Abstract
Severe acute respiratory syndrome (SARS) is a newly emerging infectious disease (COVID-19) caused by the novel coronavirus SARS-coronavirus 2 (CoV-2). To combat the devastating spread of SARS-CoV-2, extraordinary efforts from numerous laboratories have focused on the development of effective and safe vaccines. Traditional live-attenuated or inactivated viral vaccines are not recommended for immunocompromised patients as the attenuated virus can still cause disease via phenotypic or genotypic reversion. Subunit vaccines require repeated dosing and adjuvant use to be effective, and DNA vaccines exhibit lower immune responses. mRNA vaccines can be highly unstable under physiological conditions. On the contrary, naturally antigenic viral vectors with well-characterized structure and safety profile serve as among the most effective gene carriers to provoke immune response via heterologous gene transfer. Viral vector-based vaccines induce both an effective cellular immune response and a humoral immune response owing to their natural adjuvant properties via transduction of immune cells. Consequently, viral vectored vaccines carrying the SARS-CoV-2 spike protein have recently been generated and successfully used to activate cytotoxic T cells and develop a neutralizing antibody response. Recent progress in SARS-CoV-2 vaccines, with an emphasis on gene therapy viral vector-based vaccine development, is discussed in this review.

Abstract
Apoptosis is an ordered and orchestrated cellular process that occurs in physiological and pathological conditions. Resistance to apoptosis is a hallmark of virtually all malignancies. Despite being a cause of pathological conditions, apoptosis could be a promising target in cancer treatment. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), also known as Apo-2 ligand (Apo2L), is a member of TNF cytokine superfamily. It is a potent anti-cancer agent owing to its specific targeting towards cancerous cells, while sparing normal cells, to induce apoptosis. However, resistance occurs either intrinsically or after multiple treatments which may explain why cancer therapy fails. This review summarizes the apoptotic mechanisms via extrinsic and intrinsic apoptotic pathways, as well as the apoptotic resistance mechanisms. It also reviews the current clinically tested recombinant human TRAIL (rhTRAIL) and TRAIL receptor agonists (TRAs) against TRAIL-Receptors, TRAIL-R1 and TRAIL-R2, in which the outcomes of the clinical trials have not been satisfactory. Finally, this review discusses the current strategies in overcoming resistance to TRAIL-induced apoptosis in pre-clinical and clinical settings.

Abstract
Cell therapy is a promising new treatment option for cancer. In particular, mesenchymal stem cells (MSCs) have shown potential in delivering therapeutic genes in various tumour models and are now on the verge of being tested in the clinic. A number of therapeutic genes have been examined in this context, including the death ligand TRAIL. For cell therapy, it can be used in its natural form as a full-length and membrane-bound protein (FL-TRAIL) or as an engineered version commonly referred to as soluble TRAIL (sTRAIL). As to which is more therapeutically efficacious, contradicting results have been reported. We discovered that MSCs producing sTRAIL have significantly higher apoptosis-inducing activity than cells expressing FL-TRAIL and found that FL-TRAIL, in contrast to sTRAIL, is not secreted. We also demonstrated that TRAIL does induce the expression of pro-metastatic cytokines in prostate cancer cells, but that this effect could be overcome through combination with an AKT inhibitor. Thus, a combination consisting of small-molecule drugs specifically targeting tumour cells in combination with MSC.sTRAIL, not only provides a way of sensitising cancer cells to TRAIL, but also reduces the issue of side-effect-causing cytokine production. This therapeutic strategy therefore represents a novel targeted treatment option for advanced prostate cancer and other difficult to treat tumours.

Abstract
Clinical observations of spontaneous disease regression in some renal cell carcinoma (RCC) patients implicate a role for tumor immunity in controlling this disease. Puzzling, however, are findings that high levels of tumor infiltrating lymphocytes (TIL) are common to RCC. Despite expression of activation markers by TILs, functional impairment of innate and adaptive immune cells has been consistently demonstrated contributing to the failure of the immune system to control RCC. Immunotherapy can overcome the immunosuppressive effects of the tumor and provide an opportunity for long-term disease free survival. Unfortunately, complete response rates remain sub-optimal indicating the effectiveness of immunotherapy remains limited by tumor-specific factors and/or cell types that inhibit antitumor immune responses. Here we discuss immunotherapies and the function of multiple immune system components to achieve an effective response. Understanding these complex interactions is essential to rationally develop novel therapies capable of renewing the immune system's ability to respond to these tumors.

Abstract
TRAIL/Apo-2L is a member of the TNF superfamily first described as an apoptosis-inducing cytokine in 1995. Similar to TNF and Fas ligand, TRAIL induces apoptosis in caspase-dependent manner following TRAIL death receptor trimerization. Because tumor cells were shown to be particularly sensitive to this cytokine while normal cells/tissues proved to be resistant along with being able to synthesize and release TRAIL, it was rapidly appreciated that TRAIL likely served as one of our major physiologic weapons against cancer. In line with this, a number of research laboratories and pharmaceutical companies have attempted to exploit the ability of TRAIL to kill cancer cells by developing recombinant forms of TRAIL or TRAIL receptor agonists (e.g., receptor-specific mAb) for therapeutic purposes. In this review article we will describe the biochemical pathways used by TRAIL to induce different cell death programs. We will also summarize the clinical trials related to this pathway and discuss possible novel uses of TRAIL-related therapies. In recent years, the physiological importance of TRAIL has expanded beyond being a tumoricidal molecule to one critical for a number of clinical settings - ranging from infectious disease and autoimmunity to cardiovascular anomalies. We will also highlight some of these conditions where modulation of the TRAIL/TRAIL receptor system may be targeted in the future.

Abstract
TNF-related apoptosis-inducing ligand (TRAIL) continues to be intently studied as a cancer therapeutic because of its selective tumoricial activity. We have been interesting in evaluating the ability of TRAIL to induce systemic antitumor immunity through the generation of apoptotic tumor cells. Recent observations suggest that localized administration of TRAIL in combination with CpG ODN generates a systemic antitumor immune response to eliminate the primary tumor and distant metastases.

