Possible involvement of phospholipase A(2) and cyclooxygenase in stimulatory action of L-histidine on protein synthesis in L6 myotubes.
Effects of L-histidine and related compounds on protein synthesiswere studied in cultured L6 myotubes. L-Histidine specifically stimulated protein synthesis, whereas D-histidine, histamine, L-arginine and L-lysine did not. Inhibitors of phospholipase A(2), phospholipase C and cyclooxygenase intercepted the stimulatory action of L-histidine on protein synthesis, while inhibitors of protein kinase C and 5-lipoxygenase did not. These results suggest an involvement of phospholipase A(2) and cyclooxygenase in the stimulatory action of L-histidine on protein synthesis in L6 myotubes.
