1 Docosahexaenoic acid down-regulates phenobarbital-induced cytochrome P450 2B1 gene expression in rat primary hepatocytes via the sphingomyelinase/ceramide pathway. Phenobarbital cytochrome P450 2B1 Rattus norvegicus
2 In addition, the cAMP-dependent PKA pathway down-regulates CYP 2B1 expression induced by phenobarbital (PB). Phenobarbital cytochrome P450 2B1 Rattus norvegicus
3 In addition, the cAMP-dependent PKA pathway down-regulates CYP 2B1 expression induced by phenobarbital (PB). Phenobarbital cytochrome P450 2B1 Rattus norvegicus
4 In the present study, we determined the effect of DHA on SMase transactivation and the downstream pathway in CYP 2B1 expression induced by PB. Phenobarbital cytochrome P450 2B1 Rattus norvegicus
5 SMase was activated by DHA 2 h after treatment, and D609 (an SMase inhibitor) attenuated the inhibition of PB-induced CYP 2B1 expression by DHA. Phenobarbital cytochrome P450 2B1 Rattus norvegicus
6 C2-ceramide dose-dependently inhibited PB-induced CYP 2B1 expression and increased intracellular cAMP concentrations. Phenobarbital cytochrome P450 2B1 Rattus norvegicus
7 SQ22536 (an adenylyl cyclase inhibitor) and H89 (a PKA-specific inhibitor) partially reversed the inhibition of PB-induced CYP 2B1 expression by C2-ceramide. Phenobarbital cytochrome P450 2B1 Rattus norvegicus