Abstract
It is now appreciated that there are distinct subsets of dendritic cells (DC) with specialized functions. Plasmacytoid DC (pDC) and CD8α DC can contribute to the priming, activation and function of antitumor CD8 T cells; however, their specific roles and necessity in stimulating antitumor immunity are not clearly understood. We examined the importance of pDC and CD8α DC during immunotherapy of an orthotopic model of metastatic renal cell carcinoma. Immunotherapy that utilizes a recombinant adenovirus encoding tumor necrosis factor-related apoptosis-inducing ligand (Ad5-TRAIL) in combination with an immunostimulatory CpG-containing oligodeoxynucleotide (CpG) resulted in the clearance of primary and metastatic tumors in wild-type (WT) replete BALB/c mice and prolonged survival. In comparison, mice deficient in either pDC (accomplished using a depleting mAb specific for PDCA1) or CD8α DC (through utilization of CD8α DC-deficient Batf3(-/-) BALB/c mice) had uncontrolled tumor growth and high mortality after Ad5-TRAIL/CpG administration. The ineffectiveness of Ad5-TRAIL/CpG therapy in the anti-PDCA1-treated and Batf3(-/-) BALB/c mice was marked by an altered activation phenotype of the DC, as well as significantly reduced expression of type I IFN-stimulated genes and IL-15/IL-15R complex production. In addition, pDC-depleted and Batf3(-/-) BALB/c mice had significantly decreased effector CD8 T cell infiltration in the primary tumor site compared with WT mice after therapy. These data collectively suggest that pDC and CD8α DC carry out independent, but complementary, roles that are necessary to initiate an efficacious antitumor immune response after Ad5-TRAIL/CpG therapy.

Abstract
The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising cancer therapeutic agent, which kills cancer cells selectively, while leaving normal cells unharmed. However, the emerging resistance of tumor cells and patients to TRAIL-induced apoptosis limits its further application. In this study, we developed a chimeric protein Annexin V-TRAIL (designated as TP8) with higher efficacy than TRAIL both in vitro and in vivo. In vitro, the EC50 of TP8 on a series of tumor cells was much lower than wild-type TRAIL. Annexin V provided this recombinant protein with higher efficacy, while leaving tumor specificity of TRAIL unchanged since TP8 had no effects on normal cells. Invivo, TP8 effectively suppressed tumor growth and prolonged tumor doubling time and tumor growth delay time in mouse xenografts involving multiple cancer cell types including A549, Colo205 and Bel7402. This study provides a new rational strategy to treat TRAIL-resistant cancers.

Abstract
Prostate carcinoma is the most common cancer for men and among the leading cancer-related causes. Many evidences have shown that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) potently induces apoptosis in cancer cells, and thus, is a promising biologic agent for prostate carcinoma therapy. However, TRAIL expression mediated by the current vectors lacks tumor specificity, thereby exerting cytotoxicity to normal cells. To solve this problem, we inserted miRNA response elements (MREs), miR-143 and miR-145, expression levels of which were reduced in prostate carcinoma, as well as that of miR-122, which is specifically expressed in hepatic cells, into adenoviral vectors to control TRAIL expression (Ad-TRAIL-M3). qPCR data confirmed that miR-143, miR-145, and miR-122 levels were all decreased in prostate carcinoma cell lines and prostate cancer samples from patients. Luciferase assays showed that MREs-regulated luciferase expression was potently suppressed in normal cells, but not in prostate cancer cells. Ad-TRAIL-M3, which expresses TRAIL in a MREs-regulated manner, produced high level of TRAIL and suppressed the survival of prostate cancer cells by inducing apoptosis, while Ad-TRAIL-M3 had no TRAIL expression in normal cells and thus exerted no cytotoxicity to them. The studies on PC-3 tumor xenograft in mice further confirmed that Ad-TRAIL-M3 was able to inhibit the growth of tumors and possessed high biosafety. In conclusion, we successfully generated an adenoviral vector that expresses TRAIL in miRNA-regulated mechanism. This miRNA-based gene therapy may be promising for prostate carcinoma treatment.

Abstract
Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) is a promising cancer therapeutic target due to its selective apoptosis-inducing effect in cancer cells. To efficiently deliver TRAIL to the tumor cells, an oncolytic adenovirus (p55-hTERT-HRE-TRAIL) carrying the TRAIL coding sequence was constructed. In the present study, we aimed to investigate the effect of p55-hTERT-HRE-TRAIL on the growth and metastasis of triple-negative breast cancer (TNBC). We observed that infection of the recombinant adenovirus resulted in expression of TRAIL and massive cell death in a TNBC cell line MDA-MB-231. This effect is much weaker in MCF-10A, which is a normal breast cell line. Administration of P55-HTERT-HRE-TRAIL significantly reduced orthotopic breast tumor growth and extended survival in a metastatic model. Our results suggest the oncolytic adenovirus armed with P55-HTERT-HRE-TRAIL, which exhibited enhanced anti-tumor activity and improved survival, is a promising candidate for virotherapy of TNBC.

Abstract
Background Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) functions as a cytokine to selectively kill various cancer cells without toxicity to most normal cells. Numerous studies have demonstrated the potential use of recombinant soluble TRAIL as a cancer therapeutic agent. We have showed previous administration of a recombinant adeno-associated virus (rAAV) vector expressing soluble TRAIL results in an efficient suppression of human tumor growth in nude mice. In the present study, we introduced Tet-On gene expression system into the rAAV vector to control the soluble TRAIL expression and evaluate the efficiency of the system in cancer gene therapy. Methods Controllability of the Tet-On system was determined by luciferase activity assay, and Western blotting and enzyme-linked immunoabsorbent assay. Cell viability was determined by MTT assay. The breast cancer xenograft animal model was established and recombinant virus was administrated through tail vein injection to evaluate the tumoricidal activity. Results The expression of soluble TRAIL could be strictly controlled by the Tet-On system in both normal and cancer cells. Transduction of human cancer cell lines with rAAV-TRE-TRAIL&rAAV-Tet-On under the presence of inducer doxycycline resulted in a considerable cell death by apoptosis. Intravenous injection of the recombinant virus efficiently suppressed the growth of human breast carcinoma in nude mice when activated by doxycycline. Conclusion These data suggest that rAAV-mediated soluble TRAIL expression under the control of the Tet-On system is a promising strategy for breast cancer therapy.

Abstract
Activation-induced cell death is a natural process that prevents tissue damages from over-activated immune cells. TNF-Related apoptosis ligand (TRAIL), a TNF family member, induces apoptosis of infected and tumor cells by binding to one of its two death receptors, DR4 or DR5. TRAIL was reported to be secreted by phytohemagglutinin (PHA)-stimulated CD4(+) T cells in microvesicles.We investigate here TRAIL and DR5 regulation by activated primary CD4(+) T cells and its consequence on cell death. We observed that PHA induced CD4(+) T cell apoptosis in a dose-dependent manner. Thus, we investigated molecules involved in PHA-mediated cell death and demonstrated that TRAIL and DR5 were over-expressed on the plasma membrane of PHA-stimulated CD4(+) T cells. Surprisingly, DR5 was constitutively expressed in naive CD4(+) T cells at messenger RNA (mRNA) and protein levels. Thus, using 3 dimensional microscopy and intracellular staining assays, we show that DR5 is constitutively expressed in CD4(+) T cells and is pre-stocked in the cytoplasm. When cells are stimulated by PHA, DR5 is relocalized from cytoplasm to plasma membrane. Small interference RNA (siRNA) and blocking antibody assays demonstrate that TRAIL/DR5 interaction is mainly responsible for PHA-mediated CD4(+) T cell apoptosis. Thus, membrane DR5 expression leading to TRAIL-mediated apoptosis may represent one of the pathways responsible for eradication of over-activated CD4(+) T cells during immune responses.

