WebAbstract. Aminosugars produced in the hexosamine pathway (HP) are utilized in protein glycosylation reactions involved in protein maturation and cellular signaling. Recent evidence revealed a role of the HP in protein quality control and ageing. Elevation of the HP product UDP-N-acetylglucosamine in the nematode Caenorhabditis elegans results ... WebMar 5, 2024 · The Hexosamine Biosynthetic Pathway (HBP) is a branch of glycolysis responsible for the production of a key substrate for protein glycosylation, UDP-GlcNAc. Cancer cells present altered glucose metabolism and aberrant glycosylation, pointing to alterations on HBP. Recently it was demonstrated that HBP influences many aspects of …
