background: over the past century, the areas of genomics, proteomics and lipids have captured the attention of investigators worldwide. carbohydrates, have recently received increased attention through the expanding field of glycobiology; probably because they are very complex and not encoded in the genome. objectives: the purpose of this study was to express and purify recombinant human galect...

Background: Previous studies have shown that Galectin-3, a member of lectin family, is expressed in developing cartilage in mouse embryo and also in growth plate of long bones.   Objective: In the present work, the expression pattern of Galectin-3 in normal and various grades of osteoarthritic (OA) human articular cartilage has been studied.   Methods: Using immunohistochemistry and standard we...

Introduction: Galectin-3 is known as a biomarker in patients with heart failure. This protein participates in different mechanisms involved in atherosclerosis including inflammation and plaque formation. This study was conducted to investigate whether this factor could be a predictive biomarker for the severity of atherosclerosis. Materials and Methods: The study group consisted of 80 patients ...

Angiogenesis is a key event in cancer progression and therefore a promising target in cancer treatment. Galectin-1, a β-galactoside binding lectin, is up-regulated in the endothelium of tumors of different origin and has been shown to be the target for anginex, a powerful anti-angiogenic peptide with anti-tumor activity. Here we show that when bound to anginex, galectin-1 binds various glycopro...

introduction : galectin-3, a member of the family of β-galactoside-binding animal lectins, has been implicated in tumor invasion and metastasis. materials and methods : using an elisakit, we assessed the circulating levels of galectin-3 in sera from 40 oral squamous cell carcinoma (oscc) patients and from 43 healthy controls. results : serum galectin-3 levels in oscc patients were significantly...

Galectins are a family of mammalian beta-galactoside-binding proteins that positively and negatively regulate T cell death. Extracellular galectin-1 directly induces death of T cells and thymocytes, while intracellular galectin-3 blocks T cell death. In contrast to the antiapoptotic function of intracellular galectin-3, we demonstrate that extracellular galectin-3 directly induces death of huma...

Ovarian cancer is the most lethal gynecologic disease because usually, it is lately sensed, easily acquires chemoresistance, and has a high recurrence rate. Recent studies suggest that ovarian cancer stem cells (CSCs) are involved in these malignancies. Here, we demonstrated that galectin-3 maintains ovarian CSCs by activating the Notch1 intracellular domain (NICD1). The number and size of ovar...
