Abstract：
:Signaling mechanisms for Blaberus discoidalis hypertrehalosemic hormone (Bld-HrTH)-dependent glycogen phosphorylase activation were investigated in vitro using fat body of the tropical cockroach, B. discoidalis. Brief treatment of fat bodies with Bld-HrTH in the absence of extracellular Ca2+ showed a significant activation of phosphorylase. Although extracellular Ca2+ was required for a full activation of phosphorylase by Bld-HrTH, stimulation in the absence of extracellular Ca2+ suggested that intracellular Ca2+ was also involved in Bld-HrTH signal transduction. Thapsigargin and thimerosal mobilize Ca2+ from intracellular stores by different mechanisms, and both chemicals stimulated phosphorylase activities as effectively as a maximum dose of Bld-HrTH. Bld-HrTH likely induces intracellular Ca2+ release followed by extracellular Ca2+ entry across the plasma membrane. Inositol-1,4,5-trisphosphate (InsP3) levels were greatly increased by Bld HrTH in a time- and dose-dependent manner, suggesting that InsP3 might be a Ca(2+)-mobilizing intracellular second messenger for Bld-HrTH.
