Metastatic melanoma, the primary cause of skin cancer-related death, warrants new therapeutic approaches that target the regulatory machinery at molecular level. While long noncoding RNAs (lncRNAs) are dysregulated in a number of cancer types, limited data are available on the expression and function of lncRNAs in melanoma metastasis. The primary objective of this study was to investigate the role of 6 metastasis-related lncRNAs in pairs of primary melanoma and matched lymph node metastatic tissues. Among the tested lncRNAs, HOTAIR was the most highly expressed in lymph node metastasis. The role of HOTAIR in melanoma cell motility and invasion was further evaluated by knocking down HOTAIR with siRNAs. Knockdown of HOTAIR resulted in the reduction of motility and invasion of human melanoma cell line A375, as assessed by wound healing assay and Matrigel-based invasion assay. siHOTAIR also suppressed the degradation of gelatin matrix, suggesting that HOTAIR promotes gelatinase activity. Together, our study shows that HOTAIR is overexpressed in metastatic tissue, which is associated with the ability of HOTAIR to promote melanoma cell motility and invasion. These data indicate that lncRNAs may be involved in the metastasis of melanoma and provide support for further evaluation of lncRNAs in melanoma.

Das metastasierende Melanom (MM) gehört zu den schwierig behandelbaren Malignomen, wobei Allgemeinzustand und Motivation des Patienten neben Zahl und Lokalisation der Metastasen das therapeutische Vorgehen bestimmen. Solitäre Metastasen in Lunge, ZNS, Weichteilen und Lymphknoten sollten primär chirurgisch entfernt werden. Multiple Metastasen, insbesondere abdominal, werden nur in Ausnahmefällen chirurgisch angegangen. Hier ist vielmehr ein systemische Chemoimmuntherapie angebracht. Aussichtsreiche Behandlungskonzepte beinhalten Interleukin-2, Interferon, und verschiedenen Zytostatika wie DTIC, Temozolamid, Vindesine oder Cisplatin. Bei ZNS- und Skelettfiliae ist die Radiotherapie einzusetzen. Durch diese Chemoimmuntherapien hat sich die Prognose des metastasierenden Melanoms bezüglich des Überlebens verbessert. Langfristig wird aber nur eine Kombination von zeitraubenden Multicenterstudien und experimentellen Ansätzen in der Lage sein, uns langsam an eine kurative Therapie heranzuführen.
