Fucosylation is a post‑translational modification that attaches fucose residues to protein‑ or lipid‑bound oligosaccharides. Certain fucosylation pathway genes are aberrantly expressed in several types of cancer, including non‑small cell lung cancer (NSCLC), and this aberrant expression is associated with poor prognosis in patients with cancer. However, the molecular mechanism by which these fucosylation pathway genes promote tumor progression has not been well‑characterized. The present study analyzed public microarray data obtained from NSCLC samples. Multivariate analysis revealed that altered expression of fucosylation pathway genes, including fucosyltransferase 1 (FUT1), FUT2, FUT3, FUT6, FUT8 and GDP‑L‑fucose synthase (TSTA3), correlated with poor survival in patients with NSCLC. Inhibition of FUTs by 2F‑peracetyl‑fucose (2F‑PAF) suppressed transforming growth factor β (TGFβ)‑mediated Smad3 phosphorylation and nuclear translocation in NSCLC cells. In addition, wound‑healing and Transwell migration assays demonstrated that 2F‑PAF inhibited TGFβ‑induced NSCLC cell migration and invasion. Furthermore, in vivo bioluminescence imaging analysis revealed that 2F‑PAF attenuated the metastatic capacity of NSCLC cells. These results may help characterize the oncogenic role of fucosylation in NSCLC biology and highlight its potential for developing cancer therapeutics.

Objective: Osteoarthritis is a chronic degenerative disease characterised by damage to articular cartilage and degradation of the chondrocyte matrix. It has been shown that inflammation occurs with a variety of protein glycosylation abnormalities, among which elevated levels of fucosylation is one of the characteristics of OA. Now, the relationship between fucosylation and OA is not clear.

GDP-l-fucose is a universal sugar donor for the cellular biosynthesis of l-fucose-containing glycans. Its supply comes primarily from the reaction of GDP-l-fucose synthase (GFS), also known as GDP-4″-keto-6″-deoxy-d-mannose epimerase/reductase. GFS converts GDP-4″-keto-6″-deoxy-d-mannose by epimerization at both C-3″ and C-5″ followed by NADPH-dependent reduction of the carbonyl at C-4″.

Background: Fucosyltransferase 2 (FUT2)-dependent fucosylation of intestinal epithelial cells is vital for preserving gut barrier integrity and microbial balance. Nevertheless, its precise involvement in alcohol-associated liver disease has yet to be fully elucidated.
Methods: We generated mice with intestinal epithelial cell-specific Fut2 knockout (Fut2) and established a chronic-binge alcohol model.

Goblet cells are the guardians that produce MUC2 mucin that forms the protective mucus barrier as the first line of innate host defense against pathogen invasion while sustaining a healthy gut microbiota. Using an unbiased screen, we cloned a high LS174T colonic adenocarcinoma MUC2 mucin-producing goblet-like cell that revealed by whole genome sequencing, mutations that upregulated the expression of tumor suppressor , anterior gradient 2 () and mitogen-activated protein kinase kinases ( and ) genes that enhanced MUC2 biosynthesis and secretion. Hypersecretory () cells exhibited a phenotype characterized by high constitutive mRNA, upregulation of glycosyltransferases, and hypersecretion of sialylated and fucosylated MUC2 mucus enumerated by glycomics analysis.

Introduction: Cancer metastasis and associated thrombosis are significant contributors to cancerrelated mortality, necessitating therapeutic strategies that simultaneously address both issues. This study aimed to evaluate the dual anti-metastatic and anti-hypercoagulability properties of dHG-5, a low-molecular-weight fucosylated glycosaminoglycan derived from the sea cucumber Holothuria fuscopunctata.
Methods: The heparanase-inhibitory and anticoagulant effects of dHG-5 were assessed in vitro using biochemical assays.
