Gene expression signature associated with BRAF mutations in human primary cutaneous melanomas.

ABSTRACT: With the aim to correlate BRAF mutation status with gene expression in human primary cutaneous melanomas, and thus to get more insight on the consequences of BRAF mutation on cell biology, we analyzed all expression data obtained in melanomas from which DNA was extracted from the same tissue slides that were used for the expression study. A cohort of 69 frozen primary melanoma whose oligonucleotide micro-array expression data were available, were genotyped for BRAF and NRAS genes. The expression data from these melanomas were re-analyzed according to BRAF mutational status. A set of 250 probes representing 209 genes that were significantly (raw P< or =0.001) associated with BRAF mutation status was identified and 17 of these were previously shown to be implicated in cutaneous melanoma prog
