To examine how recombinant human interleukin-6, interleukin-1 beta, and tumor necrosis factor alpha regulate the synthesis and secretion of major acute-phase proteins in primary rat hepatocyte cultures.
Treated rat hepatocyte primary cultures with recombinant human interleukin-6, interleukin-1 beta, and tumor necrosis factor alpha.
Measured acute-phase protein synthesis and secretion via [35S]methionine metabolic labeling and immunoprecipitation.
Conducted pulse-chase experiments and tunicamycin-mediated inhibition of N-glycosylation to evaluate protein secretion pathways.
Interleukin-6 stimulated alpha 2-macroglobulin and cysteine proteinase inhibitor synthesis by 54-fold and 8-fold, respectively, at 100 units/ml (half-maximal effect at 4 units/ml), while reducing albumin synthesis to 30% of controls.
Interleukin-1 beta induced only a twofold increase in alpha 2-macroglobulin and a 60% reduction in albumin, while dose-dependently suppressing interleukin-6-stimulated synthesis of alpha 2-macroglobulin and cysteine proteinase inhibitor.
Interleukin-6 accelerated the secretion of total proteins and alpha 2-macroglobulin, an effect blocked by tunicamycin inhibition of N-glycosylation, whereas tumor necrosis factor alpha caused no synthetic alterations.
