delta-9-Tetrahydrocannabinol (THC) is a major psychoactive component of cannabis. We here studied, by quantitative in situ hybridization at the macroscopic level, the possible modulatory effects of acute THC (5 mg/kg/i.p.) on gene expression of the growth factor pleiotrophin (PTN) in the adult rat forebrain. We found, 30 min after a single injection of THC, a significant increase of PTN mRNA concentrations in the cingulate cortex (38%), fronto-parietal cortex (31%) and caudate-putamen (27%). In conclusion, this is the first report on THC regulation of growth factor gene expression in the brain.
δ-9-四氢大麻酚(THC)是大麻的主要精神活性成分。我们在此通过宏观水平的定量原位杂交研究了急性注射THC(5毫克/千克/腹腔注射)对成年大鼠前脑生长因子多效蛋白(PTN)基因表达的可能调节作用。我们发现,单次注射THC后30分钟,扣带回皮质(增加38%)、额顶叶皮质(增加31%)和尾状核-壳核(增加27%)中的PTN mRNA浓度显著升高。总之,这是关于THC对大脑中生长因子基因表达调节作用的首次报道。