Abstract
Objective The objective of this study was to evaluate the anti-tumor effects of Ad/gTRAIL (an adenoviral vector in which expression of GFP and TRAIL is driven by a human telomerase reverse transcriptase promoter, hTERT) on malignant meningiomas and gliomas. Background Gliomas and meningiomas are the two most common types of human brain tumors. Currently there is no effective cure for recurrent malignant meningiomas or for gliomas. Ad/gTRAIL has been shown to be effective in killing selected lung, colon and breast cancer cells, but there have been no studies reporting its antitumor effects on malignant meningiomas. Therefore, we tested the antitumor effect of Ad/gTRAIL for the first time in human malignant meningioma and glioma cell lines, and in intracranial M6 and U87 xenografts. Methods Materials and Methods: Human malignant meningioma and glioma cells were infected with adenoviruses, Ad/gTRAIL and Ad/CMV-GFP. Cell viability was determined by proliferation assay. FACS analysis and quantification of TRAIL were used to measure apoptosis in these cells. We injected Ad/gTRAIL viruses in intracranial M6 and U87 xenografts, and measured the brain tumor volume, quantified apoptosis by TUNEL assay in the brain tumor tissue. Results Our studies demonstrate that in vitro/in vivo treatment with Ad/gTRAIL virus resulted in significant increase of TRAIL activity, and elicited a greater tumor cell apoptosis in malignant brain tumor cells as compared to treatment with the control, Ad/CMV-GFP virus without TRAIL activity. Conclusions We showed for the first time that adenovirus Ad/gTRAIL had significant antitumor effects against high grade malignant meningiomas as well as gliomas. Although more work needs to be done, our data suggests that Ad/gTRAIL has the potential to be useful as a tool against malignant brain tumors.

Abstract
Cancer is the second-leading cause of death in the U.S. behind heart disease and over stroke. The hallmarks of cancer comprise six biological capabilities acquired during the multistep development of human tumors. The inhibition of cell death pathways is one of these tumor characteristics which also include sustained proliferative signaling, evading growth suppressor signaling, replicative immortality, angiogenesis, and promotion of invasion and metastasis. Cell death is mediated through death receptor (DR) stimulation initiated by specific ligands that transmit signaling to the cell death machinery or through the participation of mitochondria. Cell death involving DR is mediated by the superfamily of tumor necrosis factor receptor (TNF-R) which includes TNF-R type I, CD95, DR3, TNF-related apoptosis-inducing ligand (TRAIL) receptor-1 (TRAIL-R1) and -2 (TRAIL-R2), DR6, ectodysplasin A (EDA) receptor (EDAR), and the nerve growth factor (NGF) receptor (NGFR). The expression of these receptors in healthy and tumor cells induces treatment side effects that limit the systemic administration of cell death-inducing therapies. The present review is focused on the different therapeutic strategies such as targeted antibodies or small molecules addressed to selective stimulated DR-mediated apoptosis or reduce cell proliferation in cancer cells.

Abstract
Urothelial carcinoma of the bladder accounts for approximately 5% of all cancer deaths in humans. The large majority of bladder tumors are non-muscle invasive at diagnosis, but even after local surgical therapy there is a high rate of local tumor recurrence and progression. Current treatments extend time to recurrence but do not significantly alter disease survival. The objective of the present study was to investigate the tumoricidal potential of combining the apoptosis-inducing protein TNF-related apoptosis-inducing ligand (TRAIL) with a small molecule inhibitor of apoptosis proteins (IAP) antagonist to interfere with intracellular regulators of apoptosis in human bladder tumor cells. Our results demonstrate that the IAP antagonist Compound A exhibits high binding affinity to the XIAP BIR3 domain. When Compound A was used at nontoxic concentrations in combination with TRAIL, there was a significant increase in the sensitivity of TRAIL-sensitive and TRAIL-resistant bladder tumor lines to TRAIL-mediated apoptosis. In addition, modulation of TRAIL sensitivity in the TRAIL-resistant bladder tumor cell line T24 with Compound A was reciprocated by XIAP small interfering RNA-mediated suppression of XIAP expression, suggesting the importance of XIAP-mediated resistance to TRAIL in these cells. These results suggest the potential of combining Compound A with TRAIL as an alternative therapy for bladder cancer.

Abstract
IMPORTANCE OF THE FIELD TNF-related apoptosis-inducing ligand (TRAIL) is a member of the TNF family of cytokines, which can induce apoptotic cell death in a variety of tumor cells by engaging specific death receptors, TRAIL-R1 and TRAIL-R2, while having low toxicity towards normal cells. There is interest in cancer therapy inducing cell death by activation of the death-receptor-mediated apoptotic pathway while avoiding decoy-receptor-mediated neutralization of the signal. This has led to the development of a number of receptor-specific TRAIL-variants and agonistic antibodies. Some of these soluble recombinant TRAIL and agonist antibodies targeting TRAIL-R1 and/or TRAIL-R2 are progressing in clinical trials. In addition, TRAIL-resistant tumors can be sensitized to TRAIL by a combination of TRAIL or agonistic antibodies with chemotherapeutic agents, targeted small molecules or irradiation. AREAS COVERED IN THIS REVIEW Recent advances in developing TRAIL or its agonist receptor antibodies in cancer therapy. We also discuss combination therapies in overcoming TRAIL resistance in cancer cells. WHAT THE READER WILL GAIN Knowledge of current clinical trials, the promise and obstacles in the future development of therapies affecting TRAIL signaling pathways. TAKE HOME MESSAGE Cancer therapeutics targeting the TRAIL/TRAIL receptor signaling pathway hold great promise for molecularly targeted pro-apoptotic anti-cancer therapy.

Abstract
Numerous biologic approaches are being investigated as anti-cancer therapies in an attempt to induce tumor regression while circumventing the toxic side effects associated with standard chemo- or radiotherapies. Among these, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has shown particular promise in pre-clinical and early clinical trials, due to its preferential ability to induce apoptotic cell death in cancer cells and its minimal toxicity. One limitation of TRAIL use is the fact that many tumor types display an inherent resistance to TRAIL-induced apoptosis. To circumvent this problem, researchers have explored a number of strategies to optimize TRAIL delivery and to improve its efficacy via co-administration with other anti-cancer agents. In this review, we will focus on TRAIL-based gene therapy approaches for the treatment of malignancies. We will discuss the main viral vectors that are being used for TRAIL gene therapy and the strategies that are currently being attempted to improve the efficacy of TRAIL as an anti-cancer therapeutic.

