    • Methamphetamine is a highly addictive psychostimulant that causes profound damage to the brain and other body organs. Post mortem studies of human tissues have linked the use of this drug to diseases associated with aging, such as coronary atherosclerosis, but the molecular mechanism underlying these findings remains unknown. We report now that methamphetamine accelerates cellular senescence in vitro and activates transcription of genes involved in cell-cycle control and inflammation in vivo by stimulating production of the sphingolipid messenger ceramide. This pathogenic cascade is triggered by reactive oxygen species, generated through methamphetamine metabolism via cytochrome Pas0-2D6, which recruit nuclear factor (NF)-KB to induce expression of enzymes in the de novo pathway of ceramide biosynthesis. Inhibitors of ceramide formation prevent methamphetamine-induced senescence and attenuate systemic inflammation and health deterioration in rats self- administering the drug. The results support therapeutic approaches to reduce the adverse consequences of methamphetamine abuse and improve effectiveness of treatments.
    • 甲基苯丙胺是一种高度上瘾的精神兴奋剂,会对大脑和其他身体器官造成深刻的伤害。 人类组织的死后研究已经将这种药物与衰老相关的疾病(如冠状动脉粥样硬化)联系在一起,但是这些发现的分子机制仍然是未知的。 我们现在报告说,甲基苯丙胺在体外加速细胞衰老,并通过刺激神经鞘脂信使神经酰胺的产生来激活参与细胞周期控制和体内炎症的基因的转录。 这种致病性级联由活性氧引发,通过细胞色素Pas0-2D6通过甲基苯丙胺代谢产生,其募集核因子(NF)-KB以诱导神经酰胺生物合成的从头途径中的酶的表达。 神经酰胺形成抑制剂可以预防甲基苯丙胺诱导的衰老并减轻大鼠自身给药的全身炎症和健康恶化。 结果支持减少甲基苯丙胺滥用的不良后果并提高治疗效果的治疗方法。
