We have obtained the X-ray crystal structure of galectin-8 N-terminal domain (galectin-8N) with a previously reported quinoline–galactoside ligand at resolution 1.6 Å. Based on this structure, collection galactosides derivatised O3 triazole, benzimidazole, benzothiazole, and benzoxazole moieties were designed synthesised. This led to discovery 3-O-(N-methylbenzimidazolylmethyl)–galactoside Kd 1...

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 ...

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...

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 galec...

background: the up-regulation of galectin-3, galectin-9, and galectin-15 expression in the luminal and glandular epithelium was reported in preparation of the endometrium for embryo implantation at the midlutheal phase. however, no data was available regarding the expression and the distribution pattern of galectin-8 in the human endometrium during a regular menstrual cycle. objective: the curr...

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...

INTRODUCTION The aetiology and pathogenesis of ulcerative colitis (UC) are essentially unknown. Galectins are carbohydrate-binding lectins involved in a large number of physiological and pathophysiological processes. Little is known about the role of galectins in human UC. In this immunohistochemical exploratory study, both epithelial and inflammatory cell galectin expression were studied in pa...
