They share a characteristic structure composed of a core protein with two or more heparan sulfate chains and a glycosyl-phosphatidylinositol anchor that attaches them to the cell membrane. Aberrant expression of certain glypicans such as GPC1, GPC2, and GPC3 has been found in multiple types of cancer and causes the dysregulation of Wnt, hedgehog, and other signaling pathways, making them emerging targets for cancer immunotherapy. The molecular mechanism by which glypicans interact with signaling factors will provide insights for the development of cancer therapeutics. However, the structural complexes of human glypicans with Wnt and other key signaling factors remain unsolved. In this brief review, we analyze the current protein structural evidence for glypicans, with an emphasis on their interaction with Wnt, in an effort to provide insights to understand the molecular mechanisms by which glypicans play positive or negative roles in Wnt signaling in cancer and to discuss their translational potentials.","PeriodicalId":74585,"journal":{"name":"Proteoglycan research","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12101617/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144144839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On their native basement membrane capsule the injured lens epithelium undergoes regenerative repair, with the wound closing within a few days. Their migration across the wound area is led by a population of activated lens resident immune cells. The same leader cell population also directs the wounded epithelium to migrate off the outside edges of the lens explant across the surrounding tissue culture dish, where a pro-fibrotic matrix microenvironment is produced that signals the resident immune cells at the leading edge to acquire a myofibroblast phenotype. We separated the wounded lens explants from those cells on the surrounding culture substrate at different times points over three days post wounding and performed an unbiased RNAseq analysis to identify the changes in proteoglycan expression from time 0 in the environment in which regenerative repair takes place and compared those results to the impact on proteoglycan expression when the same cell populations encountered the microenvironment where fibrosis is induced. In both environments there were changes in expression of proteoglycans associated with promoting cell migration. However, the greatest changes in proteoglycan expression occurred in the fibrosis-inducing environment, which included a subset of SLRPs with known functions in signaling the activation of TGFβ and in mediating collagen fibrillogenesis. The RNAseq results also revealed that in the pro-fibrotic microenvironment there is an induction of cell surface proteoglycans that are associated with mechanotransduction signaling events linked to their role in the assembly of integrin focal adhesion contacts.","PeriodicalId":74585,"journal":{"name":"Proteoglycan research","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12890184/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146168379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the rat Stab2/HARE has a high degree homology to mouse Stab2/HARE which has been cloned, our hypothesis is that the rat receptor is identical to mouse and very similar to the human receptor. Rat Stab2/HARE was cloned and expressed in the FlpIn HEK293 cell line. The recombinant protein was analyzed for HA and heparin binding/endocytosis as well as synthetic heparin (Dekaparin) in a mouse knockout model. The secreted ecto-domain was also created for surface plasmon resonance analysis. The physical structure of rat Stab2/HARE is different than human in that the small isoform is not expressed as robustly and reduction of the protein results in what is likely two physical conformational forms. Rat Stab2/HARE binding strength with HA is weaker when compared to human Stab2/HARE, but rate of endocytosis is higher. Heparin-Stab2/HARE bonding strength is similar to human, though endocytic rate tends to be higher. Metabolism of Dekaprin is delayed in a Stab2KO mouse model and affects liver sequestration of this drug. Rat Stab2/HARE has similar properties as the human Stab2/HARE with the exceptions that the rat recombinant protein has a different physical structure and has an increased HA and heparin internalization rate.","PeriodicalId":74585,"journal":{"name":"Proteoglycan research","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12393792/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144981871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proteoglycans, multifaceted molecules within the tumor microenvironment, have garnered attention due to their diverse roles in cancer progression. Their unique ability to interact with specific membrane receptors, growth factors, and cytokines provides a promising avenue for