Microarray profiling is a powerful approach to establish gene expression patterns for different histopathological stages of a malignancy, and at the same time, to identify individual genes that may have important functions in the early and/or advanced stages of a neoplasm. To identify genes that hitherto have not been shown to be expressed or play a role in advanced-stage melanomas, we conducted microarray analyses with RNAs from primary melanoma and melanoma-positive lymph node specimens. Using RT-PCR, quantitative, real-time RT-PCR, and fluorochrome oligonucleotide-based optical imaging, we established the level and pattern of expression of five of the identified known genes [Suppression of Tumorigenicity 13 (ST13), Cystatin 8 (CST-8), Dyskeratosis Congentia 1 (DKC1), Neuroendocrine Secretory Protein 55 (NESP55), Niemann-Pick Disease, type C2 (NP-C2)], and a gene with unknown function (16.7 kD Hypothetical Protein) in benign and atypical nevocytic lesions, advanced-stage melanomas, and melanoma-positive lymph nodes.
