1 Protein kinase B-alpha inhibits human pyruvate dehydrogenase kinase-4 gene induction by dexamethasone through inactivation of FOXO transcription factors. Dexamethasone AKT serine/threonine kinase 1 Homo sapiens
2 Expression of constitutively active PKB alpha abrogates dexamethasone stimulation of hPDK4 promoter activity, while coexpression of constitutively active FOXO1a or FOXO3a, which are mutated to alanine at the three phosphorylation sites for protein kinase B (PKB), disrupts the ability of PKB alpha to inhibit promoter activity. Dexamethasone AKT serine/threonine kinase 1 Homo sapiens
