(Submitter supplied) Melanoblastoma-bearing Libechov minipigs (MeLiM) provide an animal model for the study of spontaneous cutaneous melanoma. We compared the serial analysis of gene expression (SAGE) profile between normal skin melanocytes and melanoma cells from a pulmonary metastasis of MeLiM. Keywords: disease state study

(Submitter supplied) T1C3 is a clonal cell line from a human melanoma tumor, expressing PNA lectin, and characterized by a high capacity of dermal invasion. IC8 is a clonal cell line from a human melanoma tumor, negative for PNA lectin, and non-invasive. To identify new gene markers involved in the mechanisms of early invasion, oligonuclotide microarrays were used to assess transcriptional chnages between the two cell lines.

(Submitter supplied) Melanoma can progress rapidly from a slow-growing surgically curable lesion to aggressive metastatic disease, with high mortality and poor response to current therapies. The mechanisms underlying melanoma progression and resistance to therapeutic agents are not well understood. There are few treatment options for melanoma once it has metastasized, and new biomarkers that aid diagnosis, predict clinical outcome, and suggest new therapies are required. more...

(Submitter supplied) Despite advances in therapeutics, the progression of melanoma to metastasis still confers a poor outcome to patients. Nevertheless, there is a lack of biological models to understand cellular and molecular changes taking place along disease progression. Here, we analyzed the transcriptome of a multi-stage murine model of melanoma progression comprising a non-tumorigenic melanocyte lineage (melan-a), pre-malignant melanocytes (4C), non-metastatic (4C11-) and metastasis-prone (4C11+) melanoma cells. more...

(Submitter supplied) Characterized by striking metastatic propensity and chemoresistance, melanoma is among the most lethal cutaneous malignancies. The transcription factor ATF2 was shown to elicit oncogenic activities in melanoma, and its inhibition attenuates melanoma development. Here, a mouse model engineered to express a transcriptionally inactive form of Atf2 (Atf2?8,9) was found to be sufficient to induce nevi formation and, when crossed with BrafV600E animals, to promote melanoma development. more...

(Submitter supplied) Purpose: We hypothesized that embryonic melanocytic pathways would be reinitiated in melanoma metatastasis. To identify nove melanoblast signaling pathways with which to explore our hypothesis we used the inducible Dct-GFP mouse model, in which GFP is expressed in both immature melanoblasts and mature melanocytes. Mouse melanoblasts/melanoytes were extracted using Fluorescence Activated Cell Sorting and transcriptomes were analyzed using RNA-sequencing. more...

(Submitter supplied) Ultraviolet (UV) radiation is a major melanoma risk factor, yet underlying mechanisms remain poorly understood. Here we introduce a mouse model permitting fluorescence-aided melanocyte imaging and isolation following in vivo UV irradiation. We use expression profiling to show that activated neonatal skin melanocytes isolated following a melanomagenic UVB dose bear a distinct, persistent interferon-response signature, including genes associated with immunoevasion. more...

(Submitter supplied) This study aimed to understand the role of ILF2 upregulation in metastatic melanoma cutaneous progression and DNA damage response. The goal of RPPA analysis was to determine the protein expression profiles in DP-0574 and IM-0223 melanoma cell lines with ILF2 overexpression (ILF2-OV) or control empty vector (EV). By analysis of RPPA in both metastatic melanoma cell lines, we found that ILF2-OV controls significantly increased RAD50 expression.

(Submitter supplied) Cutaneous melanoma is an aggressive type of skin cancer with a complex genetic landscape caused by the malignant transformation of melanocytes. The study aimed at providing an in-silico network model based on the systematic profiling of the melanoma-associated genes considering germline mutations, somatic mutations, and genome-wide association studies (GWAS) signals (collectively melanoma risk genes). more...

(Submitter supplied) To build a pre-cancer atlas for melanoma that reveals early events in disease initiation and immune response, we performed RNA sequencing of 222 histologically distinct micro-regions (~5-20 cells per region) extracted from 3 formalin-fixed paraffin-embedded tissue sections collected from a melanoma patient. These sections capture multiple phases of disease progression from melanoma in situ to metastatic invasive melanoma and areas of effective immune surveillance. more...
