Effect of leptin on EGFR transactivation in cardiac myofibroblasts. EGFR phosphorylation in either Tyr864 (a) or Tyr 1173 (b) were analyzed by flow cytometry analysis in cardiac myofibroblasts stimulated with leptin (100 ng/mL) for indicated time intervals. Bar graphs represent the mean ± SEM of 3 assays.
