Microphthalmia-Associated Transcription Factor Gene Amplification in Metastatic Melanoma Is a Prognostic Marker for Patient Survival, But Not a Predictive Marker for Chemosensitivity and Chemotherapy Response

Abstract excerpt

PURPOSE: The microphthalmia-associated transcription factor (MITF) is regarded as a key oncogene of the melanocytic lineage since it was detected by a genome-wide analysis to be strongly amplified in 15% to 20% of metastatic melanomas. MITF gene amplification was shown to be associated with a reduced survival in metastatic melanoma patients, and reduction of MITF activity was shown to sensitize melanoma cell...
