The NFκB inhibitory peptide, IκBα, prevents human vascular smooth muscle proliferation Craig H Selzman, MD, Brian D Shames, MD, Robert C McIntyre, MD, Anirban Banerjee, PhD, Alden H Harken, MD The Annals of Thoracic Surgery Volume 67, Issue 5, Pages 1227-1231 (May 1999) DOI: 10.1016/S0003-4975(99)00252-0
Fig 1 Growth factor and cytokine-induced vascular smooth muscle proliferation. VSMCs were incubated in control media (Cont) or increasing concentrations of FGF (A) or TNF (B) for 24 h. Both FGF and TNF induced concentration-dependent VSMC (∗p < 0.002 versus control). The Annals of Thoracic Surgery 1999 67, 1227-1231DOI: (10.1016/S0003-4975(99)00252-0)
Fig 2 Influence of nonspecific and specific NFκB blockade on unstimulated VSMC growth. Dexamethasone (Dex), calpain inhibitor-1 (CI-1), liposomes containing the GST moiety alone (Lipo), and liposomal IκBα (IκBα) had no effect on unstimulated VSMC proliferation.

Fig 3 Influence of nonspecific NFκB inhibition on mitogen-stimulated VSMC. FGF (10 ng/mL) and TNF (10 ng/mL) induced VSMC proliferation compared with control (†p < 0.001). Both dexamethasone (Dex) and calpain inhibitor-1 (CI-1) inhibit FGF- and TNF-induced VSMC proliferation (∗p < 0.001, versus [A] FGF and [B] TNF).

Fig 4 Influence of specific NFκB blockade with liposomal delivery of IκBα on mitogen-stimulated VSMC. Both FGF (10 ng/mL) and TNF (10 ng/mL) induced VSMC proliferation compared with control (†p < 0.001). Simultaneous incubation with liposome containing the GST moiety alone (Lipo) had no effect on FGF- or TNF-induced proliferation. Liposomal delivery of IκBα (IκBα) inhibited both FGF- and TNF-stimulated VSMC proliferation (∗p < 0.001, versus [A] FGF and [B] TNF).
