Here, we have examined the effect of nonclassical, i.e., nonligand binding, AhR activation by omeprazole upon human insulin-like growth factor binding protein (hIGFBP)-1, a secreted phosphoprotein involved in regulation of insulin-like growth factor-I/II bioavailability and mitogenic activity.
Cotreatment with cycloheximide further suggests a direct transcriptional role for hAhR at the hIGFBP-1 promoter.

Biol Reprod. 2005 May;72(5):1177-86. Epub 2005 Jan 12.


A combination of recombinant human (rh) insulin-like growth factor-I (IGF-I) (25 nM) and the maturation-inducing hormone (MIH), 17,20beta,21-trihydroxy-4-pregnen-3-one (20beta-S; 72.5 nM), induced germinal vesicle breakdown (GVBD) in ovarian follicles of white bass incubated in vitro, whereas a four times greater concentration of each hormone was ineffective alone.

Comp Biochem Physiol A Mol Integr Physiol. 2006 May;144(1):63-77. Epub 2006 Mar 10.

Cycloheximide was shown to inhibit the induction of GVBD and DHP production by IGF-I, b-insulin and HCG.
In vitro germinal vesicle breakdown (GVBD) in Cyprinus carpio oocytes was induced by recombinant human insulin-like growth factor-I and -II (IGF-I and IGF-II) and bovine insulin (b-insulin).

We found that insulin-like growth factor-I (IGF-I) was significantly more effective at preventing TNF-alpha-induced apoptosis when cells were first subjected to mechanical loading by exposure to either unidirectional or oscillatory fluid flow compared to cells that were maintained in static culture.

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.

Also, the stimulating effect of albumin on cell proliferation was completely prevented in the presence of cycloheximide (10 (-7) M), an inhibitor of protein synthesis, or 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB), an inhibitor of transcriptional activity.

Incubation of ovarian tissue with GH in the presence of actinomycin D: or cycloheximide or barramundi IGF-I antiserum was also made separately.

J Neurochem. 2006 Feb;96(3):777-89. Epub 2006 Jan 9.


Therefore, NEP may play an important role during muscle cell differentiation, possibly through the regulation, either directly or indirectly, of the insulin-like growth factor I-driven myogenic programme.

The stimulatory effect of beta-cryptoxanthin (10 (-6) M) on cellular biochemical components was completely prevented in the presence of cycloheximide (10 (-6) M), an inhibitor of protein synthesis, or 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB; 10 (-9) M), an inhibitor of transcriptional activity.
The expressions of insulin-like growth factor (IGF)-I and transforming growth factor (TGF)-beta1 mRNAs were demonstrated by reverse transcription-polymerase chain reaction (RT-PCR) analysis in osteoblastic cells using mouse IGF-I or TGF-beta1-specific primers.

The effect of regucalcin in decreasing cellular protein content was seen in the presence of insulin-like growth factor-I (IGF-I; 10 (-9) or 10 (-8) M).
The presence of regucalcin did not have a significant effect on protein and DNA contents in the cells cultured with cycloheximide (10 (-7) M), an inhibitor of protein synthesis, or 5,6-dichloro -1-beta-D-ribofuranosylbenzimidazole (10 (-6) M), an inhibitor of transcription activity; which each inhibitor caused a significant decrease in those contents.
