- _4 value "Pharmacological inhibition of NF-kappaB blocked LPS-induced Cebpd transcription (Fig. 1d), and LPS-induced Cebpd mRNA (Fig. 1d) and protein (Fig. 1e) quantities were substantially increased in Atf3-null macrophages. Taken together, these data demonstrate that LPS-induced transcription of Cebpd is absolutely dependent on NFkappaB, and that NFkappaB-dependent Cebpd mRNA production is attenuated by ATF3. ChIP analysis demonstrated rapid and transient recruitment of Rel to the promoter of the Cebpd gene; maximal binding was seen 1 hr after stimulation with LPS (Fig. 1f). By contrast, LPS-stimulated ATF3 binding to the promoter of the Cebpd gene (over basal amounts) occurred after 3 h and was sustained (Fig. 1f). " provenance.
