Project description:The imbalance of cellular homeostasis during oncogenesis together with the high heterogeneity of tumor-associated stromal cells have a marked effect on the repertoire of the proteins secreted by malignant cells (the secretome). Hence, the study of tumoral secretomes provides insights for understanding the cross-talk between cells within the tumor microenvironment as well as the key effectors for the establishment of the pre-metastatic niche in distant tumor sites. In this context, we performed a proteomic analysis of the secretomes derived from four cell lines: (i) a paired set of fibroblasts - Hs 895. T, a cell line obtained from a lung node metastatic site from a patient who had melanoma and Hs 895.Sk, a skin fibroblast cell line (derived from the same patient); (ii) two malignant metastatic melanoma cell lines - A375, a malignant melanoma cell line from primary source and SH-4, a cell line derived from pleural effusion of a patient with metastatic melanoma. Clustering of expression profiles together with functional enrichment revealed patterns that mirrored each cell type (skin fibroblasts, cancer-associated fibroblasts and metastatic cells). These patterns might be the result of cell-specific protein expression programs and may serve as basis for further proteomic analysis of melanoma cell lines secretomes.

Project description:MITF plays critical role in development and differentiation of melanocytes and in the context of melanoma, as a lineage survival oncogene. Given its crucial role in melanoma biology, it is very difficult to generate complete knock-out (KO) of MITF and in our hands, those that were generated appear to behave differently than the effect observed using siRNA mediated knock-down, possibly indicative of selection. In order to overcome the limitation of the transient effect of siRNA and study the effect of MITF depletion over a longer period of time, we carried out transcriptomic analyses of Doxycycline inducible shMITF knock down after 8 days in 2 melanoma cell lines MeWo (CVCL_0445) and SkMel 28 (CVCL_0526)

Project description:We report that miR-211 loss-of-function in the pigmented melanoma cell line SKMEL-28 slowed growth and invasion in vitro, inhibited phosphoinositol-3-kinase (PI3K) signaling, rendered these melanoma cells metabolically vulnerable by attenuating mitochondrial respiration and tricarboxylic acid (TCA) cycling and inhibited melanoma growth in vivo.

Project description:We investigated the miRNAome in human melanocyte and melanoma cell lines using high-throughput RNA sequencing. We identified a group of dysregulated miRNAs by comparing the miRNA expression profiles among melanoma cell lines. Target genes of these miRNAs participate in functions associated with the cell cycle and apoptosis. Gene networks were built to investigate the interactions of genes during melanoma progression. We identified that the key genes that regulate melanoma cell proliferation were regulated by miRNAs. Our findings provide further knowledge regarding the mechanisms of melanoma development. miRNA profiles of melanocyte (HEMn-LP), low metastatic melanoma (A375) and high metastatic melanoma (A2058) cell line were generated using Illumina GA

Project description:Purpose. Aggressiveness is a crucial issue related to cutaneous melanoma malignancy and its high metastatic potential. Aim of this work is to identify new pathways or molecules controlling melanoma cell aggressiveness. Proliferation, migration and invasion capability under serum stimulation were analyzed in 12 human metastatic melanoma cell lines to identify the most aggressive ones as a model. The most proliferating/invading (defines as the most aggressive) A375 cell line was compared to the less aggressive one, Sk mel 28 by means of different approaches: 1) transcriptomic analysis by ILLUMINA platform; 2) proteomic study through LC-MS/MS analysis; 3) multiplexed assay to measure secretion of cytokines in conditioned media bioinformatic analysis was then carried out. Two groups of cells significantly differing in aggressiveness were identified and 2 cell lines, namely A375 and SK-Mel-28 were selected as model of the most and the less aggressive phenotype, respectively. A multi-omic analysis of several experimental datasets derived from transcriptomic, proteomic (mass spectrometric) and cytokinomic data was then carried out via Ingenuity Pathway Analysis (IPA) software. Analysis of upstream regulators and network analysis, indicated that the expression of tumor necrosis factor (TNF) were significantly differently expressed and functioning. The involvement of these pathways was confirmed by functional validation studies as zymography and proliferation studies and the most significantly upregulated pathway (TNF-alfa) was tested. Five melanoma cell lines with different MAGS were treated with an anti-TNFα monoclonal antibody and the most aggressive ones were highly significantly affected.
