Figure 1. Co-expression of HER4 and TTF-1 decreases lung epithelial cell viability under control and NRG treatment conditions.
Lung epithelial cell viability was measured in MLE-12 cells, transfected with full-length ErbB4 (HER4), TTF-1 or HER4, and TTF-1 (HER4/TTF-1) under control conditions (black bars) and after 24 hours NRG treatment (grey bars). Results were compared to EGFP -transfected control cells (A) or NRG-treated EGFP-transfected cells (B). *P ≤0.01, **P ≤0.001, n= 10-11.
