A. Cells were pretreated with either vehicle or 40uM CHX 1h before vehicle, 10μM LCL521, or in combination with 10 μM LCL521 for 1, 8 and 24h. ACDase protein expression (α-and P-ACDase) was then visualized by western blot as described; actin was utilized to monitor protein loading and transfer. B. Matched SL-profile, which are presented as means ± st dev. of triplicates, * p value <0.005; ** p value <0.05 (vs Control).