the development of recombinant proteoglycan-based therapies that could enhance the precision and efficacy of cancer treatment. In this study, we performed a comprehensive analysis of the proteoglycan gene landscape in human breast carcinomas. Leveraging the available wealth of genomic and clinical data regarding gene expression in breast carcinoma and using a machine learning model, we identified a unique gene expression signature composed of five proteoglycans differentially modulated in the tumor tissue: Syndecan-1 and asporin (upregulated) and decorin, PRELP and podocan (downregulated). Additional query of the breast carcinoma data revealed that serglycin, previously shown to be increased in breast carcinoma patients and mouse models and to correlate with a poor prognosis, was indeed decreased in the vast majority of breast cancer patients and its levels inversely correlated with tumor progression and invasion. This proteoglycan gene signature could provide novel diagnostic capabilities in breast cancer biology and highlights the need for further utilization of publicly available datasets for the clinical validation of preclinical experimental results.","PeriodicalId":74585,"journal":{"name":"Proteoglycan research","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11893098/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143598200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three HAS classes have been identified with biotechnological utility, but only the Class II PmHAS from Pasteurella multocida Type A has been useful for preparation of very defined HA polymers in vitro. Two general chemoenzymatic strategies with different size products are possible: (1) repetitive step-wise extension reactions by sequential addition of a single monosaccharide from a donor UDP-sugar onto an acceptor (or \"primer\") comprised of a short glycosaminoglycan chain (e.g., HA di-, tri- or tetrasaccharide) or an artificial glucuronide yielding homogeneous oligosaccharides in the range of 2 to ~20 monosaccharide units (n = 1 to ~10), or (2) \"one-pot\" polymerization reactions employing acceptor-mediated synchronization with stoichiometric size control yielding quasi-monodisperse (i.e., polydispersity approaching 1; very narrow size distributions) polysaccharides in the range of ~7 kDa to ~2 MDa (n = ~17 to 5000). In either strategy, acceptors containing non-carbohydrate functionalities (e.g., biotin, fluorophores, amines) can add useful moieties to the reducing termini of HA chains at 100% efficiency. As a further structural diversification, PmHAS can utilize a variety of unnatural UDP-sugar analogs thus adding novel groups (e.g., trifluoroacetyl, alkyne, azide, sulfhydryl) along the HA backbone and/or at its nonreducing terminus. This review discusses the current understanding and recent advances in HA chemoenzymatic synthesis methods using PmHAS. This powerful toolbox has potential for creation of a multitude of HA-based probes, therapeutics, drug conjugates, coatings, and biomaterials.","PeriodicalId":74585,"journal":{"name":"Proteoglycan research","volume":"2 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11673988/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142904164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we report a large-scale tumor-associated GPC3 co-immunoprecipitation (CoIP)-proteomic study using liver cancer xenograft tumors in mice. We identified 153 GPC3-associated proteins through mass spectrometry. To identify potential drug targets, we categorized GPC3-associated proteins based on their subcellular locations using UniProt annotations, with a focus on extracellular proteins. Additionally, we annotated differentially expressed proteins in hepatocellular carcinoma (HCC) versus non-tumor liver samples based on the literature, analyzed expression levels in tumor versus normal tissues using TCGA and GTEx databases via GEPIA, and identified prognostic liver cancer markers according to GEPIA. Among GPC3-associated proteins, Immunoglobulin Superfamily Member 1 (IGSF1), alpha-fetoprotein (AFP), FAT Atypical Cadherin 1 (FAT1), Formin 1 (FMN1), and Guanylate Cyclase 2C (GUCY2C), were identified as potential therapeutic targets. Furthermore, we validated the direct protein interaction between GPC3 and AFP through immunoprecipitation with purified proteins and through co-localization imaging using immunofluorescence microscopy. This study provides large proteomic datasets related to GPC3-associated proteins, enhancing our understanding of glypican biology in cancer cells and offering a new approach to identifying immunotherapy targets.","PeriodicalId":74585,"journal":{"name":"Proteoglycan research","volume":"2 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11737099/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143018015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
