CYP24A1 mRNA induction in RPTCs was also inhibited by the protein synthesis inhibitor cycloheximide.

The effect of paricalcitol on suppressing PAI-1 in SMC was blocked by cycloheximide, suggesting that protein synthesis was involved.
As a comparison, SMC expressed VDR and paricalcitol induced CYP24A1 mRNA in SMC (> 150-fold at 10 nM) dose-dependently.

The effect of paricalcitol on THBS1 in SMC was blocked by cycloheximide, while its effect on TM and CYP24A1 was not affected, suggesting that the regulation of THBS1 by VDR may be mediated through intermediate factors, but that TM is likely a direct target of VDR.
