1 The glucocorticoid-Angptl4-ceramide axis induces insulin resistance through PP2A and PKCzeta. Ceramides angiopoietin-like 4 Mus musculus
2 Through metabolomic profiling, we revealed that glucocorticoid treatment increased hepatic ceramide concentrations by inducing enzymes in the ceramide synthetic pathway in an Angptl4-dependent manner. Ceramides angiopoietin-like 4 Mus musculus
3 Through metabolomic profiling, we revealed that glucocorticoid treatment increased hepatic ceramide concentrations by inducing enzymes in the ceramide synthetic pathway in an Angptl4-dependent manner. Ceramides angiopoietin-like 4 Mus musculus
4 Angptl4 was also required for glucocorticoids to stimulate the activities of the downstream effectors of ceramide, protein phosphatase 2A (PP2A) and protein kinase Czeta (PKCzeta). Ceramides angiopoietin-like 4 Mus musculus
5 Overall, our study demonstrates the key role of Angptl4 in glucocorticoid-augmented hepatic ceramide production that induces whole-body insulin resistance. Ceramides angiopoietin-like 4 Mus musculus
