Fig. 1. Correlation between CAR mRNA transcript levels and transepithelial resistance in human airway epithelia from eight different organ donors. (A) Relationship between CAR transcript levels as determined by array analysis and transepithelial resistance measured by Ussing chamber studies in well-differentiated primary human airway epithelia cultures grown at the air-liquid interface (R²=0.8037, n=8). (B) No correlation was evident between ß-Actin transcript levels and transepithelial resistance (R²=9x10^–5, n=8).
