Activation of Cell Surface Bound 20S Proteasome Inhibits Vascular Cell Growth and Arteriogenesis

Figure 3

(a) CTA 157-2 specifically activates 20S proteasome and (b) control IgM antibody is without effect. (c) Proteasome inhibitor lactacystin reduces proteasome activity as expected. (d) Activation of the proteasome is purified membrane preparations with CTA 157-2 treatment.
