- Genotoxic agents are widely used anti-cancer therapies because of their ability to interfere with highly proliferative cells. An important outcome of these interventions is the induction of a state of permanent arrest also known as cellular senescence. However, senescent cancer cells are characterized by genomic instability and are at risk of escaping the growth arrest to eventually facilitate cancer relapse. The tumor necrosis factor related apoptosis inducing ligand (TRAIL) signals extrinsic apoptosis via Death Receptors (DR) 4 and 5, while Decoy Receptors (DcR) 1 and 2, and Osteoprotegerin (OPG) are homologous to death receptors but incapable of transducing an apoptotic signal. The use of recombinant TRAIL as an anti-cancer strategy in combination with chemotherapy is currently in development, and a major question remains whether senescent cancer cells respond to TRAIL. Here, we show variable sensitivity of cancer cells to TRAIL after senescence induction, and upregulation of both pro-apoptotic and anti-apoptotic receptors in therapy-induced senescent cancer cells. A DR5-selective TRAIL variant (DHER), unable to bind to DcR1 or OPG, was more effective in inducing apoptosis of senescent cancer cells compared to wild-type TRAIL. Importantly, no apoptosis induction was observed in non-cancerous cells, even at the highest concentrations tested. Our results suggest that targeting DR5 can serve as a novel therapeutic strategy for the elimination of therapy-induced senescent cancer cells. - Source: PubMed

Soto-Gamez AbelWang YizhouZhou XinyuSeras LorinaQuax WimDemaria Marco - Tumour necrosis factor-alpha-related apoptosis-inducing ligand (TRAIL) is a member of the tumour necrosis factor-alpha (TNF-alpha) family of cytokines which is known to induce apoptosis upon binding to its death domain-containing receptors, DR4/TRAIL-R1 and DR5/TRAIL-R2. Two additional TRAIL receptors, DcR1/TRAIL-R3 and DcR2/TRAIL-R4, lack functional death domains and act as decoy receptors for TRAIL. In this study, the presence of TRAIL and its receptors was investigated by immunohistochemistry in adult human testes. In addition, TRAIL and its receptors were studied in terms of protein and mRNA using western blot analysis and RT-PCR respectively. TRAIL and its receptors were immunodetected according to the different testicular cell types: TRAIL, DR5/TRAIL-R2 and DcR2/TRAIL-R4 were localized in Leydig cells, DR4/TRAIL-R1 was seen in peritubular and Sertoli cells whereas ligand and all receptors were detected in germ cells. Proteins and mRNA corresponding to TRAIL and its receptors were also identified in adult human testes. In conclusion, TRAIL and its receptors DR4/TRAIL-R1, DR5/TRAIL-R2, DcR1/TRAIL-R3 and DcR2/TRAIL-R4 are expressed in the human testis, and are predominantly localized in different germ cell types. - Source: PubMed

Kim Jin HAjaz MubasshirLokshin AnnaLee Yong J - The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL/Apo 2L) is a novel cytotoxic ligand belonging to TNF superfamily. Among TRAIL receptors, death receptor 4 (DR4) and DR5 containing death domain (DD) in their cytoplasmic region mediate apoptosis-signaling upon TRAIL binding, while decoy receptor 1 (DcR1) and DcR2 with a truncated or non-functional DD play "decoy" role. The interaction of TRAIL and TRAIL receptors plays important roles both in immunoregulation and immune pathogenesis of some diseases. In this study, we raised hybridomas secreting monoclonal antibodies against TRAIL (FMU1.1, 1.2, 1.3), DR4 (FMU1.4), DR5 (FMU1.5, 1.6), DcR1 (FMU1.7) and DcR2 (FMU1.8, 1.9). These MAbs could be used for fluorescent staining and flow cytometry (FCM) analysis as well as immunohistochemistry (IHC). Moreover, FMU1.1, 1.3, 1.4 and 1.5 could be used as coating antibodies paring corresponding polyclonal antibodies to develop sandwich ELISAs to quantitate the soluble TRAIL (sTRAIL), sDR4 or sDR5 in serum samples respectively. In addition, cross-linking of DR4/DR5 by FMU1.4 or FMU1.5 MAbs could induce apoptosis of some DR4/DR5-expressing tumor cells. Thus, this set of monoclonal antibodies against TRAIL or TRAIL receptors may be useful in expression phenotypic and functional study of TRAIL and TRAIL receptors. - Source: PubMed
Liu Xue-SongZhu YongHan Wei-NingLi Ying-NaChen Li-HuaJia WeiSong Chao-JunLiu FeiYang KunLi QiJin Bo-Quan - The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL or Apo2L) is a potent inducer of death of cancer but not normal cells, which suggests its potential use as a tumor-specific antineoplastic agent. TRAIL binds to the proapoptotic death receptors DR4 and the p53-regulated proapoptotic KILLER/DR5 as well as to the decoy receptors TRID and TRUNDD. In the present studies, we identified a subgroup of TRAIL-resistant cancer cell lines characterized by low or absent basal DR4 or high expression of the caspase activation inhibitor FLIP. Four of five TRAIL-sensitive cell lines expressed high levels of DR4 mRNA and protein, whereas six of six TRAIL-resistant cell lines expressed low or undetectable levels of DR4 (chi 2; P < 0.01). FLIP expression appeared elevated in five of six (83%) TRAIL-resistant cell lines and only one of five (20%) TRAIL-sensitive cells (chi 2; P < 0.05). Two TRAIL-resistant lines that expressed DR4 contained an A-to-G alteration in the death domain encoding arginine instead of lysine at codon 441. The K441R polymorphism is present in 20% of the normal population and can inhibit DR4-mediated cell killing in a dominant-negative fashion. The expression level of KILLER/DR5, TRID, TRUNDD or TRID, and TRUNDD did not correlate with TRAIL sensitivity (P > 0.05). These results suggest that the major determinants for TRAIL sensitivity may be the expression level of DR4 and FLIP. TRAIL-resistant cells became susceptible to TRAIL-mediated apoptosis in the presence of doxorubicin. In TRAIL-sensitive cells, caspases 8, 9, and 3 were activated after TRAIL treatment, but in TRAIL-resistant cells, they were activated only by the combination of TRAIL and doxorubicin. Our results suggest: (a) evaluation of tumor DR4 and FLIP expression and host DR4 codon 441 status could be potentially useful predictors of TRAIL sensitivity, and (b) doxorubicin, in combination with TRAIL, may effectively promote caspase activation in TRAIL-resistant tumors. - Source: PubMed
