FIGURE 3.
Western blot analysis of oridonin on EGFR pathway proteins. The effects of oridonin on phosphorylation of ΔEGFR, STAT3, and Akt were evaluated. Bands were normalized to β-actin in order to obtain numerical values (mean ± SEM of three independent experiments). Total EGFR, STAT3, and Akt protein levels are also shown. A representative blot is shown and statistical analysis was done by paired Student’s t-test. ∗∗p < 0.01, ∗p < 0.05.
