Tramadol 0-8 cAMP responsive element binding protein 1 Rattus norvegicus 69-73 30632799-11 2019 RESULTS: In the NAC, acute tramadol exposure increases the levels of MOR and p-CREB. Tramadol 27-35 cAMP responsive element binding protein 1 Rattus norvegicus 79-83 30632799-12 2019 Moreover, chronic tramadol administration in this region results in elevated levels of MOR, DeltaFosB and p-CREB compared with saline-treated rats. Tramadol 18-26 cAMP responsive element binding protein 1 Rattus norvegicus 108-112 30632799-13 2019 The levels of MOR and p-CREB in the PFC increased in both acute and chronic tramadol exposure. Tramadol 76-84 cAMP responsive element binding protein 1 Rattus norvegicus 24-28 30632799-16 2019 CONCLUSION: We concluded that both CREB and DeltaFosB played a role in tramadol dependence. Tramadol 71-79 cAMP responsive element binding protein 1 Rattus norvegicus 35-39
