BACKGROUND AND OBJECTIVE Galectin-3 is involved in many physical and pathologic process, and is closely correlated with tumorigenesis, development and metastasis. The aim of this study is to investigate the gene expression and significance of Galectin-3 in normal lung tissue and non-small cell lung cancer (NSCLC) tissue. METHODS Gene expression was examined using the immunohistochemical S-P m...

BACKGROUND Galectin-3 is a soluble ß-galactoside-binding lectin released by activated cardiac macrophages. Galectin-3 has been proposed for diagnosis and prognosis of HF patients. OBJECTIVES The present study aimed to investigate the relationship between galectin-3 as a biomarker and ejection fraction and functional capacity in the patients with compensated systolic heart failure. PATIENTS ...

Galectin-3 is a versatile molecule which exerts several and sometimes opposite functions in various pathophysiological processes. Recently, galectin-3 has gained attention as a powerful predictor of heart failure and mortality, thus becoming a useful prognostic marker in clinical practice. Moreover, though not specifically investigated in diabetic cohorts, plasma levels of galectin-3 correlated...

This review summarizes the current literature regarding the involvement and the putative role(s) of galectin-3 in post-myocardial infarction cardiac remodeling. Post-myocardial infarction remodeling is characterized by acute loss of myocardium, which leads to structural and biomechanical changes in order to preserve cardiac function. A hallmark herein is fibrosis formation, both in the early an...

In order to study the role of galectin-3 in tumor angiogenesis associated with tumor-associated macrophages (TAM) and tumor parenchyma, the galectin-3 expression was reconstituted in Tm1 melanoma cell line that lacks this protein. Galectin-3-expressing cells (Tm1G3) and mock-vector transfected cells (Tm1N3) were injected into wild-type (WT) and galectin-3 knockout (KO) C57Bl/6 mice. Tumors orig...

ST6GalNAc-I, the sialyltransferase responsible for sialyl-Tn (sTn) synthesis, has been previously reported to be positively associated with cancer aggressiveness. Here we describe a novel sTn-dependent mechanism for chemotherapeutic resistance. We show that sTn protects cancer cells against chemotherapeutic-induced cell death by decreasing the interaction of cell surface glycan receptors with g...

INTRODUCTION Galectin-9 ameliorates various inflammatory conditions including autoimmune diseases by regulating T cell and macrophage/dendritic cell (DC) functions. However, the effect of galectin-9 on polymicrobial sepsis has not been assessed. METHODS We induced polymicrobial sepsis by cecal ligation and puncture (CLP) in mice. The survival rate was compared between galectin-9- and PBS-trea...

BACKGROUND The term nasal polyposis describes benign growth processes in the nasal and sinus mucosa, which are mainly located in the middle meatus and never in the inferior meatus. As a step to define the biochemical determinants relevant for growth regulation, we focused on endogenous lectins known for anti-apoptotic (galectin-3) and immunomodulatory (galectin-1) activities. DESIGN Using com...

The immune system recognizes diverse melanoma antigens. However, tumors can evade the immune response, therefore growing and progressing. It has been reported that galectin-3 and galectin-1 can induce apoptosis of activated lymphocytes. However, there is strong evidence indicating that the regulation of galectins function in the human tumor microenvironment is a complex process that is influenc...

There are more than 3.4 million deaths every year in the world due to overweight and obesity. Obesity is a chronic proinflammatory condition marked by increased lipid adipose tissues, leading ectopic fat accumulation with levels of cytokines. causes progressive increase galectin-3 expression, especially visceral subcutaneous tissue experimental animals. Galectin-3 upregulated obesity defined as...
