Exploring the role of osteoglycin in type 2 diabetes: implications for insulin resistance and vascular pathophysiology. Am J Physiol Endocrinol Metab 2023; 325:E649-E660. [PMID: 37819194 PMCID: PMC10874653 DOI: 10.1152/ajpendo.00320.2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Accepted: 10/05/2023] [Indexed: 10/13/2023]
Abstract
Osteoglycin, a fundamental proteoglycan within the vascular extracellular matrix, is expressed in vascular smooth muscle cells (VSMCs). Type 2 diabetes (T2D) is associated with cardiovascular disease (CVD) but the role of osteoglycin in the development of CVD is controversial to date. Therefore, our aims are to determine and compare the level of osteoglycin in T2D patients with/without CVD versus control subjects both at serum and vascular tissue and to analyze in vitro role of osteoglycin in VSMCs under calcified conditions. For this, serum osteoglycin levels were determined by enzyme-linked immunosorbent assay (ELISA) in 117 controls and 129 patients with T2D (46 with CVD and 83 without CVD), revealing a significant increase in patients with T2D compared with controls. Osteoglycin level was not an estimator of CVD but correlated with markers of insulin resistance (triglycerides and triglycerides/high-density lipoprotein cholesterol index) in patients with T2D. At the vascular level, osteoglycin expression was assessed by RT-qPCR and immunohistochemistry, and no significant differences were observed between calcified arteries from patients with T2D and noncalcified arteries from controls. In vitro experiments using VSMCs (mock and overexpressing osteoglycin) under calcifying conditions were performed to analyze the osteoglycin function. The overexpression of osteoglycin in VMSCs under calcifying conditions revealed an increase of cell proliferation without effect on apoptosis and an upregulation of the expression of autotaxin (ATX) involved in inflammatory processes. In conclusion, osteoglycin could play a role in glycemic homeostasis, being a potential biomarker of insulin resistance in patients with T2D. Furthermore, osteoglycin could indirectly participate in the development of atherosclerosis through its regulatory effect on ATX and by proliferating VSMCs.NEW & NOTEWORTHY This study uncovers an increase of serum osteoglycin levels in patients with type 2 diabetes, which does not appear to be associated with the development of atherosclerosis, but rather with insulin resistance in this population. Overexpression of osteoglycin increased proliferation and upregulated the expression of autotaxin in vascular smooth muscle cells within calcified environments. Osteoglycin could be a biomarker of insulin resistance for type 2 diabetes and could be indirectly involved in the development of atherosclerosis.

Osteoglycin as a Potential Biomarker of Mild Kidney Function Impairment in Type 2 Diabetes Patients. J Clin Med 2021; 10:jcm10102209. [PMID: 34065223 PMCID: PMC8161135 DOI: 10.3390/jcm10102209] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 04/26/2021] [Accepted: 05/18/2021] [Indexed: 01/09/2023] Open
Abstract
Osteoglycin (OGN) could be a biomarker of mild kidney function impairment in type 2 diabetes (T2D). Our study aimed to determine the association between serum OGN and impaired kidney function risk in T2D patients and to analyze its potential role as an estimator of kidney disturbances in this population. This cross-sectional study included 147 T2D patients (65 ± 8 years, 58.5% males), and 75 healthy controls (63 ± 10 years, 36% males). Circulating OGN levels were determined by ELISA. Linear regression modeling was performed to determine the variables influencing circulating OGN, and an ROC curve was plotted to assess the usefulness of OGN as an estimator of diabetic kidney disease risk. Circulating OGN was significantly increased in T2D patients compared to controls (18.41 (14.45–23.27) ng/mL vs. 8.74 (7.03–12.35) ng/mL; p < 0.001). We found a progressive increase in serum OGN according to the severity of kidney impairment in T2D patients (normal kidney function: 16.14 (12.13–20.48) ng/mL; mildly impaired kidney function: 19.15 (15.78–25.90) ng/mL; moderate impaired kidney function: 21.80 (15.06–29.22) ng/mL; p = 0.006). Circulating OGN was an independent estimator of mildly impaired kidney function risk in T2D patients. We suggest that serum OGN could act as an albuminuria-independent biomarker of incipient kidney dysfunction in T2D patients.

