Ponatinib combined with rapamycin enhances AKT (protein kinase B) suppression and ERK1/2 (extracellular signal-regulated kinase) activity. A, Phosphorylation changes of 45 kinases in human umbilical vein endothelial cell (HUVEC)-TIE2-L914F (L914F) relative to HUVEC-TIE2-wild type (WT). B, Immunoblot analysis of HUVEC nontransfected (NT), HUVEC-TIE2-WT, and HUVEC-TIE2-L914F (L914F) with indicated antibodies. C, Immunoblot analysis of HUVEC-TIE2-L914F with listed antibodies. Cells were treated with DMSO (Control), 100 nmol/L ponatinib, 10 nmol/L rapamycin, or combination for 48 h. Immunoblot bands were quantified, data expressed as mean±SD, 1-way ANOVA for multiple comparisons (n=3–4 independent experiments). D, Immunoblot analysis of HUVEC-TIE2-L914F treated with shRNA for c-ABL/ARG or with scrambled sequence (sh Scrambled). E, Western blotting analysis of HUVEC-TIE2-L914F with indicated antibodies. Cells were treated with DMSO (Control), 100 nmol/L ponatinib or 10 µmol/L Wortmannin for 1 h.