Abstract
CD95, TNFR1, TRAILR1 and TRAILR2 belong to a subgroup of TNF receptors which is characterized by a conserved cell death-inducing protein domain that connects these receptors to the apoptotic machinery of the cell. Activation of death receptors in malignant cells attracts increasing attention as a principle to fight cancer. Besides agonistic antibodies the major way to stimulate death receptors is the use of their naturally occurring "death ligands" CD95L, TNF and TRAIL. However, dependent from the concept followed to develop a death ligand-based therapy various limiting aspects have to be taken into consideration on the way to a "bedside" usable drug. Problems arise in particular from the cell associated transmembrane nature of the death ligands, the poor serum half life of the soluble fragments derived from the transmembrane ligands, the ubiquitous expression of the death receptors and the existence of additional non-death receptors of the death ligands. Here, we summarize strategies how these limitations can be overcome by genetic engineering.

Abstract
Since its discovery in 1995, tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a member of the tumor necrosis factor super family, has been under intense focus because of its remarkable ability to induce apoptosis in malignant human cells while leaving normal cells unscathed. Consequently, activation of the apoptotic signaling pathway from the death-inducing TRAIL receptors provides an attractive, biologically-targeted approach to cancer therapy. A great deal of research has focused on deciphering the TRAIL receptor signaling cascade and intracellular regulation of this pathway, as many human tumor cells possess mechanisms of resistance to TRAIL-induced apoptosis. This review focuses on the current state of knowledge regarding TRAIL signaling and resistance, the preclinical development of therapies targeted at TRAIL receptors and modulators of the pathway, and the results of clinical trials for cancer treatment that have emerged from this base of knowledge. TRAIL-based approaches to cancer therapy vary from systemic administration of recombinant, soluble TRAIL protein with or without the combination of traditional chemotherapy, radiation or novel anti-cancer agents to agonistic monoclonal antibodies directed against functional TRAIL receptors to TRAIL gene transfer therapy. A better understanding of TRAIL resistance mechanisms may allow for the development of more effective therapies that exploit this cell-mediated pathway to apoptosis.

Abstract
In this study, we investigated the preclinical utility and antitumor efficacy of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) delivered by Ad-IU2, a prostate-specific replication-competent adenovirus (PSRCA), against androgen-independent prostate cancer. Through transcriptional control of adenoviral early genes E1a, E1b and E4, as well as TRAIL by two bidirectional prostate-specific enhancing sequences (PSES), expression of TRAIL as well adenoviral replication was limited to prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA)-positive cells. Ad-IU2 induced 5-fold greater apoptosis selectively in PSA/PSMA-positive CWR22rv and C4-2 cells than an oncolytic adenoviral control. Furthermore, prolonged infection with Ad-IU2 reversed TRAIL resistance in LNCaP cells. Ad-IU2 exhibited superior killing efficiency in PSA/PSMA-positive prostate cancer cells at doses 5- to 8-fold lower than required by a PSRCA to produce a similar effect. This cytotoxic effect was not observed in non-prostatic cells, however. As an enhancement of its therapeutic efficacy, Ad-IU2 exerted a TRAIL-mediated bystander effect through direct cell-to-cell contact and soluble factors such as apoptotic bodies. In vivo, Ad-IU2 markedly suppressed the growth of subcutaneous androgen-independent CWR22rv xenografts compared to a PSRCA at six weeks post-treatment (3.1- vs. 17.1-fold growth of tumor). This study demonstrates the potential clinical utility of a PSRCA armed with an apoptosis-inducing ligand.

Abstract
Inducing apoptosis has become an important approach in the development of new anti-cancer treatments. Tumour necrosis factor apoptosis inducing ligand (TRAIL) based therapies have emerged as one of the most promising examples of this as they selectively induce apoptosis in tumour cells. However, many primary tumours are inherently resistant to TRAIL-mediated apoptosis and require additional sensitisation. Here we review apoptotic and non-apoptotic TRAIL-signalling, and the therapeutic effects of TRAIL-based treatments both as monotherapy and in combination with sensitising agents.

Abstract
Members of the tumor necrosis factor (TNF) superfamily influence a variety of immunological functions, including cellular activation, proliferation, and death, upon interaction with a corresponding superfamily of receptors. Whereas interest in the apoptosis-inducing molecules TNF and Fas ligand has peaked because of their participation in events such as autoimmune disorders, activation-induced cell death, immune privilege, and tumor evasion from the immune system, another death-inducing family member, TNF-related apoptosis-inducing ligand (TRAIL), or Apo-2 ligand, has generated excitement because of its unique ability to induce apoptosis in a wide range of transformed cell lines but not in normal tissues. TRAIL is well tolerated when given to healthy animals, and no observable histological or functional changes have been observed in any of the tissues or organs examined. Moreover, multiple injections of soluble TRAIL into mice beginning the day after tumor implantation can significantly suppress the growth of the tumors, with many animals becoming tumor-free. One potential drawback to these findings is that large amounts of soluble TRAIL may be required to inhibit tumor formation, possibly because of the pharmacokinetic profile of soluble TRAIL that indicates that, after intravenous injection, the majority of the protein is rapidly cleared. Increasing the in vivo half-life of recombinant soluble TRAIL or developing an alternative means of delivery may increase the relative tumoricidal activity of TRAIL such that larger, more established tumors could be eradicated as efficiently as smaller tumors. The information presented here describes the production of an adenoviral vector engineered to carry the complementary DNA (cDNA) for murine TRAIL (hTRAIL).

Abstract
The tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) is a member of the TNF superfamily which has been shown to selectively kill tumour cells, while sparing normal tissue. This attribute makes TRAIL an attractive drug candidate for cancer therapy. Although most primary tumour cells turned out to be primarily TRAIL-resistant, recent studies evidenced that a variety of cancers can be sensitised to TRAIL-induced apoptosis upon pre-treatment with chemotherapeutic agents or irradiation, while normal cells remain TRAIL-resistant. However, biomarkers that reliably predict which patients may benefit from such combinatorial therapies are required. Thus, it is essential to better understand the mechanisms underlying TRAIL resistance versus sensitivity. In this chapter, we introduce the signalling events which take place during TRAIL-induced apoptosis, describe the physiological function of TRAIL and summarise pre-clinical and clinical results obtained so far with TRAIL-receptor agonists.

