The alteration of glucose metabolism, through increased uptake of glucose and glutamine addiction, is essential to cancer cell growth and invasion. Increased flux of glucose through the Hexosamine Biosynthetic Pathway (HBP) drives increased cellular O-GlcNAcylation (hyper-O-GlcNAcylation) and contributes to...

A promising approach to understanding the mechanistic basis of speech is to study disorders that affect speech without compromising other cognitive or motor functions. Stuttering, also known as stammering, has been linked to mutations in the lysosomal enzyme-targeting pathway,...

Downregulation of O-linked N-acetylglucosamine transferase by RNA interference decreases MMP9 expression in human esophageal cancer cells.

O-linked N-acetylglucosamine transferase (OGT) catalyzes O-linked glycosylation (O-GlcNAcylation). O-GlcNAcylation is a post-translational carbohydrate modification of diverse nuclear and cytosolic proteins by the addition of O-linked β-N-acetylglucosamine. It was recently demonstrated that OGT and the level of O-GlcNAcylation are upregulated...

During pregnancy, the placentae of ungulate mammals (e.g., cows, sheep, and pigs) convert glucose into fructose which is the most abundant hexose sugar in fetal fluids and blood. However, the role of fructose, the most enigmatic component of carbohydrate...

Bitterness in sugar: O-GlcNAcylation aggravates pre-B acute lymphocytic leukemia through glycolysis via the PI3K/Akt/c-Myc pathway.

Abnormal cellular energetics has emerged as a hallmark of cancer cells. Deregulating aerobic glycolysis can alter multiple metabolic and signaling pathways in cancer cells, and trigger unlimited growth and proliferation. Accumulating evidence suggests that elevated levels of protein modification...

Vibrio cholerae O1 El Tor attachment to chitin and biofilm formation on polyvinylchloride surfaces via the N-acetylglucosamine-binding protein A (GbpA) and the mannose-sensitive haemagglutinin (MSHA) were investigated under different temperature and salinity conditions simulating those found in the aquatic...

Ontogenetic changes of the soluble and membrane-bound D2 glycoprotein in rat forebrain.

International journal of developmental neuroscience : the official journal of the International Society for Developmental Neuroscience

A soluble form of the D2 glycoprotein, detected in the rat brain hypotonic extract, is described. Its specific relative concentration did not differ significantly in the three examined cerebral regions (forebrain, brainstem and cerebellum), while in the cerebellum the...

Global O-GlcNAc Levels Modulate Transcription of the Adipocyte Secretome during Chronic Insulin Resistance.

Increased flux through the hexosamine biosynthetic pathway and the corresponding increase in intracellular glycosylation of proteins via O-linked β-N-acetylglucosamine (O-GlcNAc) is sufficient to induce insulin resistance (IR) in multiple systems. Previously, our group used shotgun proteomics to identify multiple...
