多巴胺转运蛋白(DAT)在运动中起作用,并且是安非他明的强制性靶点。我们设计并合成了一种针对大鼠DAT的反义肽核酸(PNA),以研究这种反义分子对运动和对安非他明的反应性的影响。每天给大鼠腹膜内注射生理盐水、反义DAT PNA、乱序DAT PNA或错配DAT PNA,持续9天。在进行初始运动性测量后的第7天和第9天,用10 mg/kg安非他明攻击动物并对运动性进行评分。在第7天,任何组的基线活动水平或对安非他明的反应之间没有显著差异。在第9天,反义PNA治疗的大鼠显示其静息运动的统计学显著增加(P < 0.01)。当这些大鼠用安非他明攻击时,盐水、乱序PNA和错配PNA治疗的动物的运动性分别显示出31、36和20倍的增加,而反义PNA治疗的动物仅显示出3.4倍的增加(P < 0.01)。ELISA结果显示,与生理盐水、乱序PNA和错配PNA对照组相比,反义PNA治疗组大鼠纹状体DAT降低32%(P < 0.001)。这些结果扩展了我们先前的发现,即脑蛋白质可以通过颅外给药的反义分子以特定的方式被敲低。此外,这些结果表明,一些新的方法来治疗依赖于多巴胺转运蛋白的功能的疾病。
The dopamine transporter (DAT) plays a role in locomotion and is an obligatory target for amphetamines. We designed and synthesized an antisense peptide nucleic acid (PNA) to rat DAT to examine the effect of this antisense molecule on locomotion and on responsiveness to amphetamines. Rats were injected intraperitoneally daily for 9 days with either saline, an antisense DAT PNA, a scrambled DAT PNA, or a mismatch DAT PNA. On days 7 and 9 after initial motility measurements were taken, the animals were challenged with 10 mg/kg of amphetamine and scored for motility. On day 7, there was no significant difference between the baseline levels of activity of any of the groups or their responses to amphetamine. On day 9, the antisense PNA-treated rats showed a statistically significant increase in their resting motility (P < 0.01). When these rats were challenged with amphetamine, motility of the saline-, scrambled PNA-, and mismatch PNA-treated animals showed increases of 31-, 36-, and 20-fold, respectively, while the antisense PNA-treated animals showed increases of only 3.4-fold (P < 0.01). ELISA results revealed a 32% decrease in striatal DAT in antisense PNA-treated rats compared with the saline, scrambled PNA, and mismatch PNA controls (P < 0.001). These results extend our previous findings that brain proteins can be knocked down in a specific manner by antisense molecules administered extracranially. Additionally, these results suggest some novel approaches for the treatment of diseases dependent upon the function of the dopamine transporter.
