Targeting uPARAP Modifies Lymphatic Vessel Architecture and Attenuates Lymphedema. Circulation 2025; 151:1412-1429. [PMID: 40035133 PMCID: PMC12063686 DOI: 10.1161/circulationaha.124.072093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2024] [Accepted: 02/04/2025] [Indexed: 03/05/2025]
Abstract
BACKGROUND Lymphedema is an incurable disease associated with lymphatic dysfunction that causes tissue swelling and fibrosis. We investigated whether lymphedema could be attenuated by interfering with uPARAP (urokinase plasminogen activator receptor-associated protein; Mrc2 gene), an endocytic receptor involved in fibrosis and lymphangiogenesis. METHODS We generated mice with lymphatic endothelial cell (LEC)-specific uparap deficiency and compared them with constitutive knockout mice by applying a preclinical model of secondary lymphedema (SL). Computerized methods were applied for 2-dimensional and 3-dimensional image quantifications. Cellular effects of uPARAP deletion on lymphatic permeability were assessed by small interfering RNA-mediated silencing in human dermal LECs and a pharmacologic treatment targeting ROCK (Rho-associated coiled coil containing kinase), an established regulator of cell junctions. The uPARAP and vascular endothelial cadherin partnership was investigated through proximity ligation assay, coimmunoprecipitation, and immunostaining. An in silico model was generated to analyze the fluid-absorbing function of the lymphatic vasculature. To interfere with uPARAP, its downregulation was achieved in vivo through a gapmer approach. RESULTS uparap deficiency mitigated several key pathologic features of SL, including hindlimb swelling, epidermal thickening, and the accumulation and size of adipocytes. In both global and LEC-conditional uparap-deficient mice, induction of SL led to a distinctive labyrinthine vasculature, defined herein by twisted and hyperbranched vessels with overlapping cells. This topology, mainly composed of pre-collecting vessels, correlated with reduced SL, but not with change in fibrosis, highlighting the importance of uPARAP in regulating LEC functions in a lymphedematous context. In vitro, uPARAP knockdown in LECs impaired vascular endothelial growth factor C-mediated endosomal trafficking of vascular endothelial cadherin and induced overlapping cell junctions. The pharmacologic inhibition of ROCK recapitulated cell superimposition in vitro and the labyrinthine vasculature in vivo with attenuated SL. Computational modeling of labyrinthine lymphatic vasculature supported the observation on their improved fluid-absorbing function in comparison with a normal hierarchic network. These data provide proof of concept of inducing a labyrinthine topology to treat SL. For therapeutic purposes, we validated the use of an anti-uPARAP gapmer to induce a labyrinthine vasculature and attenuate SL formation. CONCLUSIONS Our findings provide evidence that downregulating uPARAP expression can induce a beneficial remodeling of lymphatic vasculature that attenuates lymphedema through a cell junction-based mechanism, offering a novel therapeutic pathway for lymphedema.

Abstract
Type IV collagen is a large triple helical molecule that forms a covalently cross-linked network within basement membranes (BMs). Type IV collagen networks play key roles in mechanically supporting tissues, shaping organs, filtering blood, and cell signaling. To ensure tissue health and function, all aspects of the type IV collagen life cycle must be carried out accurately. However, the large triple helical structure and complex life-cycle of type IV collagen, poses many challenges to cells and tissues. Type IV collagen predominantly forms heterotrimers and to ensure proper construction, expression of the distinct α-chains that comprise a heterotrimer needs tight regulation. The α-chains must also be accurately modified by several enzymes, some of which are specific to collagens, to build and stabilize the triple helical trimer. In addition, type IV collagen is exceptionally long (400nm) and thus the packaging and trafficking of the triple helical trimer from the ER to the Golgi must be modified to accommodate the large type IV collagen molecule. During ER-to-Golgi trafficking, as well as during secretion and transport in the extracellular space type IV collagen also associates with specific chaperone molecules that maintain the structure and solubility of collagen IV. Type IV collagen trimers are then delivered to BMs from local and distant sources where they are integrated into BMs by interactions with cell surface receptors and many diverse BM resident proteins. Within BMs type IV collagen self-associates into a network and is crosslinked by BM resident enzymes. Finally, homeostatic type IV collagen levels in BMs are maintained by poorly understood mechanisms involving proteolysis and endocytosis. Here, we provide an overview of the life cycle of collagen IV, highlighting unique mechanisms and poorly understood aspects of type IV collagen regulation.

