Description
The two most common melanoma histopathologic subtypes, superficial spreading (SSM) and nodular melanoma (NM), are believed to represent sequential phases of linear progression from radial to vertical growth. Studies suggest, however, that SSM and NM are biologically distinct. We utilized an integrative genomic approach to examine the possibility that SSM and NM are the result of independent pathways characterized by unique molecular alterations. Cell lines including SSM, NM, metastatic melanoma, and melanocyte controls were evaluated for copy number changes and differential mRNA expression using single nucleotide polymorphism array (SNP 6.0, Affymetrix) and gene array (U133A 2.0, Affymetrix). Data sets were integrated to identify copy number alterations that correlated with gene expression, and array results were validated using immunohistochemistry on human tissue microarrays (TMAs) and an external data set. The functional effect of genomic deletion was assessed by lentiviral overexpression. Integrative genomics revealed 8 genes in which NM/SSM-specific copy number alterations were correlated with NM/SSM differential gene expression (P<0.05, Spearmans rank). Pathways analysis of differentially expressed genes (N=114) showed enrichment for metabolic-related processes. SSM-specific genomic deletions (DIS3, MTAP, G3BP2, SEC23IP, USO1) were verified in an expanded panel of cell lines, and forced overexpression of MTAP in SSM resulted in reduced cell growth. Metabolism-related gene ALDH7A1 was verified as overexpressed in NM using human TMAs.The identification of recurrent genomic deletions in SSM not present in NM challenges the linear model of melanoma progression and supports the unique molecular classification of SSM and NM.

Description
To identify the true molecular features of the Ebf2+ cells, we performed microarray analysis of freshly sorted CD45-TER119-Ebf2+ and Ebf2- cells. This allowed for the detection of 1968 genes that were 2-fold differentially expressed in Ebf2+ and Ebf2- cells. Among these, 1075 genes were upregulated and 893 genes including Ebf2, were downregulated in the Ebf2- as compared to the Ebf2+ cells. These include Nov, Fmod, Ndn, Dcn, Ctgf, Angiopoietin like-1(Angptl1), Fn1 and Jag1, some of which has been reported to be expressed in culture-selected MSCs. Furthermore, consistent with antigen expression analysis by FACS, the Ebf2+ cells highly expressed transcripts of Pdgfra, Pdgfrb, Sca1/Ly6a, Thy1 and Itga7 and Itgav, that have been suggested to be linked to MSCs. Nestin was mainly expressed in the Ebf2+ cells whereas it was hardly detectable in the Ebf2- cells. Altogether, molecularly, the Ebf2+ cells displayed features of a MSC.
