1 | We hypothesize that morphine inhibits myocardial VEGF expression by inhibiting hypoxia-induced factor 1alpha (HIF-1alpha) and the signal transduction mechanisms involving Erk-1,2 MAP kinase (p42/p44), and PI3 kinase activity (phospho-Akt). | Morphine | hypoxia inducible factor 1 subunit alpha | Rattus norvegicus |
2 | Using a rat coronary ligation model, we show that morphine treatment: (1) decreases myocardial VEGF protein expression (immunohistochemistry); (2) decreases HIF-1alpha protein expression (immunoblot); and (3) decreases phospho-Erk-1,2 and phospho-Akt expression. | Morphine | hypoxia inducible factor 1 subunit alpha | Rattus norvegicus |
3 | CONCLUSIONS: (1) Morphine inhibits hypoxia-induced VEGF transcription, in part, through an HIF-1alpha-mediated mechanism and (2) morphine inhibition of hypoxia-induced HIF-1alpha may be mediated by inhibition of ERK 1,2 MAP kinase activity and PI3 kinase activity. | Morphine | hypoxia inducible factor 1 subunit alpha | Rattus norvegicus |
