell lines using this method. We found a mutation in 1 of 12 (8%) colorectal cancer cell lines, but no mutation was detected in 9 gastric cancer cell lines. These results suggest that the BRAF mutation is unlikely to be involved in gastric carcinogenesis.
