MMP-13 stimulates osteoclast differentiation and activation in tumour breast bone metastases
2011
INTRODUCTION: The increased bone degradation in osteolytic metastases depends on stimulation of mature osteoclasts and on continuous differentiation of new pre-osteoclasts. Metalloproteinases (MMP)-13 is expressed in a broad range of primary malignant tumours and it is emerging as a novel biomarker. Recent data suggest a direct role of MMP-13 in dissolving bone matrix complementing the activity of MMP-9 and other enzymes. Tumour-microenvironment interactions alter gene expression in malignant breast tumour cells promoting osteolytic bone metastasis. Gene expression profiles revealed that MMP-13 was among the up-regulated genes in tumour-bone interface and its abrogation reduced bone erosion…
Galectin-3 immunodetection for improving the performance of conventional thyroid cytology: preliminay results
2008
Introduction: Most of differentiated thyroid carcinomas should be easily revealed by fine-needle aspiration cytology but sometimes preoperative diagnosis is doubtful. Galactin-3 is a carbohydrate –binding protein with affinity for beta-galactosides that plays a significant role in cell-cell and cell matrix adhesion, growth, neoplastic transformation and metastasis. Moreover, galectin-3 immunodetection is related to follicular thyroid malignancies. Our aim is to test Galectin-3 as potential preoperative marker for follicular and papillary carcinomas. Methods: Expression of galectin -3 was tested by fluorescence staining on 40 fresh cytological thyroid samples obtained preoperatively; the sam…
Galectin-3 and Lp(a) plasma concentrations and advanced carotid atherosclerotic plaques: Correlation with plaque presence and features
2019
Introduction: atherosclerosis is one of the leading causes of death and morbidity worldwide. It consists in the development of plaques in the intima media layers of arteries due to lipid accumulation and oxidation, causing massive inflammation. We aim to better understand the role of Galectin-3 (Gal-3) and Lipoprotein(a) [Lp(a)] as possible peripheral markers of plaque presence. Methods: Gal-3 and Lp(a) were measured in plasma samples from 99 patients undergoing carotid endarterectomy and 78 healthy controls, by immunometric assays. Plaques were classified histologically, according to the American Heart Association (AHA) guidelines as type Va (fibroatheroma), Vb (mainly calcific) and Vl (co…
ANMCO/ELAS/SIBioC Consensus Document: Biomarkers in heart failure
2017
Abstract Biomarkers have dramatically impacted the way heart failure (HF) patients are evaluated and managed. A biomarker is a characteristic that is objectively measured and evaluated as an indicator of normal biological or pathogenic processes, or pharmacological responses to a therapeutic intervention. Natriuretic peptides [B-type natriuretic peptide (BNP) and N-terminal proBNP] are the gold standard biomarkers in determining the diagnosis and prognosis of HF, and a natriuretic peptide-guided HF management looks promising. In the last few years, an array of additional biomarkers has emerged, each reflecting different pathophysiological processes in the development and progression of HF: …
