JE:扶正消症方缓解大鼠肝癌的机制研究

2021-11-11 Vivi MedSci原创

扶正消症方治疗大鼠肝细胞癌的机制研究。

扶正消症方是由明代《温疫论》记载的著名汤剂三甲散衍生而来的中药,经过多年的临床应用,扶正消症方在肝硬化和肝细胞癌(HCC)治疗中取得了令人满意的疗效。然而其潜在机制在很大程度上仍是未知的。

近日在民族药物学杂志Journal of Ethnopharmacology发表的一项研究,采用二乙基亚硝胺(DEN)诱导大鼠肝细胞癌,并用扶正消症方治疗,旨在系统评价扶正消症方对大鼠HCC的干预作用,并深入阐明其调控机制。

该研究采用高效液相色谱法(HPLC)对制备的药剂成分进行分析。采用血生化(ALT、AST、ALP、GGT、DBIL、TBIL)、肝脏组织病理学、免疫组化(Ki67)评价干预效果。最后通过miRNA-Seq和mRNA-Seq研究扶正消症方对大鼠肝癌的调控机制,并通过qRT-PCR验证两种RNA的准确性。

该研究从扶正消症方中鉴定出9种潜在成分,其抗癌预测表明,几乎所有成分都显示出抗癌作用。

H&E染色显示模型组有明显的炎症浸润,肝细胞体积减少,治疗组肝脏病理明显改善。此外,Ki67免疫组织化学还表明,肝癌细胞的增殖和分化在治疗组低于模型组,治疗组Ki67 +细胞的比例明显低于模型组。扶正消症方干预后,大鼠ALT、AST、ALP、GGT、DBIL、TBIL等肝功能指标均明显改善。此外与低剂量治疗组相比,高剂量治疗组表现出最有效的抑制作用。综上,扶正消症方对大鼠肝癌有明显的缓解作用,且呈剂量依赖性

miRNA-Seq和mRNA-Seq检测提示,扶正消症方可通过激活PPAR信号通路、花生四烯酸代谢、胆汁分泌等途径促进脂质相关代谢,提高抗炎能力。

QRT-PCR结果显示,在4个DEmiRs中,有3个与miRNA-Seq表达一致,所选择的6种mRNA均表现出与mRNA-Seq相同的表达趋势。qRT-PCR和RNA- Seq均显示该基因的表达趋势呈剂量依赖性,这与上述结果一致。

为了进一步证实扶正消症方对脂类相关代谢和炎症反应的调节作用,该研究检测了血清中4种脂类相关指标的含量(TC、TG、LDL-C、HDL-C)和4种细胞因子的表达水平(IL-2、IL-6、IL-10、IFN-γ)。扶正消症方干预后,TC和TG从模型组到高剂量治疗组均呈下降趋势,LDL-C和HDL-C含量均呈上升趋势。此外4种细胞因子指标均有不同程度的缓解。

综上所述,该研究结果提示,扶正消症方对肝细胞癌有明显的缓解作用,可能通过调节脂质相关代谢和增强抗炎能力来抑制肝癌的进展。但需要指出的是,其作用机制仍需进一步研究。
