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.

Cycloheximide did not antagonize the inhibitory effects of TNF on GH-inducible IGF-I expression.
The current study describes construction of a GH-inducible IGF-I promoter construct and investigates mechanisms by which TNF and nuclear factor-kappaB (NFkappaB) inhibit GH-inducible gene expression.

Five out of the six transcripts were indeed induced by PACAP alone soon (between 30 min and 3 h) after cell treatment. beta-Cell translocation gene 2, antiproliferative (Btg2), serum/glucocorticoid-regulated kinase (Sgk), nuclear factor for the kappa chain of B-cells (NFkappaB), seven in absentia homologue 2 (Siah2) and FBJ osteosarcoma related oncogene (Fos) showed a 2.5-200-fold induction by PACAP between 15 min and 3 h, and mRNA levels returned either to baseline or near baseline after 6 h.

The underlying pathway includes activation of JAK2, STAT3, p38 and NFkappaB.
For the pathway determination following inhibitors were used: piceatannol (signal transducer and activation of transcription (STAT) 3 phosphorylation), wortmannin (phosphatiylinositol 3-kinase (PI3K)), SB203580 (p38 mitogen-activated protein kinase (MAPK)), AG490 (Janus kinase (JAK) 2), PD98059 (mitogen-activated protein kinase kinase (MEK) 1/2), parthenolide (nuclear factor kappaB) and cycloheximide (protein biosynthesis).

In the presence of cycloheximide, the selected SCCHN sublines become susceptible to CH-11 Ab, and showed cleavage of caspase-8, suggesting that apoptosis resistance was mediated by an inhibitory protein (s) acting upstream of caspase-8.
A high phosphorylation level of IkappaB kappa, NFkappaB activation and upregulation of Bcl-2 expression were observed in the FAP-1+ sublines.

17523868 Morton ER, Blaho JA: Herpes simplex virus blocks Fas-mediated apoptosis independent of viral activation of NF-kappaB in human epithelial HEp-2 cells. J Interferon Cytokine Res. 2007 May;27(5):365-76.

We found the following: (1) Treatment of HEp-2 cells with anti-Fas antibody or Fas ligand (FasL) alone did not induce apoptosis. (2) In addition, these inducers did not activate NF-kappaB in these cells. (3) The addition of cycloheximide (CHX) during these treatments caused a dramatic increase in programmed cell death. (4) HEp-2 cells infected with HSV for 6 h prior to anti-Fas plus CHX treatment were nonapoptotic, and (5) these cells possessed nuclear NFkappaB. (6) HSV blocked anti-Fas or FasL plus CHX-induced apoptosis in HEp-2 cells that stably expressed a dominant-negative form of IkappaBalpha.
These results indicate that HSV infection can block the process of Fas-mediated apoptosis through a mechanism that is independent of viral activation of NFkappaB.

Since infection during inhibition of protein expression by cycloheximide or inactivation of viral gene expression by UV treatment did not trigger IRF3 activation or ISG expression by RhCMV, we conclude that RhCMV virions contain a novel inhibitor of IFN-independent viral induction of ISG expression by IRF3.

We checked the stress-inducible transcription factor, nuclear factor kappa B (NF-kappaB), which was persistently activated by cycloheximide but not by other agents after 24 hours indicating no role of NFkappaB in the RNase L-induction.
