1 Nicotine-mediated IkappaBalpha degradation and nuclear factor-kappa B (NF-kappaB) translocation dose-dependently. Nicotine nuclear factor kappa B subunit 1 Homo sapiens
2 Nicotine-mediated IkappaBalpha degradation and nuclear factor-kappa B (NF-kappaB) translocation dose-dependently. Nicotine nuclear factor kappa B subunit 1 Homo sapiens
3 Knockdown of NF-kappaB by short interfering RNA (siRNA) or specific inhibitor (Bay-11-7085) markedly suppressed nicotine-induced cell proliferation and upregulation of miR-16 and miR-21. Nicotine nuclear factor kappa B subunit 1 Homo sapiens
4 Interestingly, NF-kappaB-binding sites were located in both miR-16 and miR-21 gene transcriptional elements and we showed that nicotine enhanced the binding of NF-kappaB to the promoters of miR-16 and miR-21. Nicotine nuclear factor kappa B subunit 1 Homo sapiens
5 Interestingly, NF-kappaB-binding sites were located in both miR-16 and miR-21 gene transcriptional elements and we showed that nicotine enhanced the binding of NF-kappaB to the promoters of miR-16 and miR-21. Nicotine nuclear factor kappa B subunit 1 Homo sapiens
6 EP2 or EP4 siRNA or antagonists impaired the nicotine-mediated NF-kappaB activity, upregulation of miR-16 and miR-21 and cell proliferation. Nicotine nuclear factor kappa B subunit 1 Homo sapiens
7 Taken together, these results suggest that miR-16 and miR-21 are directly regulated by the transcription factor NF-kappaB and yet nicotine-promoted cell proliferation is mediated via EP2/4 receptors. Nicotine nuclear factor kappa B subunit 1 Homo sapiens