Abstract
Human tumour cells are characterized by their ability to avoid the normal regulatory mechanisms of cell growth, division and death. The classical chemotherapy aims to kill tumour cells by causing DNA damage-induced apoptosis. However, as many tumour cells possess mutations in intracellular apoptosis-sensing molecules like p53, they are not capable of inducing apoptosis on their own and are therefore resistant to chemotherapy. With the discovery of the death receptors the opportunity arose to directly trigger apoptosis from the outside of tumour cells, thereby circumventing chemotherapeutic resistance. Death receptors belong to the tumour necrosis factor receptor superfamily, with tumour necrosis factor (TNF) receptor-1, CD95 and TNF-related apoptosis-inducing ligand-R1 and -R2 being the most prominent members. This review covers the current knowledge about these four death receptors, summarizes pre-clinical approaches engaging these death receptors in anti-cancer therapy and also gives an overview about their application in clinical trials conducted to date.

Abstract
CD8(+) T-cell activation via cross-presentation of antigens from apoptotic tumor cells is controversial. Dendritic cells capture naturally shed tumor antigens and cross-present them to CD8(+) T cells; unfortunately, the frequency of activated CD8(+) T cells is often too low to mount an effective response against the tumor. By increasing the amount of antigen for presentation, a larger T-cell response can be theoretically elicited. We used a recombinant adenovirus encoding full-length murine tumor necrosis factor-related apoptosis-inducing ligand (Ad5-mTRAIL) to induce tumor cell apoptosis, and when given intratumorally to mice bearing experimental renal cell carcinoma (Renca) tumors, Ad5-mTRAIL minimally prolonged survival and induced a low level of CTL activity. To enhance dendritic cell efficiency, an immunostimulatory CpG oligodeoxynucleotide (CpG ODN) was combined with Ad5-mTRAIL. This combination therapy significantly augmented in vivo antigen-specific T-cell proliferation and CTL activity, as well as prolonged survival of Renca tumor-bearing mice. Interestingly, depletion of CD4(+) or CD25(+) cells before therapy further enhanced survival and in vivo CTL activity. In addition, tumor-free mice depleted of CD4(+) cells were also able to reject a subsequent challenge of Renca cells, but not MHC-matched RM-11 prostate tumor cells, demonstrating the existence of immunologic memory. These results collectively show that local treatment with Ad5-mTRAIL and CpG ODN can augment tumor antigen cross-presentation resulting in T-cell proliferation, enhanced CTL activity, and increased animal survival.

Abstract
OBJECTIVE Tumor necrosis factor-related apoptosis inducing ligand (TRAIL) has recently been investigated because of its ability to selectively kill cancer cells. Despite recent publications mainly focusing on TRAIL resistance in cancer cells, little is known about how TRAIL contributes to the carcinogenesis process. Because the expression patterns of TRAIL and its receptors in patients with prostate carcinoma have recently been reported, this study investigated the significance of TRAIL and TRAIL receptor expression in connection to serum prostate-specific antigen (PSA) and Gleason scoring. MATERIALS AND METHODS A total of 98 patients were included in the study. Gleason scores, PSA, TRAIL, and TRAIL receptor expressions were used for the comparison purposes. The Spearman rho correlation test was administered to reveal the correlations among the variants. The Kruskal Wallis-Mann Whitney U or Friedman-Wilcoxon signed ranks test determined the statistical significance between the pairs. Multinomial and/or multiple binary logistic regression analyses were deployed to test whether TRAIL markers were independent variables to predict the prognosis of prostate cancer. Kaplan-Meier and log-rank tests were used to determine the survival rates. RESULTS High-serum PSA levels were correlated with higher levels of TRAIL and TRAIL receptor expressions. Patients with high Gleason scores had higher levels of TRAIL-R4 decoy receptor expression but lower levels of TRAIL death ligand expression. CONCLUSIONS TRAIL-R4 decoy receptor expression is strongly correlated with PSA recurrence, which is suggestive of poor prognosis. High levels of TRAIL-R4 expression but low levels of TRAIL death ligand expression are connected to decreased survival.

Abstract
We have previously described oncolytic adenovirus (Ad) vectors KD3 and KD3-interferon (IFN) that were rendered cancer-specific by mutations in the E1A region of Ad; these mutations abolish binding of E1A proteins to p300/CBP and pRB. The antitumor activity of the vectors was enhanced by overexpression of the Adenovirus Death Protein (ADP, E3-11.6K) and by replication-linked expression of IFN-alpha. We hypothesized that the anticancer efficacy of the KD3-IFN vector could be further improved by expression of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). E1-deleted Ad vectors were constructed carrying reporter genes for enhanced green fluorescent protein or secreted placental alkaline phosphatase (SEAP) and a therapeutic gene for TRAIL under control of the TetON system. Expression of the genes was increased in the presence of a helper virus and the inducer doxycycline such that up to 231-fold activation of expression for the TetON-SEAP vector was obtained. Coinfection with TetON-TRAIL augmented oncolytic activity of KD3 and KD3-IFN in vitro. Induction of TRAIL expression did not reduce the yield of progeny virus. Combination of TetON-TRAIL and KD3-IFN produced superior antitumor activity in vivo as compared with either vector alone demonstrating the efficacy of a four-pronged cancer gene therapy approach, which includes Ad oncolysis, ADP overexpression, IFN-alpha-mediated immunotherapy, and pharmacologically controlled TRAIL activity.

Abstract
Based on preclinical studies demonstrating that tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) exerts a potent and cancer cell-specific proapoptotic activity, recombinant TRAIL as well as agonistic anti-TRAIL-R1 and anti-TRAIL-R2 antibodies recently entered clinical trials. Additionally, gene therapy approaches using TRAIL-encoding adenovirus (Ad-TRAIL) are currently being developed to overcome the limitations inherent to TRAIL receptor targeting, i.e., pharmacokinetic of soluble TRAIL, pattern of receptor expression, and tumor cell resistance. To optimize gene therapy approaches, CD34+ cells transduced with Ad-TRAIL (CD34-TRAIL+) have been investigated as cellular vehicles for TRAIL delivery. Transduced cells exhibit a potent tumor killing activity on a variety of tumor cell types both in vitro and in vivo and are also cytotoxic against tumor cells resistant to soluble TRAIL. Studies in tumor-bearing nonobese diabetic/severe combined immunodeficient mice suggest that the antitumor effect of CD34-TRAIL+ cells is mediated by both direct tumor cell killing due to apoptosis and indirect tumor cell killing due to vascular-disrupting mechanisms. The clinical translation of cell and gene therapy approaches represent a challenging strategy that might achieve systemic tumor targeting and increased intratumor delivery of the therapeutic agent.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in a variety of transformed cells while sparing normal cells. To enhance the therapeutic index of soluble (s)TRAIL, we used CD34+ cells transduced with a replication-deficient adenovirus encoding the human TRAIL gene (CD34-TRAIL+) for the systemic delivery of membrane-bound (m)TRAIL to lymphoid tumors. CD34-TRAIL+ cells were evaluated for their activity in vitro and in vivo in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice xenografted with sTRAIL-sensitive and -resistant tumors. In vitro, coculturing CD34-TRAIL+ cells with sTRAIL-sensitive or -resistant lymphoma cell lines induced significant levels of caspase-dependent tumor cell death. In vivo, CD34-TRAIL+ cells significantly increased the survival of NOD/SCID mice bearing sTRAIL-sensitive or -resistant lymphoid tumors at an early or advanced stage of disease. No obvious toxicity was observed on administration of CD34-TRAIL+ cells. Histological analysis revealed high-level expression of the agonistic receptor TRAIL-R2 by tumor endothelial cells, and efficient tumor homing of transduced cells. Injection of CD34-TRAIL+ cells resulted in extensive damage of tumor vasculature followed by hemorrhagic necrosis exhibiting a perivascular distribution. These results show that CD34-TRAIL+ cells might be an efficient vehicle for mTRAIL delivery to tumors, where they exert a potent antitumor effect possibly mediated by both direct tumor cell killing and indirect vascular-disrupting mechanisms.

