Fig. 10. FOXA2 inhibits Muc5ac transcription. H292 cells were transfected
with promoter plasmid pGL3-MUC5AC-luc and increasing amounts of the expression
plasmid pRC-CMV-FOXA2. MUC5AC promoter activity was determined by the relative
luciferase activity normalized to ß-galactosidase activity. As a positive
control, all trans-retinoic acid (3 µgml-1) was added to induce
MUC5AC expression. Plasmid pRC-CMV was used as empty vector control.
*P<0.05 versus control (ANOVA).
