Genome-Wide Analysis of Somatic Copy Number Alterations (CGH, SNP) and Gene Expression (RNA-seq) in Metastatic Melanoma

Project description:All cancers are diseases of the genome. A combination of somatic point mutations, focal amplifications and deletions, and chromosome level aberrations conspire to disrupt gene expression and the interplay between signaling pathways that control normal growth and tissue homeostasis. Here we investigate somatic copy number abberations in metastatic melanomas. A metastatic melanoma was assayed on Affymetrix SNP arrays to detect copy number abberations. 7 cutaneous melanomas as well as their matched control ( peripheral blood lymphocytes (PBL) or Epstein-Barr virus transformed lymphoblastoid cell lines ) and 2 control melanocytes were assayed on Illumina SNP arrays. 7 metastatic melanomas were hybridized on Agilent CGH arrays using donor matched control as reference.

Regulators of NRAS-mediated transformation and melanoma tumor maintenance

Project description:Mutations in the NRAS oncogene are present in up to 20% of melanoma. Here, we show that interferon alpha-inducible protein 6 (IFI6) is necessary for NRASQ61K-induced transformation and melanoma growth. IFI6 was transcriptionally upregulated by NRASQ61K, and knockdown of IFI6 resulted in DNA replication stress due to dysregulated DNA replication via E2F2. This stress consequentially inhibited cellular transformation and melanoma growth via senescence or apoptosis induction depending on the RB and p53 pathway status of the cells. NRAS-mutant melanoma were significantly more resistant to the cytotoxic effects of DNA replication stress-inducing drugs, and knockdown of IFI6 increased sensitivity to these drugs. Pharmacological inhibition of IFI6 expression by the MEK inhibitor trametinib, when combined with DNA replication stress-inducing drugs, blocked NRAS-mutant melanoma growth. Collectively, we demonstrate that IFI6, via E2F2 regulates DNA replication and melanoma development and growth, and this pathway can be pharmacologically targeted to inhibit NRAS-mutant melanoma. YUGASP cells stably expressing a non-silencing shRNA or two individual shRNAs against IFI6 were used to prepare the total RNA, which was then used to analyze for gene expression using Illumina expression array.

Transcriptional response to TNF-alpha in a panel of 17 human melanoma cell lines

Project description:A panel of 17 human melanoma cell lines with known BRAF and NRAS mutation status was stimulated with TNF-alpha for 72 hours. The goal of the study was to correlate the transcriptional response in BRAF versus NRAS mutated melanoma cell lines. Total RNA was obtained from a panel of 17 human melanoma cell lines treated for 72 hours with TNF-alpha or left untreated. Gene expression profiling was done using the Illumina Human HT12 v4 platform.

Affymetrix 250K StyI SNP array data from PBMCs and cell lines of metastatic melanoma patients

Project description:Allele call files from on 250K StyI SNP array using DNA from 60 human cell lines from metastasized melanoma and from 44 corresponding peripheral blood mononuclear cells (CEL and CHP files provided). Analysis of the 250K StyI arrays was performed for 60 malignant melanoma cell lines derived from metastatic tumors of melanoma patients with GCOS and GTYPE (Affymetrix). In addition, DNA from peripheral blood mononuclear cells (PBMC) was available for 44 of the 60 samples.
