Project description:Acute compartment syndrome (ACS) is a disease in which local circulation is affected due to increased pressure within the compartment. We previously found in patients with calf fractures, the pressure of fascial compartment could be sharply reduced upon the appearance of tension blisters. Deep fascia, as the important structure for compartment, might play key role in this process. Therefore, the aim of the present study was to examine the differences in gene profile in deep fascia tissue in fracture patients of the calf with or without tension blisters, and to explore the role of fascia in pressure improvement in ACS. Patients with lower leg fracture were enrolled and divided into without tension blister control group (CON group, n=10), and with tension blister group (TB group, n=10). Deep fascia tissues were collected and LC-MS/MS label-free quantitative proteomics were performed. Genes involved in fascia structure and fibroblast function were further validated by Western blot. The differentially expressed proteins were found to be mainly enriched in pathways related to protein synthesis and processing, stress fiber assembly, cell-substrate adhesion, leukocyte mediated cytotoxicity, and cellular response to stress. Compared with the CON group, the expression of Peroxidasin homolog (PXDN), which promotes the function of fibroblasts, and Leukocyte differentiation antigen 74 (CD74), which enhances the proliferation of fibroblasts, were significantly upregulated, while the expression of Matrix metalloproteinase-9 (MMP9), which is involved in collagen hydrolysis, and Neutrophil elastase (ELANE), which is involved in elastin hydrolysis, were significantly reduced in the TB group (p all <0.05), indicating fascia tissue underwent microenvironment reconstruction during ACS.In summary, the ACS accompanied by blisters is associated with the enhanced function and proliferation of fibroblasts and reduced hydrolysis of collagen and elastin. The adaptive alterations in the stiffness and elasticity of the deep fascia might be crucial for pressure release of ACS.

Project description:Fibrosis is a common and integral pathological feature in various chronic diseases, capable of affecting any tissue or organ. Fibrosis within deep fascia is implicated in many myofascial disorders, including gluteal muscle contracture (GMC), Dupuytren’s disease, plantar fasciitis, iliotibial band syndrome, and chronic muscle pain. In this study, we performed scRNA seq analysis on fibrotic fascia associated with GMC and compared them to nonfibrotic control fascial samples. Our findings show that fibroblast and macrophage cells play a role in pathological tissue remodeling within fibrotic deep fascia. We observed an upregulation of various collagens, proteoglycans, and extracellular matrix (ECM) glycoproteins in contracture deep fascia, attributed to the widespread activation of fibroblast subclusters. Additionally, two pro fibrotic macrophage subpopulations, SPP1+ MP and ECM like MP, appear to facilitate ECM deposition in fibrotic deep fascia by either regulating fibroblast activation or directly contributing to ECM production. SPP1+ MP and ECM like MP cells, as well as the signal interaction between SPP1+ MP and fibroblast cells, present novel and potential therapeutic target for treating GMC and other related myofascial disorders.

Project description:Patients with a history of recurrent ventral hernias (n=10) were compared with a control group (n=8) using high-throughput microarrays. Skin and fascia samples (taken away from the site of the ventral hernia) were analyzed from both groups. Our experiments show distinct genetic profiles between the skin and fascia of recurrent ventral hernia patients as compared to controls. There were also a great number of statistically significant genes in the skin as compared to the fascia. The functions of the genes in the skin were diverse and included wound healing, transcription regulation, and immunology. The genes in the fascia, however, were more specific concentrating primarily on immunology, regulation of gene expression and cellular metabolism, and development. Total RNA extracted from skin and fascia of patients with a history of recurrent ventral hernias and a control group. There were no replicates for the same source material for the same patient.

Project description:The objective of this study was to analyze gene expression associated to extracellular matrix components of normal palmar fascia and tissues affected by Dupuytren's disease. We used microarrays to detail the global programme of gene expression associated to Dupuytren's disease. Total RNA was isolated from three different samples corresponding to two different individuals with Dupuytren's disease: Dupuytren's diseased contracture cords (DDC), palmar fascia clinically unaffected by Dupuytren's disease contracture (NPF), and normal forehand fascia (NFF).

Project description:Dupuytren's disease (DD) is characterized by nodular fibroblastic proliferation of the palmar fascia leading to contracture of the hand. We performed a cDNA microarray analysis of DD palmar cord tissue. Normal-appearing palmar fascia adjacent to the diseased cord from the same patient and palmar fascia from patients undergoing carpal tunnel release were used as controls. A type II microarray experiment was used on amplified sample RNA. Samples were hybridized to arrays containing 42,000 gene elements. Array data was analyzed with the on-line software from the Stanford Microarray Database.

Project description:PURPOSE: Dupuytren's disease (DD) is characterized by fibroblastic proliferation of the palmar fascia, often leading to flexion contracture in the hand. Although there is a strong genetic component the genome-wide expression of novel genes is not known. The purpose of this study was to use DNA microarray technology to identify upregulated genes in DD. METHODS: Human tissue samples were harvested from 3 patient sources: DD cord tissue (n = 20), normal-appearing adjacent control fascia (n = 15), and palmar fascia from patients having carpal tunnel release (n = 15). DNA microarray analysis was performed on amplified sample RNA. Novel genes were compared with known gene functions. A candidate gene of interest was studied further by using immunohistochemistry on DD tissue samples and controls. : Several novel genes not described previously in the study of DD were upregulated significantly, including MafB, collagen type V, alpha-2 (COL5A2), collagen type VIII, alpha-1 (COL8A1), contactin I (CNTN1), and leucine-rich repeat containing 17 (LRRC17). These upregulated genes were compared with their known gene-expression profiles in other tissues and their purported functions. MafB was found to be of particular interest because of its prominent role in tissue development and cellular differentiation. MafB immunohistochemistry showed positive staining in 50% of the DD specimens but complete absence of MafB in all control tissues (adjacent control fascia, carpal tunnel fascia). Co-localization experiments with MafB and alpha-smooth muscle actin showed staining properties in similar regions but these 2 proteins were not confined solely to the same cells. CONCLUSIONS: Microarray analysis of DD tissue has identified significant upregulated gene expression of MafB. MafB protein also is found in Dupuytren's cords but not in control fascia. Co-localization data suggest that the association of MafB with DD is not related exclusively to myofibroblast proliferation. Because of its role in fibroblastic transformation in other models MafB and its relationship to the pathogenesis of DD deserves further study.
