Abstract
The synthesis of proteoheparan sulfate in hepatocytes is positively regulated under acute-phase conditions produced either by turpentine or deep back incision. In both cases the incorporation of [35S]sulfate and [14C]glucosamine is doubled during a 4-h incubation period if compared with control rat hepatocytes. Neither the fractional secretion rate of heparan sulfate into the medium (less than 0.1 of cell-associated glycosaminoglycans) nor the composition of newly formed proteoglycans in hepatocytes are affected during acute phase reaction.
