A decrease in ERK activation in SK-OV-3 cells was observed at a later time point, namely 6 h p.i. Infection with HAdV26 had no influence on p38 and JNK activation in A549 cells, but increased p38 activation at 1 h p.i. and decreased JNK activation 6 h p.i. in SK-OV-3 cells. This evidence concerns the gene MAPK8 and infection.