Abstract
Retinal Müller glial cells (RMG) play a crucial role in retinal neuroinflammation, including autoimmune uveitis. Increasing evidence supports their function as active modulators of immune responses and potential atypical antigen-presenting cells (APCs). To further investigate this hypothesis, we conducted a differential proteome analysis of primary equine RMG from healthy controls and horses with equine recurrent uveitis (ERU), a spontaneous model of autoimmune uveitis. This analysis identified 310 proteins with differential abundance. Among these, the Major Histocompatibility Complex (MHC) class II and the enzyme Arginase 1 (ARG1) were significantly enriched in RMG from uveitis-affected horses, whereas Mannose Receptor C-type 2 (MRC2) and its interactor Thrombospondin 1 (THBS1) were more abundant in healthy RMG. The detection of MHC class II in equine RMG, consistent with previous studies, validates the robustness of our approach. Furthermore, the identification of ARG1 and MRC2, together with THBS1, provides new insights into the immunomodulatory and antigen-presenting properties of RMG. Immunohistochemical analyses confirmed the proteomic findings and revealed the spatial distribution of ARG1 and MRC2. ARG1 and MRC2 are thus markers for RMG in the neuroinflammatory or physiological milieu and highlight potential differences in the immune function of RMG, particularly in antigen presentation.

Abstract
BACKGROUND Orthodontic tooth movement (OTM) relies on the remodeling of periodontal tissues, including the periodontal ligament (PDL) and alveolar bone. Collagen remodeling plays a crucial role during this process, allowing for the necessary changes in the PDL's structure and function. Endo180, an urokinase plasminogen activator receptor-associated protein, is a transmembrane receptor regulated collagen remodeling. This study aims to investigate whether and how Endo180 participates in collagen remodeling within the PDL during OTM. MATERIALS AND METHODS A mechanical force-induced OTM rat model was established using a closed coiled spring to mesially move the right maxillary first molar. The distance of OTM was examined by micro-computed tomography (micro-CT). The collagen remodeling within the PDL was assessed using atomic force microscope (AFM), Hematoxylin-Eosin (HE) staining and Masson staining. Protein expressions of Endo180, collagen I (COL I) and collagen III (COL III) were analyzed via immunofluorescence staining. Additionally, the mRNA expressions of Endo180, COL I, and COL III in force-induced PDL cells were examined by RT-qPCR in vitro. To further illustrate the role of Endo180 in regulating COL I and COL III expressions, Endo180 siRNA (siEndo) was applied to force-stimulated PDL cells. RESULTS Force application increased OTM distance and disrupted collagen fiber organization, with a greater decrease in collagen elastic modulus on the mesial side than on the distal side of the PDL. After 7 days of force application, Endo180 and COL III expressions significantly increased in PDL tissues, while COL I expression decreased in PDL tissues. Compressive force loading in vitro upregulated the mRNA expressions of Endo180 and COL III, but downregulated COL I mRNA expression. Notably, Endo180 knockdown using siRNA suppressed force-induced COL III expression while restoring the downregulated COL I expression under compressive force stimuli. CONCLUSION Force-induced Endo180 expression modulates collagen remodeling in PDL during OTM by upregulating COL III and downregulating COL I. This collagen reorganization facilitates efficient tooth movement, highlighting Endo180 as a potential therapeutic target to optimize orthodontic treatment outcomes.

Abstract
Collagen is the most abundant protein in human and mammalian structures and is a component of the mammalian extracellular matrix (ECM). Recombinant collagen is a suitable alternative to native collagen extracted from animal tissue for various biomaterials. However, due to the limitations of the expression system, most recombinant collagens are collagen fragments and lack triple helix structures. In this study, Chinese hamster ovary (CHO) cells were used to express the full-length human type I collagen α1 chain (rhCol1α1). Moreover, Endo180 affinity chromatography and pepsin were used to purify pepsin-soluble rhCol1α1 (PSC1). The amino acid composition of PSC1 was closer to that of native human type I collagen, and PSC1 contained 9.1 % hydroxyproline. Analysis of the CD spectra and molecular weight distribution results revealed that PSC1 forms a stable triple helix structure that is resistant to pepsin hydrolysis and has some tolerance to MMP1, MMP2 and MMP8 hydrolysis. Atomic force microscopy (AFM), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) revealed that PSC1 can self-assemble into fibers at a concentration of 1 mg/ml; moreover, PSC1 can promote the proliferation and migration of NIH 3T3 cells. In conclusion, our data suggest that PSC1 is a highly similar type of recombinant collagen that may have applications in biomaterials and other medical fields.

