Nuclear run-on assays demonstrate that : ( 1 ) induction of c-jun and c-fos expression by TPA is regulated by transcriptional mechanisms , ( 2 ) TPA -induced expression of c-jun and c-fos does not require protein synthesis , and ( 3 ) TPA -induced expression of both genes is inhibited at the transcriptional level by dexamethasone .
