Promoter reporter assay of predicted C/EBPA and SREBP targets in transient transfection of MLE-15 cells. Schematic representation of the ≥1 kb Slc34a2, Elovl1 and Zdhhc3 promoter-luciferase constructs made in pGL3 reporter plasmids are depicted above the graphs. C/EBPα (green) and SREBP1c (red) represent consensus motifs on each mouse gene promoter. Transcription start sites are shown at +1 bp. The dose response effects of C/EBPα and SREBP1c expression after co-transfection with fixed amounts of the promoter-reporter constructs were assessed in MLE-15 cells, an immortalized mouse lung epithelial cell line, as measured by luciferase activity in 6-well plates. Values represent two independent experiments carried out in duplicate with means ± S.D. (n = 6).
