Abstract AIMS Kidney fibrosis, characterised by impaired extracellular matrix remodelling and excessive collagen deposition, is a hallmark of chronic kidney disease in diabetes. We investigated whether biomarkers reflecting collagen formation and degradation were associated with complications in type 1 diabetes. METHODS In this observational cohort study, markers of collagen type III (PRO-C3), VII (PRO-C7) and […]

Abstract Chronic kidney disease (CKD) is characterized by fibrosis. Alport syndrome, a common monogenic form of CKD caused by collagen type IV variants, leads to basement membrane defects and progressive fibrosis. Understanding extracellular matrix dynamics is crucial for identifying disease-specific biomarkers and optimizing therapeutic timing. We applied a discovery approach combining stable C-lysine metabolic labeling […]

Abstract BACKGROUND Novel collagen-derived circulating peptides, such as endotrophin, have been proposed as biomarkers of myocardial fibrosis. OBJECTIVES We aimed to determine the effect of pirfenidone, an antifibrotic agent, on circulating levels of these peptides, and their association with cardiovascular magnetic resonance extracellular volume (ECV). METHODS In the PIROUETTE (Pirfenidone in Patients with Heart Failure […]

Abstract UNLABELLED Endotrophin is a matrikine released from the C-terminus of the alpha-3 chain of type VI collagen, gaining increasing attention both as a biomarker and as a therapeutic target in the cardiometabolic space. So far, it has been quantified in circulation by the PRO-C6 assay, which detects different-sized proteolytic fragments of the C-terminus, including […]

Abstract BACKGROUND AND AIMS Tissue remodelling and extracellular matrix (ECM) changes are primary consequences of ST-elevated myocardial infarction (STEMI), leading to an increased risk of developing heart failure and mortality. Collagen type I is the top constituent of the cardiac ECM and is rapidly degraded at sites of tissue injury occurring in STEMI. We aimed […]

Abstract Although interest in biomarkers of biological aging is growing, consensus on reliable, non-invasive indicators remains limited. Endotrophin, a bioactive fragment released during collagen type VI formation, reflects fibroblast activation and extracellular matrix remodeling and has been linked to chronic diseases, metabolic dysfunction, and inflammation. Whether circulating endotrophin also captures aging-related phenotypes and mortality risk in […]

Abstract Endotrophin, a biologically active fragment derived from the α3 chain of collagen type VI, has emerged as both a risk biomarker and a potential pathogenic factor in cardiovascular-kidney-metabolic (CKM) syndrome. Over the past decade, research has shed light on its role in various noncommunicable diseases, emphasizing its signaling properties and diagnostic potential. Despite these […]

Abstract Cardiorenal syndrome (CRS) represents a complex interplay of pathophysiological processes that create a self-perpetuating cycle of heart and kidney dysfunction. While it is clearly understood how hemodynamic changes connect pathogenesis in the two organs, other processes are also in play. Some are the structural changes involving both the cellular and extracellular compartments that precede […]

Abstract BACKGROUND Endotrophin, a C-terminal pro-collagen type VIα3 fragment, has been shown to correlate with kidney interstitial fibrosis, kidney outcome measures and survival in various kidney diseases and kidney transplantation. In this study we investigated whether endotrophin is associated with fibrogenesis in T cell-mediated rejection (TCMR), allowing its use as a non-invasive biomarker. METHOD Plasma […]

Abstract A common hallmark of chronic kidney disease (CKD) is kidney fibrosis, which manifests as an increased deposition and turnover of collagens in the kidneys. Current clinical methods of monitoring disease progression in CKD patients do not truly reflect alterations at the tissue level without the use of invasive biopsies. Naturally occurring urinary peptides associated […]
