Abstract:
O-GlcNAcylation is a dynamic modulator of signaling pathways, equal in magnitude to the widely studied phosphorylation. With the rapid development of tools for its detection at the single protein level, the O-GlcNAc modification rapidly emerged as a novel diagnostic and therapeutic target in human diseases. Yet, mapping the human O-GlcNAcome in various tissues is essential for generating relevant biomarkers. In this study, we used human banked tissue as a sample source to identify O-GlcNAcylated protein targets relevant to human diseases. Using human term placentas, we propose (1) a method to clean frozen banked tissue of blood proteins; (2) an optimized protocol for the enrichment of O-GlcNAcylated proteins using immunoaffinity purification; and (3) a bioinformatic workflow to identify the most promising O-GlcNAc targets. As a proof-of-concept, we used 45 mg of banked placental samples from two pregnancies to generate intracellular protein extracts depleted of blood protein. Then, antibody-based O-GlcNAc enrichment on denatured samples yielded over 2000 unique HexNAc PSMs and 900 unique sites using 300 μg of protein lysate. Due to efficient sample cleanup, we also captured 82 HexNAc proteins with high placental expression. Finally, we provide a bioinformatic tool (CytOVS) to sort the HexNAc proteins based on their cellular localization and extract the most promising O-GlcNAc targets to explore further. To conclude, we provide a simple 3-step workflow to generate a manageable list of O-GlcNAc proteins from human tissue and improve our understanding of O-GlcNAcylation's role in health and diseases.

Park J, Lee Y, Jung EH, Kim SM, Cho H, Han IO. Glucosamine regulates hepatic lipid accumulation by sensing glucose levels or feeding states of normal and excess. Biochimica et biophysica acta. Molecular and cell biology of lipids 2020 1865(10) 32663610
Abstract:
Dose-dependent lipid accumulation was induced by glucose in HepG2 cells. GlcN also exerted a promotory effect on lipid accumulation in HepG2 cells under normal glucose conditions (NG, 5 mM) and liver of normal fed zebrafish larvae. High glucose (HG, 25 mM)-induced lipid accumulation was suppressed by l-glutamine-d-fructose 6-phosphate amidotransferase inhibitors. ER stress inhibitors did not suppress HG or GlcN-mediated lipid accumulation. HG and GlcN stimulated protein expression, DNA binding and O-GlcNAcylation of carbohydrate-responsive element-binding protein (ChREBP). Furthermore, both HG and GlcN increased nuclear sterol regulatory element-binding protein-1 (SREBP-1) levels in HepG2 cells. In contrast to its stimulatory effect under NG, GlcN suppressed lipid accumulation in HepG2 cells under HG conditions. Similarly, GlcN suppressed lipid accumulation in livers of overfed zebrafish. In addition, GlcN activity on DNA binding and O-GlcNAcylation of ChREBP was stimulatory under NG and inhibitory under HG conditions. Moreover, GlcN enhanced ChREBP, SREBP-1c, ACC, FAS, L-PK and SCD-1 mRNA expression under NG but inhibited HG-induced upregulation in HepG2 cells. The O-GlcNAc transferase inhibitor, alloxan, reduced lipid accumulation by HG or GlcN while the O-GlcNAcase inhibitor, PUGNAc, enhanced lipid accumulation in HepG2 cells and liver of zebrafish larvae. GlcN-induced lipid accumulation was inhibited by the AMPK activator, AICAR. Phosphorylation of AMPK (p-AMPK) was suppressed by GlcN under NG while increased by GlcN under HG. PUGNAc downregulated p-AMPK while alloxan restored GlcN- or HG-induced p-AMPK inhibition. Our results collectively suggest that GlcN regulates lipogenesis by sensing the glucose or energy states of normal and excess fuel through AMPK modulation.
