SFRP2 modulates functional phenotype transition and energy metabolism of macrophages during diabetic wound healing [RAW264.7 cells]

Project description:Diabetic foot ulcer (DFU) is a serious complication of diabetes mellitus, which causes great health damage and economic burden to patients. The pathogenesis of DFU is not fully understood.We screened wound healing-related genes using bioinformatics analysis, and full-thickness skin injury mice model and cellular assays were used to explore the role of target genes in diabetic wound healing. SFRP2 was identified as a wound healing-related gene, and the expression of SFRP2 is associated with immune cell infiltration in DFU. In vivo study showed that suppression of SFRP2 delayed the wound healing process of diabetic mice, impeded angiogenesis and matrix remodeling, and increased macrophage infiltration in wound tissues. In addition, suppression of SFRP2 enhanced M1 polarization in both the early and later stage of wound healing, and decreased M2 polarization in the later stage, which impeded the transition of M1 to M2 polarization of wound healing. Moreover, suppression of SFRP2 affected the transcriptome signatures-related to inflammatory response and energy metabolism at the early stage of wound healing. Extracellular flux analysis (EFA) showed that suppression of SFRP2 decreased mitochondrial energy metabolism and increased glycolysis in injury-related macrophages. Furthermore, suppression of SFRP2 inhibited transcriptome signaturesrelated to carbohydrate metabolism, lipid metabolism and amino acid metabolism, which consists the three main components of energy metabolism of macrophages. In conclusions, SFRP2 may function as a wound healing-related gene in DFU, and suppression of SFRP2 impaired diabetic wound healing by compromising the M1-to-M2 transition of macrophages and modulating the balance between mitochondrial energy metabolism and glycolysis.

Metabolic Reprogramming and Reliance in Human Skin Wound Healing

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.

ANT2 accelerates cutaneous wound healing in aged skin by reverse senescence

Project description:An effective healing response is critical to healthy aging. Thus, the connection of regeneration and aging is needed to understand the complicated age-related healing process. Energy metabolism has been a common hallmark of both studies. In recent years, it become an emerging factor of skin homeostasis. Adenine nucleotide translocase-2 (ANT2) is a known cell proliferation marker and mediator of ATP import into mitochondria for energy homeostasis. Although energy homeostasis and the maintenance of mitochondrial function are critical for wound healing, the role of ANT2 in wound healing has not been elucidated. We found that ANT2 expression decreased during aging in mouse skin as well as during cellular senescence. Interestingly, overexpression of ANT2 in aged mouse skin promoted the healing of full-thickness cutaneous wounds. In addition, upregulation of ANT2 in replicative senescent human diploid dermal fibroblasts (HDFs) induced cell proliferation and migration, which are critical for the wound healing process. Furthermore, overexpression of ANT2 increased ATP production rate by activating the glycolysis pathway and also increased mitophagy, both of which are involved in energy homeostasis. Notably, ANT2-mediated upregulation of HSPA6 in aged HDFs inhibited the expression of pro-inflammatory genes that mediate cellular senescence and mitochondrial damage. This study demonstrates a new physiological role of ANT2 in skin wound healing via regulation of cell proliferation, energy homeostasis, and inflammation. Thus, our study links energy metabolism to skin homeostasis and identifies a genetic factor for improving wound healing with aging model.

MicroRNA array expression during normal urinary bladder wound healing

Project description:Urinary bladder wound healing is today pooorly chracterized. MicroRNAs are small non-coding RNA molecules with regulatory functions. In this study we aimed at identifying microRNAs expressed during bladder wound healing. We performed Affymetrix microRNA profiling of the rodent urinary bladder during healing of a surgically created wound.