Abstract
The extracellular matrix (ECM) is a complex, dynamic network of multiple macromolecules that serve as a crucial structural and physical scaffold for neighboring cells. In the tumor microenvironment (TME), ECM proteins play a significant role in mediating cellular communication between cancer-associated fibroblasts (CAFs) and tumor-associated macrophages (TAMs). Revealing the ECM modification of the TME necessitates the intricate signaling cascades that transpire among diverse cell populations and ECM proteins. The advent of single-cell sequencing has enabled the identification and refinement of specific cellular subpopulations, which has substantially enhanced our comprehension of the intricate milieu and given us a high-resolution perspective on the diversity of ECM proteins. However, it is essential to integrate single-cell data and establish a coherent framework. In this regard, we present a comprehensive review of the relationships among ECM, TAMs, and CAFs. This encompasses insights into the ECM proteins released by TAMs and CAFs, signaling integration in the TAM-ECM-CAF axis, and the potential applications and limitations of targeted therapies for CAFs. This review serves as a reliable resource for focused therapeutic strategies while highlighting the crucial role of ECM proteins as intermediates in the TME.

Abstract
The primary reason for high mortality rates among cancer patients is metastasis, where tumor cells migrate through the bloodstream from the original site to other parts of the body. Recent advancements in technology have significantly enhanced our comprehension of the mechanisms behind the bloodborne spread of circulating tumor cells (CTCs). One critical process, DNA methylation, regulates gene expression and chromosome stability, thus maintaining dynamic equilibrium in the body. Global hypomethylation and locus-specific hypermethylation are examples of changes in DNA methylation patterns that are pivotal to carcinogenesis. This comprehensive review first provides an overview of the various processes that contribute to the formation of CTCs, including epithelial-mesenchymal transition (EMT), immune surveillance, and colonization. We then conduct an in-depth analysis of how modifications in DNA methylation within CTCs impact each of these critical stages during CTC dissemination. Furthermore, we explored potential clinical implications of changes in DNA methylation in CTCs for patients with cancer. By understanding these epigenetic modifications, we can gain insights into the metastatic process and identify new biomarkers for early detection, prognosis, and targeted therapies. This review aims to bridge the gap between basic research and clinical application, highlighting the significance of DNA methylation in the context of cancer metastasis and offering new avenues for improving patient outcomes.

[PMID: 38897568 PMCID: PMC11301074 DOI: 10.1016/j.jbc.2024.107480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 05/17/2024] [Accepted: 05/30/2024] [Indexed: 06/21/2024] Open
Abstract
Phospholipase A2 receptor 1 (PLA2R1) is a 180-kDa transmembrane protein that plays a role in inflammation and cancer and is the major autoantigen in membranous nephropathy, a rare but severe autoimmune kidney disease. A soluble form of PLA2R1 has been detected in mouse and human serum. It is likely produced by proteolytic shedding of membrane-bound PLA2R1 but the mechanism is unknown. Here, we show that human PLA2R1 is cleaved by A Disintegrin And Metalloprotease 10 (ADAM10) and ADAM17 in HEK293 cells, mouse embryonic fibroblasts, and human podocytes. By combining site-directed mutagenesis and sequencing, we determined the exact cleavage site within the extracellular juxtamembrane stalk of human PLA2R1. Orthologs and paralogs of PLA2R1 are also shed. By using pharmacological inhibitors and genetic approaches with RNA interference and knock-out cellular models, we identified a major role of ADAM10 in the constitutive shedding of PLA2R1 and a dual role of ADAM10 and ADAM17 in the stimulated shedding. We did not observe evidence for cleavage by β- or γ-secretase, suggesting that PLA2R1 may not be a substrate for regulated intramembrane proteolysis. PLA2R1 shedding occurs constitutively and can be triggered by the calcium ionophore ionomycin, the protein kinase C activator PMA, cytokines, and lipopolysaccharides, in vitro and in vivo. Altogether, our results show that PLA2R1 is a novel substrate for ADAM10 and ADAM17, producing a soluble form that is increased in inflammatory conditions and likely exerts various functions in physiological and pathophysiological conditions including inflammation, cancer, and membranous nephropathy.

