摘要

背景断奶后的社会隔离(SI)会降低啮齿动物模型的交际能力、基因表达(包括内侧前额叶皮层(mPFC)中的髓鞘基因),并改变微生物组的组成。据报道,高丽红参(KRG)及其主要人参皂苷 Rb1 会影响髓鞘的形成和肠道代谢物。然而,它们对断奶后 SI 的影响尚未得到研究。方法C57BL/6J小鼠断奶后(P21-P35)在SI或常规环境(RE)下给水或KRG(150、400 mg/kg)或Rb1(0.1 mg/kg),持续2周。结果与 RE 相比,SI 会降低小鼠的交际能力;但在 SI 环境下,KRG(400 mg/kg)和 Rb1 能显著恢复小鼠的交际能力。在 mPFC 中,与 RE 条件相比,SI 条件下小鼠髓鞘、神经递质和氧化应激相关基因的表达明显减少。在SI条件下,KRG和Rb1恢复了mPFC中几个基因表达的改变。在肠道代谢组学中,在3027个检测到的代谢物中,有313个代谢物被确定为重要代谢物。结论KRG和Rb1至少可以部分恢复断奶后两周SI引起的交际能力、mPFC基因表达水平和肠道代谢物的改变。

Korean Red Ginseng and Rb1 restore altered social interaction, gene expressions in the medial prefrontal cortex, and gut metabolites under post-weaning social isolation in mice

Background

Post-weaning social isolation (SI) reduces sociability, gene expressions including myelin genes in the medial prefrontal cortex (mPFC), and alters microbiome compositions in rodent models. Korean Red Ginseng (KRG) and its major ginsenoside Rb1 have been reported to affect myelin formation and gut metabolites. However, their effects under post-weaning SI have not been investigated. This study investigated the effects of KRG and Rb1 on sociability, gene expressions in the mPFC, and gut metabolites under post-weaning SI.

Methods

C57BL/6J mice were administered with water or KRG (150, 400 mg/kg) or Rb1 (0.1 mg/kg) under SI or regular environment (RE) for 2 weeks during the post-weaning period (P21–P35). After this period, mice underwent a sociability test, and then brains and ceca were collected for qPCR/immunohistochemistry and non-targeted metabolomics, respectively.

Results

SI reduced sociability compared to RE; however, KRG (400 mg/kg) and Rb1 significantly restored sociability under SI. In the mPFC, expressions of genes related to myelin, neurotransmitter, and oxidative stress were significantly reduced in mice under SI compared to RE conditions. Under SI, KRG and Rb1 recovered the altered expressions of several genes in the mPFC. In gut metabolomics, 313 metabolites were identified as significant among 3027 detected metabolites. Among the significantly changed metabolites in SI, some were recovered by KRG or Rb1, including metabolites related to stress axis, inflammation, and DNA damage.

Conclusion

Altered sociability, gene expression levels in the mPFC, and gut metabolites induced by two weeks of post-weaning SI were at least partially recovered by KRG and Rb1.

期刊介绍: Journal of Ginseng Research (JGR) is an official, open access journal of the Korean Society of Ginseng and is the only international journal publishing scholarly reports on ginseng research in the world. The journal is a bimonthly peer-reviewed publication featuring high-quality studies related to basic, pre-clinical, and clinical researches on ginseng to reflect recent progresses in ginseng research. JGR publishes papers, either experimental or theoretical, that advance our understanding of ginseng science, including plant sciences, biology, chemistry, pharmacology, toxicology, pharmacokinetics, veterinary medicine, biochemistry, manufacture, and clinical study of ginseng since 1976. It also includes the new paradigm of integrative research, covering alternative medicinal approaches. Article types considered for publication include review articles, original research articles, and brief reports. JGR helps researchers to understand mechanisms for traditional efficacy of ginseng and to put their clinical evidence together. It provides balanced information on basic science and clinical applications to researchers, manufacturers, practitioners, teachers, scholars, and medical doctors.
