Project description:Overexpression of the oncogene HPV8 in keratinocytes of mice causes spontaneous papillomas to form in the skin. To study the expression profiles of skin cancer-associated fibroblasts, we performed RNA-sequencing of fibroblasts FACS-sorted from back skin tumors of HPV8 overexpressing mice.

Project description:Overexpression of activin by keratinocytes promotes HPV8-induced skin tumorigenesis in mice. Activin-promoted tumorigenesis is mediated via the stroma, specifically by cancer-associated fibroblasts (CAFs). To determine if activin alters the gene expression profile of skin fibroblasts, we performed RNA-sequencing of fibroblasts FACS-sorted from pre-cancerous ear skin of activin overexpressing mice. We found that activin induces a CAF-like gene expression profile of fibroblasts, leading to the upregulation of genes involved in proliferation, migration and cytoskeletal remodeling.

Project description:Overexpression of activin A by keratinocytes accelerates excisional wound healing in mice. Activin-promoted wound healing is mediated via the stroma, specifically by the wound immune cells and fibroblasts. To determine if activin A alters the gene expression profile of wound fibroblasts, we performed RNA-sequencing of fibroblasts FACS-sorted from excisional skin wounds of activin overexpressing mice. We found that activin induces a pro-fibrotic gene expression profile of these fibroblasts, leading to the upregulation of genes involved in collagen biosynthesis and remodeling.

Project description:Differentiation of fibroblasts to myofibroblasts is governed by the transforming growth factor beta (TGF-β) through a mechanism involving redox signaling and generation of reactive oxygen species (ROS). Myofibroblasts synthesize proteins of the extracellular matrix and display a contractile phenotype. Myofibroblasts are predominant contributors of wound healing and several pathological states, including fibrotic diseases and cancer. Inhibition of the ROS-generating enzyme NADPH oxidase 4 (NOX4) has been proposed to mitigate fibroblast to myofibroblast differentiation and to offer a therapeutic option for the treatment of fibrotic diseases. In this study, we addressed the role of NOX4 in physiological wound healing and in TGF-β-induced myofibroblast differentiation. We explored the phenotypic changes induced by TGF-β in primary skin fibroblasts isolated from Nox4-deficient mice by immunofluorescence, Western blotting and RNA sequencing. Mice deficient for Cyba, the gene coding for p22phox, a key subunit of NOX4 were used for confirmatory experiments as well as human primary skin fibroblasts. In vivo, the wound healing was similar in wild-type and Nox4-deficient mice. In vitro, despite a strong upregulation following TGF-β treatment, Nox4 did not influence skin myofibroblast differentiation. Nevertheless, up-regulation of the mitochondrial protein Ucp2 and the stress-response protein Hddc3, as well as down-regulation of Islr were observed in Nox4-deficient fibroblasts. Altogether, we provide extensive evidence challenging a profibrotic role of NOX4 in skin fibroblasts and show that Nox4 regulates Ucp2 and Hddc3 expression, suggesting the presence of a so far undescribed redox crosstalk between NOX4 and redox homeostasis in fibroblasts.

Project description:Orangutans are an endangered species whose natural habitats are restricted to the Southeast Asian islands of Borneo and Sumatra. For potential species conservation and functional genomics studies, we derived induced pluripotent stem cells (iPSCs) from cryopreserved skin fibroblasts obtained from captive orangutans. We report the gene expression profiles of iPSCs and skin fibroblasts derived from orangtuans. The overall goal was to evaluate gene expression biomarkers of pluripotency in iPSCs and skin fibroblasts derived from PBD-ZSD patients and healthy controls. Dermal fibroblast cultures from 2 orangutans were reprogrammed into iPSCs by transfection with retroviruses designed to express the human OCT4, SOX2, KLF4 and c-MYC cDNA. Fibroblasts and iPSCs were cultured in 1:1 ratio of DMEM:F12 medium supplemented with 20% KOSR (knock-out serum replacement) at 37°C with 5% CO2 until confluence for RNA extraction. The overall goal was to evaluate gene expression biomarkers of pluripotency in iPSCs and original fibroblast cultures.

Project description:Wound healing within the oral mucosa results in minimal scar formation compared to wounds within the skin. We have recently demonstrated distinct differences in the ageing profiles of cells (oral mucosal and patient-matched skin fibroblasts) isolated from these tissues. We hypothesize that the increased replicative potential of oral mucosal fibroblasts may confer upon them preferential wound healing capacities. Passage-matched early cultures of oral mucosal fibroblasts and skin fibroblasts demonstrated distinct gene expression profiles with a number of genes linked to wound healing/tissue repair. We analyzed the gene expression profiles of oral mucosal and patient-matched skin fibroblasts for multiple patients both prior to (0h) and (6h) following a wounding stimulus.

Differences in the gene expression profiles of oral mucosal and patient-matched skin fibroblasts were anlazyed for multiple patients both prior to (0h) and (6h) following a wounding stimulus. Serum starvation and subsequent stimulation provides a model for wounding and RNA extracted at 0h and 6h following this stimulus was hybridized to Affymetrix microarrays for analysis. We sought to compare the expression profiles both between oral and normal fibroblasts, in both serum depleted and stimulated conditions and also compare differences between patients.

Project description:<p><strong>INTRODUCTION:</strong> A decline in mitochondrial function represents a key factor of a large number of inborn errors of metabolism, which lead to an extremely heterogeneous group of disorders.</p><p><strong>OBJECTIVES:</strong> To gain insight into the biochemical consequences of mitochondrial dysfunction, we performed a metabolic profiling study in human skin fibroblasts using galactose stress medium, which forces cells to rely on mitochondrial metabolism.</p><p><strong>METHODS:</strong> Fibroblasts from controls, complex I and pyruvate dehydrogenase (PDH) deficient patients were grown under glucose or galactose culture condition. We investigated extracellular flux using Seahorse XF24 cell analyzer and assessed metabolome fingerprints using NMR spectroscopy.</p><p><strong>RESULTS:</strong> Incubation of fibroblasts in galactose leads to an increase in oxygen consumption and decrease in extracellular acidification rate, confirming adaptation to a more aerobic metabolism. NMR allowed rapid profiling of 41 intracellular metabolites and revealed clear separation of mitochondrial defects from controls under galactose using partial least squares discriminant analysis. We found changes in classical markers of mitochondrial metabolic dysfunction, as well as unexpected markers of amino acid and choline metabolism. PDH deficient cell lines showed distinct upregulation of glutaminolytic metabolism and accumulation of branched-chain amino acids, while complex I deficient cell lines were characterized by increased levels in choline metabolites under galactose.</p><p><strong>CONCLUSION:</strong> Our results show the relevance of selective culture methods in discriminating normal from metabolic deficient cells. The study indicates that untargeted fingerprinting NMR profiles provide physiological insight on metabolic adaptations and can be used to distinguish cellular metabolic adaptations in PDH and complex I deficient fibroblasts.</p>

Project description:The exposure of skin to ultraviolet (UV) radiation results in sunburn cell (SBC) and cyclobutane pyrimidine dimer (CPD) formation and local immune suppression. However, the pathways that regulate these events are poorly understood. Here, we exposed mice to UVB to study the early cytotoxic effects in absence of E3 ubiquitin protein ligase Cbl-b. We observed that Cbl-b-/- mice developed significantly less SBCs and CPDs compared to WT mice. In addition, microarray analysis revealed that loss of Cbl-b-induced cell tolerance genes rather than DNA repair genes. Taken together, our results suggest a novel role of Cbl-b in regulating UV cytotoxicity.
