目的
2
该研究旨在基于miRNA差异性探讨化毒三阴方对气虚质三阴乳腺癌(TNBC)患者磷脂酰肌醇3-激酶/蛋白激酶B/核转录因子
-κ
B(PI3K/Akt/NF-
κ
B)信号通路的调控作用。
方法
2
基于前期研究成果及利用生信分析方法,预测气虚质与平和质患者差异表达miRNA调控的靶基因,与TNBC靶基因取交集,并将交集靶基因进行京都基因和基因组百科全书(KEGG)通路富集和蛋白质-蛋白质相互作用(PPI)网络分析,分析其差异表达miRNA调控TNBC关键通路及靶基因。纳入完成西医标准治疗后气虚质TNBC患者,予化毒三阴方干预3年,收集服药前后患者外周血,检测其服药前后关键通路上基因的表达情况。
结果
2
气虚质与平和质差异表达的miRNA共有49个,上调16个,下调33个,调控TNBC共1 445个靶基因,PPI和KEGG通路富集分析显示,关键基因主要有肿瘤蛋白p53(TP53),蛋白激酶B1(Akt1),表皮生长因子受体(EGFR),丝裂原活化蛋白激酶3(MAPK3),血管内皮生长因子A(VEGFA),肿瘤坏死因子(TNF)等,关键通路有PI3K/Akt,丝裂原活化蛋白激酶(MAPK),RAS信号通路等。共纳入11例气虚质TNBC患者,与服药前相比,服药后患者PI3K/Akt信号通路上NF-
κ
B1,Akt1表达下调,编码PI3K基因(PIK3CA),B细胞淋巴瘤-xL(Bcl-xL)表达上调。其中治疗前后NF-κB1,Akt1表达差异具有统计学意义。
结论
2
化毒三阴方可调控气虚质TNBC患者的PI3K/Akt/NF-
κ
B信号通路上的基因表达,使NF-
κ
B1,Akt1表达下调,PIK3CA,Bcl-xL表达上调。
Objective
2
To explore the regulatory effect of Huadu Sanyinfang on phosphatidylinositol 3 kinase(PI3K)/protein kinase B(Akt)/transcription factor nuclear factor-
κ
B (NF-
κ
B) in triple-negative breast cancer (TNBC) patients with qi-deficiency constitution based on the differential expression of miRNA.
Method
2
Based on previous research results, this study conducted the bioinformatics analysis to predict the target genes responsible for regulating the differential expression of miRNA between patients with qi-deficiency constitution and those with moderate constitution, which were intersected with TNBC target genes. The resulting intersection targets were then subjected to Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and protein-protein interaction (PPI) network analysis to obtain the key pathways and target genes for differentially expressed miRNA in regulating TNBC. TNBC patients with Qi-deficiency constitution were treated with Huadu Sanyinfang for three years after they completed the standard Western medical treatment. The peripheral blood of the patients was sampled before and after medication for detecting gene expression in the key pathways.
Result
2
The comparison between patients with Qi-deficiency constitution and those with moderate constitution revealed 49 differentially expressed miRNAs (16 up-regulated and 33 down-regulated), which regulated 1 445 TNBC target genes. As demonstrated by PPI and KEGG pathway enrichment analysis, the key genes were mainly tumor protein p53 (TP53), Akt1, epidermal growth factor receptor (EGFR), mitogen-activated protein kinase 3 (MAPK3), vascular endothelial growth factor A (VEGRA), and tumor necrosis factor (TNF). The key pathways included PI3K/Akt, MAPK, and RAS signaling pathways. A total of 11 TNBC patients with qi-deficiency constitution were enrolled. Compared with the situations before treatment, the expression levels of p105 subunit of NF-κB (NF-
κ
B1) and Akt1 in the PI3K/Akt signaling pathway were down-regulated after medication, while the levels of catalytic subunit alpha of PI3K (PIK3CA) and B-cell lymphoma-xL (Bcl-xL) were up-regulated. The differences in NF-
κ
B1 and Akt1 expression were statistically significant.
Conclusion
2
Huadu Sanyinfang is able to affect the gene expression of PI3K/Akt/NF-
κ
B signaling pathway in TNBC patients with Qi-deficiency constitution. Specifically, it down-regulates NF-
κ
B1 and Akt1 expression and up-regulates PIK3CA and Bcl-xL.
