Triiodothyronine Represses MUC5AC Expression by Antagonizing Sp1 Binding to Its Promoter in Human Bronchial Epithelial HBE16 Cells
Figure 2
T3 inhibits the transcription of MUC5AC in HBE16 cells. The luciferase activity was determined as described in Materials and Methods. Control group: different MUC5AC promoter plasmids in the absence of T3; experimental group: different MUC5AC promoter plasmids in the presence of T3. versus pGL3-basic control group; versus pGL3-basic control group; # versus the same promoter control group; ## versus the same promoter control group.
