Exploring the anti-glioma mechanism of the active components of Cortex Periplocae based on network pharmacology and iTRAQ proteomics in vitro

Hierarchical clustering analysis of candidate proteins was illustrated in heat map, which showed obvious differences between CP-induced cells and controls (Fig. 6). Each column is a sample and each rowindicates a differentially expressed protein. Log values (log₂expression) of significantly differentially expressed proteins in different samples are displayed in heat maps in different colors. GreenandRedrepresent up-regulation and down-regulation, respectively. The gray part represents no quantitative information of the proteins. T1, T2 and T3 means the CP-treated U251 cells group and C2, C2 and C3 means control group (n=3).
