TITLE: | Pharmacodynamic substances and mechanism of Chelidonii Herba-Corydalis Rhizoma against estrogen receptor-positive breast cancer |
摘要: | 目的 分析白屈菜-元胡药对(CHCR)的主要成分,预测其抗雌激素受体(ER)阳性乳腺癌的药效物质、潜在作用靶点及通路并进行验证。方法采用超高效液相色谱-四极杆飞行时间串联质谱(UPLC-Q-TOF-MS/MS)技术对CHCR乙醇提取物的成分进行分析;对所得成分进行网络药理学分析,构建CHCR“活性成分-靶点-通路”网络,并对富集通路进行体外细胞实验验证。结果共鉴定出58个化学成分,含生物碱57个、有机酸1个。网络药理学共筛选出活性成分38个“,成分-疾病”交集靶点的蛋白质-蛋白质互作网络中有核心靶点38个;得基因本体条目258个,京都基因与基因组百科全书通路137条,主要包括雌激素信号通路、磷脂酰肌醇3激酶/蛋白激酶B(PI3K/Akt)信号通路等。验证实验结果显示,CHCR作用于MCF-7细胞的半数抑制浓度为693μg/mL;150、300、600μg/mL的CHCR可显著降低磷酸化PI3K、磷酸化Akt、ERα蛋白和ESR1mRNA的表达水平(P<0.01)。结论CHCR抗ER阳性乳腺癌的作用可能与调控ER、PI3K/Akt通路有关,具有多成分、多靶点的作用特点。 |
ABSTRACT: | OBJECTIVE To analyze the main components of Chelidonii Herba-Corydalis Rhizoma (CHCR), and to predict pharmacodynamic substances against estrogen receptor (ER) -positive breast cancer and their potential targets and signaling pathways, followed by verifying experiments. METHODS The ethanol extract of CHCR was analyzed by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS). The network pharmacology analysis was performed for the screened components. The network diagram of CHCR “active components-target-pathway” was constructed, and the enrichment pathway in vitro was validated. RESULTS A total of 58 chemical components were identified, including 57 alkaloids and 1 organic acid. A total of 38 active ingredients were screened from the network pharmacology, and 38 core targets were found in the protein-protein interaction network of “component-disease” intersection targets; 258 gene ontology entries and 137 Kyoto encyclopedia of genes and genomics pathways were obtained, mainly including estrogen signal pathway, phosphatidylinositol-3-kinase/protein kinase B (PI3K/Akt) signal pathway, etc. The results of validation test showed that the median inhibitory concentration of CHCR to MCF-7 cells was 693 μg/mL; 150, 300, 600 μg/mL CHCR could significantly reduce the expressions of phosphorylated PI3K, phosphorylated Akt, ERα protein and ESR1 mRNA (P<0.01). CONCLUSIONS The anti-ER-positive breast cancer effect of CHCR may be related to the regulation of ER and PI3K/Akt pathways, which has the characteristics of multi-component and multi-target effects. |
