1 Extracellular S1P activates specific G protein-coupled receptors while intracellular S1P can mobilize Ca2+ from thapsigargin-sensitive stores. Thapsigargin sphingosine-1-phosphate receptor 1 Mus musculus
2 Importantly, [Ca2+]i increases and Ca2+ mobilization induced by the SERCA inhibitor, thapsigargin, were augmented, indicating enhanced Ca2+ storage in S1P lyase-deficient MEFs. Thapsigargin sphingosine-1-phosphate receptor 1 Mus musculus
3 The area under the time course of thapsigargin-induced [Ca2+]i increases, reflecting overall Ca2+ release, was significantly increased by more than 50% in both rapidly and slowly responding S1P lyase-deficient cells. Thapsigargin sphingosine-1-phosphate receptor 1 Mus musculus
