Clin Exp Immunol. 2005 Dec;142(3):490-7.

Periodontitis, a chronic inflammatory disease, is characterized by increased expression of interleukin (IL)-1 and other inflammatory mediators resulting in extensive osteoclast formation and bone loss.
Human gingival fibroblasts (HGF) and periodontal ligament fibroblasts (PDL) were stimulated with IL-1alpha with or without protein synthesis inhibitor cycloheximide (CHX), protein kinase A (PKA) inhibitors, protein kinase C (PKC) inhibitors and prostaglandin E (2) (PGE (2)) inhibitor.

Am J Physiol Endocrinol Metab. 2008 Dec;295(6):E1390-400. Epub 2008 Oct 14.

Actinomycin D almost completely abolished the LPS effect, whereas cycloheximide decreased the expression at 12 h, indicating that the LPS-induced ADRP expression was stimulated at the transcriptional level and was also mediated by new protein synthesis.
In addition, preceding the increase of the ADRP mRNA, LPS induced the expression of interleukin (IL)-6, IL-1alpha, and interferon-beta mRNAs, all of which stimulated the ADRP expression.

Cycloheximide experiments showed that the decreased promoter activity is independent of de novo protein synthesis and therefore most likely due to posttranslational modifications such as phosphorylation or subcellular relocalization.
The proinflammatory cytokine interleukin (IL)-1beta decreases thyroid hormone receptor (TR) beta1 mRNA in an NFkappaB-dependent way.

In the culture of macrophages (Raw264.7), HGF enhanced the LPS-mediated HO-1 induction, and this effect was abolished by cycloheximide, but not by actinomycin-D, thus suggesting that a post-transcriptional pathway is involved in HGF-mediated up-regulation of HO-1.
In this process, interleukin (IL)-6 and IL-10 are key contributors for eliciting pro- and anti-inflammatory responses, respectively.

The T helper type 1 cytokine interleukin (IL)-18 has been shown to induce the maturation of these cells towards a dendritic phenotype and, moreover, is able to mediate IFNgamma production in this model.
Blockage of translation by cycloheximide, usage of neutralizing antibodies, and the inability of IFNgamma to mediate significant p38 mitogen-activated protein kinase activation in KG-1 cells clearly revealed that activation of T-bet was not via autocrine IFNgamma.

J Infect Dis. 2006 Feb 15;193(4):505-14. Epub 2006 Jan 17.

BACKGROUND: Interleukin (IL)-7 levels are increased in patients with human immunodeficiency virus type 1 (HIV-1)-associated lymphopenia; however, the effects of this on IL-7 receptor (IL-7R) expression, disease progression, and immune reconstitution remain unclear.
The effects of IL-7 and cycloheximide on IL-7R expression by peripheral blood mononuclear cells were examined in vitro.

J Interferon Cytokine Res. 2008 Aug;28(8):509-21.

When human fibroblast-like synoviocytes line MH7A was treated with cigarette smoke condensate (CSC), either mainstream or sidestream, expression levels of interleukin (IL)-1alpha, IL-1beta, IL-6, IL-8, and CYP1A1 mRNA were upregulated in both time- and dose-dependent manners.
Cycloheximide treatment indicated that the augmenting effect of CSC on IL-1alpha, IL-1beta and IL-8, but not IL-6 and CYP1A1, mRNA expression requires de novo protein synthesis.

BACKGROUND: Interleukin (IL)-8 and transforming growth factor (TGF)-beta1 are overexpressed in advanced prostate cancer.
TGF-beta1 stimulated IL-8 expression in dose- and time-dependent manners, which was blocked by cycloheximide (CHX) and actinomycin D (ActD).

UVB exposure significantly increased the release of interleukin (IL)-8 and modestly increased IL-1alpha production, but cytokines such as IL-2, IL-4, IL-6, IL-10, IL-12, IL-13, tumour necrosis factor (TNF)-alpha and interferon (IFN)-gamma were unaffected.
Cycloheximide reduced the UVB-mediated induction of IL-8 by 30-40%, suggesting that new protein synthesis contributed to IL-8 production.

