Analysis of BRAF gene mutation in lung cancer and esophageal cancer

The RAF-MEK-ERK is an important signaling pathway that controls cellular proliferation, differentiation and survival. Recent reports indicate that R-RAF is mutated at a high frequency in human cancer. The mutations are clustered in the glycine-rich loop and activation segment which are encoded by exon 11 and exon 15, respectively. Among these mutations, V600E is the most prevalent found in varieties of human cancers, include melanoma and thyroid carcinomas. In this thesis, we analyzed 86 human cancer specimens, including 62 lung cancers and 24 esophageal cancers, for the mutation of exons 11 and 15 by PCR and direct DNA sequencing. However, we can not detect any mutation in these two exons in these clinical samples, these results suggest indicating that BRAF mutation might be rare and analysis of larger sample size is needed to confirmed this conclusion.
