Project description:Wound healing is one fundamental physiological process which maintains the integrity of skin through a series of well-orchestrated biological and molecular events,effective resolution of inflammation is crucial for wound healing We used microarrays to characterize molecular mechanisms of wound healing with Spink7 KO mice of up-regulated genes during this process.
Project description:In order to determine molecular mechanisms of faster skin wound healing under decreasing FoxO1 protein expression, we performed microarray analysis on 3 days skin wounded samples from FoxO1+/- and WT mice. Skin wound-induced gene expression in WT and FoxO1+/- mice were measured on 3 days after injury. Three independent experiments were performed at each mouse.
Project description:Gene Expression in d5 wound-edge tissues of MFG-E8 WT and MFG-E8 KO mice Affymetrix GeneChip® Mouse Genome 430 array was used to study the gene expression in d5 wound-edge tissues of MFG-E8 WT and MFG-E8 KO mice Gene Expression in d5 wound-edge tissues of MFG-E8 WT and MFG-E8 KO mice

Project description:Wound healing is orchestrated by a spatial and temporal network of intercellular communication between epithelial cells, the stromal compartment, and the immune system. We found that Hgfac KO mice showed delayed wound healing in an endoscopic wound model. To dissect the celluar and molecular mechanisms of tissue healing, we collected tissues from day2 wounds or intact tissues from Hgfac WT and KO mice using a skin biopsy punch and dissociated cells for scRNA-seq analysis.
Project description:To investigate the effect of iNKT deficiency in the skin, the analysis of global gene expression in the skin tissues from WT and Cd1d KO mice were performed using RNA-seq data obtained from these samples.
Project description:The wounds were made on the back skin of Snhg26 knockout (KO) and wild type (WT) mice. The wound edge and skin tissue were collected and the epidermis were separated by incubate the tissue with dispaseII. Total RNA was extracted from the epidermis. The global transcriptome analysis of the epidermis were performed by using Affymetrix arrays.
Project description:Impaired skin wound healing is a significant global health issue, especially among the elderly. Wound healing is a well-orchestrated process involving the sequential phases of inflammation, proliferation, and tissue remodeling. Although wound healing is a highly dynamic and energy-requiring process, the role of metabolism remains largely unexplored. By combining transcriptomics and metabolomics of human skin biopsy samples, we mapped the core bioenergetic and metabolic changes in normal acute as well as chronic wounds in elderly subjects. We found upregulation of glycolysis, the tricarboxylic acid cycle, glutaminolysis, and β-oxidation in the later stages of acute wound healing and in chronic wounds. To ascertain the role of these metabolic pathways on wound healing, we targeted each pathway in a wound healing assay as well as in a human skin explant model using metabolic inhibitors and stimulants. Enhancement or inhibition of glycolysis and, to a lesser extent, glutaminolysis had a far greater impact on wound healing than similar manipulations of oxidative phosphorylation and fatty acid β-oxidation. These findings increase the understanding of wound metabolism and identify glycolysis and glutaminolysis as potential targets for therapeutic intervention.
