Morphine 185-193 tyrosine hydroxylase Rattus norvegicus 25-45 30517913-2 2018 We studied whether morphine-induced changes in mRNA levels of the catecholamine biosynthesis enzyme, tyrosine hydroxylase (TH), are associated with histone modifications around the promoter of this gene in the locus coeruleus (LC) and ventral tegmental area (VTA) of rats. Morphine 19-27 tyrosine hydroxylase Rattus norvegicus 101-121 30517913-2 2018 We studied whether morphine-induced changes in mRNA levels of the catecholamine biosynthesis enzyme, tyrosine hydroxylase (TH), are associated with histone modifications around the promoter of this gene in the locus coeruleus (LC) and ventral tegmental area (VTA) of rats. Morphine 19-27 tyrosine hydroxylase Rattus norvegicus 123-125 30517913-5 2018 RESULTS: Analysis of our real-time quantitative reverse transcription PCR results by 1-way ANOVA showed significant upregulation (5.13 +- 0.39 folds) of LC levels of the TH transcript 24 h after the last injection of morphine to rats, when compared with 2 h and 7 days time points. Morphine 217-225 tyrosine hydroxylase Rattus norvegicus 170-172 30517913-7 2018 Consistently, chromatin immunoprecipitation real-time quantitative PCR assays revealed that 24 h after the last injection of morphine, levels of H3 acetylation were significantly increased (4.12 +- 0.38 folds) at the promoter of the TH gene in the LC but not in the VTA. Morphine 125-133 tyrosine hydroxylase Rattus norvegicus 233-235 30517913-9 2018 CONCLUSIONS: Results of the present study, for the first time, demonstrate the involvement of histone H3 acetylation in the regulation of TH gene expression in the LC of rats during forced abstinence from morphine.