Abstract
Interest in TNF-related apoptosis-inducing ligand (TRAIL) as a cancer therapeutic has been high since its first description. Recently, the use of histone deacetylase inhibitors (HDACi) to treat cancer has progressed from the laboratory to the clinic, and the combination of HDACi and TRAIL is very powerful in killing human tumors. Using a panel of prostate tumor cell lines (ALVA-31, DU-145, and LNCaP) with varying TRAIL sensitivity, we examined their sensitization to a recombinant adenovirus encoding TRAIL (Ad5-TRAIL) by sodium butyrate and trichostatin A. HDACi treatment increased coxsackie-adenovirus receptor (CAR) expression, resulting in increased adenoviral infection, and increased TRAIL-mediated killing. In TRAIL-resistant DU-145 cells, HDAC inhibition also decreased protein kinase casein kinase (PKCK) 2 activity, leading to caspase-2 activation. The importance of PKCK2 and caspase-2 in DU-145 sensitization was demonstrated with the PKCK-2-specific inhibitor, which enhanced Ad5-TRAIL-induced death, or the caspase-2-specific inhibitor, zVDVAD, which blocked Ad5-TRAIL-induced death. Thus, our data highlight the connection between HDAC inhibition of PKCK2 activity and tumor cell sensitivity to TRAIL-induced apoptosis. Specifically, HDAC inhibition leads to decreased PCKC2 activity, which is followed by caspase-2 activation and partial cleavage of caspase-8 that sensitizes the tumor cell to TRAIL.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising anticancer agent, which selectively induces apoptosis in many transformed cells without apparent toxic side effects in normal tissue. We recently described the construction and characterization of a lentiviral vector for expression of TRAIL. In this report, we evaluate its suitability for therapeutic application. In vitro, we observed specific induction of apoptosis upon transduction in human lung cancer cells. Cell death was partially dependent on successful integration and TRAIL expression by the vectors, but was to some extent mediated by protein carryover, as we found TRAIL protein associated with virus particles. Transduction of subcutaneously growing lung tumors on nude mice with lentiviral TRAIL mediated a transient suppression of tumor growth. Analysis of tumor sections revealed that transduction efficiency of lentiviral control vector but not of lentiviral TRAIL vector was high. This was because of the direct cytotoxic activity of recombinant TRAIL present in viral particles, which prevented efficient tumor transduction. These data therefore suggest that enveloped viral vectors constitutively expressing TRAIL are well suited for ex vivo applications, such as the transduction of tumor-homing cells, but may have a lower effect when used directly for the transduction of tumor cells in vivo.

Abstract
Renal cell carcinoma (RCC) will cause greater than 12,000 deaths in the United States this year. The lack of effective therapy for disseminated RCC has stimulated the search for novel treatments including immunotherapeutic strategies, but poor therapeutic responses and marked toxicity have limited their use. The tumor necrosis factor (TNF) family member TNF-related apoptosis-inducing ligand (TRAIL)/Apo-2L induces apoptosis in various tumor cell types, while having little cytotoxicity against normal cells. In this study, we investigated the tumoricidal potential of a recombinant adenovirus encoding human TNFSF10 (Ad5-TRAIL), alone and in combination with a panel of histone deacetylase inhibitors (HDACi), against the TRAIL/Apo-2L-resistant RCC line 786-O and normal human renal proximal tubule epithelial cells (RPTEC). Ad5-TRAIL was unable to induce apoptosis in either 786-O or RPTEC alone; however, tumor cell apoptosis occurred when Ad5-TRAIL was combined with HDAC inhibition. Except when combined with trichostatin A, RPTEC were not sensitized to Ad5-TRAIL by HDACi. In 786-O, HDAC inhibition induced CAR expression, permitting increased adenoviral infection and transgene expression. It also induced TRAIL-R2 expression, accelerated the death-inducing signaling complex formation and enhanced caspase-8 activation. Our results demonstrate the utility of combining Ad5-TRAIL with HDACi against RCC, and mechanistically define how this combination modulates RCC sensitivity to TRAIL/Apo-2L and adenoviral infection.

Abstract
Melanoma differentiation associated gene-7 (Mda-7)/IL-24 was previously cloned into ZD55 (an adenovirus with E1B55 deleted) to form ZD55-IL-24, which had much better antitumor effect than Ad-IL-24. According to its good antitumor properties, ZD55-IL-24 has been used in preclinical studies. But ZD55-IL-24 alone still could not completely eradicate established tumors in all nude mice. It was reported that IL-24 could induce and enhance the activity of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) (a member of tumor necrosis factor (TNF) superfamily). Accordingly, the combined use of ZD55-IL-24 and ZD55-TRAIL was carried out in this study. Treatment with both ZD55-IL-24 and ZD55-TRAIL could induce more significant apoptosis in cancer cells in vitro compared with ZD55-IL-24 or ZD55-TRAIL alone. The combination of the two replicative adenoviruses had better antitumor activity in vivo than that of single oncolytic adenovirus and led to complete eradication of xenograft tumors in all treated mice. Upregulation of TRAIL was observed in tumor cells infected with ZD55-IL-24 and studies of the apoptotic cascade regulators indicate that ZD55-IL-24 could further enhance the activation of apoptosis through the TNF family of death receptors. We demonstrated for the first time the potential therapeutic effect of combined ZD55-IL-24 with ZD55-TRAIL for the targeted therapy of cancer.

