MEK, PI3-K or p38MAPK inhibition does not affect reovirus cytotoxicity. Cal27 cells were inhibited for 2 hrs with 2 μM (PD2) or 10 μM (PD10) PD184352, 10 μM U0126 (U), 10 μM SB202190 (SB), 10 μM LY294003 (LY) or 1 μM wortmannin (wort). Monolayers were then either lysed, resolved on 8% Precise Protein Gels (MAPK) or 10% NuPage Novex Bis Tris gels (PI3-K) and probed for total ERK1/2, phosho-Thr202 ERK1/2, total AKT, phospho-Ser473 AKT and GAPDH or β-actin as loading controls, or infected with reovirus at 1.2×1010 TCID50/ml (PD, SB and LY) or 7.8×108 TCID50/ml (wort) and assayed for cell survival by MTT. p38MAPK target knock-down was confirmed by ELISA. Reovirus was diluted at 1:4000 for 50% cell kill. A, B. MAPK inhibition. C, D. p38MAPK inhibition. E, F. PI3K inhibition. Means are calculated from at least 3 independent experiments and error bars represent SEMs.
