Cannabidiol (CBD), a major cannabinoid found in Cannabis sativa L., has been used in the treatment of seizures associated with Lennox-Gastaut syndrome, Dravet syndrome, and tuberous sclerosis complex. Recently, concerns have been raised regarding the male reproductive toxicity of CBD in animal models, such as monkeys, rats, and mice. In our previous studies, we reported that CBD inhibited cell proliferation in both primary human Sertoli cells and mouse Sertoli TM4 cells. Transcriptomic analysis revealed that in primary human Sertoli cells CBD disrupted DNA replication, cell cycle, and DNA repair, ultimately causing cellular senescence. In this study, we further investigated the molecular changes induced by CBD in mouse Sertoli TM4 cells using RNA-sequencing analyses and compared the transcriptomic profile with that of primary human Sertoli cells. Our findings demonstrated that, unlike in primary human Sertoli cells, CBD did not induce cellular senescence but caused apoptosis in mouse Sertoli TM4 cells. Through transcriptomic data analysis in mouse Sertoli TM4 cells, immune and cellular stress responses were identified. Moreover, transcriptomic comparisons revealed major differences in molecular changes induced by CBD between mouse Sertoli TM4 and primary human Sertoli cells. This suggests that primary human Sertoli cells and mouse Sertoli cells may respond differently to CBD.
大麻二酚(CBD)是大麻中发现的一种主要大麻素,已被用于治疗与伦诺克斯 - 加斯托综合征、德雷维特综合征和结节性硬化症相关的癫痫发作。最近,人们对动物模型(如猴子、大鼠和小鼠)中CBD的雄性生殖毒性提出了担忧。在我们之前的研究中,我们报道了CBD抑制原代人支持细胞和小鼠支持细胞TM4的细胞增殖。转录组分析显示,在原代人支持细胞中,CBD破坏了DNA复制、细胞周期和DNA修复,最终导致细胞衰老。在本研究中,我们使用RNA测序分析进一步研究了CBD在小鼠支持细胞TM4中诱导的分子变化,并将转录组谱与原代人支持细胞的进行了比较。我们的研究结果表明,与原代人支持细胞不同,CBD在小鼠支持细胞TM4中不会诱导细胞衰老,但会导致细胞凋亡。通过对小鼠支持细胞TM4的转录组数据分析,确定了免疫和细胞应激反应。此外,转录组比较揭示了小鼠支持细胞TM4和原代人支持细胞中CBD诱导的分子变化的主要差异。这表明原代人支持细胞和小鼠支持细胞对CBD的反应可能不同。
