Radiotherapy induces galectin-1 (Gal-1) secretion by tumors, which induces CD8(+) T-cell apoptosis and lymphopenia. These effects are substantially decreased by Gal-1 shRNA. Inhibition of Gal-1 may be an effective strategy for overcoming radiation-induced lymphopenia, which may improve clinical outcomes.
نارسایی قلبی یکی از شایع ترین اختلالات قلبی عروقی است که به عنوان یک اختلال مزمن، پیش رونده و ناتوان کننده مطرح می باشد. شیوع و بروز این بیماری با افزایش سن بالا رفته، به طوری که در کشورهای غربی حدود 1 تا 2 درصد بزرگسالان از این بیماری رنج می برند. از سوی دیگر پیشرفت در اقدامات درمانی و جراحی سبب شده بیمارانی که از مرگ در اثر سکته قلبی جان سالم به درمی برند متعاقباً به نارسایی قلبی مبتلا شوند. ل...
BACKGROUND Several clinical studies have evaluated the association between galectin-3 levels and outcome in patients with heart failure (HF). However, little is known about the predictive value of repeated galectin-3 measurements. This study evaluates the prognostic value of repeated time-dependent galectin-3 measurements in acute HF patients. METHODS AND RESULTS In the TRIUMPH (Translational...
In mice, alveolarization occurs during postnatal days 4 through 12, when secondary alveolar septae create thin-walled alveoli in the distal lung. We hypothesized that genes predominantly expressed in newly forming secondary alveolar septae influence the process of alveolarization. To address this hypothesis, tips of secondary alveolar septae were isolated from sections of postnatal day 6 mouse ...
OBJECTIVES Many efforts have shown multi-oncologic roles of galectin-3 for cell proliferation, angiogenesis, and apoptosis. However, the mechanisms by which galectin-3 is involved in cell proliferation are not yet fully understood, especially in human colon cancer cells. METHODS To cluster genes showing positively or negatively correlated expression with galectin-3, we employed human colon ca...
Maintenance of an intact mucosal barrier is critical to preventing damage to and infection of wet-surfaced epithelia. The mechanism of defense has been the subject of much investigation, and there is evidence now implicating O-glycosylated mucins on the epithelial cell surface. Here we investigate a new role for the carbohydrate-binding protein galectin-3 in stabilizing mucosal barriers through...
Galectin-1 belongs to an evolutionarily conserved family of animal beta-galactoside-binding proteins, which exert their functions by crosslinking the oligosaccharides of specific glycoconjugate ligands. During the past decade, attempts to identify the functional role of galectin-1 suggested participation in the regulation of the immune response. Only in the last few years has the molecular mech...
Seek a cell anchorage galectin bridge: Transforming the wildtype Galectin (Gal)-1 and -3 to tandem-repeat type variant via rational protein engineering enhanced cis-binding activity with O-Mannosylated core M1 glycopeptides of α-dystroglycan (DG). Furthermore, Gal-1 variants (but not Gal-3 variants) demonstrated trans-bridging prepared α-DG core-M1 glycoconjugates laminins in situ carbohydrate-...
Galectin-3 is a biomarker of fibrosis and atrial remodeling, involved in the mechanisms of initiation and maintenance of atrial fibrillation (AF). We sought to study the accuracy of galectin-3 level in predicting recurrences of AF after ablation. Serum concentrations of galectin-3 were determined in a consecutive series of patients addressed for AF ablation in our center. After a 3-month blanki...
