Combination of TNO155 and everolimus are synergistic in OSCC lines. (A) Matrix of cell viability across various combinations of TNO155 (SHP2 inhibitor) and everolimus (mTOR inhibitor) in BICR10 and PE/CA-PJ15, suggesting a synergistic effect. (B) Plot of combination index (CI) against fraction affected (Fa) of TNO155 (0.02 μM, 0.1 μM, 0.48 μM, 2.4 μM and 12 μM) and everolimus (0.0003 μM and 0.006 μM) combinations in BICR10 and PE/CA-PJ15. Only doses that are lower than single-agent IC50 is plotted here. (C) Colony formation assays at various combinations of TNO155 and everolimus showing the synergistic effect of the combinations. (D) Western blot showing the effect of the TNO155 and everolimus combinations on the phosphorylation levels of key downstream markers.
