INTRODUCTION: Breast cancers develop different patterns of sialylation to modulate their tumor-infiltrating lymphocyte (TIL) environment. We studied the relationship between α-2,6 sialyltransferases and the TIL in different breast cancer molecular subgroups.MATERIALS AND METHODS: Immunohistochemical preparations were made from 39...

A Cartography of Siglecs and Sialyltransferases in Gynecologic Malignancies: Is There a Road Towards a Sweet Future?.

Frontiers in oncology

Front Oncol. 2018 Mar 13;8:68. doi: 10.3389/fonc.2018.00068. eCollection 2018.

Altered surface glycosylation is a key feature of cancers, including gynecologic malignancies. Hypersialylation, the overexpression of sialic acid, is known to promote tumor progression and to dampen antitumor responses by mechanisms that also involve sialic acid binding immunoglobulin-like lectins...

α2,6-Sialylation mediates hepatocellular carcinoma growth in vitro and in vivo by targeting the Wnt/β-catenin pathway.

Oncogenesis. 2017 May 29;6(5):e343. doi: 10.1038/oncsis.2017.40.

Abnormal sialylation due to overexpression of sialyltransferases has been associated with tumorigenesis and tumor progression. Although ST6Gal-I influences cancer persistence and progression by affecting various receptors, the underlying mechanisms and mediators remain largely obscure, especially in hepatocellular carcinoma (HCC)....

BACKGROUND: Sialyltransferases (SIATs) are a family of enzymes that transfer sialic acid (Sia) to glycan chains on glycoproteins, glycolipids, and oligosaccharides. They play key roles in determining cell-cell and cell-matrix interactions and are important in neuronal development, immune regulation,...

ST3Gal IV is one of the principal sialyltransferases responsible for the biosynthesis of α2, 3-sialic acid to the termini

Glycation Interferes with the Expression of Sialyltransferases in Meningiomas.

Cells

Selke P, Bork K, Zhang T, Wuhrer M, Strauss C, Horstkorte R, Scheer M.

Meningiomas are the most common non-malignant intracranial tumors and prefer, like most tumors, anaerobic glycolysis for energy production (Warburg effect). This anaerobic glycolysis leads to an increased synthesis of the metabolite methylglyoxal (MGO) or glyoxal (GO), which is known...

Cell Line-, Protein-, and Sialoglycosite-Specific Control of Flux-Based Sialylation in Human Breast Cells: Implications for Cancer Progression.

Sialylation, a post-translational modification that impacts the structure, activity, and longevity of glycoproteins has been thought to be controlled primarily by the expression of sialyltransferases (STs). In this report we explore the complementary impact of metabolic flux on sialylation...

Expression of α2,6-sialic acid-containing and Lewis-active glycolipids in several types of human ovarian carcinomas.

To identify glycolipid antigens associated with histologically defined types of ovarian carcinomas, we determined the amounts of α2,6-sialyl and Lewis-active glycolipids, the specific activities of the α2,3- and α2,6-sialyltransferases, and the gene expression of sugar transferases in mucinous and...

Gangliosides have attracted much attention due to their important biological properties. Herein, we report the first chemoenzymatic syntheses of two globo series of ganglioside oligosaccharides, Globo-H 1 and stage-specific embryonic antigen-4 (SSEA-4) 2. The common precursor SSEA-3 pentasaccharide for...

Group B streptococci, Streptococcus agalactiae, produce high-molecular-weight polysaccharides containing N-acetylneuraminic acid. Although the type-specific capsular polysaccharide (CP) synthesis (cps) genes of several S. agalactiae strains have been extensively analyzed, to date, no sialyltransferase activity has been detected from any...

Glycans play important roles in such cell-cell interactions as signaling and adhesion, including processes involved in pathogenic infections, cancers, and neurological diseases. Glycans are biosynthesized by multiple glycosyltransferases (GTs), which function sequentially. Excluding mucin-type O-glycosylation, the non-reducing terminus of...