Abstract
Manganese superoxide dismutase (MnSOD) is a latent tumor suppressor gene. To investigate the therapeutic effect of MnSOD and its mechanisms, a replication-competent recombinant adenovirus with E1B 55-kDa gene deletion (ZD55) was constructed, and human MnSOD and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) genes were inserted to form ZD55-MnSOD and ZD55-TRAIL. ZD55-MnSOD exhibited an inhibition in tumor cell growth approximately 1,000-fold greater than Ad-MnSOD. ZD55-TRAIL was shown to induce the MnSOD expression in SW620 cells. Accordingly, by the combined use of ZD55-MnSOD with ZD55-TRAIL (i.e., "dual gene virotherapy"), all established colorectal tumor xenografts were completely eliminated in nude mice. The evidence exists that the MnSOD overexpression led to a slower tumor cell growth both in vitro and in vivo as a result of apoptosis caused by MnSOD and TRAIL overexpression after adenoviral transduction. Our results showed that the production of hydrogen peroxide derived from MnSOD dismutation activated caspase-8, which might down-regulate Bcl-2 expression and induce Bax translocation to mitochondria. Subsequently, Bax translocation enhanced the release of apoptosis-initiating factor and cytochrome c. Cytochrome c finally triggered apoptosis by activating caspase-9 and caspase-3 in apoptotic cascade. Bax-mediated apoptosis seems to be dependent on caspase-8 activation because the inhibition of caspase-8 prevented Bid processing and Bax translocation. In conclusion, our dual gene virotherapy completely eliminated colorectal tumor xenografts via enhanced apoptosis, and this novel strategy points toward a new direction of cancer treatment.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in many transformed cells, suggesting TRAIL as an ideal candidate for cancer gene therapy. A main obstacle in cancer therapy is intrinsic or acquired therapy resistance of malignant cells. To study induction of resistance against TRAIL, we generated lentiviral vectors allowing efficient TRAIL expression and apoptosis induction in a variety of human cancer cell lines. Within days upon TRAIL overexpression, cells became resistant towards TRAIL, but not to CD95 ligation or DNA damage by cisplatin. Cell surface expression of TRAIL receptors 1 and 2 was completely abrogated in resistant cells due to intracellular retention of the receptors by TRAIL. SiRNA directed against TRAIL resensitized the resistant cells by restoring cell surface expression of TRAIL receptors. These findings represent a novel resistance mechanism towards TRAIL, specifically caused by TRAIL overexpression, and question the use of TRAIL expression in tumor-cell targeting gene therapy.

Abstract
The membrane-bound death ligands CD95L/FasL and TRAIL, which activate the corresponding death receptors CD95/Fas, TRAILR1 and TRAILR2, induce apoptosis in many tumour cells, but can also elicit an inflammatory response. This chapter focuses on the relevance of CD95L/FasL and TRAIL for the tumour surveillance function of natural killer cells and cytotoxic T-cells and discuss current concepts of utilizing these ligands in tumour therapy.

Abstract
The objective of gene therapy for the treatment of cancer is to kill tumour cells but preserve normal tissue; therefore, the ideal gene therapy agent would be targeted for specific transduction of tumour cells and have specificity in its cytotoxic action. A variety of strategies to achieve these aims have demonstrated promising results in the laboratory, including enzyme-pro-drug activating systems, correction of genetic mutations contributing to the malignant phenotype and stimulation of a T-cell-mediated anti-tumour immune response. The key to the success of all these strategies is an effective vector that can direct appropriate expression of the therapeutic gene. Viruses have many properties that can be adapted to achieve this therapeutic endpoint; furthermore, they can be engineered to replicate selectively in cancer cells and lyse them. The challenge now is to translate these features into effective therapies that can supplement or supplant existing treatments.

Abstract
Surgery, radiation or hormonal therapy are not adequate to control prostate cancer. Clearly, other novel treatment approaches, such as gene therapy, for advanced/recurrent disease are desperately needed to achieve long-term local control and particularly to develop effective systemic therapy for metastatic prostate cancer. In the last decade, significant progress in gene therapy for the treatment of localised prostate cancer has been demonstrated. A broad range of different gene therapy approaches, including cytolytic, immunological and corrective gene therapy, have been successfully applied for prostate cancer treatment in animal models, with translation into early clinical trials. In addition, a wide variety of viral and nonbiological gene delivery systems are available for basic and clinical research. Gene therapy approaches that have been developed for the treatment of prostate cancer are summarised.

Abstract
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) induces apoptosis in a number of tumorogenic or transformed cells, yet is relatively non-toxic to most normal cells, therefore, it is a promising agent for cancer therapy. However, some cancer cell lines were resistant to TRAIL cytoxicity, including MCF-7 breast cancer cells. The mechanism is not clear. Here, we report that protein kinase C delta (PKCdelta) protects MCF-7 cells from the recombinant soluble TRAIL (rsTRAIL)- mediated apoptosis. It was demonstrated that rottlerin, a PKCdelta inhibitor, sensitized MCF-7 cells to rsTRAIL cytoxicity. Combination of rottlerin and rsTRAIL inhibited PKCdelta translocation from the cytosol to membrane, and PKCdelta kinase activity on the cell membrane was kept pace with the change of PKCdelta expression. Moreover, inhibition of PKCdelta by interference RNA could facilitate apoptosis of MCF-7 cells induced by rsTRAIL. Further experiments on the signal machinery showed that rottlerin increased the sensitivity of MCF-7 cells to rsTRAIL by suppressing the transcription activity of NF-kappaB, and enhancing the caspase-processing to generate executive apoptotic signals. These findings indicate that PKCdelta functions as a survival factor protecting MCF-7 cells from the apoptosis induced by rsTRAIL.

Abstract
Tumor necrosis factor-Related Apoptosis-Inducing Ligand (TRAIL) has been reported to specifically kill malignant cells but to be relatively nontoxic to normal cells. One of disadvantages to previous in vivo protocols was the need for large quantities of TRAIL recombinant protein to suppress tumor growth. To evaluate the antitumor activity and therapeutic value of the TRAIL gene, we constructed adenoviral vectors expressing the human TRAIL gene (Ad.hTRAIL) and transferred them into malignant glioma cells in vitro and tumors in vivo, as an alternative to recombinant soluble TRAIL protein. The results show that TRAIL-sensitive glioma cells infected Ad.hTRAIL undergo apoptosis through the production and expression of TRAIL protein. The in vitro transfer elicited apoptosis, as demonstrated by the quantification of viable or apoptotic cells and by the analysis of cleavage of poly (ADP-ribose) polymerase. Furthermore, in vivo administration of Ad.hTRAIL at the site of tumor implantation suppressed the outgrowth of human glioma xenografts in SCID mice. These results further define Ad.hTRAIL as an anti-tumor therapeutic and demonstrate its potential use as an alternative approach to treatment for malignant glioma.

