1 Inhibition of glycosylation with tunicamycin permitted identification of the nonglycosylated form of secreted angiotensinogen. Tunicamycin angiotensinogen Rattus norvegicus
2 Whereas angiotensinogen secreted by hepatoma cells and hepatocytes showed electrophoretic heterogeneity (mol wt, 52-62 X 10(3], tunicamycin-treated cells secreted only a single angiotensinogen species [mol wt, 48.3 +/- 0.7 X 10(3) (mean +/- SD)], which could be cleaved by renin. Tunicamycin angiotensinogen Rattus norvegicus
3 4) The des-angiotensin I-angiotensinogen generated by renin treatment of the lysate had an electrophoretic mobility identical to that of des-AI-angiotensinogen produced by renin treatment of nonglycosylated angiotensinogen secreted by tunicamycin-treated hepatoma cells and hepatocytes. Tunicamycin angiotensinogen Rattus norvegicus
