Baicalein Inhibits Orthotopic Human Non-Small Cell Lung Cancer Xenografts via Src/Id1 Pathway
Figure 3
Baicalein inhibited Id1 expression of A549 orthotopic NSCLC xenografts. (a) Western blot analysis was performed to determine the Id1 protein. Two representative mice were presented. (b) Immunohistochemical analysis for Id1 of normal lung or xenograft tissues. The total number of Id1 positive cells (brown-stained nuclei, regardless of staining intensity, were counted as positive) in three random microscopic fields was counted by Image-Pro Plus 6.0. Data was shown as mean ± SEM (P< 0.01, P< 0.0001 compared with the control group).
