Figure 3From: Levels of pro-apoptotic regulator Bad and anti-apoptotic regulator Bcl-xL determine the type of the apoptotic logic gateBifurcation diagram for Casp vs. Bax . Saddle-node bifurcation point is (B a xbif, C a s pbif) ≃ (5000, 1000). The unstable steady state is marked by dashed line. Solid lines show high and low stable steady states corresponding to apoptosis and survival, respectively. (Note the logarithmic scale on the vertical axis).Back to article page
