Moreover, in some tumors, such as breast cancer, amplification of decoy receptor 3 is associated with inferior clinical outcomes [ 33].

However, in certain circumstances, RIP1 is deubiquitinated by the enzyme, cylindromatosis (CYLD), which leads to the dissociation of RIP1 and TRADD from complex I. Smac mimetic SM-164 potentiates APO2L/TRAIL- and doxorubicin-mediated anticancer activity in human hepatocellular carcinoma cells. In Vukovar, the wives and mothers of the dead resented the forensic team's mission to prove that their relatives had been mowed down by Serb fighters. A clear example is the polyubiquitination of the p10 subunit of caspase-8 mediated by CUL3 upon induction by TRAIL. The beauty and significance of Koff's work and of her drive to do it come through most powerfully when she is crouching over a mass grave, untangling limbs, scraping dirt from a corpse's clothes and finding, within what most of us would see as horror, something human that speaks.On the cell surface, cognate ligands from the TNF family CD95 (first apoptotic signal, Fas/Apo1) and TNF-related apoptosis-inducing ligand (TRAIL) engage with one of the major death receptors to attract the DD-containing molecules, FADD (Fas-associated death domain protein) and/or TNF receptor-associated death domain (TRADD). As a child, Koff buried dead birds in plastic bags in her yard so that she could dig them up later and examine their state of decay.

Since TRAIL has been shown to induce cell death in cancer cells compared to normal cells, TRAIL receptor and TRAIL ligands are attractive targets for anti-cancer therapy. ABT-199, a new Bcl-2–specific BH3 mimetic, has in vivo efficacy against aggressive Myc-driven mouse lymphomas without provoking thrombocytopenia. Several epidemiologic studies have investigated correlations between caspase gene polymorphisms and cancer risk, but how particular polymorphisms contribute to caspase function and expression has yet to be determined in many cases [ 33]. Such questions stalk Koff throughout The Bone Woman, a memoir of her work on mass graves for the International Criminal Tribunals for Rwanda and Yugoslavia.In contrast, positive regulators of caspase-8 mediate their effect by inducing posttranslational modifications, such as ubiquitination. cIAP1/2 contain a baculovirus IAP repeat (BIRD), a caspase-recruitment domain (CARD) and RING E3 ligases, which help to recruit TRAF1 and 2 and inhibit TNFα-apoptotic signaling.
