Coptidis rhizoma and evodiae fructus against lipid droplet deposition in nonalcoholic fatty liver disease-related liver cancer by AKT

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in the world. NAFLD has become one of the major factors contributing to hepatocellular carcinoma (HCC) development. However, there are no clear targets and therapeutic drugs for NAFLD-related liver cancer. This study explored the active compounds, target and mechanism of coptidis rhizoma and evodiae fructus in the treatment of NAFLD-related liver cancer based on the network pharmacology and experimental verification. There were 455 intersection targets of NAFLD-related liver cancer, and 65 drug-disease common targets. AKT1 has the highest degree, indicating that it may be a key target of coptidis rhizoma and evodiae fructus in the treatment of NAFLD-related liver cancer. The expression level of AKT1 was high in high-risk group, and the overall survival rate was lower than that in low-risk group. After oleic acid induction, p-AKT expression and lipid droplet deposition were promoted in HepG2 cells. Quercetin and resveratrol reduced lipid droplet deposition in vivo. Moreover, quercetin inhibited p-AKT expression, resveratrol both reduced the expression of p-AKT and AKT. The overall findings suggested that quercetin inhibited AKT in the treatment of NAFLD-related liver cancer.     

基于网络药理学-分子对接技术探讨泽泻 抗炎作用的分子机制

摘要：目的：应用网络药理学方法及分子对接技术，探讨泽泻发挥抗炎作用的活性成分及其对应靶点和相关通路。方法：通过TCMSP筛选出泽泻的活性成分，运用SwissTarget Prediction 数据库预测活性成分相关靶标，同时采用GeneCards数据库得到炎症相关靶点，再将获得的活性成分靶点和炎症靶点导入VENNY2.1得到药物治疗疾病的潜在靶点；再运用STRING数据库、Cytoscape3.7.1软件构建简化后的药物治疗疾病的靶蛋白互作图（PPI）并筛选关键靶点。利用DAVID数据库对关键靶点进行GO功能富集分析和KEGG信号通路分析，再用Cytoscape3.7.1软件构建“化合物-靶点-通路”图并筛选核心成分与核心靶点。最后运用AutoDock Vina和Pymol将核心成分与核心靶点进行分子对接。结果：获得10个药物活性成分，得到相关潜在靶点284个，疾病潜在靶点11414个，药物治疗疾病的相关靶点260个，有SRC、HSP90AA1、PIK3CA、MAPK1、AKT1、LCK、FYN、JAK1、PLCG1、JAK1等关键靶点58个；涉及PI3K-Akt信号通路、ErbB信号通路、FoxO信号通路等133条通路。结论：泽泻发挥抗炎的作用机制可能是一方面通过调控PIK3、AKT、m-TOR等相关蛋白，激活PI3K-Akt信号通路，从而抑制细胞凋亡；另一方面可能通过调控EGFR相关蛋白，介导ErbB信号通路，从而干预炎症细胞生长。本研究基于网络药理学方法和分子对接技术，阐释了泽泻通过多种成分、多靶点、多信号通路发挥抗炎作用与机制，为该药的进一步研究提供了有益参考和科学依据。     

复方菝葜颗粒对A549细胞生长状态的影响

目的 观察复方菝葜颗粒对A549细胞生长状态的影响。方法 雄性SD大鼠30只，随机分为两组，每组15只。一组灌服复方菝葜颗粒，2次/d，另一组灌服等剂量蒸馏水，第6次灌胃后2h提取血清。A549细胞株随机分为中药实验组、西药对照组和正常对照组，分别加入10％含药血清、顺铂3μg/mL和10％SD大鼠血清进行培养，分别在培养0 h、24 h、48 h和72 h时进行细胞计数，绘制A549细胞的生长曲线。结果 培养0h和24h时的3组细胞数无明显差异(P<0.01)；培养48 h后中药实验组和西药对照组的细胞数均有所增长，但明显少于正常对照组，相比差异有显著性(P<0.01)，中药实验组和西药对照组的细胞数无明显差异(P>0.05)；培养72h后，正常对照组明显高于中药实验组和西药对照组，中药实验组和西药对照组比较无明显差异。结论 复方菝葜颗粒能够抑制A549细胞的增长速度。
