Impaired plasma membrane glycoprotein assembly in the liver following acute ethanol administration
Abstract:
The in vivo effects of acute ethanol administration on hepatic plasma membrane assembly were studied in the rat. When [14C]fucose and [3H]N-acetylmannosamine, a sialic acid precursor, were injected following an acute dose of ethanol, minimal effects on fucose and a slight reduction of sialic acid incorporation into the total pool of hepatic membrane glycoproteins were observed. However, the assembly of labeled fucoproteins and sialoproteins into the plasma membrane was markedly inhibited in the ethanol-treated animals. These results indicate that ethanol administration impairs the late stages of membrane assembly which include the transport of glycoproteins from the Golgi complex to the plasma membrane and/or the insertion of glycoproteins into the membrane.
