Wound healing pathologies are an increasing problem in ageing societies. Chronic, non-healing wounds, which cause high morbidity and severely reduce the quality of life of affected individuals, are frequently observed in aged individuals and people suffering from diseases affected by the Western lifestyle, such as diabetes. Causal treatments that support proper wound healing are still scarce. Here, we performed expression proteomics to study the effects of the small molecule TOP-N53 on primary h ...[more]

Project description:Wound healing pathologies are an increasing problem in ageing societies. Chronic, non-healing wounds, which cause high morbidity and severely reduce the quality of life of affected individuals, are frequently observed in aged individuals and people suffering from diseases affected by the Western lifestyle, such as diabetes. Causal treatments that support proper wound healing are still scarce. Here, we performed expression proteomics to study the effects of the small molecule TOP-N53 on primary human skin fibroblasts and keratinocytes. TOP-N53 is a dual-acting nitric oxide donor and phosphodiesterase-5 inhibitor increasing cGMP levels to support proper wound healing. In contrast to keratinocytes, which did not exhibit global proteome alterations, TOP-N53 had profound effects on the proteome of skin fibroblasts. In fibroblasts, TOP-N53 activated the cytoprotective, lysosomal degradation pathway autophagy and induced the expression of the selective autophagy receptor p62/SQSTM1. Thus, activation of autophagy might in part be responsible for beneficial effects of TOP-N53.

Expression data from human 3D skin models in response to IL-31 treatment

Project description:Atopic dermatitis, a chronic inflammatory skin disease with increasing prevalance, is closely associated with skin barrier defects. A cytokine related to disease severity and inhibition of keratinocyte differentiation is IL-31. To identify its molecular targets, IL-31-dependent gene expression was determined in 3-dimensional organotypic skin models. In this data set we include expression data from human 3D skin models treated with or without IL-31 for 2, 8, 24 and 48 hours. As a source of keratinocytes HaCaT cells were used. These are immortalized primary keratinocytes. Human dermal fibroblasts were derived from a skin biopsy. A total of 8 samples were analyzed. We compared the control vs the IL-31 treated sample for each time point.

Single-cell analysis of human dermal fibroblasts isolated from a single male donor over 35 years

Project description:Background: Skin homeostasis is mediated by dermal fibroblasts and is affected by aging. Although age-related heterogeneity in fibroblasts has been reported, the effects of donor and species on this heterogeneity are unclear. Methods: To analyze age-related transcriptomic changes in human dermal fibroblasts, single-cell RNA sequencing was performed on dermal fibroblasts (ASF-4 cells) collected from the inner forearm of a volunteer over three decades. Results: Four main cell subpopulations changed with donor age and showed proliferative, homeostasis, fibrotic, and senescence functional annotations. The downregulation of the expression of genes encoding key extracellular matrix production and mechanotransduction components decreased with donor age. Interestingly, dermal fibroblasts have two putative differentiation pathways: one that involves the acquisition of senescent properties and the acquisition of fibrotic properties without the suppression of proliferation. Aging induced fibroblast differentiation in a manner involving the acquisition of senescent properties. Conclusion:Reconciling the various aspects of fibroblast heterogeneity may provide insight into the mechanisms underlying human skin aging and associated phenomena, including wrinkles, sagging, delayed wound healing, and suppressed scar formation.

X-chromosome inactivation in monkey embryos and pluripotent stem cells

Project description:In this study, we explored x-inactivation in monkey embryos (ICM and TE separately) and pluripotent stem cells (IVF derived ES, SCNT-derived ES and monkey iPS) To elucidate x-inactivation in experimentally reprogrammed pluripotent cells, we derived pluripotent stem cells by both SCNT and iPS approaches from same parental skin fibroblasts. We also compared gene patterns of those cells to IVF-derived counterpart. The transcriptomes of rhesus monkey embryonic stem cell lines derived by both SCNT (CRES) and iPS (RiPS) from same monkey skin fibroblasts were compared each other. Both experimentally reprogrammed cells were also compared with IVF-derived counterpart (ORMES23). Finally, the adult somatic skin fibroblasts were analyzed. Three biological replicates of each cell line (A, B, C) were analyzed.

