Figure 7. The Akt inhibitor, but not Src inhibitor, dramatically potentiates lapatinib-induced apoptosis in trastzumab-resistant breast cancer cells.

Figure 7

SKBR3-Pool2 and BT474-HR20 cells untreated or treated with lapatinib (0.1 μmol/L) or lapatinib combined with Akt/Src inhibitor (Lap+Akti/Lap+Srci) for 24 hr were subjected to the following experiments. A & B. Western blot analyses of PARP (F-PARP, full length PARP; C-PARP, cleaved PARP), caspase-8 (F-Casp-8, full length caspase-8; C-Casp-8, cleaved caspase-8), caspase-3 (F-Casp-3, full length caspase-3; C-Casp-3, cleaved caspase-3), or β-actin (A); or a specific apoptosis ELISA (B).
