Possible Interaction: Sphingosine 1-Phosphate and Epigallocatechin

Research Papers that Mention the Interaction

By contrast, EGCG markedly suppressed the phosphorylations of both Akt and glycogen synthase kinase-3beta stimulated by sphingosine 1-phosphate.
EGCG significantly reduced the induction of HSP27 stimulated by sphingosine 1-phosphate in a dose-dependent manner between 10 and 30 microM. Immunofluorescence microscopy studies revealed that sphingosine 1-phosphate certainly stimulated the induction of HSP27 in the cytosol of these cells, and that EGCG clearly suppressed its induction.
These results strongly suggest that EGCG suppresses the induction of HSP27 stimulated by sphingosine 1-phosphate via attenuation of, not the p38 MAP kinase pathway, but of the phosphatidylinositol 3-kinase/Akt pathway in osteoblasts.
