- Astrocytes regulate brain metabolism and homeostasis, but how oxidative stress reshapes astrocytic metabolism to drive neuronal damage remains unclear. Here, we demonstrate that oxidative stress turns on astrocytic type I collagen (COL1) production via a redox-glycosylation coupling mechanism. Hydrogen peroxide (HO) suppresses miR-29 and enhances fucosyltransferase 8 (FUT8)-mediated core fucosylation, integrating post-transcriptional and glycosylation-dependent regulation of COL1. Astrocyte-derived COL1 activates integrin signaling and promotes neuronal death. In a photothrombotic stroke model, an HO surge induces astrogliosis, glycosylation remodeling, and COL1 expression, leading to glial barrier formation, neuronal loss, and neurological deficits. These pathological cascades are mitigated by astrocyte-specific silencing of COL1 or FUT8 or by KDS12025, a peroxidase enhancer that reduces HO burden. Notably, KDS12025 exerts potent neuroprotection in a non-human primate stroke model. Together, our findings identify an unprecedented astrocytic metabolic pathway linking oxidative stress to glycosylation-driven COL1 production, highlighting the HO surge, astrocytic COL1, and FUT8 as promising therapeutic targets for recovery after stroke. - Source: PubMed

In general, pathophysiological changes are defined by comparing knock-out (KO) or knock-in mice generated using CRISPR-Cas9 and other technologies to normal mice. Next, target molecules such as glycoproteins, glycolipids, and proteoglycans to which various biosynthetic glycans bind were identified. As a result, we found that N-glycan branches biosynthesized by glycosyltransferases are intrinsically involved in Alzheimer's disease, cancer metastasis, epithelial mesenchymal transition (EMT)/mesenchymal epithelial transition (MET), type 2 diabetes, chronic obstructive pulmonary disease (COPD), and ulcerative colitis. For example, the addition of core fucose biosynthesized by α1,6-fucosyltransferase (Fut8) leads to dysregulation of TGF-β receptors. Bisecting N-acetylglucosamine (GlcNAc) biosynthesized by β-1,4-GlcNAc transferase III (GnT-III) affects the subcellular localization of Beta-site Amyloid Precursor Protein Cleaving Enzyme 1 (β-secretase 1, referred to as BACE1). β1,6GlcNAc branching biosynthesized by GnT-V leads to the modification of matrix metalloproteinase (MMP). Identification and characterization of N-glycan structures on these proteins were performed using a glycoproteomic approach based on lectin blotting, western blotting, liquid chromatography-electron spray ionization mass spectrometry, and histochemical staining. Recently, studies concerning redox regulation of N-glycans, termed Glyco-Redox, have emerged as a promising approach. Functional and pathophysiological glycan studies are one of the main goals of glycobiology research. In this review, we describe the role of N-glycan branching glycosyltransferases and their biosynthesized glycans in relation to various diseases, such as cancer metastasis, COPD, Alzheimer's disease, and ulcerative colitis. - Source: PubMed

Taniguchi NaoyukiOhkawa YukiNakano MiyakoGu JianguoTakahashi Motoko - Core fucosylation, a critical post-translational modification mediated by α1,6-fucosyltransferase (Fut8), is vital in regulating cellular functions and signaling pathways. This glycosylation process is particularly significant in the context of the central nervous system (CNS), where it influences neurodevelopment, synaptic functionality, and the neuroinflammatory response. Aberrations in core fucosylation have been implicated in the pathogenesis of various neuroinflammatory conditions, underscoring its potential as a therapeutic target for neurological disorders. Core fucosylation affects several important signaling molecules and receptors, such as the transforming growth factor-β (TGF-β) receptor, vascular endothelial growth factor receptor (VEGFR), epidermal growth factor receptor (EGFR), integrins, and glycoprotein 130 (gp130). These molecules are essential for maintaining CNS homeostasis and responding to injury or disease. Furthermore, the dysregulation of core fucosylation has been associated with altered microglial and astrocytic responses to inflammatory stimuli, affecting the progression of neurodegenerative diseases. The modulation of core fucosylation pathways presents a promising avenue for developing novel therapeutic strategies to control neuroinflammation and improve outcomes in patients with neurodegenerative disorders. In conclusion, the intricate relationship between core fucosylation and neuroinflammation offers insights into the molecular mechanisms underlying CNS pathologies and highlights the importance of further research in this area to identify new targets for therapeutic intervention. - Source: PubMed
Xu XingFukuda TomohikoGu Jianguo - Clear cell renal cell carcinoma (ccRCC) is characterized by the loss of the von Hippel-Lindau (VHL) gene, leading to constitutive activation of hypoxia-inducible transcription factors (HIFs) and metabolic reprogramming toward aerobic glycolysis. Although core fucosylation catalysed by fucosyltransferase 8 (FUT8) is known to regulate receptor signaling and tumor malignancy, its role in metabolic regulation of ccRCC remains poorly defined. Here, we demonstrate that FUT8 knockdown significantly suppresses ccRCC proliferation and migration both in vitro and in vivo. Mechanistically, FUT8 enhances HIF-1α-driven glycolysis, increasing lactate production and promoting pan-lysine lactylation (pan-Kla). Specifically, FUT8 promotes pyruvate kinase M2 (PKM2) K115 lactylation, which boosts its enzymatic activity while reducing nuclear localization, thereby driving epithelial-mesenchymal transition and malignant progression. Collectively, our findings reveal the FUT8-HIF-1α-lactate-PKM2 axis as a key mechanism that links core fucosylation to metabolic reprogramming and malignant progression in ccRCC and highlights FUT8 as a promising therapeutic target. - Source: PubMed

Guo ZikaiJiang HongxiaoWang XuXuan KeZhong HuidongLiu ChengxiZhang MengkaiLi ZhichaoHuang WeirenSun Yangyang - Glycosylation is a critical post-translational modification of proteins. The proper function and expression of cell-surface proteins-including receptors, transporters, and cell adhesion molecules-depends on glycosylation. Among the various forms of glycosylation, core fucose applied to N-glycans exhibits distinctive characteristics and plays a significant role in numerous biological processes. Here, we focus on the molecular targets of core fucose and review their functions involved in inflammatory signaling pathways and immune systems. Cytokine receptors and toll-like receptors are important targets of core fucosylation. Additionally, core fucosylation of immunoglobulin G (IgG) plays a significant role in regulating antibody-dependent cellular cytotoxicity (ADCC). Recent studies-including ours-also indicate that the level of core fucose of IgG could serve as a valuable biomarker for monitoring inflammatory status in individuals. Modulation with monosaccharide fucose is a small event for the target molecules, but core fucose exerts a significant impact on inflammation. - Source: PubMed
