The protein synthesis inhibitor cycloheximide significantly inhibited metal-mediated induction of Nqo1 and Gst ya mRNAs, which coincided with a decrease in the nuclear factor erythroid 2-related factor 2 (Nrf2) protein expression, implying the requirement of Nrf2 protein synthesis for the induction of these genes.

The induction of heme oxygenase-1 in renal adenocarcinoma cells was blocked by actinomycin D and cycloheximide and was abolished by the phosphatidylinositol 3-kinase inhibitor, LY294002, but not by the inactive analog LY303511.
The transcription factor NF-E2-related factor-2 was found to translocate to the nucleus following insulin treatment in a phosphatidylinositol 3-kinase-dependent manner.

Sulforaphane is known to be an indirect antioxidant that acts by inducing NF-E2-related factor 2 (Nrf2)-dependent phase II enzymes.
Actinomycin D (an RNA synthesis inhibitor) and cycloheximide (a protein synthesis inhibitor) inhibited sulforaphane-responsive HO-1 mRNA expression, indicating that sulforaphane is a requirement for transcription and de novo protein synthesis.

Carcinogenesis. 2008 Mar;29(3):594-9. Epub 2007 Oct 4.

The induction of NF-E2-related factor-2 (Nrf2)-mediated detoxifying/antioxidant enzymes is recognized as an effective strategy for cancer chemoprevention.
Using chemical inhibitors of protein synthesis (cycloheximide) and 26S proteosomal degradation (MG-132), we observed that the induction of Nrf2 protein by 3MP-ITC appeared to be post-translationally regulated. 3MP-ITC activated ERK1/2 and JNK1/2 and the activation of antioxidant response element (ARE) by 3MP-ITC was significantly attenuated by chemical inhibition of PKC and PI3K signaling pathways in HepG2C8 cells.

Free Radic Biol Med. 2007 Jan 15;42(2):260-9. Epub 2006 Oct 20.

Nrf2 was rapidly degraded in cells treated with cycloheximide under static conditions, but shear stress decreased the rate of Nrf2 degradation.

We also found that PD98059, a MEK (MAPK/ERK kinase) inhibitor, attenuated the eupatilin-induced HO-1 expression and nuclear translocation of transcription factor Nrf2 (nuclear factor erythroid 2-related factor 2).
Pretreatment of ISMC with cycloheximide, an inhibitor of protein synthesis, attenuated the cytoprotective effect of eupatilin, suggesting that eupatilin induces proteins that are responsible for the cytoprotection.

J Biol Chem. 2005 Jul 8;280(27):25571-9. Epub 2005 May 3.

FGF-1 induced the expression of HO-1 in cultured rat spinal cord astrocytes, which was dependent on FGF receptor activation and prevented by cycloheximide.

19897490 Kaspar JW, Jaiswal AK: Antioxidant-induced phosphorylation of tyrosine 486 leads to rapid nuclear export of Bach1 that allows Nrf2 to bind to the antioxidant response element and activate defensive gene expression. J Biol Chem. 2010 Jan 1;285(1):153-62. Epub 2009 Nov 6.

Bach1 levels inside the nucleus returned to normal at 4 h after antioxidant treatment in the absence but not in the presence of protein synthesis inhibitor cycloheximide.
Antioxidants cause stabilization and nuclear translocation of NF-E2-related factor 2 (Nrf2), where it binds to the antioxidant response element (ARE) and induces up-regulation of defensive genes that protect cells against oxidative and electrophilic stress.

Nf-E2 related factor-2 (Nrf2) is a basic leucine zipper transcription factor that binds and activates the antioxidant response element (ARE) in the promoters of many antioxidant and detoxification genes.
Although inhibiting protein synthesis with cycloheximide prevented H (2) O (2) from elevating Nrf2 protein level, RNA synthesis inhibition with actinomycin D failed to do so.
