(Submitter supplied) Metastatic melanoma develops once transformed melanocytic cells begin to de-differentiate into migratory and invasive melanoma cells with neural crest cell (NCC)-like and epithelial-to mesenchymal transition (EMT)-like features. However, it is still unclear how transformed melanocytes assume a metastatic melanoma cell state. Here, we define DNA-methylation changes that accompany metastatic progression in melanoma patients and discover Nuclear Receptor Subfamily 2 Group F, Member 2 – isoform 2 (NR2F2-Iso2) as an epigenetically regulated metastasis driver. more...

(Submitter supplied) Melanoma is a highly metastatic tumor type responsible of the large majority of the skin cancer-related deaths. Melanoma cells recapitulate the migratory and invasive nature of neural crest stem cells from which melanocytes arise. However, the mechanisms by which these developmental programs confer melanoma cells with more aggressive properties are not understood. Here we provide evidence for an epigenetically regulated developmental program that is aberrantly re-activated by melanoma cells to aid in the metastatic process. 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) Malignant melanoma is the most fatal skin cancer with a high degree of genetic and epigenetic aberrations.

(Submitter supplied) SOX9 is generally not expressed in melanomas with a high proliferative capacity but is expressed in melanomas with a high invasive capacity. Here we overexpress full length SOX9 in M010817, a melanoma cell culture with high proliferative capacity but low invasive capacity.

(Submitter supplied) The non-genetic mechanisms required to sustain malignant tumor state are poorly understood. During the transition from benign tumors to malignant carcinoma, tumor cells need to repress differentiation and acquire invasive features. Using transcriptional profiling of cancer stem cells (CSC) from benign tumors and malignant skin squamous cell carcinoma (SCC), we identified the nuclear receptor NR2F2 as uniquely expressed in malignant SCC. more...

(Submitter supplied) Epithelial-mesenchymal transition (EMT) and mesenchymal-epithelial transition (MET) facilitate breast cancer (BC) metastasis, however stable molecular changes that result as a consequence of these processes remain poorly defined. Therefore, we sought to identify molecular markers that could distinguish tumor cells that had completed the EMT:MET cycle in the hopes of identifying and targeting unique aspects of metastatic tumor outgrowth.Therefore, normal murine mammary gland (NMumG) cells transformed by overexpression of EGFR (NME) cells were cultured in the presence of TGF-beta1 (5 ng/ml) for 4 weeks, at which point TGF-beta1 supplementation was discontinued and the cells were allowed to recover for an additional 4 weeks (Post-TGF-Rec). more...
