18485876 Wang L, Du F, Wang X: TNF-alpha induces two distinct caspase-8 activation pathways. Cell. 2008 May 16;133(4):693-703.

Cycloheximide promotes caspase-8 activation by eliminating endogenous caspase-8 inhibitor, c-FLIP, while Smac mimetic does so by triggering autodegradation of cIAP1 and cIAP2 (cIAP1/2), leading to the release of receptor interacting protein kinase (RIPK1) from the activated TNF receptor complex to form a caspase-8-activating complex consisting of RIPK1, FADD, and caspase-8.

18069034 Ying S, Christian JG, Paschen SA, Hacker G: Chlamydia trachomatis can protect host cells against apoptosis in the absence of cellular Inhibitor of Apoptosis Proteins and Mcl-1. Microbes Infect. 2008 Jan;10(1):97-101. Epub 2007 Oct 18.

Hypotheses have been proposed to explain this molecularly, including the up-regulation of host anti-apoptotic proteins such as cellular Inhibitor of Apoptosis Protein (IAP) 2 and the Bcl-2 protein Mcl-1.
Infection with Chlamydia trachomatis protected all cells equally well against apoptosis, which was induced either with tumour necrosis factor/cycloheximide (IAP-knock-out cells) or staurosporine (Mcl-1-knock-out).

Here, we report that the transcription of the inhibitor of apoptosis gene, cellular inhibitor of apoptosis protein 2, (c-IAP2), is significantly upregulated in HPV16 E6/E7-immortalized human oral keratinocytes (HOK16E6E7).
Overexpression of c-IAP2 in normal human oral keratinocyte conferred resistance to tumor necrosis factor-alpha (TNF-alpha)/cycloheximide (CHX)-induced apoptosis, suggesting the increased c-IAP2 expression in HOK16E6E7 may protect the cells from TNF-alpha-mediated cell death.

Cancer Res. 2006 Aug 15;66(16):8131-8.

These effects were nongenomic: they occurred rapidly and were not inhibited by cycloheximide or actinomycin D.
In addition, siRNA-Akt transfection followed by 1,25D3 treatment induced apoptosis much sooner than 1,25D3 alone. siRNA-Akt and 1,25D3 induced caspase-10 activation, suppressed the expression of c-IAP1 and XIAP, and promoted 1,25D3-induced caspase-3 activation.

Spontaneous neutrophil apoptosis and Mcl-1 degradation were prevented by cyclic AMP (cAMP) agonists (dibutyryl cAMP and prostaglandin E (1)), and the effects of cAMP agonists on neutrophils were highly resistant to cycloheximide, a protein synthesis inhibitor, although slight increase in Mcl-1 mRNA expression was induced by cAMP agonists.

The selected TRAIL-resistant cells were cross-resistant to TNF-alpha/cycloheximide but remained sensitive to DNA-damage drugs such as oxaliplatin and etoposide.
