Figure 3. Effect of afatinib on the intracellular accumulation of Dox and Rho123 in S1 and S1-MI-80 cells.

The accumulation of Dox (A, C) and Rho 123 (B, D) was measured by flow cytometry as described in Materials and Methods. All of these experiments were repeated at least thrice. Data represent Mean ± SD. *p < 0.05, **p < 0.01.
