1 In this study, we analyzed the effects of acute and chronic cocaine and morphine on mRNAs encoding the NGFI-B/Nur77 family of nuclear orphan receptors in reward pathways in Fischer and Lewis rats. Cocaine nuclear receptor subfamily 4, group A, member 1 Rattus norvegicus
2 In this study, we analyzed the effects of acute and chronic cocaine and morphine on mRNAs encoding the NGFI-B/Nur77 family of nuclear orphan receptors in reward pathways in Fischer and Lewis rats. Cocaine nuclear receptor subfamily 4, group A, member 1 Rattus norvegicus
3 In this study, we analyzed the effects of acute and chronic cocaine and morphine on mRNAs encoding the NGFI-B/Nur77 family of nuclear orphan receptors in reward pathways in Fischer and Lewis rats. Morphine nuclear receptor subfamily 4, group A, member 1 Rattus norvegicus
4 In this study, we analyzed the effects of acute and chronic cocaine and morphine on mRNAs encoding the NGFI-B/Nur77 family of nuclear orphan receptors in reward pathways in Fischer and Lewis rats. Morphine nuclear receptor subfamily 4, group A, member 1 Rattus norvegicus
5 After a single injection of cocaine, a similar upregulation of NGFI-B mRNA in striatal subregions and cortex cinguli was seen in both Fischer and Lewis rats. Cocaine nuclear receptor subfamily 4, group A, member 1 Rattus norvegicus
6 Morphine increased NGFI-B mRNA in medial caudate putamen and cortex cinguli in Lewis rats and Nor1 mRNA in medial caudate putamen in Fischer rats. Morphine nuclear receptor subfamily 4, group A, member 1 Rattus norvegicus
7 Chronic cocaine upregulated NGFI-B mRNA in nucleus accumbens core, lateral caudate putamen and cingulate cortex in Fischer rats, whereas no effect was seen in Lewis rats. Cocaine nuclear receptor subfamily 4, group A, member 1 Rattus norvegicus
8 Our results demonstrate different responses in addiction-prone Lewis rats as compared to the less addiction-prone Fischer rats with respect to NGFI-B and Nor1 mRNA regulation after acute and repeated administration of cocaine and morphine. Cocaine nuclear receptor subfamily 4, group A, member 1 Rattus norvegicus
