Isolated and perfused rat hearts were examined by two-dimensional gel electrophoresis and liquid scintillation counting for alterations in protein synthesis following incubation with L-[3H]leucine at 0.5-2.5, 2.5-4.5, or 4.5-6.5 h of perfusion. When 35-mL volumes of three different buffers were recycled for a 2-h period from 0.5 to 2.5 h, by fluorography little effect was seen on the normal patterns of protein synthesis and there was a moderate synthesis of a stress-induced protein (heat-shock protein) with a molecular mass of 71 X 10(3) daltons (SP71). However, hearts perfused with Krebs-improved Ringer 1 bicarbonate had the highest incorporation of L-[3H]leucine. When buffers were recycled for 30-min periods from 0.5 to 2.5 h, SP71 was synthesized in hearts perfused with Krebs-Henseleit original Ringer bicarbonate. Hearts perfused in a similar fashion with Krebs-improved Ringer 1 bicarbonate had the lowest incorporation of label into SP71 and in fact SP71 was undetectable on fluorograms. Overall protein synthesis was decreased and the ratio of SP71 to the total synthesis was increased at 4.5-6.5 h of perfusion when 35-mL volumes of Krebs-improved Ringer 1 bicarbonate was recycled for 2-h periods. A similar result was observed at 2.5-4.5 h of perfusion when this buffer was recycled for either the duration of the experiment or 30-min periods.
