Figure 1. Differential effects of manipulating malonyl-coA levels in Nf2-null cells.

(A) Small molecules that increase malonyl-CoA levels by increasing its synthesis or by reducing its catabolism; (B) Effect of chemical inhibition of PDK on cerulenin toxicity. The PDK inhibitor sodium dichloroacetate (50 mM) was added together with the indicated concentrations of cerulenin, 4 hours after cell seeding, and cells were then incubated for 48 hours. Experiments were repeated 3 times. Mean values and 95% confidence intervals are shown. MEF Nf2−/− - Nf2-knockout murine embryonic fibroblasts, MEF Nf-2f/f – wild-type murine embryonic fibroblasts, KT21 – malignant NF2-deficient human meningioma cells, Aco7 – normal human arachnoid cells.
