p38 MAPK regulates FasL promoter activity. p38 (M) or pcDNA3 DO11.10 stable transfectants were transiently transfected with a FasL-511 luciferase construct, maintained in medium for 36 h at 37°C, and were then either left unstimulated or were stimulated with plate-bound anti-CD3 for 16 h. Luciferase activity in whole cell lysates was assayed and is shown as mean value ± SEM. Transfection efficiency was monitored by cotransfection of a pUC19 plasmid encoding β-galactosidase. Similar results were obtained in three independent and reproducible experiments.
