The HeLa cervical cancer cells expressing a dominant negative mutant (DN) of a cytosolic 2-cysPrx manifested remarkable increase in intracellular reactive oxygen species level, which was counteracted by catalase administration, and apoptotic cell death induced by combined treatment of TNF-alpha and cycloheximide compared to the control (CT) cells.
The apoptosis enhanced by DN expression was shown to be dependent on a typical FADD/caspase pathway.

In the presence of the protein synthesis inhibitor cycloheximide, LPS primarily induces caspase-dependent apoptotic cell death of HUVECs, which is blocked by siRNA-mediated knockdown of myeloid differentiation factor 88 adaptor protein but not of Toll-like receptor-associated interferon-inducing factor.
However, based on the use of proteinase inhibitors, cell death changes from being principally caspase-dependent to being principally cathepsin B (Cat B)-dependent.

We demonstrate that global induction of apoptosis in primary bovine lens epithelial (LEC) or fibroblastic mouse NIH-3T3 cells by staurosporine, puromycin, cycloheximide, or etoposide is accompanied by a decrease in coupling by gap junctions.
Cell coupling as tested by neurobiotin spreading was maintained when the LEC or NIH-3T3 cells were pre-incubated with the pan-caspase inhibitor zVAD or the caspase-3 inhibiting tetrapeptide DEVD.

Interestingly, the activation of caspase-3 and -8 and DNA fragmentation were significantly prevented in the presence of cycloheximide, suggesting that Compound K-induced apoptosis is dependent on de novo protein synthesis.
In addition, compound-K induced a series of intracellular events associated with both the mitochondrial- and death receptor-dependent apoptotic pathways, namely, (1) the activation of caspases-3, -8, and -9; (2) the loss of mitochondrial membrane potential; (3) the release of cytochrome c and Smac/DIABLO to the cytosol; (4) the translocation of Bid and Bax to mitochondria; and (5) the downregulations of Bcl-2 and Bcl-xL.

The mechanism by which NF-kappaB was protecting SMC against collagen fragment-induced apoptosis was a transcriptional activation of several endogenous caspase inhibitors of the inhibitor of apoptosis protein (IAP) family as: (1) the expression of xIAP, c-IAP2, and survivin was potently induced by collagen fragments; (2) IAP expression was abrogated by superrepressor IkappaBalpha; and (3) knockdown of each of the 3 IAPs by small interfering RNA (siRNA) resulted in enhanced apoptosis after collagen fragment treatment.

Syncytia and HA formation were blocked by cycloheximide and ribavirin but not actinomycin D, suggesting that expression of CSV genes were required for both phenomena.

In contrast with direct apoptotic stimuli, such as the anti-cancer drug etoposide, leading to caspase-dependent degradation of S1 and S5a, the effect of IEX-1 is independent of proteolytic cleavage of these proteins.
Furthermore, the decreasing effect of IEX-1 on S5a and S1 expression is still seen in the presence of cycloheximide, but not in the presence of actinomycin D, and quantitative real-time PCR revealed lower mRNA levels of S5a and S1 in IEX-1-overexpressing cells, suggesting an interference of IEX-1 with the gene transcription of S5a and S1.

The rainbow trout macrophage cell line RTS11 was found to be considerably more sensitive than rainbow trout fibroblast (RTG-2) and Chinook salmon epithelial (CHSE-214) cell lines to killing by macromolecular synthesis inhibitors, actinomycin D (AMD) and cycloheximide (CHX), a synthetic double stranded RNA (dsRNA), polyinosinic:polycytidylic acid (poly IC), and combinations of poly IC with AMD or CHX.
By contrast, z-VAD-fmk almost completely abrogated killing by co-treatments of poly IC and low concentrations of AMD or CHX, suggesting caspase dependence.

INTRODUCTION: Caspase-3 is one of the executioner caspases activated as a result of apoptosis.
We compared the ability of two novel radiolabeled isatins, [18F] WC-IV-3 and [11C] WC-98, to detect caspase-3 activation in a rat model of cycloheximide-induced liver injury.

15647476 Verma P, Chierzi S, Codd AM, Campbell DS, Meyer RL, Holt CE, Fawcett JW: Axonal protein synthesis and degradation are necessary for efficient growth cone regeneration. J Neurosci. 2005 Jan 12;25(2):331-42.

Collectively, these findings suggest that local protein synthesis and degradation, controlled by various TOR-, p38 MAPK-, and caspase-dependent pathways, underlie growth cone initiation after axotomy.
Application of protein synthesis inhibitors (cycloheximide and anisomycin) to cut axons, including axons whose cell bodies were removed, or proteasome inhibitors (lactacystin and N-acetyl-Nor-Leu-Leu-Al) all result in a reduction in the proportion of transected axons able to reform growth cones.

15541727 McNeish IA, Lopes R, Bell SJ, McKay TR, Fernandez M, Lockley M, Wheatley SP, Lemoine NR: Survivin interacts with Smac/DIABLO in ovarian carcinoma cells but is redundant in Smac-mediated apoptosis. Exp Cell Res. 2005 Jan 1;302(1):69-82.

We sought to stimulate the mitochondrial pathway of apoptosis by constructing a recombinant adenovirus encoding mature, processed Smac/DIABLO (Ad CMV tSmac), the second mitochondrial activator of caspases.
This down-regulation does not result from transcriptional changes, as determined by quantitative real-time PCR, but cycloheximide treatment indicates that survivin half-life is reduced from 6 to 2 h, which is secondary to ubiquitination and proteasomal degradation.
