Effects of chemotherapeutic drugs on the growth of MIA-PaCa-2 + WT-GSK-3β, MIA-PaCa-2 + KD-GSK-3β and MIA-PaCa-2 + pLXSN cells. The effects of doxorubicin (Panel (A)), daunorubicin (Panel (B)), mitoxantrone (Panel (C)), and etoposide (Panel (D)) on MIA-PaCa-2 + WT-GSK-3β (solid red boxes), MIA-PaCa-2 + KD-GSK-3β (solid blue triangles) and MIA-PaCa-2 + pLXSN Cells (solid green circles) were examined by MTT analysis. The MIA-PaCa-2 + WT-GSK-3β, MIA-PaCa-2 + KD-GSK-3β, and MIA-PaCa-2 + pLXSN cells in each panel were all examined at the same time period. These experiments were repeated 4 times and similar results were obtained. Statistical analyses were performed via the Student’s T test on the means and standard deviations of various treatment groups. *** p < 0.0001, ** p < 0.005, and * p < 0.05.