15722640 Park CS, Choi EN, Kim JS, Choi YS, Rhim TY, Chang HS, Chung IY: Interferon-gamma inhibits in vitro mobilization of eosinophils by interleukin-5. Int Arch Allergy Immunol. 2005 Mar;136(3):295-302. Epub 2005 Feb 16.

RESULTS: Interleukin (IL)-5, IL-6, and tumor necrosis factor (TNF) induced an eosinophil shape change, whereas interferon (IFN)-gamma significantly inhibited the shape change.
We further analyzed the IFN-gamma effect, showing that pretreatment with IFN-gamma strongly suppressed IL-5-induced eosinophil shape change, and cycloheximide (CHX) abrogated the suppression by IFN-gamma, suggesting that new protein synthesis is required for the inhibitory effect by this cytokine.

Interleukin (IL)-1beta is known to play a role in the formation of brain edema after various types of injury.
It appeared that IL-1beta increased the level of AQP4 mRNA without involvement of de novo protein synthesis because cycloheximide, a protein synthesis inhibitor, did not inhibit the effects of IL-1beta.

17304101 Pearl-Yafe M, Fabian I, Halperin D, Flatau E, Werber S, Shalit I: Interferon-gamma and bacterial lipopolysaccharide act synergistically on human neutrophils enhancing interleukin-8, interleukin-1beta, tumor necrosis factor-alpha, and interleukin-12 p70 secretion and phagocytosis via upregulation of toll-like receptor 4. Shock. 2007 Mar;27(3):226-31.

Using the protein synthesis inhibitor cycloheximide and measuring the expression of CD35 in neutrophils stimulated with IFN-gamma and LPS alone or in combination, we could demonstrate that IFN-gamma enhances TLR4 by de novo protein synthesis, whereas the addition of LPS acts synergistically by enhancing vesicular mobilization to the cell surface.
Costimulation with IFN-gamma and LPS induced neutrophil activation and enhanced secretion of the cytokines, interleukin (IL)-8, IL-1beta, tumor necrosis factor-alpha, and IL-12 p70, and phagocytosis of latex beads, processes that were blocked by a monoclonal antibody specific for TLR4.

In this report, we studied the effect of MV infection on the production of interleukin (IL)-8 by the pulmonary epithelial cells.
The IL-8 production was little affected by UV-inactivation of MV and scarcely suppressed by cycloheximide treatment.

To further characterise the HIC functional relationship with the immune system, we sought to analyse the HIC gene expression profile in immune cells and to determine if immunomodulatory cytokines, such as interleukin (IL)-2, could regulate the expression of HIC mRNA.
Addition of cycloheximide indicated that the IL-2 effects were independent of de novo protein synthesis and that the HIC gene is a direct target of IL-2.

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.
Treatment with RCE (10approximately50 microg/ml) decreased the 0.2 mM H (2) O (2)-induced apoptosis and production of tumor necrosis factor (TNF)-alpha, interleukin (IL)-6 and nitric oxide (NO) in osteoblasts.

17635918 Jang BC, Sung SH, Park JG, Park JW, Bae JH, Shin DH, Park GY, Han SB, Suh SI: Glucosamine hydrochloride specifically inhibits COX-2 by preventing COX-2 N-glycosylation and by increasing COX-2 protein turnover in a proteasome-dependent manner. J Biol Chem. 2007 Sep 21;282(38):27622-32. Epub 2007 Jul 16.


Remarkably, GS-HCl-mediated decrease in COX-2 molecular mass was associated with inhibition of COX-2 N-glycosylation during translation, as assessed by the effect of tunicamycin, the protein N-glycosylation inhibitor, or of cycloheximide, the translation inhibitor, on COX-2 modification.
