1 Epigallocatechin gallate (EGCG) mimics insulin action on the transcription factor FOXO1a and elicits cellular responses in the presence and absence of insulin. epigallocatechin gallate insulin Homo sapiens
2 Epigallocatechin gallate (EGCG) mimics insulin action on the transcription factor FOXO1a and elicits cellular responses in the presence and absence of insulin. epigallocatechin gallate insulin Homo sapiens
3 The green tea flavonoid epigallocatechin gallate (EGCG) is one of several compounds that have been reported to have insulin-like glucose-lowering properties in mammals. epigallocatechin gallate insulin Homo sapiens
4 We show here that EGCG induces phosphorylation of insulin-sensitive residues on the transcription factor FOXO1a. epigallocatechin gallate insulin Homo sapiens
5 Like insulin, EGCG induced FOXO1a phosphorylation is abolished by the PtdIns 3-kinase inhibitor LY294002 but not by PD98059 (an inhibitor of mitogen-activated protein kinase cascade) or by rapamycin (an inhibitor of signalling to p70 S6 kinase). epigallocatechin gallate insulin Homo sapiens
6 These results indicate that EGCG exerts its insulin mimetic effects at least in part by phosphorylation of the FOXOs through a mechanism that is similar but not identical to insulin and IGF-1 induced FOXO phosphorylation. epigallocatechin gallate insulin Homo sapiens
