In contrast, such activation was either very weak or nil when cells were treated by IFN-beta or tumor necrosis factor-alpha TNF-alpha , despite the fact they both efficiently induce de novo synthesis of the short-lived IRF-1 in L cells. In fact, efficient activation of the IRF-E apparently requires an event in addition to de novo IRF-1 induction, which can be elicited by NDV even in the presence of protein synthesis inhibitor, cycloheximide. Hence our results suggest the importance of IRF-1 synthesis and post-translational modification event s , possibly phosphorylation for the efficient activation of IRF-Es, which are otherwise under negative regulation by IRF National Center for Biotechnology Information , U.
