Effects of ERK inhibition on the expression of CSC markers (CD44 and Oct ¾), β-catenin, and EMT markers (E-cadherin and N-cadherin) in both p-MDA-MB-231 and RT-R-MDA-MB-231 cells. (A) Western blot analysis of CSC markers (CD44 and Oct ¾), β-catenin, and EMT markers (E-cadherin and N-cadherin). (B) Densitometry analysis of the data in Western blot analysis by ImageJ software. The values were normalized against β-actin, and they are represented as mean ± standard deviation (SD) (n = 5). ** p < 0.01; *** p < 0.005 vs. the control group.
