Studies on the effect of 1-deoxynojirimycin on the release of albumin, sialyltransferase and alpha 1 acid glycoprotein from liver slices from normal and inflamed rats. 1988

Liver slices from control and 24hr inflamed rats were incubated for up to 20hr with 5mM 1-deoxynojirimycin (DN), an inhibitor of the processing glucosidases. The amounts of albumin and alpha 1-acid glycoprotein (AGP) and the activities of sialyltransferase were determined in liver and medium. The presence of DN significantly inhibited the release of AGP and sialyltransferase. The inhibitory effect of DN was most pronounced with slices from inflamed rats. Secretion of albumin was not inhibited. Incorporation studies with labelled leucine and mannose showed that the inhibitor did not significantly affect protein synthesis, but it did inhibit mannose incorporation into AGP and sialyltransferase. The results show that DN inhibits the secretion of acute phase AGP and sialyltransferase in liver slices and further suggests that sialyltransferase is a glycoprotein.
