Project description:Setleis Syndrome is a rare type of facial ectodermal dysplasia characterized by an aged leonine appearance with puckered skin about the eyes, absent eyelashes on both lids or multiple rows on the upper lids and none on the lower lids, eyebrows that slant sharply upward laterally, and a rubbery feel of the nose and chin. Some of the patients showed bilateral temporal marks superficially like forceps marks and like the lesions seen in focal facial dermal dysplasia. We have evidence that Setleis Syndrome is caused by nonsense mutations in the gene coding for the small bHLH transcription factor known as TWIST2 in Puerto Rican and Omani patients. We performed expression microarray analysis of RNA samples derived from skin fibroblasts grown from skin biopsies of Setleis Syndrome patients and normal controls in order to identify genes potentially involved in facial development and the pathogenesis of Setleis Syndrome. A total of 4 control and 4 Setleis Syndrome RNA samples were hybridized to U133 plus 2 Affymetrix 3'IVT arrays in the Mount Sinai School of Medicine Microarray Core Facility.

Project description:We found a candidate region (with 55 known or predicted genes) that was found to linkage to the MACS syndrome. Because it is transmitted in an autosomal recessive fashion, and given the fact most recessive disorders are caused by loss-of-function mutations often resulting in decreased mRNA levels, we hypothesized that screening the expression of the various genes located within the disease interval may point to candidate genes of interest. We therefore established fibroblast cell lines from punch skin biopsies obtained from 2 patients and 4 ethnically matched healthy controls. We then compared global gene expression using microarrays in the 6 cell lines (all genes contained within the disease interval were represented on the array).

Project description:Bloom syndrome is a rare autosomal recessive genetic instability and cancer predisposition syndrome caused by loss of function mutations in the BLM RECQ helicase gene. To ask if some of the distinctive pathological features of Bloom syndrome might reflect altered gene expression, we analyzed global mRNA and miRNA expression in fibroblasts from 16 patients and 15 matched normal controls, and in control primary diploid fibroblasts depleted of the BLM protein. We document significant differential expression of both protein-coding genes and miRNAs with well-characterized cancer associations in BLM-deficient cells. Differences in expression correlated significantly with G4 motifs, which are associated with potential to form G-quadruplex structures. These results indicate that BLM helicase may modulate gene expression by regulating the in vivo stability of G-quadruplex structures, and identify sets of genes and miRNAs whose expression, when altered, may drive the pathogenesis of Bloom syndrome and associated cancers. Global profiling of mRNA and miRNA expression was analyzed in primary fibroblasts from 16 patients and 15 matched normal controls, and in 9 primary diploid fibroblasts depleted of BLM protein by BLM-specific (3), control (3) and scrambled (3) shRNA.

Project description:This gene set contains skin fibroblasts from either labia majora of 46,XY sex reversed females having complete androgen insensitivity syndrome due to inactivation mutations of the androgen receptor gene and from the scrotum of normal males. Both, labia majora and scrotum origin from the same embryological anlagen, the labioscrotal swellings. The phenotypic difference is due to androgen dependent virilization in males. This is not possible in 46,XY patients with complete androgen insensitivity syndrome because the androgen receptor pathway is knocked out. A cell type comparison design experiment design type compares cells of different type for example different cell lines. Cell Line: genital skin fibroblasts from different locations mutant line: normal 46,XY male and 46,XY sex reversed female due to inactivating mutations of the androgen receptor gene Computed

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 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.
