The effect of genistein (10 (-5) M) plus zinc (10 (-4) M) in enhancing the expression of alpha1 (I) collagen, alkaline phosphatase, or osteocalcin mRNAs in osteoblastic cells was completely prevented with a culture of cycloheximide (10 (-7) M), an inhibitor of protein synthesis, or 5,6-dichloro-1-beta-D-ribofuranosylbenimidazole (DRB) (10 (-6) M), an inhibitor of transcriptional activity.

By means of alkaline phosphatase (ALP) activity, osteocalcin, and type I collagen enzyme-linked immunosorbent assay (ELISA), we have shown that myricetin exhibits a significant induction of differentiation in MG-63 and hFOB human osteoblasts.

17368935 Choi EM: Modulatory effects of luteolin on osteoblastic function and inflammatory mediators in osteoblastic MC3T3-E1 cells. Cell Biol Int. 2007 Sep;31(9):870-7. Epub 2007 Feb 11.

Luteolin (1microM) caused a significant elevation of collagen content, alkaline phosphatase (ALP) activity, and osteocalcin secretion in the cells (P <0.05).
The effect of luteolin in increasing collagen content and ALP activity was completely prevented by the presence of 10 (-6) M cycloheximide and 10 (-6) M tamoxifen, suggesting that luteolin's effect results from a newly synthesized protein component and might be partly involved in estrogen action.

The addition of protein synthesis inhibitor, cycloheximide (CHX), partially inhibits the induction of type X collagen and MMP-13 mRNA by RA.
However, RA downregulates ALPase, bone gla protein (BGP) mRNAs and mineralization.

Biochanin A (1-50 microM) caused a significant elevation of cell growth, alkaline phosphatase (ALP) activity, collagen content, and osteocalcin secretion in osteoblastic MC3T3-E1 cells (p <0.05).
The effect of biochanin A (10 microM) in increasing ALP activity and collagen content was completely prevented by the presence of 10 (-6) M cycloheximide and 10 (-6) M tamoxifen, suggesting that biochanin A's effect results from a newly synthesized protein component and might be partly involved in estrogen action.

The effect of zinc sulfate on the mRNA expressions in Runx2, osteocalcin, alpha1 (I) collagen, insulin-like growth factor-I (IGF-I), transforming growth factor-beta1 (TGF-beta1), osteoprotegerin (OPG), regucalcin, zinc transporter 1 (ZIP1), or glyceroaldehyde-3-phosphate dehydrogenase (G3PDH) in osteoblastic MC3T3-E1 cells in vitro was investigated.
The stimulatory effects of zinc sulfate on Runx2, OPG, or regucalcin mRNAs were significantly prevented in the presence of cycloheximide (10 (-7) M), an inhibitor of protein synthesis, or 5,6-dichloro-1-beta-D-ribofuranosyl-benzimidazole (10 (-6) M), an inhibitor of transcription activity.

Glabridin (1-10microM) significantly increased the growth of MC3T3-E1 cells and caused a significant elevation of alkaline phosphatase (ALP) activity, collagen content and osteocalcin secretion in the cells (P <0.05).
The effect of glabridin (10microM) in increasing ALP activity and collagen content was completely prevented by the presence of 10 (-6) M cycloheximide and 10 (-6) M tamoxifen, suggesting that glabridin's effect results from a newly synthesized protein component and might be partly involved in estrogen action.

RCE (10approximately50 microg/ml) caused a significant elevation in cell viability, alkaline phosphatase (ALP) activity, collagen content, and osteocalcin secretion in the cells.
The effect of RCE (50 microg/ml) in increasing cell viability, ALP activity, and collagen content was prevented by the presence of 10 (-6) M cycloheximide and 10 (-6) M tamoxifen, suggesting that RCE's effect results from a newly synthesized protein component and might be partly involved in estrogen action.

Mol Cell Biochem. 2008 Jan;307(1-2):209-19. Epub 2007 Sep 25.


Such an effect was not seen in the presence of cycloheximide (10 (-7) M), an inhibitor of protein synthesis, or 5,6-dichloro-1-beta-D: -ribofuranosyl-benzimidazole (DRB; 10 (-6) M), an inhibitor of transcriptional activity.

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.