Abstract
The extracellular domain of the tumor necrosis factor-related apoptosis-inducing ligand (sTRAIL) may function as a soluble cytokine to selectively kill various cancer cells without toxicity to most normal cells. We constructed a series of recombinant adeno-associated virus (AAV) vectors expressing the extracellular domain of human TRAIL fused with signal peptides of human insulin, interferon, human growth hormone, and serum albumin and designated them as AAV-ISN-T, AAV-IFN-T, AAV-HGH-T, and AAV-Alb-T, respectively. Transduction of human SMMC-7721 liver cancer cells with AAV-ISN-T led to higher levels of TRAIL(95-281) protein expression in the cell culture media and produced more apoptosis of the cells in vitro than those with AAV-IFN-T, AAV-HGH-T, and AAV-Alb-T. The therapeutic potential of AAV-ISN-T was then evaluated in a transplanted mouse model established by injection of human liver cancer SMMC-7721 cells subcutaneously. Subsequent oral or intraperitoneal administration of AAV-ISN-T resulted in a rapid, high level and long time expression of soluble TRAIL in the sera and livers of the animals, as well as effective suppression of tumor growth, with no toxicity to normal hepatocytes. These data strongly suggest that it is possible to increase soluble TRAIL expression to make full use of tumoricidal activity of TRAIL as a therapeutic strategy. In conclusion, we provide evidence that oral administration of AAV-TRAIL might be an important alternative route with practical significance for cancer gene therapy.

Abstract
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), a member of the TNF family, is a type II transmembrane cytokine molecule. Soluble TRAIL has been shown to induce apoptosis in a wide variety of cancer cells in vitro and to suppress tumor growth specifically without damaging normal cells and tissues in vivo. In our previous report, we have demonstrated that an artificial gene encoding the polypeptide composed of the three functional elements (a secretion signal, a trimerization domain and an apoptosis-inducing moiety of TRAIL gene sequence) expresses and secretes highly apoptotic trimeric TRAIL into the culture supernatant. Here, as an approach to TRAIL-based cancer gene therapy, we developed an adenoviral vector delivering the gene that encodes our secretable trimeric TRAIL (stTRAIL). This adenovirus (Ad-stTRAIL) potently induced apoptosis in vitro in cancer cell lines such as HeLa, MDA-MB-231, A549, HCT116 and U-87MG. In an animal xenograft tumor model bearing a human glioma cell line U-87MG, intratumoral delivery of Ad-stTRAIL dramatically suppressed tumor growth without showing detectable adverse side effects. Histological analysis revealed that Ad-stTRAIL suppresses tumor growth by inducing apoptotic cell death. Contrary to the known rapid clearance of systemically delivered TRAIL protein from the blood circulation, stTRAIL expressed by Ad-stTRAIL in tumor tissues persisted for more than 4 days. In a comparison of tumor suppressor activity between Ad-stTRAIL and Ad-flTRAIL (delivering the full-length TRAIL gene) after mixing infected cells with uninfected cells and implanting these mixed cells in nude mice, Ad-stTRAIL showed higher tumor suppressor activity than that of Ad-flTRAIL. Our data reveal that a gene therapy using Ad-stTRAIL has a promising potential to treat human cancers including gliomas.

Abstract
To evaluate the tumoricidal activity of tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) on disseminated liver metastatic tumors, we constructed a recombinant adeno-associated virus (rAAV) expressing the extracellular domain (95-281aa) of human TRAIL (TRAIL(95-281), and the recombinant virus was designated as rAAV-TRAIL) using the 3-plasmid, helper-virus-free, packaging system. Transduction of mouse lymphoma EL-4 cells and Jurkat T cells lead to the expression of TRAIL(95-281) protein in both virus-transduced cells and the culture media, along with apoptosis of these cells in vitro. The therapeutic potential of rAAV-TRAIL was then evaluated in an orthotopic transplanted mouse model mimicking liver cancer metastasis, which was established by injection of EL-4 cells into the liver of C57BL/6 mice via the hepatic portal veins. Subsequent intraportal vein injection of rAAV-TRAIL, not the control virus, into the liver of these mice resulted in significant suppression of tumor growth and prolonged survival, while normal hepatocyte toxicity is undetectable. Histological and biochemical analysis in tumor tissue and serum confirmed that TRAIL(95-281) was stably expressed in relatively high level in hepatocytes and was secreted into the serum in active trimeric form. Futhermore, the mechanism for rAAV-TRAIL to inhibit tumor growth was by inducing apoptosis of the tumor cells metastasizing to the livers. These results strongly suggest that the rAAV-TRAIL-mediated gene delivery could be a promising approach for the treatment of liver metastasis cancer.

Abstract
Recombinant adeno-associated virus 2/5 (rAAV2/5), a hybrid rAAV-2 with AAV-5 capsid, seems to be a very efficient delivery vector for the transduction of the lung adenocarcinoma cell line A549. Infection of the A549 cell line with a rAAV2/5 vector encoding the extracellular domain of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL, amino acids 114-281) resulted in secretion of soluble TRAIL (sTRAIL) and induction of apoptosis in these cells. rAAV2/5-sTRAIL mediated delivery and stable expression of sTRAIL resulted in the presence of the trimeric form of sTRAIL in sera of nude mice that were implanted with s.c. or orthotopic A549 tumors. The rAAV2/5-sTRAIL transduction of the tumors resulted in a statistically significant reduction in tumor growth and prolonged survival of the tumor-bearing animals. Primary cell culture, histologic examination of the tumors, and serum analyses showed the absence of detectable TRAIL-induced toxicity in normal tissues including the liver. The successful inhibition of lung cancer growth and the absence of detectable toxicity suggest a putative role for rAAV2/5-sTRAIL(114-281) in the therapy of lung cancer.

Abstract
TRAIL (TNF-related apoptosis-inducing ligand) induces apoptosis in various tumor cell types and is under investigation as a cancer therapeutic. The development of a recombinant adenovirus encoding the full-length human TRAIL gene (Ad5-TRAIL) replaces the need for large quantities of soluble TRAIL protein in tumor suppressive therapies. However, the full potential of Ad5-TRAIL has not yet been maximized. Recent investigation of a histone deacetylase inhibitor, depsipeptide (FR901228), has demonstrated that it increases cellular susceptibility to adenovirus infection and augments adenoviral transgene expression. Thus, studies were initiated to evaluate the ability of depsipeptide to enhance the cytotoxic activity of Ad5-TRAIL against human prostate tumor cells. In vitro, depsipeptide increased expression of coxsackie-adenovirus receptor, leading to increased adenoviral infection and transgene expression. Additionally, tumor cell killing by Ad5-TRAIL was higher following depsipeptide pretreatment. More surprisingly, depsipeptide also increased prostate tumor cell sensitivity to TRAIL-induced apoptosis. Investigation into the mechanism responsible for increased TRAIL responsiveness revealed increased levels of TRAIL-R1 and -R2 in membrane lipid rafts following depsipeptide treatment. These results indicate that depsipeptide is a potent agent for enhancing the activity of Ad5-TRAIL by multiple mechanisms, allowing for a more efficient use of Ad5-TRAIL as an antitumor therapy.
