The effect of chronic ethanol feeding on pancreatic protein synthesis was assessed by studying the rate of incorporation of [3H]leucine into proteins in isolated rat pancreatic acini in vitro. Chronic ethanol feeding increased the rate of protein synthesis (2-3-fold) compared to controls fed an isocaloric diet. The onset of the increase in protein synthesis was detectable 2 days after the beginning of ethanol feeding, reached a maximum after 7 days and remained constant for up to 4 months. The increased incorporation of [3H]leucine was not due to an increased turnover of proteins as measured in pulse-chase experiments. After separation of individual digestive enzymes by SDS-polyacrylamide gel electrophoresis and determination of the distribution of radioactivity in different proteins, a general increase in the rate of incorporation of the label into all of the proteins was observed. In contrast to the observations made with isolated acini, there was no significant difference between the control and ethanol-fed groups when the rate of pancreatic protein synthesis was measured in vivo. However, overnight withdrawal of ethanol led to an increase of approx. 70% in protein synthesis in the ethanol-fed group. These results suggest that chronic ethanol ingestion modifies the control of pancreatic protein synthesis; the enhanced protein synthesis is expressed in isolated acini, i.e., in the absence of physiological factors present during chronic ethanol ingestion and in vivo after ethanol withdrawal.