Skin regeneration is enabled in the absence of fibroblast inflammatory priming

Project description:Mammalian skin wounds heal by forming fibrotic scars. We report that reindeer antler velvet exhibits regenerative wound healing, whereas identical injury to back skin forms scar. This regenerative capacity was retained following ectopic transplantation of velvet to scar-forming sites. Single-cell mRNA/ATAC-Sequencing revealed that while uninjured velvet fibroblasts resembled human fetal fibroblasts, back skin fibroblasts were enriched in pro-inflammatory features resembling adult human fibroblasts. Injury elicited site-specific immune polarization; back skin fibroblasts amplified the immune response, whereas velvet fibroblasts adopted an immunosuppressive state leading to restrained myeloid maturation and hastened immune resolution ultimately enabling myofibroblast reversion to a regeneration-competent state. Finally, regeneration was blunted following application of back skin associated immunostimulatory signals or inhibition of pro-regenerative factors secreted exclusive to velvet fibroblasts. This study highlights a unique model to interrogate mechanisms underlying divergent healing outcomes and nominates both decoupling of stromal-immune crosstalk and reinforcement of pro-regenerative fibroblast programs to mitigate scar.

Expression profiling of skin fibroblast and iPSC from Werner Syndrome

Project description:The premature aging disorder Werner Syndrome (WS) is characterized by early onset of aging phenotypes resembling natural aging. In most WS patients there are mutations in the DNA helicase WRN, an enzyme important in maintaining genome stability and telomere replication. Interestingly, its clinical manifestations reflect a severe degree of deterioration for connective tissue, whereas the central nervous system is less affected. We suggest that the varied vulnerability to aging is regulated by an unknown mechanism that protects specific lineages of stem cells from premature senescence. To address this problem, we reprogrammed patient skin fibroblasts to induced pluripotent stem cells (iPSC). The expression profile for the differentiated normal and WS fibroblasts and undifferentiated iPSC were compared. A distinct expression profile was found between normal and WS fibroblasts, however, few changes of gene expression were found in iPSC. Our findings suggest an erasure of aging phenotype associated with WS in reprogrammed iPSC. Human normal and WS skin fibroblasts were reprogrammed to induced pluripotent stem cells (iPSC). These samples, before and after reprogramming, were analyzed for the change of gene expression profile.

Phosphodiesterase 9A controls nitric-oxide-independent cGMP and hypertrophic heart disease.

Project description:Cyclic guanosine monophosphate (cGMP) is a second messenger molecule that transduces nitric-oxide- and natriuretic-peptide-coupled signalling, stimulating phosphorylation changes by protein kinase G. Enhancing cGMP synthesis or blocking its degradation by phosphodiesterase type 5A (PDE5A) protects against cardiovascular disease. However, cGMP stimulation alone is limited by counter-adaptions including PDE upregulation. Furthermore, although PDE5A regulates nitric-oxide-generated cGMP, nitric oxide signalling is often depressed by heart disease. PDEs controlling natriuretic-peptide-coupled cGMP remain uncertain. Here we show that cGMP-selective PDE9A (refs 7, 8) is expressed in the mammalian heart, including humans, and is upregulated by hypertrophy and cardiac failure. PDE9A regulates natriuretic-peptide- rather than nitric-oxide-stimulated cGMP in heart myocytes and muscle, and its genetic or selective pharmacological inhibition protects against pathological responses to neurohormones, and sustained pressure-overload stress. PDE9A inhibition reverses pre-established heart disease independent of nitric oxide synthase (NOS) activity, whereas PDE5A inhibition requires active NOS. Transcription factor activation and phosphoproteome analyses of myocytes with each PDE selectively inhibited reveals substantial differential targeting, with phosphorylation changes from PDE5A inhibition being more sensitive to NOS activation. Thus, unlike PDE5A, PDE9A can regulate cGMP signalling independent of the nitric oxide pathway, and its role in stress-induced heart disease suggests potential as a therapeutic target.