Abstract
Osteoglycin (Ogn), a class III SLRP member with multiple glycosylation sites, has been proposed to be engaged in cardiac dysfunction and adverse remodeling in human heart failure following myocardial infarction. However, the underlying mechanism remains to be elucidated. Thus, we sought to define the role of Ogn in regulation of the Wnt pathway on myocardial fibrosis and epithelial/endothelial-mesenchymal transformation (EMT/EndMT) in mice with myocarditis. The pathological changes are observed, while hematoxylin-eosin staining and picric acid Sirius red staining were conducted in successfully constructed myocarditis mouse models. Immunohistochemistry and enzyme-linked immunosorbent assay were adopted to determine Ogn and β-catenin levels and serum procollagen propeptide concentrations in the mouse myocardial tissues, respectively. Expression of Ogn and Wnt signaling pathway-related factors were measured by reverse transcription quantitative polymerase chain reaction and western blot assay, cell viability by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, and cell cycle distribution and apoptosis by flow cytometry. We saw indicative pathological changes accompanied by many Ogn and β-catenin positive cells and increased serum procollagen propeptide, in the mouse myocardial tissues. Loss function assays showed reduced levels of Ogn, β-catenin, LRP6, TGF-β1, Twist, FSP-1, α-SMA and higher levels of E-cadherin and VE-cadherin, together with decreased proliferation rate, as well as increased apoptosis rate, indicating that the Wnt signaling pathway, proliferation were inhibited while apoptosis was enhanced with upon gene silencing. Coherently, depletion of Ogn inhibits myocardial fibroblasts proliferation and EMT/EndMT while facilitating myocardial fibroblasts apoptosis in myocarditis through the Wnt signaling pathway, thus serving as an intervention target for the molecular treatment of myocarditis.

Abstract
Interstitial lung disease (ILD) comprises of a group of diffuse parenchymal lung disorders that are strongly associated with substantial morbidity and mortality. Previous studies have highlighted the therapeutic significance of microRNAs (miRNAs) in the treatment of ILD. Thus this study aims to investigate the mechanism by which miR-140 affects ILD through the regulation of osteoglycin (OGN)-Wnt signaling pathway. Gene expression microarray analysis was performed to screen ILD-related differentially expressed genes and miRNAs that regulated OGN. The targeting relationship between miR-140 and OGN was verified. Ectopic expression and knockdown experiments were performed in lung fibroblasts to explore the potential mechanism of action of miR-140 in ILD. The expression of miR-140, OGN, as well as Wnt- and pulmonary fibrosis-related factors, was determined by RT-qPCR and Western blot analysis. In addition, cell viability and apoptosis were examined. OGN was found to be negatively regulated by miR-140. The ectopic expression of miR-140 and OGN silencing resulted in increased lung fibroblast apoptosis and Wnt3a expression, along with reduced proliferation and pulmonary fibrosis. Our results also revealed that miR-140 decreased OGN, thereby activating the Wnt signaling pathway, which was observed to further affect the expression of genes associated with the progression of pulmonary fibrosis in mouse fibroblasts. In conclusion, the key findings from our study suggest that overexpressed miR-140 suppresses ILD development via the Wnt signaling pathway by downregulating OGN, which could potentially be used as a therapeutic target for ILD.

Abstract
Cardiovascular disease (CVD) is the most common cause of death in industrialized countries. One underlying cause is atherosclerosis, which is a systemic disease characterized by plaques of retained lipids, inflammatory cells, apoptotic cells, calcium and extracellular matrix (ECM) proteins in the arterial wall. The biologic composition of an atherosclerotic plaque determines whether the plaque is more or less vulnerable, that is prone to rupture or erosion. Here, the ECM and tissue repair play an important role in plaque stability, vulnerability and progression. This review will focus on ECM remodelling in atherosclerotic plaques, with focus on how ECM biomarkers might predict plaque vulnerability and outcome.

