Cisplatin (CP), one of the most commonly used antitumor drugs in clinic, could induce reproductive and genetic toxicity. Traditional Chinese medicine believed that this side effect might be caused by the deficiency of both qi and blood. Panax notoginseng (Burk.) F. H. Chen (PN) is a traditional precious Chinese medicine for nourishing blood and hemostasis, which had the synergistic antitumor and reducing toxicity effects. However, the protective effect and mechanism of PN on CP-induced reproductive and genetic toxicity were still unknown.
This study was designed to illuminate the possible protective effect and mechanism of PN on CP-induced reproductive and genetic toxicity.
Network pharmacology was first applied to analyze the potential components and targets of PN against CP-induced reproductive and genetic toxicity. Then, the results of network pharmacology were validated in a mouse model of reproductive and genotoxicity induced by CP. Body weight, testis weight, epididymis weight, sperm count, sperm viability and sperm morphology were used to assess protective effects of PN on CP-induced reproductive toxicity. Tail moment in peripheral blood cells and micronucleus in bone marrow cells were used to assess protective effects of PN on CP-induced genetic toxicity. Finally, possible protective targets obtained from network pharmacology, including 8-hydroxy-2-deoxyguanosine (8-OHdG), malondialdehyde (MDA), total superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-Px), were experimentally validated by ELISA.
One hundred and nineteen components of PN and sixty-eight targets of reproductive/genetic toxicity were acquired and constituted as the component-target network. Network pharmacology analysis showed alleviating oxidative stress might play important role in therapeutic mechanism of PN. In verified experiments, PN significantly improved the decline of body weight, testis weight and epididymis weight, increased sperm count and viability, decreased abnormal sperm morphology rate induced by CP in mice. Moreover, PN also significantly decreased the tail moment in peripheral blood cells and micronucleus formation rate in bone marrow cells in CP-induced mice. Finally, not only the decrease of T-SOD and GSH-Px level but also the increase of 8-OHdG and MDA level in serum were restored under PN treatment.
Current study found that PN could improve CP-induced reproductive and genetic toxicity, which were probably attributed to alleviating oxidative stress. This finding provided the new perspective for understanding the therapeutic effect of PN on CP-induced reproductive and genetic toxicity and facilitating the clinical use of PN.
顺铂(CP)是临床最常用的抗肿瘤药物之一,可引起生殖和遗传毒性。中医认为,这种副作用可能是由于气血两虚引起的。三七(PN)是一种传统的珍贵中药,具有养血止血的作用,具有协同抗肿瘤和减毒作用。然而,PN 对 CP 诱导的生殖和遗传毒性的保护作用及其机制尚不清楚。
本研究旨在阐明 PN 对 CP 诱导的生殖和遗传毒性的可能保护作用及其机制。
首先应用网络药理学分析 PN 对 CP 诱导的生殖和遗传毒性的潜在成分和靶点。然后,在 CP 诱导的生殖和遗传毒性的小鼠模型中验证网络药理学的结果。体重、睾丸重量、附睾重量、精子计数、精子活力和精子形态用于评估 PN 对 CP 诱导的生殖毒性的保护作用。外周血红细胞的尾矩和骨髓细胞的微核用于评估 PN 对 CP 诱导的遗传毒性的保护作用。最后,通过酶联免疫吸附试验(ELISA)实验验证网络药理学获得的可能保护靶点,包括 8-羟基-2-脱氧鸟苷(8-OHdG)、丙二醛(MDA)、总超氧化物歧化酶(T-SOD)和谷胱甘肽过氧化物酶(GSH-Px)。
获得了 PN 的 119 种成分和生殖/遗传毒性的 68 种靶点,并构成了成分-靶点网络。网络药理学分析表明,缓解氧化应激可能在 PN 的治疗机制中发挥重要作用。在验证实验中,PN 显著改善了 CP 诱导的小鼠体重、睾丸重量和附睾重量下降、精子计数和活力增加、精子形态异常率下降。此外,PN 还显著降低了 CP 诱导的小鼠外周血红细胞的尾矩和骨髓细胞的微核形成率。最后,PN 治疗可恢复血清中 T-SOD 和 GSH-Px 水平的降低以及 8-OHdG 和 MDA 水平的升高。
本研究发现,PN 可改善 CP 诱导的生殖和遗传毒性,这可能归因于缓解氧化应激。这一发现为理解 PN 对 CP 诱导的生殖和遗传毒性的治疗作用提供了新的视角,并促进了 PN 在临床上的应用。