Abstract
Tumors are highly complex and heterogenous ecosystems where malignant cells interact with healthy cells and the surrounding extracellular matrix (ECM). Solid tumors contain large ECM deposits that can constitute up to 60% of the tumor mass. This supports the survival and growth of cancerous cells and plays a critical role in the response to immune therapy. There is untapped potential in targeting the ECM and cell-ECM interactions to improve existing immune therapy and explore novel therapeutic strategies. The most abundant proteins in the ECM are the collagen family. There are 28 different collagen subtypes that can undergo several post-translational modifications (PTMs), which alter both their structure and functionality. Here, we review current knowledge on tumor collagen composition and the consequences of collagen PTMs affecting receptor binding, cell migration and tumor stiffness. Furthermore, we discuss how these alterations impact tumor immune responses and how collagen could be targeted to treat cancer.

Ablation of integrin-mediated cell-collagen communication alleviates fibrosis. Ann Rheum Dis 2023; 82:1474-1486.

Abstract
OBJECTIVES Activation of fibroblasts is a hallmark of fibrotic processes. Besides cytokines and growth factors, fibroblasts are regulated by the extracellular matrix environment through receptors such as integrins, which transduce biochemical and mechanical signals enabling cells to mount appropriate responses according to biological demands. The aim of this work was to investigate the in vivo role of collagen-fibroblast interactions for regulating fibroblast functions and fibrosis. METHODS Triple knockout (tKO) mice with a combined ablation of integrins α1β1, α2β1 and α11β1 were created to address the significance of integrin-mediated cell-collagen communication. Properties of primary dermal fibroblasts lacking collagen-binding integrins were delineated in vitro. Response of the tKO mice skin to bleomycin induced fibrotic challenge was assessed. RESULTS Triple integrin-deficient mice develop normally, are transiently smaller and reveal mild alterations in mechanoresilience of the skin. Fibroblasts from these mice in culture show defects in cytoskeletal architecture, traction stress generation, matrix production and organisation. Ablation of the three integrins leads to increased levels of discoidin domain receptor 2, an alternative receptor recognising collagens in vivo and in vitro. However, this overexpression fails to compensate adhesion and spreading defects on collagen substrates in vitro. Mice lacking collagen-binding integrins show a severely attenuated fibrotic response with impaired mechanotransduction, reduced collagen production and matrix organisation. CONCLUSIONS The data provide evidence for a crucial role of collagen-binding integrins in fibroblast force generation and differentiation in vitro and for matrix deposition and tissue remodelling in vivo. Targeting fibroblast-collagen interactions might represent a promising therapeutic approach to regulate connective tissue deposition in fibrotic diseases.

Abstract
Polysaccharides, the most diverse forms of organic molecules in nature, exhibit a large number of different biological activities, such as immunomodulatory, radioprotective, antioxidant, regenerative, metabolic, signaling, antitumor, and anticoagulant. The reaction of cells to a polysaccharide is determined by its specific interaction with receptors present on the cell surface, the type of cells, and their condition. The effect of many polysaccharides depends non-linearly on their concentration. The same polysaccharide in different conditions can have very different effects on cells and organisms, up to the opposite; therefore, when conducting studies of the biological activity of polysaccharides, both for the purpose of developing new drugs or approaches to the treatment of patients, and in order to clarify the features of intracellular processes, information about already known research results is needed. There is a lot of scattered data on the biological activities of polysaccharides, but there are few reviews that would consider natural polysaccharides from various sources and possible molecular mechanisms of their action. The purpose of this review is to present the main results published at different times in order to facilitate the search for information necessary for conducting relevant studies.

Abstract
The continuous remodeling of the tumor microenvironment (TME) during prostate tumorigenesis is emerging as a critical event that facilitates cancer growth, progression and drug-resistance. Recent advances have identified extensive communication networks that enable tumor-stroma cross-talk, and emphasized the functional importance of diverse, heterogeneous stromal fibroblast populations during malignant growth. Cancer-associated fibroblasts (CAFs) are a vital component of the TME, which mediate key oncogenic events including angiogenesis, immunosuppression, metastatic progression and therapeutic resistance, thus presenting an attractive therapeutic target. Nevertheless, how fibroblast heterogeneity, recruitment, cell-of-origin and differential functions contribute to prostate cancer remains to be fully delineated. Developing our molecular understanding of these processes is fundamental to developing new therapies and biomarkers that can ultimately improve clinical outcomes. In this review, we explore the current challenges surrounding fibroblast identification, discuss new mechanistic insights into fibroblast functions during normal prostate tissue homeostasis and tumorigenesis, and illustrate the diverse nature of fibroblast recruitment and CAF generation. We also highlight the promise of CAF-targeted therapies for the treatment of prostate cancer.
