The widespread recreational use of synthetic cannabinoids (SCs) has become a serious health issue. Reports of life-threatening intoxications related to SC consumption have markedly increased in recent years, including neurotoxicity, cardiotoxicity, nephrotoxicity, and hepatotoxicity. We investigated the impact of acute administration of the synthetic cannabinoid XLR-11 (3 mg/kg, i.p. for 5 consecutive days) on the liver in BALB/c mouse animal model. Using real-time quantitative RT-PCR, MDA assay, and TUNEL assay, we found consistent up-regulation of a variety of genes involved in oxidative stress (NOX2, NOX4, and iNOS), inflammation (TNF-α, IL-1β, IL-6), and apoptosis (Bax) in the liver of XLR-11 treated mice compared to control mice. These finding were supported with an elevation of MDA levels and TUNEL positive cells in the liver of XLR-11 treated mice which further confirm increased oxidative stress and apoptosis, respectively. Histopathological analysis of the liver of XLR-11 treated mice confirmed pronounced hepatic necrosis associated with inflammatory cell infiltration. Furthermore, elevated ALT and AST serum levels were also identified in XLR-11 treated mice indicating possible liver damage. Overall, SC-induced hepatotoxicity seems to be mainly mediated by activated oxidative stress and inflammatory processes in the liver, but the specific mechanisms involved require further investigations. However, the present study shed light on the potential deleterious role of acute administration of SCs in the progression to acute hepatic injury which enhances our understanding of the adverse effect of SC consumption.
合成大麻素(SCs)的广泛娱乐性使用已成为一个严重的健康问题。近年来,与食用SCs相关的危及生命的中毒报告显著增加,包括神经毒性、心脏毒性、肾毒性和肝毒性。我们在BALB/c小鼠动物模型中研究了急性给予合成大麻素XLR-11(3毫克/千克,腹腔注射,连续5天)对肝脏的影响。通过实时定量逆转录-聚合酶链反应、丙二醛(MDA)测定和末端脱氧核苷酸转移酶介导的缺口末端标记(TUNEL)测定,我们发现与对照小鼠相比,XLR-11处理的小鼠肝脏中多种参与氧化应激(NOX2、NOX4和诱导型一氧化氮合酶)、炎症(肿瘤坏死因子-α、白细胞介素-1β、白细胞介素-6)和凋亡(Bax)的基因持续上调。这些发现得到了XLR-11处理的小鼠肝脏中MDA水平升高和TUNEL阳性细胞增加的支持,这分别进一步证实了氧化应激和凋亡的增加。对XLR-11处理的小鼠肝脏进行组织病理学分析证实存在明显的肝坏死并伴有炎性细胞浸润。此外,在XLR-11处理的小鼠中还发现血清谷丙转氨酶(ALT)和谷草转氨酶(AST)水平升高,表明可能存在肝损伤。总体而言,SCs诱导的肝毒性似乎主要由肝脏中激活的氧化应激和炎症过程介导,但具体机制仍需进一步研究。然而,本研究揭示了急性给予SCs在急性肝损伤进展中的潜在有害作用,这增强了我们对食用SCs不良反应的理解。
