Project description:Patients with the genetic skin blistering disease recessive dystrophic epidermolysis bullosa (RDEB) develop aggressive and metastatic cutaneous squamous cell carcinoma which is the principal cause of premature mortality in this patient group. We performed gene expression profiling of RDEB-SCC cells compared to RDEB keratinocytes in order to identify tumor-specific molecules that could potentially be exploited for detection, diagnosis, and therapy of this devastating disease.

Project description:Recessive dystrophic epidermolysis bullosa (RDEB) is a monogenetic skin disorder caused by mutations in the COL7A1 gene. Missing type VII collagen leads to severe blister formation and frequent chronic wounds. Patients suffering from RDEB are prone to develop particulary aggressive squamous cell carcinoma (SCC), representing the major cause of mortality. This dataset provides Affymetrix microarray (miRNA4.1) based whole transcriptome data on RNA isolated from cultured primary keratinocytes (KC) as well as squamous cell carcinoma (SCC). Cells were derived from punch biopsies or tumor resections from either healthy donors or SCC patients with or without the diagnosis recessive dystrophic epidermolysis bullosa (RDEB). Primary KC and SCC were cultivated in fully defined medium till subconfluency. Total RNA was isolated and microarray assay performed.

Project description:Cutaneous squamous cell carcinoma (cSCC) is the leading cause of death in recessive dystrophic epidermolysis bullosa (RDEB) patients but remains poorly studied on a proteomic level. We aim to characterize the RDEB-SCC proteome by comparing it to the proteomes of UV-light induced cSCC of non-aggressive and aggressive behavior with which RDEB cSCC share either the well-differentiated morphology or the aggressive behavior, respectively. We applied a direct trypsinization protocol using an acid labile surfactant and label-free quantitation to study formalin-fixed, paraffin-embedded tissues from patients with RDEB cSCC (n=6), low-risk cSCC (n=5) and metastasizing cSCC (n=13) by liquid chromatography tandem-mass spectrometry.

Project description:Recessive dystrophic epidermolysis bullosa (RDEB) is a monogenetic skin disorder caused by mutations in the COL7A1 gene. Missing type VII collagen leads to severe blister formation and frequent chronic wounds. Patients suffering from RDEB are prone to develop particulary aggressive squamous cell carcinoma (SCC), representing the major cause of mortality. This dataset provides Affymetrix microarray (ClariomD) based whole transcriptome data on RNA isolated from cultured primary RDEB keratinocytes (RDEB-KC) as well as RDEB squamous cell carcinoma (RDEB-SCC). Cells were derived from punch biopsies or tumor resections from patients with confirmed diagnosis recessive dystrophic epidermolysis bullosa (RDEB). Primary KC and SCC were cultivated in fully defined medium till subconfluency. Total RNA was isolated and microarray assay performed.

Project description:Recessive dystrophic epidermolysis bullosa, Kindler syndrome and xeroderma pigmentosum C, are three cancer-prone genodermatoses whose causal genetic mutations cannot fully explain, on their own, the array of associated phenotypic manifestations. Recent evidence highlights the contributing role of the stromal microenvironment in the pathology of these disorders. To investigate common mechanisms that contribute to the pathogenic role played by dermal fibroblasts, we conducted a comparative gene expression analysis by RNA-Seq.

Project description:Recessive dystrophic epidermolysis bullosa (RDEB) is a genodermatosis characterized by fragile skin forming blisters that heal invariably with scars. It is due to mutations in the COL7A1 gene encoding type VII collagen, the major component of anchoring fibrils connecting the cutaneous basement membrane to the dermis. Identical COL7A1 mutations often result in inter- and intra-familial disease variability, suggesting that additional modifiers contribute to RDEB course. Here, we studied a monozygotic twin pair with RDEB presenting markedly different phenotypic manifestations, while expressing similar amounts of collagen VII. Genome-wide expression analysis in twins' fibroblasts showed differential expression of genes associated with TGF-β pathway inhibition. In particular, decorin, a skin matrix component with anti-fibrotic properties, was found to be more expressed in the less affected twin. Accordingly, fibroblasts from the more affected sibling manifested a profibrotic and contractile phenotype characterized by enhanced α-smooth muscle actin and plasminogen activator inhibitor 1 expression, collagen I release and collagen lattice contraction. These cells also produced increased amounts of proinflammatory cytokines interleukin 6 and monocyte chemoattractant protein-1. Both TGF-β canonical (Smads) and non-canonical (MAPKs) pathways were basally more activated in the fibroblasts of the more affected twin. The profibrotic behaviour of these fibroblasts was suppressed by decorin delivery to cells. Our data show that the amount of type VII collagen is not the only determinant of RDEB clinical severity, and indicate an involvement of TGF-β pathways in modulating disease variability. Moreover, our findings identify decorin as a possible anti-fibrotic/inflammatory agent for RDEB therapeutic intervention. Primary fibroblast cultures from biopsies from two twins affected by recessive dystrophic epidermolysis bullosa were analyzed. Each hybridization was performed in biological triplicate and in technical duplicate.

Project description:Recessive dystrophic epidermolysis bullosa (RDEB), intractable skin genetic disease, is caused by mutations in COL7A1. Most RDEB patients have mutations in a compound heterozygous manner. We established an RDEB model mouse with patient type mutations in a compound heterozygous manner. We selected two mutations, c.5818delC and E2857X, which is recurrently identified in human RDEB cohort, and introduced the mutations at corresponding locations of the mouse genome. We analyzed the established mouse by single cell RNA-seq to clarify how loss of functional type VII collagen impact on the integrity of skin.
