Paramyxovirus replication induces the Hexosamine Biosynthetic Pathway and Mesenchymal Transition via the IRE1a-XBP1s arm of the Unfolded Protein Response

Paramyxovirus replication induces the Hexosamine Biosynthetic Pathway and Mesenchymal Transition via the IRE1a-XBP1s arm of the Unfolded Protein Response

The paramyoxviridae, Respiratory Syncytial Virus (RSV) and murine respirovirus are enveloped, negative-sense RNA viruses that are the etiological agents of vertebrate respiratory tract infections (LRTIs). We observe RSV infection in human small airway epithelial cells induces accumulation of glycosylated proteins within the ER, increased Glutamine-Fructose-6-Phosphate Transaminases (GFPT1/2), and accumulation of UDP-N-acetylglucosamine, indicating activation of the hexosamine biosynthetic pathway (HBP). RSV infection induces rapid formation of spliced X-box...
