H Control or LAPTM4B‐overexpressing MDA‐MB‐231 cells were starved and then stimulated with 100 ng/ml EGF for 1-4 h. EGFR degradation and signaling were analyzed by Western blot. Specific antibodies recognizing pEGFR (Y1068) and pAKT (S473) were used.I-K Quantification for the levels of EGFR (I) and pEGFR (J) normalized to actin and pAKT (K) normalized to AKT in control or LAPTM4B‐overexpressing cells (mean ± SD, n = 3).
