目的:探讨夏枯草消瘤合剂通过改变巨噬细胞M2转化途径增强安罗替尼对非小细胞肺癌(NSCLC)皮下移植瘤模型小鼠抑瘤的作用与机制.方法:24只SPF级雄性BALB/cNude裸小鼠随机分为生理盐水组、安罗替尼组、夏枯草消瘤合剂联合安罗替尼组,每组8只,皮下注射NCI-H1975细胞建立皮下移植瘤模型,造模成功后,各组灌胃给予相应药物.测量瘤体大小,采用转录组测序寻找差异基因,RT-qPCR法检测验证差异基因相关的巨噬细胞炎症因子mRNA表达水平.结果:与生理盐水组比较,夏枯草消瘤合剂联合安罗替尼组能显著抑制瘤体体积增长(P＜0.05),且疗效优于安罗替尼组(P＜0.05).夏枯草消瘤合剂联合安罗替尼组及安罗替尼组治疗的抑瘤率分别为58.6％、43.4％.与安罗替尼组比较,夏枯草消瘤合剂联合安罗替尼组瘤体中检测到589个显著差异的基因,其中287个基因上调,302个基因下调,使用TIMER 2.0利用IRIS数据库从RNA-seq数据中提取的免疫细胞表达特征,发现夏枯草消瘤合剂联合安罗替尼组与安罗替尼组主要差异免疫细胞为巨噬细胞比例增高.RT-qPCR验证显示,与生理盐水组、安罗替尼组比较,夏枯草消瘤合剂联合安罗替尼组能显著提高M1巨噬细胞相关CCL2、CCL3、IL-12、IL-1b促炎因子mRNA表达,下调M2相关抗炎细胞因子IL-10 mRNA的表达(P＜0.01).结论:夏枯草消瘤合剂联合安罗替尼治疗能增强抑制NSCLC细胞皮下移植瘤增殖,其机制可能与促进M1表型巨噬细胞极化,M2表型巨噬细胞去极化有关.
Mechanism of Xiakucao Xiaoliu Heji combined with Anlotinib in inhibiting subcutaneous tumor growth in lung cancer
Objective:To investigate how the Xiakucao Xiaoliu Heji enhances the antitumor effects of Anlotinib in a subcutaneous tumor model of non-small cell lung cancer(NSCLC)by modulating the M2 macrophage transformation pathway.Methods:Twenty-four SPF male BALB/cNude mice were randomly divided into three groups:the saline group,the Anlotinib group,and the Xiakucao Xiaoliu Heji combined with Anlotinib group,with 8 mice in each group.Subcutaneous tumor models were established by injecting NCI-H1975 cells,and after successful modeling,each group was administered the corresponding drugs.Tumor size was measured,and differential genes were identified using transcriptome sequencing.The mRNA expression levels of macrophage inflammatory factors related to differential genes were validated using RT-qPCR.Results:Compared with the saline group,the Xiakucao Xiaoliu Heji combined with Anlotinib group significantly inhibited tumor volume growth(P＜0.05),and it was more effective than Anlotinib group(P＜0.05).The tumor inhibition rates for the Xiakucao Xiaoliu Heji combined with Anlotinib group and Anlotinib group were 58.6％and 43.4％,respectively.Compared with the Anlotinib group,Xiakucao Xiaoliu Heji combined with Anlotinib group showed 589 significantly different genes in the tumor,with 287 upregulated genes and 302 downregulated genes.Using TIMER 2.0 and IRIS database,immune cell expression characteristics extracted from RNA-seq data revealed an increase in the proportion of macrophages in the Xiakucao Xiaoliu Heji combined with Anlotinib group compared to the Anlotinib group.RT-qPCR validation showed that the Xiakucao Xiaoliu Heji combined with Anlotinib group significantly increased the mRNA expression of pro-inflammatory factors related to M1 macrophages,such as CCL2,CCL3,IL-12,and IL-1b,while downregulating the expression of anti-inflammatory factors related to M2 macrophages,such as IL-10 mRNA compared with the saline group and Anlotinib group(P＜0.01).Conclusion:Combined treatment with the Xiakucao Xiaoliu Heji and Anlotinib enhances the inhibition of subcutaneous tumor growth in NSCLC,possibly through the promotion of M1 macrophage polarization and M2 macrophage depolarization.
