Galectin family members have been shown to exert multiple roles in the context of tumor biology. Several recent findings support a similar multi-faceted role for galectin-9. Galectin-9 expression is frequently altered in cancer as compared to normal tissues. In addition, an increasing amount of evidence suggests that galectin-9 is involved in several aspects of tumor progression, including tumo...

BACKGROUND Heart failure is accompanied by abnormalities in ventricular-vascular interaction due to increased myocardial and arterial stiffness. Galectin-3 is a recently discovered biomarker that plays an important role in myocardial and vascular fibrosis and heart failure progression. OBJECTIVES The aim of this study was to determine whether galectin-3 is correlated with arterial stiffening ...

Innate immune response is important for viral clearance during influenza virus infection. Galectin-1, which belongs to S-type lectins, contains a conserved carbohydrate recognition domain that recognizes galactose-containing oligosaccharides. Since the envelope proteins of influenza virus are highly glycosylated, we studied the role of galectin-1 in influenza virus infection in vitro and in mic...

The aim of the present study was to investigate the expression levels of the T-cell immunoglobulin and mucin domain-containing protein-3 (TIM-3) and galectin-9 proteins and their clinical value in esophageal squamous cell carcinoma (ESCC) in Chinese patients. The expression profiles of TIM-3 and galectin-9 in ESCC were determined by the immunohistochemical analysis of the postoperative patholog...

Many infectious diseases are characterized by the development of immunoregulatory pathways that contribute to pathogen persistence and associated disease symptoms. In diseases caused by intracellular parasites, such as visceral leishmaniasis (VL), various immune modulators have the capacity to negatively impact protective CD4+ T cell functions. Galectin-1 is widely expressed on immune cells and...

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...

The utility of CEA and CA19-9 as colorectal carcinoma (CRC) markers is limited and development of additional reliable markers is under investigation. We previously showed that galectin-1 is overexpressed in CRC tissues. If such a protein leaks into the peripheral circulation, it might constitute a tumor marker candidate. Here, we test the hypothesis that the levels of circulating galectins coul...

BACKGROUND Galectin-3 has been implicated in the development of organ fibrosis. It is unknown whether it is a relevant therapeutic target in cardiac remodeling and heart failure. METHODS AND RESULTS Galectin-3 knock-out and wild-type mice were subjected to angiotensin II infusion (2.5 µg/kg for 14 days) or transverse aortic constriction for 28 days to provoke cardiac remodeling. The efficacy ...

Protein O–GlcNAcylation has been associated with neurodegenerative diseases such as Alzheimer’s disease (AD). The of the Amyloid Precursor (APP) regulates both trafficking and processing APP through amyloidogenic pathway, resulting in release aggregation Aβ1–42 peptide. Microglia clears Aβ aggregates dead cells to maintain brain homeostasis. Here, using LC-MS/MS, we revealed that oligomers modi...

Galectin-3 is a member of a growing family of animal beta-galactoside-binding proteins shown to be involved in cell growth, differentiation, apoptosis resistance, and tumor progression. In the present study, we investigated whether galectin-3 can protect against apoptosis induced by the loss of cell anchorage (anoikis). Because studies suggest that cellular sensitivity to anoikis is associated ...
