WebApr 1, 2010 · Sphingosine 1-phosphate (S1P) induces diverse biological responses in various tissues by activating specific G protein-coupled receptors (S1P1–S1P5 receptors). The biological signaling regulated by S1P3 receptor has not been fully elucidated because of the lack of an S1P3 receptor-specific antagonist or agonist. We developed a novel S1P3 … WebApr 1, 2014 · The concentration of S1P (pmol/mg protein) in the lipid fraction extracted from an aliquot of HUVEC cell lysate (~50–100 μg protein) was analyzed. Pretreatment of cells with 1 μM sphingosine, a SPHK1 substrate, for 30 min prior to cell collection increased the basal level of SPHK1 activity by 40-fold (Fig. 2 A).
