Disulfiram was also able to induce accumulation of p27 (Kip1) and to prolong the half-life of c-Myc, both targets for proteasome-dependent degradation.

METHODOLOGY/PRINCIPAL FINDINGS: Here, we chose four structurally different chemical inhibitors of translation elongation: homoharringtonine, bruceantin, didemnin B and cycloheximide, and tested their ability to alter the chemoresistance of Emu-myc lymphomas harbouring lesions in Pten, Tsc2, Bcl-2, or eIF4E.
We attribute this effect to a reduction in levels of pro-oncogenic or pro-survival proteins having short half-lives, like Mcl-1, cyclin D1 or c-Myc.

Here, we investigated whether induction of c-Myc by OA or protein synthesis inhibitor cycloheximide contributed to HBC growth inhibition and the mechanisms involved.

Cancer Chemother Pharmacol. 2005 Jul;56(1):22-8. Epub 2005 Mar 25.

Moreover, cotreatment of protein synthesis inhibitor cycloheximide (CHX) resulted in the induction of hTERT transcription by FR901228.
We further examined the effect of FR901228 on c-myc protein, which is one of the main hTERT transcription activators.

However, the presence of the protein synthesis inhibitor cycloheximide could reverse the repression of Myc, indicating the indirect repression of human NDRG1 by Myc.
The data revealed that both N-Myc and c-Myc can repress human NDRG1 at the transcriptional level.

Consistent with the results of these transient transfection assays, we were unable to demonstrate the expected beta-catenin dependent, TCF/Lef mediated inhibition of cyclin D1 and c-myc gene transcription in breast cells overexpressing DKK-1.

Proc Natl Acad Sci U S A. 2008 Jul 1;105(26):8866-71. Epub 2008 Jun 25.


We also show that there is a miR-34 target site within the 3' UTR of c-myc mRNA and that promoter dependency is also true for this endogenous 3' UTR.
