Combination of NVP-AEW541 and lapatinib cooperatively inhibits the growth of NVP-AEW541 resistant murine rhabdomyosarcoma primary cell cultures with Igf1r/Her2 complexes. Cell viability assay for Naïve, untreated (U20325; A) and NVP-AEW541 innately resistant mouse rhabdomyosarcoma primary culture (U44676; B) treated with varying concentrations of NVP-AEW541, lapatinib, or a combination of both. Naïve cells (U20325) were sensitive to NVP-AEW541, but lapatinib had no cooperativity. In contrast, NVP-AEW541 at moderate doses increased cell growth in resistant cell cultures (U44676). However, this paradoxical effect was reduced by the addition of lapatinib, although lapatinib treatment alone had very little effect. C, the NVP-AEW541 resistant primary tumor cell line (U44676) was treated with DMSO, 5 μmol/L lapatinib, 5 μmol/L NVP-AEW541, and a combination of 5 μmol/L NVP-AEW541+lapatinib for 25 minutes and Western blot analysis was done on lysates for p-Igf1r and p-Her2. |
