Fig. 3. Heteromultimerization of EGFR and EphA2 in the presence of ligands and PLC drugs.
(A) PIE-FCCS data for EGFR-mCH and EphA2-eGFP coexpressed in COS-7 cells. Data were recorded before treatment (white), after the addition of EGF (gray) or EA1 (orange), and after treatment with the PLC inhibitor U73122 (blue) or with the PLC activator 3M3FBS (green). (B) Diffusion coefficients of EGFR-mCH after treatment with ligands and PLC-regulating drugs. (C) Diffusion coefficients of EphA2-eGFP after treatment with ligands and PLC-regulating drugs. (D) Representative epifluorescence images from each set of experiments. One-way ANOVA tests with uncorrected Fisher’s LSD post hoc tests show the individual P values (*P < 0.0259, **P < 0.003, and ****P < 0.0001). Diffusion coefficient data are represented as mean values ± SEM.