Abstract
Aim: Osteoglycin is one of proteoglycans that are biologically active components of vascular extracellular matrix. However, the role of osteoglycin in atherosclerosis remains unclear. Methods: We investigated plasma osteoglycin levels and the presence, severity, and lesion morphology of coronary artery disease (CAD) in 462 patients undergoing elective coronary angiography. Results: Of 462 patients, 245 had CAD. Osteoglycin levels were higher in patients with CAD than without CAD (median 29.7 vs. 25.0 ng/mL, P < 0.05). However, osteoglycin levels did not differ among patients with one-vessel, two-vessel, or three-vessel disease (30.8, 30.6, and 29.4 ng/mL, respectively) and did not correlate with the number of stenotic segments. Among 245 CAD patients, 41 had complex coronary lesions, and 70 had total occlusion, of whom 67 had good collateralization. Between 70 patients with occlusion and 175 without occlusion, osteoglycin levels did not differ (30.4 vs. 29.5 ng/mL). Notably, osteoglycin levels were lower in 41 patients with complex lesions than in 204 without such lesions (24.2 vs. 31.6 ng/mL, P < 0.02). In multivariate analysis, osteoglycin levels were an independent factor for complex lesion but not for CAD. Odds ratio for complex lesion was 0.80 (95%CI = 0.67–0.96) for each 10 ng/mL increase in osteoglycin levels (P < 0.02). Conclusion: Although plasma osteoglycin levels were high in patients with CAD, they did not correlate with the severity of CAD and were not an independent factor for CAD. Notably, osteoglycin levels were low in patients with complex lesions and were a factor for complex lesions, suggesting that osteoglycin plays a role in coronary plaque stabilization.

Abstract
Small leucine-rich proteoglycans are emerging as important regulatory proteins within the extracellular matrix, where they exert both structural and nonstructural functions and hence are modulators of numerous biological processes, such as inflammation, fibrosis, and cell proliferation. One proteoglycan in particular, osteoglycin (OGN), also known as mimecan, shows great structural and functional diversity in normal physiology and in disease states, therefore making it a very interesting candidate for the development of novel therapeutic strategies. Unfortunately, the literature on OGN is confusing, as it has different names, and different transcript and protein variants have been identified. This review will give a clear overview of the different structures and functions of OGN that have been identified to date, portray its central role in pathophysiology, and highlight the importance of posttranslational processing, such as glycosylation, for the diversity of its functions.-Deckx, S., Heymans, S., Papageorgiou, A.-P.

Abstract
Background Mimecan plays an important role in endothelial and vascular smooth muscle cell integrity and may be involved the pathology of arterial stiffness. However, the role of mimecan in arterial stiffness in patients with hypertension is not well defined. Methods and Results A total of 116 hypertension patients and 54 healthy controls were enrolled in the investigation. Hypertensive patients were divided into 2 groups: the with arterial stiffness group (brachial-ankle pulse wave velocity [baPWV] ≥1400 cm/s; n=83) and the without arterial stiffness group (baPWV <1400 cm/s; n=33). A noninvasive measure of vascular stiffness was performed using pulse wave velocity (PWV) measurement of baPWV. Hypertensive patients had higher baPWV, mimecan, and endothelin 1 (ET-1) than healthy controls. The arterial stiffness group had higher mimecan and endothelin 1 (ET-1) and lower ankle-brachial pressure index (ABI) than those without stiffness. In hypertensive patients, mimecan was inversely correlated with ABI (P<0.05) and positively correlated with baPWV, ET-1, and total cholesterol. On multivariable logistic regression analysis, diastolic blood pressure, mimecan, ET-1, and creatinine were independent predictors of arterial stiffness in hypertensive patients (P<0.05). Conclusions Mimecan levels are higher in hypertensive patients than in healthy controls. Increased plasma mimecan levels are independently associated with increased arterial stiffness as assessed by baPWV.

Abstract
Cell microenvironment has a critical role determining cell fate and modulating cell responses to injuries. Hyaluronan (HA) is a ubiquitous extracellular matrix glycosaminoglycan that can be considered a signaling molecule. In fact, interacting with several cell surface receptors can deeply shape cell behavior. In vascular biology, HA triggers smooth muscle cells (SMCs) dedifferentiation which contributes to vessel wall thickening. Furthermore, HA is able to modulate inflammation by altering the adhesive properties of endothelial cells. In hyperglycemic conditions, HA accumulates in vessels and can contribute to the diabetic complications at micro- and macrovasculature. Due to the pivotal role in favoring atherogenesis and neointima formation after injuries, HA could be a new target for cardiovascular pathologies. This review will focus on the recent findings regarding the regulation of HA synthesis in human vascular SMCs. In particular, the effects of the intracellular HA substrates availability, adenosine monophosphate-activated protein kinase (AMPK), and protein O-GlcNAcylation on the main HA synthetic enzyme (i.e., HAS2) will be discussed.
