1 Inhibition by dexamethasone of antigen-induced c-Jun N-terminal kinase activation in rat basophilic leukemia cells. Dexamethasone mitogen-activated protein kinase 8 Rattus norvegicus
2 Pretreatment with dexamethasone (10 and 100 nM) for 18 h inhibited the Ag-induced increase in JNK activity in a concentration-dependent manner. Dexamethasone mitogen-activated protein kinase 8 Rattus norvegicus
3 At least 6 h of preincubation with dexamethasone was necessary to inhibit the Ag-induced JNK activation. Dexamethasone mitogen-activated protein kinase 8 Rattus norvegicus
4 The Ag-induced activation of the JNK kinase kinase mitogen-activated protein kinase-extracellular signal-regulated kinase kinase-1 was also inhibited by pretreatment with dexamethasone at 10 and 100 nM. Dexamethasone mitogen-activated protein kinase 8 Rattus norvegicus
5 These findings indicate that dexamethasone reduces JNK protein level and inhibits the Ag-induced activation of JNK resulting in the inhibition of c-Jun phosphorylation. Dexamethasone mitogen-activated protein kinase 8 Rattus norvegicus
6 These findings indicate that dexamethasone reduces JNK protein level and inhibits the Ag-induced activation of JNK resulting in the inhibition of c-Jun phosphorylation. Dexamethasone mitogen-activated protein kinase 8 Rattus norvegicus
