The aldosterone-induced osteopontin mRNA expression was completely blocked by a transcription inhibitor, actinomycin D, and a protein synthesis inhibitor, cycloheximide.

The protein synthesis inhibitor cycloheximide (CH) was used in this model to test if new protein synthesis was necessary for its cardioprotective effects.

The protective effect of OPN was also blocked by the protein synthesis inhibitor cycloheximide, suggesting that the neuroprotective effect of OPN required new protein synthesis.

To clarify the effects of glucocorticoids (GCs) on osteoblast and adipocyte differentiation, we investigated the effects of dexamethasone (Dex), a GC analogue on transcription factors for osteoblasts (Runx2, Dlx5 and Osterix) and adipocytes (C/EBPs such as C/EBPalpha, C/EBPbeta and C/EBPdelta, and PPARgamma2), late osteoblastic markers, bone sialoprotein (BSP) and osteocalcin (OC), and adipocyte differentiation-dependent protein, aP2 in a clonal mesenchymal progenitor cell line, ROB-C26 (C26).
Cycloheximide pretreatment indicated that Dex signaling immediately increases expressions of the C/EBPs and Dlx5, while expressions of the rest of the genes require de novo protein synthesis.
